onActivityResult() not called after startActivityForResult() with Intent.ACTION_GET_CONTENT

Question

I got my main Activity which holds different Fragment's, one fragment gives the user a possibility to open a DialogFragment. That dialog opens a list of sound files and the dialog also contains a 'Add' button from which the user should be able to add her own soundfile. To do this I thought to use the standard Android file picking functionality and make use of the Intent.ACTION_GET_CONTENT. So I fire away this intent when the user presses the 'Add' button and the Android file picking functionality comes up as it should, but when I choose a file, nothing happens what so ever. I would expect the onActivityResult()of my main activity to be triggered but it doesn't, and I can't get it to work and I don't understand why this doesn't work.

public class MyDialog extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Rest omitted...
}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new AlertDialog.Builder(context)
            .setIcon(android.R.drawable.ic_dialog_info) 
            .setTitle(R.string.TONE_PROMPT_TITLE)       

            .setNeutralButton(R.string.ADD, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    Intent intent = new Intent();
                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    intent.setType("audio/mpeg");
                    getActivity().startActivityForResult(intent, ADD_SOUND_REQUEST_CODE);
                }
            })

            .create();
}

}

I have also tried to instantiate the intent the following way: Intent intent = new Intent(getActivity(), MyActivity.class); but this doesn't work either.

Any ideas would be really helpful, thanks!

Managed to figure out what the problem was... In my manifest I have declared my Activity as android:noHistory="false" and this was the problem. After setting it to android:noHistory="true" for my activity and firing my Intentthe following way it worked like a charm.

Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("audio/mpeg");           
getActivity().startActivityForResult(intent, ADD_SOUND_REQUEST_CODE);

And just like that, the onActivityResult() in my activity was triggered just as it should and after that I followed @Rohit5k2's advice on how to get my Fragment's OnActivityResult() triggered and all has worked really great!

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    MyFragment fragmentObject = getSupportFragmentManager().findFragmentById(R.id.container);
    fragmentObject.onActivityResult(requestCode, resultCode, data);
}

Thanks guys for your help!
