مشکل در permission.WRITE_EXTERNAL_STORAGE در اندروید 6

 
میتونی از این متد استفاده کنی ..

  public  boolean checkPermission() {

        if (Build.VERSION.SDK_INT >= 23) {
            if (checkSelfPermission(Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED && 
                checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {

                // your code

                Log.v("TAG","Permission is granted");
                return true;
            } else {

                Log.v("TAG","Permission is revoked");
                ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
                return false;
            }
        }
        else {

             // your code

            Log.v("TAG", "Permission is granted");
            return true;
        }
    }
