Continuing the theme " How to make an ActionBar? ". I did everything as advised there. And now I wonder if it is possible to do something so that if the device does not support this SDK level (in this case 11), then simply do not display the ActionBar or display it somehow differently, as they did in earlier versions. And now it is impossible to start the application on such devices at all.
PS Add to manifest
<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="11"/>
