Removing Android app permissions

I tried it and it doesn’t work for me…
The Manifest file uses the same permissions as before.

When i look in the Output Log I see this:

UATHelper: Packaging (Android (ETC1)): [proguard] Warning: can’t write resource [META-INF/MANIFEST.MF] (Duplicate zip entry [classes.jar:META-INF/MANIFEST.MF])

I don’t know what I should do with that information, but it says it can’t write the Manifest…
Does anybody know something?

Thanks in advance!
