I have created a working demo following the above guide and tested on 2.x to 5.x

You can clone from Github

The important thing to play around is in Main Activity

    toolbar = (Toolbar) findViewById(R.id.toolbar);
    res = this.getResources();

    this.setSupportActionBar(toolbar);
    ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);
    actionBar.setHomeButtonEnabled(true);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
    { 
        ScrimInsetsFrameLayout scrimInsetsFrameLayout = (ScrimInsetsFrameLayout)
                findViewById(R.id.linearLayout);
        scrimInsetsFrameLayout.setOnInsetsCallback(this);
    } 

and the call back

@Override
public void onInsetsChanged(Rect insets) {
      Toolbar toolbar = this.toolbar;
        ViewGroup.MarginLayoutParams lp = (ViewGroup.MarginLayoutParams)
                toolbar.getLayoutParams();
        lp.topMargin = insets.top;
        int top = insets.top;
        insets.top += toolbar.getHeight();
        toolbar.setLayoutParams(lp);
        insets.top = top; // revert
}

Absolutely the Theme for V21 does the magic
