What I mean badly is when you close Android Studio but there are some demons still running in background, this will cause linking issues between projects. Or it is possible because you delete caches manually:

1
2
cd .android
rm -r build-cache

How to Solve this error?

Go to path File -> Settings -> Plugins, you will see “Android Support” is disabled. Enable this and restart Android Studio will solve this problem.
