Search Field causes app to crash

Question

I'm writing an app which is playing music (and movies later). I added some menu items like shuffle, repeat song, exit etc. and all works like a charm. But I can't get the search button working (to search for requested song name). Here are errors from log cat when I used debugger, entered app and clicked the magnifying glass/search button:

//global declaration

public SearchView mSearchView;

//try this in setup searchmethod

  public boolean onCreateOptionsMenu(Menu menu) {
        // action bar items
