Android 6.0 permisos múltiples


161

Sé que Android 6.0 tiene nuevos permisos y sé que puedo llamarlos con algo como esto

if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE) !=
    PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(this,
        new String[] { 
            Manifest.permission.WRITE_EXTERNAL_STORAGE
        }, PERMISSION_WRITE_STORAGE);
}

Hoy vi una aplicación de Google que necesita 3 permisos: contactos, sms y cámara. Está haciendo una página 1-3 y los convoca a todos al mismo tiempo para que se activen.

¿Alguien puede decirme cómo puedo llamar a 4 permisos para activar al mismo tiempo como sms, cámara, contactos y almacenamiento?

Ejemplo (olvidé el nombre de la aplicación de google :()
La aplicación necesita sms, contactos y cámara

la aplicación me pidió (e hizo una página de diálogo 1-3) activar sms, activar contactos y luego la cámara. Entonces, esta aplicación de Google estaba llamando a los 3 permisos requeridos juntos y mi pregunta es ¿cómo puedo lograr lo mismo?


¿Puedes ser más específico o compartir lo que has visto y quieres implementar?

Llamar a los 4 permisos al mismo tiempo en Android 6.0 porque "esta" aplicación necesita 4 permisos. y esta aplicación de Google lo hizo muy inteligente al unirlos a todos y, como mencioné, hace que la página 1-3 active los 3 sobre la marcha. Entonces, ¿cómo puedo hacer lo mismo? llamando 4 permisos juntos al mismo tiempo para activarlos

Simplemente agregue todos los permisos que desee dentro de la matriz String [].

Solo incluya los 4 permisos en la ActivityCompat.requestPermissions(...)llamada y Android los ubicará automáticamente como usted mencionó.

Tengo un método auxiliar para verificar múltiples permisos y ver si alguno de ellos no está otorgado.

public static boolean hasPermissions(Context context, String... permissions) {
    if (context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                return false;
            }
        }
    }
    return true;
}

O en Kotlin:

fun hasPermissions(context: Context, vararg permissions: String): Boolean = permissions.all {
    ActivityCompat.checkSelfPermission(context, it) == PackageManager.PERMISSION_GRANTED
}

Luego solo envíalo a todos los permisos. Android solo pedirá los que necesita.

// The request code used in ActivityCompat.requestPermissions()
// and returned in the Activity's onRequestPermissionsResult()
int PERMISSION_ALL = 1; 
String[] PERMISSIONS = {
  android.Manifest.permission.READ_CONTACTS, 
  android.Manifest.permission.WRITE_CONTACTS, 
  android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
  android.Manifest.permission.READ_SMS, 
  android.Manifest.permission.CAMERA
};

if (!hasPermissions(this, PERMISSIONS)) {
    ActivityCompat.requestPermissions(this, PERMISSIONS, PERMISSION_ALL);
}

Gracias James, creo que esto es exactamente lo que necesito ... !!

Hola James, sí, ¡tu solución funciona perfecta! Muchas gracias de nuevo! acaba de cambiar DeviceUtils.Hasmarshmallow () a (android.os.Build.VERSION.SDK_INT> = Build.VERSION_CODES.M). Creo que esto es mejor
Frank

También resolvió mi problema, gracias. @Frank si esto resolvió su problema, no olvide aceptar esta respuesta para que todos puedan verla rápidamente.

@ maveň Estoy enfrentando el mismo problema. Si no concedo 1 de ellos, solicitará nuevamente todos los permisos, incluidos otros que ya he otorgado.

Me gusta cómo se ha escrito esto. Pero, ¿puede mostrar cómo maneja múltiples resultados en el método onRequestPermissionsResult ().

Aquí hay un ejemplo detallado con múltiples solicitudes de permisos:

La aplicación necesita 2 permisos al inicio. SEND_SMS y ACCESS_FINE_LOCATION (ambos se mencionan en manifest.xml).

Estoy usando Support Library v4, que está preparado para manejar Android pre-Marshmallow y, por lo tanto, no es necesario verificar las versiones de compilación.

