                    requestPermissions(new String[]{Manifest.permission.READ_CONTACTS,Manifest.permission.READ_EXTERNAL_STORAGE}, 1);                } else {
                    ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.READ_CONTACTS,Manifest.permission.READ_EXTERNAL_STORAGE}, 1);                }
            }
        } else {
        }

    }

    @Override    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);        if (requestCode == 1) {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED &&grantResults[1]== PackageManager.PERMISSION_GRANTED) {

                Toast.makeText(this, "permission granted", Toast.LENGTH_SHORT).show();

            }
