I have a really strange problem. When I use ActionBarActivity after clicking on hardware menu button (device with Android 2.3) the app closes unexpectedly without any partic
I encountered the just same problem today. Please change 'com.android.tools.build:gradle:0.9.+' of a build.gradle file into 'com.android.tools.build:gradle:0.9.0' and, sync project. I think that Gradle plugin version 0.9.1 is wrong.
Reported also at Android App crashes upon menu button click, this appears to be an issue with the latest 0.9.1 version of gradle and I can confirm that it kills apps on Froyo as well as Gingerbread. Read more about a similar problem here and another report here. The issue seems to be related to a new png processor. As mentioned by uchidev, the solution for now is to use gradle 0.9.0 by changing build.gradle.
An alternate suggestion to reverting: you can add android.aaptOptions.useAaptPngCruncher = true to build.gradle.
Update 3/28/14: This bug seems to have been fixed in Android Studio 0.5.3.