Tan pronto como se inicia la aplicación, solicita múltiples permisos juntos. Si se otorgan ambos permisos, el flujo normal continúa.

public static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    if(checkAndRequestPermissions()) {
        // carry on the normal flow, as the case of  permissions  granted.
    }
}

private  boolean checkAndRequestPermissions() {
    int permissionSendMessage = ContextCompat.checkSelfPermission(this,
            Manifest.permission.SEND_SMS);
    int locationPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION);
    List<String> listPermissionsNeeded = new ArrayList<>();
    if (locationPermission != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.ACCESS_FINE_LOCATION);
    }
    if (permissionSendMessage != PackageManager.PERMISSION_GRANTED) {
        listPermissionsNeeded.add(Manifest.permission.SEND_SMS);
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(this, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]),REQUEST_ID_MULTIPLE_PERMISSIONS);
        return false;
    }
    return true;
}

ContextCompat.checkSelfPermission (), ActivityCompat.requestPermissions (), ActivityCompat.shouldShowRequestPermissionRationale () son parte de la biblioteca de soporte.

En caso de que no se otorguen uno o más permisos, ActivityCompat.requestPermissions () solicitará permisos y el control irá al método de devolución de llamada onRequestPermissionsResult ().

Debe verificar el valor del indicador shouldShowRequestPermissionRationale () en el método de devolución de llamada onRequestPermissionsResult ().

Solo hay dos casos: -

Caso 1: -Cada vez que el usuario haga clic en Denegar permisos (incluida la primera vez), se devolverá verdadero. Entonces, cuando el usuario lo niega, podemos mostrar más explicaciones y seguir preguntando nuevamente

Caso 2: -Solo si el usuario selecciona "nunca pregunta de nuevo", devolverá falso. En este caso, podemos continuar con una funcionalidad limitada y guiar al usuario a activar los permisos desde la configuración para obtener más funcionalidades, o podemos finalizar la configuración, si los permisos son triviales para la aplicación.

pero muestra todos los diálogos de permisos varias veces
Harsha

Usted dice "Debe verificar el valor del indicador shouldShowRequestPermissionRationale () en el método de devolución de llamada onRequestPermissionsResult ()", pero developer.android.com/training/permissions/requesting.html aconseja llamar a shouldShowRequestPermissionRationale () antes de solicitar permisos. Estoy confundido. Su código parece más razonable pero nunca se sabe con Google ...

Es fácil, hazlo de esta manera

private static final int REQUEST_READ_PHONE_STATE = 110 , REQUEST_ACCESS_FINE_LOCATION = 111, REQUEST_WRITE_STORAGE = 112;

En tu onCreate

 //request permission
    boolean hasPermissionPhoneState = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.READ_PHONE_STATE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionPhoneState) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                REQUEST_READ_PHONE_STATE);
    }

    boolean hasPermissionLocation = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionLocation) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                REQUEST_ACCESS_FINE_LOCATION);
    }

    boolean hasPermissionWrite = (ContextCompat.checkSelfPermission(getApplicationContext(),
            Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED);
    if (!hasPermissionWrite) {
        ActivityCompat.requestPermissions(LoginActivity.this,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                REQUEST_WRITE_STORAGE);
    }

Luego verifique el resultado

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    switch (requestCode)
    {
        case REQUEST_READ_PHONE_STATE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your phone state. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
        case REQUEST_ACCESS_FINE_LOCATION: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to get your location. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }

        case REQUEST_WRITE_STORAGE: {
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(LoginActivity.this, "Permission granted.", Toast.LENGTH_SHORT).show();
                //reload my activity with permission granted or use the features what required the permission
                finish();
                startActivity(getIntent());
            } else
            {
                Toast.makeText(LoginActivity.this, "The app was not allowed to write to your storage. Hence, it cannot function properly. Please consider granting it this permission", Toast.LENGTH_LONG).show();
            }
        }
    }

}

Esto funcionó perfectamente para mí ... solo una pregunta, ¿podemos deshabilitar los eventos táctiles fuera de los diálogos de alerta cuando aparecen estos diálogos de alerta? Porque en mi caso quiero que los usuarios permitan permisos y luego solo accedan a la aplicación.

