Another InstantiationException

Question

I'm having a InstantiationException, I have searched the other answers and questions on here but can't find anything related to my problem. The app crashes on the MainActivity looking at the logcat it gives an error with this

mTitles = getResources().getStringArray(R.array.menu_items); 

I have declared it with

private String[] mTitles;

It is taken from the "Navigation Drawer" example provided by google, I'm just playing and modifying it (learning) but this problem has become a real pain.

Heres the log

If anyone can shed any light on this it would be really helpful, Thanks

EDIT

/*****************Navigation Drawer**********************/

    mTitle = mDrawerTitle = getTitle();
    mTitles = getResources().getStringArray(R.array.menu_items);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);

    // Set a custom shadow that overlays the main content when the drawer opens
    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
    // Set up the drawer's list view with items and click listener
    mDrawerList.setAdapter(new ArrayAdapter<String>(this,
            R.layout.drawer_list_item, mTitles));
    // Set the list's click listener
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener());

Answer 1

You initialized your variable mTitles; before calling onCreate() function ;)
