build_version

If you ever need to get the version of the OS on which your app runs, you can try this out: android.os.Build.VERSION.SDK_INT And you can use it against(for more check this out): android.os.Build.VERSION_CODES.[BASE-KITKAT]   Finally you end up with something like: if(android.os.Build.VERSION.SDK_INT == android.os.Build.VERSION_CODES.HONEYCOMB){ // do whatever you want here }