@YogeshPatel En cualquier momento amigo ... cuando aparecen estos cuadros de diálogo de alerta, el toque externo se desactiva automáticamente, excepto la barra de estado . entonces solo tiene dos opciones: NEGAR o PERMITIR. No olvide agregar todos los permisos a su actividad Principal. Puede ocultar la barra de estado, verifique Ocultar la barra de estado

Mi enfoque se basa en la respuesta de Nicks y espero que sea un poco más utilizable para múltiples (tantos como sea necesario, no solo dos) permisos. Sugiere agregar la clase PermissionsHelper de responsabilidad única:

import android.app.Activity;
import android.app.AlertDialog;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.util.Log;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class PermissionsHelper {

private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.

public void checkAndRequestPermissions(Activity activity, String... permissions) {
    List<String> listPermissionsNeeded = new ArrayList<>();
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(permission);
        }
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
    }
}

public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_ID_MULTIPLE_PERMISSIONS: {
            Map<String, Integer> perms = new HashMap<>();

            for (String permission : permissions) {
                perms.put(permission, PackageManager.PERMISSION_GRANTED);
            }

            if (grantResults.length > 0) {
                for (int i = 0; i < permissions.length; i++)
                    perms.put(permissions[i], grantResults[i]);

                boolean allPermissionsGranted = true;
                for (String permission1 : permissions) {
                    allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
                }

                if (allPermissionsGranted) {
                    Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
                } else {
                    for (String permission2 : perms.keySet())
                        if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
                            perms.remove(permission2);

                    StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
                    for (String permission : perms.keySet()) {
                        message.append(permission);
                        message.append("\n");
                    }
                    message.append("\nHence, it cannot function properly." +
                            "\nPlease consider granting it this permission in phone Settings.");

                    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
                    builder.setTitle(R.string.permission_required)
                            .setMessage(message)
                            .setPositiveButton(android.R.string.ok, (dialog, id) -> dialog.cancel());
                    AlertDialog alert = builder.create();
                    alert.show();
                }
            }
        }
    }
}

}

Si el usuario no ha otorgado uno o varios permisos requeridos, se le mostrará el mensaje detallado AlertDialog.

Ejemplo de uso en la actividad:

private PermissionsHelper permissionsHelper;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    checkPermissions();

    //any other code
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}

private void checkPermissions() {
    permissionsHelper = new PermissionsHelper();
    permissionsHelper.checkAndRequestPermissions(this,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION);
}

Espero que esto sea útil para alguien.


Buena y ordenada solución. La clase de ayuda ayuda a despejar el código principal.

Mi clase de controlador para solicitar múltiples permisos. Puedes consultar el completo usando aquí

public class RequestPermissionHandler {
    private Activity mActivity;
    private RequestPermissionListener mRequestPermissionListener;
    private int mRequestCode;

    public void requestPermission(Activity activity, @NonNull String[] permissions, int requestCode,
            RequestPermissionListener listener) {
        mActivity = activity;
        mRequestCode = requestCode;
        mRequestPermissionListener = listener;

        if (!needRequestRuntimePermissions()) {
            mRequestPermissionListener.onSuccess();
            return;
        }
        requestUnGrantedPermissions(permissions, requestCode);
    }

    private boolean needRequestRuntimePermissions() {
        return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M;
    }

    private void requestUnGrantedPermissions(String[] permissions, int requestCode) {
        String[] unGrantedPermissions = findUnGrantedPermissions(permissions);
        if (unGrantedPermissions.length == 0) {
            mRequestPermissionListener.onSuccess();
            return;
        }
        ActivityCompat.requestPermissions(mActivity, unGrantedPermissions, requestCode);
    }

    private boolean isPermissionGranted(String permission) {
        return ActivityCompat.checkSelfPermission(mActivity, permission)
                == PackageManager.PERMISSION_GRANTED;
    }

    private String[] findUnGrantedPermissions(String[] permissions) {
        List<String> unGrantedPermissionList = new ArrayList<>();
        for (String permission : permissions) {
            if (!isPermissionGranted(permission)) {
                unGrantedPermissionList.add(permission);
            }
        }
        return unGrantedPermissionList.toArray(new String[0]);
    }

