Error while trying to emulate my app on Android


#1

Hello everyone,

I’ve been trying to solve this problem but I can’t find anything. When I’m trying to emulate my app on the Android emulator, I get this error:

Could not get unknown property 'ANDROID_SUPPORT_ANNOTATIONS_VERSION'

I’ve been looking on Google but all the problems related to this one use some plugins that I don’t.

Here’s the full output of the error:
