title: setBackgroundDrawable not working properly
body: <p>In my application, I am using actionbarsherlock. I use </p>
  
  <p><code>getSupportActionBar().setBackgroundDrwable(R.drawable.test).</code> </p>
  
  <p>It works fine, the color is showed as expected, however when I go to another activity and go back to the main activity. The bar color is changed to black (in my program, I dont set black for the backgrounddrawble and just call <code>setSupportAction().setBackgroundDrawable</code> in <code>onStart()</code>). However, if I change the code to </p>
  
  <p><code>getSupportActionBar().setBackgroundDrawable(new ColorDrawable(0xff550000)));</code></p>
  
  <p>The app works fine. When I click on back button, the color is set to 0xff55000 which is expected.</p>
