Question

I have a problem. This code works fine on my nexus 10 android 4.2.1. But on AVD android 2.3 it gives me

NullPointerException com.example.training.ContentFragment.onCreateOptionsMenu(ContentFragment.java:97)

So I have two navigation tabs with two fragments each for one tabs.

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // Inflate the menu; this adds items to the action bar if it is present.
    activity.getSupportMenuInflater().inflate(R.menu.trainings_menu, menu);
    super.onCreateOptionsMenu(menu, inflater);
}

Can someone help me with this?

Answer 1

onCreateOptionsMenu(Menu menu, MenuInflater inflater)

this method has already brought MenuInflater refference, you don’t need to call it, simply use provided one

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.activity_main, menu);
}
