Example

Override onActivityResult in your Activity / Fragment and call ActivityResult.onResult

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

  ActivityResult.onResult(requestCode, resultCode, data).into(this);
}

Annotate your methods and get the callback

@OnActivityResult(requestCode = 33)
void onActivityResultTestActivity() { /* Do something */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_OK })
void onActivityResultActivityOk() { /* Only do something when ok */ }

@OnActivityResult(requestCode = 1, resultCodes = { Activity.RESULT_CANCELED })
void onActivityResultActivityCanceled() { /* Only do something when canceled */ }

@OnActivityResult(requestCode = 2)
void onActivityResultPickImage(final int resultCode, final Intent intent) { /* Do something */ }

Various parameters are supported:

Where int parameters will get the resultCode and Intent parameters will get the Intent.

Note: Each annotated method shall only have one int and / or Intent variable.

In addition to that other parameter annotations are supported like:

Some examples can be found here.

The @Extra annotation is generic and works with every type mentioned above. In addition it also supports custom types which are implementing Parcelable or Serializable.

The disadvantage of @Extra is that it won't let you specify a default value therefore the other annotations do exist and should be used when needed.
