La respuesta correcta anterior es muy antigua, necesita algo nuevo, así que aquí está la respuesta
Como en la última actualización, tenemos soporte para Androidx, así que primero incluya la dependencia en el archivo build.gradle de su nivel de aplicación
implementation 'com.google.android.gms:play-services-location:17.0.0'
luego agregue en su archivo de manifiesto:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
no olvides pedir el consentimiento del usuario para estos permisos si estás liberando
ahora aquí está el código solo úsalo
protected void createLocationRequest() {
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(5000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
@Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
// All location settings are satisfied. The client can initialize
// location requests here.
// ...
Toast.makeText(MainActivity.this, "Gps already open",
Toast.LENGTH_LONG).show();
Log.d("location settings",locationSettingsResponse.toString());
}
});
task.addOnFailureListener(this, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
if (e instanceof ResolvableApiException) {
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
ResolvableApiException resolvable = (ResolvableApiException) e;
resolvable.startResolutionForResult(MainActivity.this,
REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException sendEx) {
// Ignore the error.
}
}
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CHECK_SETTINGS){
if(resultCode==RESULT_OK){
Toast.makeText(this, "Gps opened", Toast.LENGTH_SHORT).show();
//if user allows to open gps
Log.d("result ok",data.toString());
}else if(resultCode==RESULT_CANCELED){
Toast.makeText(this, "refused to open gps",
Toast.LENGTH_SHORT).show();
// in case user back press or refuses to open gps
Log.d("result cancelled",data.toString());
}
}
}
