Can't run app projects on Android Studio
One of easy way:
- Close your currently opened project to go back to the welcome screen.
- Choose Import Project (Eclipse ADT, Gradle, etc.) from the welcome screen.
- Select an Eclipse ADT project to be imported.
The best way to resolve this issue is as follows:
Clean and then rebuild your project
Make your project (it should work by now)
Check your dependencies in gradle
At the very end you can try invalidating the cache and restarting (Recommended)
The problem should be resolved by now.
