// Storage Permissions
final int REQUEST_EXTERNAL_STORAGE = 1;
String[] PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
// Check if we have write permission
int permission = ActivityCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(
getActivity(),
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE
);
}

return root;
