Default Activity not found in Android Studio

Question

I just upgraded to Android Studio 0.2.8 and I am getting an error that says "Default Activity not found" when I try to edit the run configurations.

When I launch Android Studio I get this error "Access is allowed from event dispatch thread only"

The activity I am using is a fragment activity.

So far I've tried rebuilding and invalidate caches/restart. Both were of no use.

Please let me know what I can do to fix the problem.

Answer 1

Have you added ACTION_MAIN intent filter to your main activity? If you don't add this, then android won't know which activity to launch as the main activity.

ex:

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