I've been almost 24 hours figuring out why the home icon wasn't showing. ![]() REMARK: the hamburger icon will only show up if the toggle.syncState() method is called. The key functions of the app bar are as follows: A dedicated space for giving your app an identity and indicating the users location in the app. ![]() The action bar provides users access to the most important action items relating to the app's current context. NOTE: these are the overridden onResume and onStop method inside the fragment. Note the use of app:showAsAction instead of android:showAsAction in the case of adding support action bar items. Private boolean mToolBarNavigationListenerIsRegistered = void onCreate(Bundle savedInstanceState) It is a convenience class in the Android media-compat library that handles ACTIONMEDIABUTTON and translates the incoming Intents into the appropriate MediaSessionCompat.Callback method calls. Navigation Bar for Android application can replace a failed and broken button for those people who has trouble using buttons or navigation bar panel is. ![]() Just go to res -> values -> styles.xml and change the base application to. If I assume you're using 4.widget.DrawerLayout in your layout, then this approach may work for you I've only tested on API 21 but given it's mostly using the support libraries, it should work (famous last words) on lower or higher targets. Hide ActionBar from the entire App using styles.xml If you want to hide Action Bar from the entire application (from all Activities and fragments), then you can use this method.
