I m developing an app that needs to look similar in all devices with    API14 when it comes to actionbar and statusbar customization  I ve finally found a solution and since it took a bit of my time I ll share it to save some of yours  We start by using an appcompat-21 dependency   Transparent Actionbar   values styles xml    lt style name  AppTheme  parent  Theme AppCompat Light  gt       lt  style gt    lt style name  AppTheme ActionBar Transparent  parent  AppTheme  gt       lt item name  android windowContentOverlay  gt  null lt  item gt       lt item name  windowActionBarOverlay  gt true lt  item gt       lt item name  colorPrimary  gt  android color transparent lt  item gt   lt  style gt    lt style name  AppTheme ActionBar  parent  AppTheme  gt       lt item name  windowActionBarOverlay  gt false lt  item gt       lt item name  colorPrimary  gt  color default yellow lt  item gt   lt  style gt     values-v21 styles xml    lt style name  AppTheme  parent  Theme AppCompat Light  gt           lt  style gt    lt style name  AppTheme ActionBar Transparent  parent  AppTheme  gt       lt item name  colorPrimary  gt  android color transparent lt  item gt   lt  style gt    lt style name  AppTheme ActionBar  parent  AppTheme  gt       lt item name  colorPrimaryDark  gt  color bg colorPrimaryDark lt  item gt       lt item name  colorPrimary  gt  color default yellow lt  item gt   lt  style gt    Now you can use these themes in your AndroidManifest xml to specify which activities will have a transparent or colored ActionBar        lt activity             android name   MyTransparentActionbarActivity              android theme   style AppTheme ActionBar Transparent   gt        lt activity             android name   MyColoredActionbarActivity              android theme   style AppTheme ActionBar   gt          Note  in API  21 to get the Actionbar transparent you need to get the Statusbar transparent too  otherwise will not respect your colour styles and will stay light-grey    Transparent Statusbar  only works with API  19    This one it s pretty simple just use the following code    protected void setStatusBarTranslucent boolean makeTranslucent            if  makeTranslucent                getWindow   addFlags WindowManager LayoutParams FLAG TRANSLUCENT STATUS             else               getWindow   clearFlags WindowManager LayoutParams FLAG TRANSLUCENT STATUS                     But you ll notice a funky result    This happens because when the Statusbar is transparent the layout will use its height  To prevent this we just need to   SOLUTION ONE  Add this line android fitsSystemWindows  true  in your layout view container of whatever you want to be placed bellow the Actionbar                        lt LinearLayout                 android fitsSystemWindows  true                  android layout width  match parent                  android layout height  match parent  gt                           lt  LinearLayout gt            SOLUTION TWO  Add a few lines to our previous method   protected void setStatusBarTranslucent boolean makeTranslucent            View v   findViewById R id bellow actionbar           if  v    null                int paddingTop   Build VERSION SDK INT  gt   Build VERSION CODES KITKAT   MyScreenUtils getStatusBarHeight this    0              TypedValue tv   new TypedValue                getTheme   resolveAttribute android support v7 appcompat R attr actionBarSize  tv  true               paddingTop    TypedValue complexToDimensionPixelSize tv data  getResources   getDisplayMetrics                 v setPadding 0  makeTranslucent   paddingTop   0  0  0                      if  makeTranslucent                getWindow   addFlags WindowManager LayoutParams FLAG TRANSLUCENT STATUS             else               getWindow   clearFlags WindowManager LayoutParams FLAG TRANSLUCENT STATUS                     Where R id bellow actionbar will be the layout container view id of whatever we want to be placed bellow the Actionbar            lt LinearLayout             android id    id bellow actionbar              android layout width  match parent              android layout height  match parent  gt                   lt  LinearLayout gt          So this is it  it think I m not forgetting something  In this example I didn t use a Toolbar but I think it ll have the same result  This is how I customize my Actionbar    Override     protected void onCreate Bundle savedInstanceState            View vg   getActionBarView            getWindow   requestFeature vg    null   Window FEATURE ACTION BAR   Window FEATURE NO TITLE            super onCreate savedInstanceState           setContentView getContentView              if  vg    null                getSupportActionBar   setCustomView vg  new ActionBar LayoutParams ViewGroup LayoutParams MATCH PARENT  ViewGroup LayoutParams MATCH PARENT                getSupportActionBar   setDisplayShowCustomEnabled true               getSupportActionBar   setDisplayShowHomeEnabled false               getSupportActionBar   setDisplayShowTitleEnabled false               getSupportActionBar   setDisplayUseLogoEnabled false                     setStatusBarTranslucent true           Note  this is an abstract class that extends ActionBarActivity Hope it helps
