Activity not registered in the manifest Lint warning
android, android-activity, android-lint, android-studio
Solution
You'll only need to list activities that are entry points to your app in the manifest. That is, activities that are invoked with an `Intent`.
You should not have activities that are in fact not instantiable entry points. Make such activity classes `abstract`. This will also get rid of the lint warning.
Problem
I have a base activity from which I subclass several other activities. Those other activities I do register in the manifest so I can use them from within my application. However, Android inspection says, for my base activity, `"Activity not registered in the manifest"`. I see no reason to register the base activity as I never use it directly. However, maybe, I am missing something and the warning should not be ignored? Why this warning anyway?
