CommandInvokationFailure when attempting to build APK

Question

I get CommandInvokationFailure error when attempting to build APK. I deleted my Android SDK Build Tool and then forced to update it though Unity but that didn't change anything. When I build with a new empty project, I don't get the error. What should I do?

I've also re-downloaded the SDK from here and updated path in Unity.

I have the following installed:

• Google Play Services
• I think I installed Android Support Library - I'm not sure.
• Local Maven repository for Support Libraries (Also known as Android Support - Repository)
• Google Repository
• Android 6.0 (API 23) (this does not affect the min SDK version).

Answer 1

There should be a file called version.xml in the folder google-play-services_lib/res/values of Google Play Services.

You need to copy this into the folder Assets/Plugins/Android/res/values/ of your Unity project.
