How to fix 'handleWindowVisibility: no activity for token android.os.BinderProxy'?

Question

I'm working on a small app, that was tested and was working great along the way. When I added new code to have the app send info to my Firebase Realtime Database, it just won't launch my app. It will flash the MainActivity for a split second then goes black.

When I remove the code I entered, itenter code here keeps on doing the same. Although the same code (after removal of what I thought was bad) was working before. I've digged through forums, and I haven't found any piece of code that references a dialog box before the activity has finished

I am expecting to after I have logged in with a user, to have that uID reference to my firebase database, and if there is no user with that uID, that it would redirect them to the SetupActivity class for more info input.

Right now the screen flashes for a split second (Iguess showing my MainActivity) then goes black.

Answer 1

I saved all my code and xml and literally pasted it into a new project, and the problem was gone. Must've run into some really obscure bug on this one.
