Cómo obtener la ruta completa del archivo desde URI


99

Me gustaría obtener la ruta completa del archivo, desde un URI. El URI no es una imagen, pero es un archivo de música, pero si lo hago como la solución MediaStore, no funcionará si el usuario de la aplicación selecciona, por ejemplo, Astro como navegador, en lugar del reproductor de música. ¿Cómo puedo solucionar esto?

Utilizar:

String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

o

String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));

¿El archivo constructor (URI) no está definido?

El resultado de Uri :: getPath comenzará con "/", y el resultado de Uri :: toString () comenzará con "file: //" en mi máquina.

Esta respuesta es activamente dañina y no merece los votos que obtiene. Falla si el Uri es un Uri content://o cualquier otro Uri que no sea de archivo.

Causado por: java.lang.IllegalArgumentException: URI no es absoluto

No entiendo por qué esta sigue siendo la respuesta aceptada. Simplemente no funciona hoy en día.

El método PathUtil solo funcionará debajo de oreo y si es oreo, es probable que se bloquee porque en oreo no obtendremos la identificación, sino la ruta completa en data.getData (), por lo que todo lo que necesita hacer es crear un archivo de uri y obtenga su ruta de getPath () y divídala. A continuación está el código de trabajo: -

Uri uri = data.getData(); 
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).

El código anterior funcionará en oreo y si está por debajo de oreo entonces PathUtil funcionará. ¡Gracias!

String filePath=PathUtil.getPath(context,yourURI);

@ akhilesh0707 getPath () devolverá nulo para archivos de tarjeta sd externos. ¿Alguna solución para eso?

Esto no funciona con archivos descargados en Android 9: java.lang.IllegalArgumentException: URI desconocido: contenido: // descargas / public_downloads / 18

podemos acceder a la ruta usando String strPath = FileUtils.getPath (uri));

¿Tenemos una respuesta actualizada para lo mismo sin usar getExternalStorageDirectory (), @Nadeem Iqbal en desuso? -

Prueba esto.

public String getRealPathFromURI(Uri contentUri) 
{
     String[] proj = { MediaStore.Audio.Media.DATA };
     Cursor cursor = managedQuery(contentUri, proj, null, null, null);
     int column_index = cursor.getColumnIndexOrThrow(MediaStore.Audio.Media.DATA);
     cursor.moveToFirst();
     return cursor.getString(column_index);
}

Puede usar obtener la ruta del archivo de diferentes versiones de SDk

Utilice RealPathUtils para ello

public class RealPathUtils {

@SuppressLint("NewApi")
public static String getRealPathFromURI_API19(Context context, Uri uri){
    String filePath = "";
    String wholeID = DocumentsContract.getDocumentId(uri);

    // Split at colon, use second item in the array
    String id = wholeID.split(":")[1];

    String[] column = { MediaStore.Images.Media.DATA };

    // where id is equal to
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ id }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();
    return filePath;
}


@SuppressLint("NewApi")
public static String getRealPathFromURI_API11to18(Context context, Uri contentUri) {
    String[] proj = { MediaStore.Images.Media.DATA };
    String result = null;

    CursorLoader cursorLoader = new CursorLoader(
            context,
            contentUri, proj, null, null, null);
    Cursor cursor = cursorLoader.loadInBackground();

    if(cursor != null){
        int column_index =
                cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        result = cursor.getString(column_index);
    }
    return result;
}

public static String getRealPathFromURI_BelowAPI11(Context context, Uri contentUri){
    String[] proj = { MediaStore.Images.Media.DATA };
    Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
    int column_index
            = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
    cursor.moveToFirst();
    return cursor.getString(column_index);
}
}

** Ahora obtenga la ruta del archivo de URI **

 String path = null;
                if (Build.VERSION.SDK_INT < 11)
                    path = RealPathUtils.getRealPathFromURI_BelowAPI11(MainActivity.this, uri);

                    // SDK >= 11 && SDK < 19
                else if (Build.VERSION.SDK_INT < 19)
                    path = RealPathUtils.getRealPathFromURI_API11to18(MainActivity.this, uri);

                    // SDK > 19 (Android 4.4)
                else
                    path = RealPathUtils.getRealPathFromURI_API19(MainActivity.this, uri);
                Log.d(TAG, "File Path: " + path);
                // Get the file instance
                 File file = new File(path);

Gracias hombre. Eres el salvador de la vida. Pero te sugiero que mantengas esto en la esencia pública de Github. para que podamos marcar las actualizaciones de seguimiento fácilmente

Considere publicarlo en Github como biblioteca. Descubrí que es el más consistente de Android 4 a 10

Gracias funciona, pero en la memoria externa no conseguir el camino perfecto para Android L

No agregué la clase completa. revisa el enlace y usa la clase completa. Estoy seguro de que solucionará tu problema.

Sí, lo intento también, pero el mismo resultado :(

Me costó mucho intentar resolver esto en Xamarin. De las sugerencias anteriores se me ocurrió esta solución.

private string getRealPathFromURI(Android.Net.Uri contentUri)
{
    string filename = "";
    string thepath = "";
    Android.Net.Uri filePathUri;
    ICursor cursor = this.ContentResolver.Query(contentUri, null, null, null, null);

    if (cursor.MoveToFirst())
    {
        int column_index = cursor.GetColumnIndex(MediaStore.Images.Media.InterfaceConsts.Data);//Instead of "MediaStore.Images.Media.DATA" can be used "_data"
        filePathUri = Android.Net.Uri.Parse(cursor.GetString(column_index));
        filename = filePathUri.LastPathSegment;
        thepath = filePathUri.Path;
    }

    return thepath;
}

String uri_path = "file:///mnt/sdcard/FileName.mp3";
File f = new removeUriFromPath(uri_path));
public static String removeUriFromPath(String uri)
{
  return  uri.substring(7, uri.length());
}

mi hermano usando una subcadena no es una solución, ¡porque uri_path es dinámico!
