Override this method on your main activity

 @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    TestFrag demoFragment = (TestFrag) getSupportFragmentManager().findFragmentByTag("test");
    demoFragment.onActivityResult(requestCode, resultCode, data);
}

after your fragment activity result call
