onActivityResult gets called when Activity starts,

Question

i wrote a FragmentActivity with some tabs. when i call an additional activity (which i use for setting user-preferences) with startActivityForResult (no differences if its in FragmentActivity or in ListFragment) the method onActivityResult gets called when i starts this preference-activity, but not when i finish it, as i would expect it (again no differences if its in FragmentActivity or in ListFragment). after i finish the preference-activity this method does not get called at all.

my problem is that i want to refresh my current tab (and set the last used tab id) after i finished the preference activity and i hoped to be able to do this in the onActivityResult method.

this is the class creating the preference-activity:

public abstract class ListFragmentBase<I> extends ListFragment implements
LoaderCallbacks<List<I>> {

this is the method forwarding me to the preference activity inside this class:

protected void forwardToPreferences(int currentTab){            
        Intent intent = new Intent(getActivity(), GlobalPreferencesActivity.class);
        getActivity().startActivityForResult(intent, 10);
}

this is the method that gets called after calling the method above but not after i finished the called activity

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

this is the preference-activity:

public class GlobalPreferencesActivity extends Activity {

and inside that class you see how i call the finish method:

TextView confirmSettings = (TextView) view.findViewById(R.id.confirm_settings);
confirmSettings.setTextSize(PreferenceHelper.getSizeHeader(getApplicationContext()));
    confirmSettings.findViewById(R.id.confirm_settings).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {    
            if(BaseFragmentActivity.lastActivity != null){
                BaseFragmentActivity.lastActivity.onRefreshData();
        }
            ComponentName callingActivity = getCallingActivity();
            GlobalPreferencesActivity.this.finish();
        }
    });

Answer 1

It is a bug of Android

onActivityResult() called prematurely

and

Why does result from startActivityForResult come before activity really starts?

I don't know which version you use and if it has been solved/corrected

Answer 2

onActivityResult, called after onResume,

The basic reason that when your jump from your activity to another activity without calling finish. Then last activity went in onStop state.

After onStop, onstart,onResume method call then onActivityResult called.

Answer 3

Please make sure activity your calling is not singleInstance in AndroidManifest file. Make sure that its is singleTop or standard.

Hope this will work for you guys as well
