Answer 1

getSupportActionBar().setBackgroundDrawable(draw);

should be, in your case

getSupportActionBar().setBackgroundDrawable(getResources.getDrawable(R.drawable.your_drawable_name);

The Constructor of ColorDrawable takes the int that represent the color, not the id of the color. Use instenad

ColorDrawable draw = new ColorDrawable(getResources().getColor(R.color.grey));

Edit:

about the style.xml, you need both the item with and without the android prefix:

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
   <item name="android:actionBarStyle">@style/ActionBarTheme</item>  
   <item name="actionBarStyle">@style/ActionBarTheme</item>
</style>

Lint is probably going to complain about it, because of the minSDK value. if it does you can add tools:ignore="NewApi" to the item with the android: prefix. For instance:

 <item name="android:actionBarStyle" tools:ignore="NewApi">@style/ActionBarTheme</item>
