Error in Android Studio - "Default Activity Not Found"

Hi everyone!

I have been following along closely to Ben's videos and I am getting a run error on Android Studio. First the app wouldn't run, then I checked 'Select Run/Debug Configuration' button and there was a big red X on the Android icon. When I clicked on the edit configurations window there is and error that says 'Error- Default Activity Not Found.' Also whenever I try to run the app the edit configurations tab comes up instead of the AVD Manager. This particular instance is very odd because this has never happened before ans AS was working fine yesterday.

Thanks!

Make sure you have specified the default activity in your AndroidManisfest.xml file. Within your default activity's xml<activity> section, there should be these tags:

            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>

I had this problem too and when I looked at Android Manifest. The problem was not with the intent filter, but with activities that were deleted and still in the Manifest. All you have to do is delete those activities in the manifest.
