I upgraded IntelliJ Idea from 12.0.4 to 12.10.

Now all the modules in my Android project give the error:

Error: Default Activity Not Found

I reverted back to 12.0.4 and it everything works again.

Any ideas? I think it might be an issue with a missing plugin. Since the plugin is not installed, it is not able to find the default activity. Another thing could have been a local config, but I doubt it. I deleted the configuration folder to verify and that didn't change anything.



If you see that error occur after upgrading versions of IntelliJ IDEA or Android Studio, or after Generating a new APK, you may need to refresh the IDE's cache.

File -> Invalidate Caches / Restart...

In Android Studio, right click on the project and choose Open Module Settings. Then go to the Sources tab in your module, find the src folder, right click on it and mark it as Sources (blue color).

EDIT: There is no sources tab in later versions of Android Studio, but you can edit the build.gradle file instead: (thanks for comment Josh)

There is a setting in the Settings window.

This seems to be available from version 12.1.3 only.

You can although edit the idea.vmoptions file and add a line like this at the end:


This makes the tooltip appear much faster (at least in some areas). Try by hovering on a tab in the editor pane. It will pop up very fast. Then close IntelliJ and change the value to 20000 and try again. As you will notice it will take 20 seconds (as expected).

For example try hovering over buttons as you describe in your question. By setting the delay to a very low value the tooltip appears immediately.
