Usage

onActivityResult for Nested Fragment

In v0.10.0 onward, NestedActivityResultFragment is introduced to fix onActivityResult problem which couldn't be called on nested fragment. To use it, you have to override onActivityResult on your Activity and add a line of code:

 @Override
  protected void onActivityResult(final int requestCode, final int resultCode, final Intent data) {

super.onActivityResult(requestCode, resultCode, data);

ActivityResultBus.getInstance().postQueue(new ActivityResultEvent(requestCode, resultCode, data));

  
}

And in your fragment, you need to call getActivity().startActivityForResult(...) but not startActivityForResult(...) since we need to let all the result sent to Activity.

Lastly, override onActivityResult in your fragment in the standard way.

 public class MainFragment extends NestedActivityResultFragment {

  @Override

public void onActivityResult(int requestCode, int resultCode, Intent data) {

 super.onActivityResult(requestCode, resultCode, data);

 // Add your code here

 Toast.makeText(getActivity(), "Fragment Got it: " + requestCode + ", " + resultCode, Toast.LENGTH_SHORT).show();

}

  
}

State Saving/Restoring

Since v0.10.0, StatedFragment is now marked deprecated. Please use the traditional way documented at http://inthecheesefactory.com/blog/fragment-state-saving-best-practices/en instead
