I already tried:
Turning off Instant Run -> Clean Build -> Turning on Again -> Run as mentioned here.
But cannot get it to work. I want to use Instant Run and hence don't want to disable it. Please help me find out why this is happening.
Go to Run -> Edit configurations. And then make sure you have Instant App Provision enable in addition with Gradle-aware Make option like below screenshot.
If not then click + and select from the list options.
- Click on Gradle (Right Side in Android Studio)
- Click Refresh
- Try Re-running the project.
