Android Marshmallow Runtime autorisations-ne fonctionne pas

Question

Je travaillais sur les autorisations d'exécution Android-M. Je voulais ajouter une autorisation de localisation à l'un de mes fragments. Voici mon code. Android demande la permission, mais même si je nie la permission, rien ne se passe, il rejette la boîte de dialogue, mais le activateGPS() fonctionne et renvoie la valeur. Merci d'avance.

if (Build.VERSION.SDK_INT >= 23) { 
     // Marshmallow+ 
     getPermissionToReadUserContacts(); 
    } else { 
     // Pre-Marshmallow 
     System.out.println("CODMOB: Device not marshmallow"); 
     activateGPS(); 
    } 


    activateGPS(); 

    return view; 
} 
private static final int LOCATION_PERMISSIONS_REQUEST = 1; 
public void getPermissionToReadUserContacts() { 
    System.out.println("CODMOB: getPermissionToReadUserContacts()"); 
    // 1) Use the support library version ContextCompat.checkSelfPermission(...) to avoid 
    // checking the build version since Context.checkSelfPermission(...) is only available 
    // in Marshmallow 
    // 2) Always check for permission (even if permission has already been granted) 
    // since the user can revoke permissions at any time through Settings 

     if (ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.ACCESS_COARSE_LOCATION) 
       != PackageManager.PERMISSION_GRANTED) { 

      // The permission is NOT already granted. 
      // Check if the user has been asked about this permission already and denied 
      // it. If so, we want to give more explanation about why the permission is needed. 
      System.out.println("CODMOB: The permission is NOT already granted."); 
      if (shouldShowRequestPermissionRationale(
        Manifest.permission.ACCESS_COARSE_LOCATION)) { 
       // Show our own UI to explain to the user why we need to read the contacts 
       // before actually requesting the permission and showing the default UI 
       System.out.println("CODMOB: We need to access location."); 
      }else{ 

      // Fire off an async request to actually get the permission 
      // This will show the standard permission request dialog UI 
      requestPermissions(new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, 
        LOCATION_PERMISSIONS_REQUEST); 

      } 
     } 
    } 

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    // Make sure it's our original READ_CONTACTS request 
    if (requestCode == LOCATION_PERMISSIONS_REQUEST) { 
     if (grantResults.length>0 && 
       grantResults[0] == PackageManager.PERMISSION_GRANTED) { 
      System.out.println("CODMOB:permission granted"); 
      activateGPS(); 
      //Toast.makeText(this, "Read Contacts permission granted", Toast.LENGTH_SHORT).show(); 
     } else { 
      System.out.println("CODMOB: permission denied"); 
      //Toast.makeText(this, "Read Contacts permission denied", Toast.LENGTH_SHORT).show(); 
     } 
    } else { 
     super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
    } 
} 

Answer 1

changer votre code pour

if (Build.VERSION.SDK_INT >= 23) { 
     // Marshmallow+ 
     getPermissionToReadUserContacts(); 
    } else { 
     // Pre-Marshmallow 
     System.out.println("CODMOB: Device not marshmallow"); 
     activateGPS(); 
    } 
    return view; 
} 

en dépit du fragment .... ajouter cette méthode dans votre activité trop

@Override 
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
     Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.containerView); 
     if (fragment != null) { 
      fragment.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     } 
    } 

Answer 2

ActivityCompat.requestPermissions(MainActivity.this, 
       new String[]{Manifest.permission.READ_EXTERNAL_STORAGE},  100); 

@Override 
public void onRequestPermissionsResult(int requestCode, 
            String permissions[], int[] grantResults)  
switch (requestCode) { 
    case 100: { 

     // If request is cancelled, the result arrays are empty. 
     if (grantResults.length > 0 
       && grantResults[0] == PackageManager.PERMISSION_GRANTED) { 

      // permission was granted, yay! Do the 
      // contacts-related task you need to do.   
     } else { 

      // permission denied, boo! Disable the 
      // functionality that depends on this permission. 
      Toast.makeText(MainActivity.this, "Permission denied to read your External storage", Toast.LENGTH_SHORT).show(); 
     } 
     return; 
     } 

    // other 'case' lines to check for other 
    // permissions this app might request 
    } 
}

if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.READ_PHONE_STATE) != 
      PackageManager.PERMISSION_GRANTED) { 
     final String[] permission = new String[]{ 
       android.Manifest.permission.WRITE_EXTERNAL_STORAGE, 
       android.Manifest.permission.READ_EXTERNAL_STORAGE, 
       android.Manifest.permission.INTERNET, 
       android.Manifest.permission.READ_PHONE_STATE, 
       android.Manifest.permission.PACKAGE_USAGE_STATS, 
       android.Manifest.permission.ACCESS_NETWORK_STATE, 
       Manifest.permission.ACCESS_COARSE_LOCATION, 
       Manifest.permission.ACCESS_FINE_LOCATION, 
     }; 
     ActivityCompat.requestPermissions(this, permission, 0); 
    } 

utilisation du code ci-dessus dans votre activité, cela peut aider.
