The above answers would help with the ActionBar thing  To add to it  use the following code in case you are using the Splash Screen  Use this before you set the content view       getWindow   setFlags WindowManager LayoutParams FLAG FULLSCREEN  WindowManager LayoutParams FLAG FULLSCREEN     Just to clarify  here s how you do it       super onCreate savedInstanceState       getWindow   setFlags WindowManager LayoutParams FLAG FULLSCREEN WindowManager LayoutParams FLAG FULLSCREEN                        setContentView R layout activity main     This would make your screen a full screen  i e remove the top bar where you see the network bar  etc

Check for padding attribute if the issue still exists after changing theme    Padding Issue creating a white space on top of fragment window   app window    Once you remove the padding - top value automatically the white space is removed

If you were using Theme AppCompat Light  a better equivalent would be Theme AppCompat Light NoActionBar   I found that using Theme AppCompat NoTitleBar caused my button text to be invisible so I am using Theme AppCompat Light NoActionBar    lt activity android name   Activity      android label   string app name      android theme   android style Theme AppCompat Light NoActionBar  gt       lt intent-filter gt           lt action android name  android intent action MAIN    gt           lt category android name  android intent category LAUNCHER    gt       lt  intent-filter gt   lt  activity gt

From here   Beginning with Android 3 0  API level 11   all activities that use the default theme have an ActionBar as an app bar  However  app bar features have gradually been added to the native ActionBar over various Android releases  As a result  the native ActionBar behaves differently depending on what version of the Android system a device may be using  By contrast  the most recent features are added to the support library s version of Toolbar  and they are available on any device that can use the support library   So one option is to disable ActionBar completely  in the app manifest xml file  and then add Toolbar in every page that needs an ActionBar   follow the above link for step-by-step explanation
