We are updating the min API Level of Makeroid apps to API 16 (Android 4.1) We are doing this, so we can better support new functions. Your Makeroid apps will be available to 99.2% of all Android devices. You are still able to set your own min API Level, but now there is no option for API 14 and API 15.
I am not sure, but I think not, because that is one of the things Android handles and not the app that is running. However you can hide the status bar.
Ah, que pena, é que penso em usar layouts materiais em meus apps e essa é uma das características desse tipo de design, mas isso não é um problema, ansioso pelo novo Makeroid!
