Actionbar vs menubutton

view story

http://stackoverflow.com – I have an application which runs full-screen and relies on the menu button. What I didn't realise is that devices like the Galaxy Tab use an actionbar which no longer has a menu button. My app currently loads a fragment displaying a settings menu when one touches the menu button: @Override public boolean onPrepareOptionsMenu(Menu menu) { FragmentManager lFM = getSupportFragmentManager(); SettingsDialogFragment lSettingsDialog = new SettingsDialogFragment(); lSettingsDialog.show(lFM, "Settings"); return false; } I understand it is possible to add a custom icon to the act (HowTos)
