Android UncaughtExceptionHandler that instantiates an AlertDialog breaks

As the title says,开发者_开发知识库 I have an UncaughtExceptionHandler set in my custom application class that gets set as the default when my application starts.

However, while not in the documentation I have read that you cannot instantiate a Dialog using MyApplication.this or getApplicationContext(). When I try to do it, I get a

WindowManager$BadTokenException...

I need an alternative. I have thought of making a new activity to compensate for this but would rather have it be an AlertDialog.

Is there a way I can get a valid context to my UncaughtExceptionHandler from inside MyApplication class?

Correct. The Application context is not especially useful for constructing UIs.

An AlertDialog is impossible in this case. For starters, only an activity can open a dialog, and none of your activities may be running (e.g., crash in a background service) and valid (e.g., you had one, but it's the one that crashed).
