Newbie- Failed to repackage resources

So, I see this is a recurring problem. But I tried everything and havent been able to solve it yet.

I get the "failed to re-package resources" error which I assume is caused from the AndroidManifest.xml ( AndroidManifest.xml:5: error: Error: String types not allowed ) Since I began using Unity , Vuforia and the Android sdk a few hours ago, I'd say I m quite the newbie here. Anyway, I want to run a real simple scene and this is frustrating. I have unity 2017.2.0f3 -win64, JDK 9, and I tried many configurations for the android sdk. Right now I have platform tools 24, sdk tools 25.2.5 and build tools 27.0.1 (tried 23 too with the other two, didnt help).

PS: Building with minimum Android 4.4 and target Android 6.0

Please, any ideas would be welcome. I ve spent 2 hours making my whole project and it works, and after that 4 more searching for answers.. Thanks in advance!
