I have seen above a crash on a console for some user.please see more details from here http://crashes.to/s/c98e1c603ef

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.mainToolBar);
        setSupportActionBar(toolbar);

        actionBar = toolbar.findViewById(R.id.zalunuActionBar);
        viewPager = findViewById(R.id.pager);
        actionBar.setTabListener(this);
        viewPager.setAdapter(new MainPagerAdapter(getFragmentManager()));
        viewPager.setOffscreenPageLimit(viewPager.getChildCount());
        viewPager.addOnPageChangeListener(this);

    }

The error is because of conflict between support libraries. You used support.v4 library and support.v7 library both. Please use only one support library then the problem will be fixed.

I have debug your error. It will be throw only in one condition as per my debug.

when you are getting null at AppCompatDelegateImplV9.java:489

final ViewGroup windowContentView = (ViewGroup) mWindow.findViewById(android.R.id.content);

so this line never be called AppCompatDelegateImplV9.java:502

contentView.setId(android.R.id.content);

which internally lead to your error. you will get cfl null at AppCompatDelegateImplV9.java:530

ContentFrameLayout cfl = (ContentFrameLayout) mSubDecor.findViewById(android.R.id.content);

and error will thrown at AppCompatDelegateImplV9.java:537

cfl.setDecorPadding(windowDecor.getPaddingLeft(),
            windowDecor.getPaddingTop(), windowDecor.getPaddingRight(),
            windowDecor.getPaddingBottom());

mWindow is set internally by android at activity init which is object of PhoneWindow

but if any one try to use your application on any other place then mobile means (in virtual machine or running some script to hack it) then it may occur that issue.

So you should check on which device that is occurring and it is also run on google certified os or not.