    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
            @NonNull int[] grantResults) {
        if (requestCode == mRequestCode) {
            if (grantResults.length > 0) {
                for (int grantResult : grantResults) {
                    if (grantResult != PackageManager.PERMISSION_GRANTED) {
                        mRequestPermissionListener.onFailed();
                        return;
                    }
                }
                mRequestPermissionListener.onSuccess();
            } else {
                mRequestPermissionListener.onFailed();
            }
        }
    }

    public interface RequestPermissionListener {
        void onSuccess();

        void onFailed();
    }
}

La siguiente metodología trata sobre

  • pidiendo permisos dinámicamente;
  • mostrando un AlertDialog si el usuario niega algún permiso
  • bucle hasta que el usuario acepte permiso (s)

Crear una clase "estática" para los métodos de permisos

public class PermissionsUtil {
    public static final int PERMISSION_ALL = 1;

    public static boolean doesAppNeedPermissions(){
        return android.os.Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1;
    }

    public static String[] getPermissions(Context context)
            throws PackageManager.NameNotFoundException {
        PackageInfo info = context.getPackageManager().getPackageInfo(
                context.getPackageName(), PackageManager.GET_PERMISSIONS);

        return info.requestedPermissions;
    }

    public static void askPermissions(Activity activity){
        if(doesAppNeedPermissions()) {
            try {
                String[] permissions = getPermissions(activity);

                if(!checkPermissions(activity, permissions)){
                    ActivityCompat.requestPermissions(activity, permissions,
                            PERMISSION_ALL);
                }
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
    }

    public static boolean checkPermissions(Context context, String... permissions){
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null &&
                permissions != null) {
            for (String permission : permissions) {
                if (ContextCompat.checkSelfPermission(context, permission) !=
                        PackageManager.PERMISSION_GRANTED) {
                    return false;
                }
            }
        }

        switch (requestCode) {
            case PermissionsUtil.PERMISSION_ALL: {

                        if(ActivityCompat.shouldShowRequestPermissionRationale(this, permissions[i])) {
                            indexesOfPermissionsNeededToShow.add(i);

Verificando cada situación

si se deniega, se muestra un cuadro de diálogo de alerta al usuario por qué necesitamos permiso

public static final int MULTIPLE_PERMISSIONS = 1;
public static final int CAMERA_PERMISSION_REQUEST_CODE = 2;
public static final int STORAGE_PERMISSION_REQUEST_CODE = 3;

    private void askPermissions() {

Comprobación de resultados de permisos

 @Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    switch (requestCode) {
        case CAMERA_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA)) {
                // check whether camera permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();
                }
            }
            break;
        case STORAGE_PERMISSION_REQUEST_CODE:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                // check whether storage permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();
                }
            }
            break;
        case MULTIPLE_PERMISSIONS:
            if (grantResults.length > 0 && permissions[0].equals(Manifest.permission.CAMERA) && permissions[1].equals(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
                // check whether All permission granted or not.
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED) {
                    launchCamera();

                }
            }
            break;
        default:
            break;
    }
}

puedes copiar y pegar este código, funciona bien. cambiar el contexto (esto) y los permisos según usted.

No hay nada de malo en las respuestas que solicitan permisos múltiples, pero el código de resultado de permisos múltiples no se implementa con mucha elegancia y puede hacer que se compruebe el resultado de permiso incorrecto.

if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) es una lógica terrible para verificar el resultado de múltiples permisos, no sé por qué Google implementó un código tan terrible.

Es un desastre especialmente cuando revisas múltiples permisos. Digamos que usted pide CAMERA, ACCESS_FINE_LOCATIONy ACCESS_NETWORK_STATE.

