I am working on an App which has design requirement to be built as it should only have the Title on the ActionBar and not the App Icon. i tried various solutions found from
Its quite tricky anyhow, but i solved it,and it works like a charm in all devices.
I made a 2x2 px transparant icon and added it as
ActionBar actionBar = getActionBar();
actionBar.setIcon(R.drawable.actionbar_null_icon);
and removed the code
getActionBar().setDisplayUseLogoEnabled(false);
getActionBar().setDisplayShowHomeEnabled(false);
thanks to nDroidDev for suport
