Answer 1

Erlaubnis externe Schreib-/Lese hinzufügen in Manifest-Datei

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> 

Answer 2

die Sie interessieren, Setzen Sie diesen Code in onCreate direkt nach setContentView und setzen Sie den restlichen Code von onCreate in anderen Teil:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 

     int hasWritePermission = checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE); 
     int hasReadPermission = checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE); 

     List<String> permissions = new ArrayList<String>(); 
     if (hasWritePermission != PackageManager.PERMISSION_GRANTED) { 
      permissions.add(Manifest.permission.WRITE_EXTERNAL_STORAGE); 
     } else { 
      preferencesUtility.setString("storage", "true"); 
     } 

     if (hasReadPermission != PackageManager.PERMISSION_GRANTED) { 
      permissions.add(Manifest.permission.READ_EXTERNAL_STORAGE); 

     } else { 
      preferencesUtility.setString("storage", "true"); 
     } 

     if (!permissions.isEmpty()) { 
      requestPermissions(permissions.toArray(new String[permissions.size()]), REQUEST_CODE_SOME_FEATURES_PERMISSIONS); 
     } 
    } 

aus Seite onCreate schreiben:

@Override 
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) { 
    switch (requestCode) { 
     case REQUEST_CODE_SOME_FEATURES_PERMISSIONS: { 
      for (int i = 0; i < permissions.length; i++) { 
       if (grantResults[i] == PackageManager.PERMISSION_GRANTED) { 
        System.out.println("Permissions --> " + "Permission Granted: " + permissions[i]); 
       } else if (grantResults[i] == PackageManager.PERMISSION_DENIED) { 
        System.out.println("Permissions --> " + "Permission Denied: " + permissions[i]); 
       } 
      } 
     } 
     break; 
     default: { 
      super.onRequestPermissionsResult(requestCode, permissions, grantResults); 
     } 
    } 
}

Ich hatte auch gleiche Problem, Haben sofern Berechtigungen wie unten in manifext.xml

**<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>**