Debe verificar, ACCESS_FINE_LOCATIONpero el usuario solo se otorga CAMERAen la primera ejecución y verifica, grantResults[1]pero en la segunda ejecución se ACCESS_FINE_LOCATIONconvierte en el permiso con el índice 0. Tengo tantos problemas con el usuario que no otorga todos los permisos a la vez y tengo que escribir una lógica de resultado de permiso tan inútil.

Deberías usar

   int size = permissions.length;
    boolean locationPermissionGranted = false;

    for (int i = 0; i < size; i++) {
        if (permissions[i].equals(Manifest.permission.ACCESS_FINE_LOCATION)
                && grantResults[i] == PackageManager.PERMISSION_GRANTED) {
            locationPermissionGranted = true;
        }
    }

O más simple

   if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
                == PackageManager.PERMISSION_GRANTED) {
           // Do something ...
        }

Después de ver todas las respuestas largas y complejas. Quiero publicar esta respuesta.

RxPermission es una biblioteca ampliamente utilizada ahora para pedir permiso en un código de línea.

RxPermissions rxPermissions = new RxPermissions(this);
rxPermissions
.request(Manifest.permission.CAMERA,
         Manifest.permission.READ_PHONE_STATE)
.subscribe(granted -> {
    if (granted) {
       // All requested permissions are granted
    } else {
       // At least one permission is denied
    }
});

agregar en su build.gradle

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

dependencies {
    implementation 'com.github.tbruyelle:rxpermissions:0.10.1'
    implementation 'com.jakewharton.rxbinding2:rxbinding:2.1.1'
}

¿No es esto fácil?

He implementado con éxito un código simple para permisos múltiples a la vez. Siga los pasos a continuación 1: Haga la clase Utility.java como se muestra a continuación

public class Utility {
public static final int MY_PERMISSIONS_REQUEST = 123;
@TargetApi(Build.VERSION_CODES.JELLY_BEAN)
public static boolean checkPermissions(Context context, String... permissions) {
    if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && context != null && permissions != null) {
        for (String permission : permissions) {
            if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) {
                if (ActivityCompat.shouldShowRequestPermissionRationale((Activity) context, permission)) {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                } else {
                    ActivityCompat.requestPermissions((Activity) context, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.CALL_PHONE,Manifest.permission.GET_ACCOUNTS}, MY_PERMISSIONS_REQUEST);
                }
                return false;
            }
        }
    }
    return true;
}
}

2: ahora llama

boolean permissionCheck = Utility.checkPermissions(this, Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.CALL_PHONE, Manifest.permission.GET_ACCOUNTS);  

en su Activity onCreate () o de acuerdo con su lógica.

3: Ahora verifique el permiso antes de realizar la operación para una tarea en particular

if (permissionCheck) {
 performTaskOperation();//this method what you need to perform
} else {
        Toast.makeText(this, "Need permission ON.", Toast.LENGTH_SHORT).show();
       }

4: Ahora implemente el método onRequestPermissionsResult () en su Actividad como se muestra a continuación

  @Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case Utility.MY_PERMISSIONS_REQUEST:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                if (userChoosenTask.equals("STORAGE"))
                    performTaskOperation();//this method what you need to perform
            }
            break;
    }
}

Corto y dulce :). en lo que creo

int PERMISSION_ALL = 1;
String[] PERMISSIONS = {Manifest.permission.CAMERA, Manifest.permission.WRITE_EXTERNAL_STORAGE}; // List of permissions required

public void askPermission()
{
    for (String permission : PERMISSIONS) {
        if (ActivityCompat.checkSelfPermission(this, permission) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(PERMISSIONS, PERMISSION_ALL);
            return;
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
                                       int[] grantResults) {

    switch (requestCode) {
        case 1:{
            if(grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED && grantResults[1] == PackageManager.PERMISSION_GRANTED){
                //Do your work.
            } else {
                Toast.makeText(this, "Until you grant the permission, we cannot proceed further", Toast.LENGTH_SHORT).show();
            }
            return;
        }
    }

