I want to show the 3-dot overflow menu key (next to the RecentApp virtual key) when building my app with
android:targetSdkVersion="15"
Here is my story. My app includes two lib projects (only jars + res no source), lib-a is using menu; when the app was built with target-sdk=10, works well, the 3-dot icon shows up next to RecentApp key on system navigation bar. Now lib-b got upgraded, I HAVE to build the app with target-sdk=15, but this makes lib-a UI menu disappear. I want lib-a to have menu as before.
I checked these posts, which are very helpful,
Android Action Bar menu not showing when target sdk version is greater than 10
Android theme, fullscreen and the action bar
I can neither apply ActionBarSherlock nor set target-sdk to 10. So I am wondering if using old theme (not holo theme) will help. I created a theme, derives from [android.Theme], apply to all activities in lib-a (in app's manifest xml), but no luck.
So my question is, will theme be able to solve the problem?
