Answer 1

The uses-feature is case sensitive and lower case, so in effect you're stating that you're using a feature that does not exist on any device.

That should be like this:

<uses-feature
    android:name="android.hardware.camera.autofocus"
    android:required="false" />

Edit : I would try removing all permissions and add these permission one by one to test it.

Answer 2

your question seems like that

Android app compatible with 0 devices

The autofocus could be your problem since it should be in lower case