Solo uso una matriz para lograr múltiples solicitudes, espero que ayude a alguien. (Kotlin)

    // got all permission
    private fun requestPermission(){
        var mIndex: Int = -1
        var requestList: Array<String> = Array(10, { "" } )

        // phone call Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.CALL_PHONE
        }
        // SMS Permission
        if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.SEND_SMS
        }

        // Access photos Permission
        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.READ_EXTERNAL_STORAGE
        }

        // Location Permission
        if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                && ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            mIndex ++
            requestList[mIndex] = Manifest.permission.ACCESS_FINE_LOCATION
        }

        if(mIndex != -1){
            ActivityCompat.requestPermissions(this, requestList, PERMISSIONS_REQUEST_ALL)
        }
    }


    // permission response
    override fun onRequestPermissionsResult(requestCode: Int,

Puedes usar Dexter

En build.gradleagregar:

implementation 'com.karumi:dexter:5.0.0'

Y úsalo en tu actividad como:

val requiredPermissions = when {
            Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION,
                Manifest.permission.ACCESS_BACKGROUND_LOCATION)
            else -> listOf(Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION)
        }

Dexter.withActivity(this)
     .withPermissions(
           requiredPermissions
      )
     .withListener(object : MultiplePermissionsListener {
        override fun onPermissionRationaleShouldBeShown(
             permissions: MutableList<PermissionRequest>?,
                    token: PermissionToken?
             ) {
                    /* ... */
                }


        override fun onPermissionsChecked(report: MultiplePermissionsReport) = 
             if (report.isAnyPermissionPermanentlyDenied) {
                toast("You should grant all permissions") 
             } else {
                toast("All permissions granted")

                // continue here if permission is a must

              }).check()

             // continue here if permission is not a must

Encontré que esto está en el ejemplo de permisos de tiempo de ejecución del github de Google.

 private static String[] PERMISSIONS_CONTACT = {Manifest.permission.READ_CONTACTS,
        Manifest.permission.WRITE_CONTACTS};
private static final int REQUEST_CONTACTS = 1;
ActivityCompat.requestPermissions(this, PERMISSIONS_CONTACT, REQUEST_CONTACTS);

Hola Owls gracias, pero esta no es mi pregunta. Quiero llamar a 4 permisos diferentes al mismo tiempo desde 4 grupos de permisos. Llámalos a todos juntos para que el usuario pueda activarlos a todos en un solo paso ... una aplicación de Google hace lo mismo posible
Frank

... no lo siento Búhos ... lo sé ... creo que tienes razón! Probaré esto gracias

Utilice el ayudante de esta manera (los nombres de los permisos no importan).

public class MyPermission {

private static final int PERMISSION_REQUEST_ALL = 127;

MyPermission(MainActivity mainActivity) {
    mMainActivity = mainActivity;

        return (ActivityCompat.checkSelfPermission(context, permission) == PackageManager.PERMISSION_GRANTED);
    }
    return true;
}

private static boolean hasPermissions(Context context, String... permissions) {

                return false;
            }
        }
    }
    return true;
}

private static boolean shouldShowRationale(Activity activity, String permission) {

    }

implementation 'com.github.sachinvarma:EasyPermission:1.0.1'

Cómo pedir permiso:

 List<String> permission = new ArrayList<>();
 permission.add(EasyPermissionList.READ_EXTERNAL_STORAGE);
 permission.add(EasyPermissionList.ACCESS_FINE_LOCATION);

 new EasyPermissionInit(MainActivity.this, permission);

En Kotlin:

private val id = 1
private val permissions = arrayOf(Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.ACCESS_FINE_LOCATION)
fun hasPermissions(): Boolean {
 for (perm in permissions) {
                if (ActivityCompat.checkSelfPermission(this, perm) != PackageManager.PERMISSION_GRANTED) {
                    return false
                }
            }

        return true
    }

    if(! hasPermissions()){
                   requestPermissions(this, permissions, id)
           }

Esto es lo que he hecho en mi actividad. Esperar será útil. Estoy pidiendo permisos de cámara y micrófono.
