error: Duplicate file. res\values\strings.xml: Original is here.

How do I resolve this issue?

It’s caused by using prime31 plugins that utilise the library project feature and including my own AndroidManifest.xml under /Plugins/Android instead of using the many AndroidManifest.xml files that exist under the library folders.

I can get it to build if I remove my own manifest but for some reason if I build my own manifest file it gives me this?

Where should I look to change my manifest file so it works or does using a manifest file under Plugins/Android cause subfolder “res” or “libs” to not merge?
