In the past few weeks there are many small updates that increased the version number from 1.9.2, one-by-one, until today, 1.9.8.
Historically I intended the Bible app to be compatible with Android 1.5 and up, so no one is left behind. However, according to this chart, Android 1.5 users are only 1.9%, and most of them are old phone users, which they most likely have downloaded this or some other Bible apps, and by not supporting 1.5 anymore, won't affect them so much.
Starting 1.9.8, only Android 1.6 and up are supported. Since 1.9.7 I have also changed the target SDK version to 3.1 (Android Honeycomb), but some people gave feedback to my email saying that the menus are not accessible. It happened that when I request no title bar, Android 3.* will also hide the action bar where the menus are all located by default. Hence, the app will now detect the Android version and not hide the title bar on tablets.
A screenshot from the emulator (I do not own an Android tablet):
The menu items look like toolbar buttons on the top of the screen. Other menu items such as Suggest, Help, and About are accessible from the overflow menu on the top-right corner.
