Why do I see "No Debuggable Applications" in Android Studio Logcat while my application is running?

Open Android Studio, Go to,

Tools-> Android -> Enable ADB Integration.

Open Android Monitor,

After enabling that, everything should work properly and you can see your package name of your application.

With v1.3.1 I disabled & enabled again "Enable ADB Integration" and it worked.

Go to Android Studio, Tools, Android, Disable ADB Integration and Enable it again. Make sure you clean your project before running !
