    startActivityForResult(intent, REQUEST_CODE_GET_JSON);

And receive result populated json in onActivityResult()

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_CODE_GET_JSON && resultCode == RESULT_OK) {
        Log.d(TAG, data.getStringExtra("json"));
    }
    super.onActivityResult(requestCode, resultCode, data);
}
