ActionBarCompat + NavigationDrawerFragment doesnt work on android 4.0 and 4.1

Question

Very strange problem! I created a new project through new project wizard in android studio. I chose to include support libraries for GridLayout, Fragments, NavigationDrawer and ActionBar. In next step I chose BlankActivity Template with NavigationDrawer navigation. Wizard nicely created my project and build it without any problem.

Problem is this, when you try to run it, it works fine on Android 4.3, 4.2 and 2.3.3 but it crashes on 4.0 and 4.1.

This is the onCreateOptionsMenu in fragment

 public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        // If the drawer is open, show the global app actions in the action bar. See also
        // showGlobalContextActionBar, which controls the top-left area of the action bar.
        if (mDrawerLayout != null && isDrawerOpen()) {
            inflater.inflate(R.menu.global, menu);
            showGlobalContextActionBar();
        }
        super.onCreateOptionsMenu(menu, inflater);
    }

This one is in the MainActivity

 @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        if (!mNavigationDrawerFragment.isDrawerOpen()) {
            // Only show items in the action bar relevant to this screen
            // if the drawer is not showing. Otherwise, let the drawer
            // decide what to show in the action bar.
            getMenuInflater().inflate(R.menu.main, menu);
            restoreActionBar();
            return true;
        }
        return super.onCreateOptionsMenu(menu);
    }

Answer 1

Just ran into this same exact issue. EXACT ISSUE.

The issue is that setHasOptionsMenu(true); is called in onCreate instead of onActivityCreated in the Fragment. Seems like a bug in the Wizard if you ask me.

To solve this, move the setHasOptionsMenu(true); call from onCreate() to onActivityCreated().

This will solve the problem. By the time the call gets to Activity#onCreateOptionsMenu the fragment instance will be instantiated.

Answer 2

I resolved problem. Stack trace was tottally missleading to me...

Problem was as eee suggested in onCreateOptionsMenu() in activity...

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        if (!mNavigationDrawerFragment.isDrawerOpen()) {
            // Only show items in the action bar relevant to this screen
            // if the drawer is not showing. Otherwise, let the drawer
            // decide what to show in the action bar.
            getMenuInflater().inflate(R.menu.main, menu);
            restoreActionBar();
            return true;
        }
        return super.onCreateOptionsMenu(menu);
    }

somehow only on Android 4.1 and 4.0 mNavigationDrawerFragment is null although it's initialized in onCreate() so i put this

if(mNavigationDrawerFragment == null )
            mNavigationDrawerFragment = (NavigationDrawerFragment)
                    getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);

in both onCreate() and in onCreateOptionsMenu() method
