Android Question App crashes on re-start???

[tsteward]

If I open my app. then back out of it, then re open the app it crashes.
I'm guessing something is not re-initializing maybe.

Is anyone able to make anything out of this crash report that might point me in the right direction?

Please

Where is your project upload showing the problem?

Sorry I can't upload the program its way too large was just hoping there was something in the crash report that I couldn't see.

To me this seems to be the clue:

~e:java.lang.NullPointerException: Attempt to invoke virtual method 'void anywheresoftware.b4a.objects.collections.Map.Clear()' on a null object reference

When you back out of your app, it's not actually quit. So when you return you try to clear a map, but that variable isn't available anymore. Nearby in the log b4xsearchtemplate is mentioned so I'm thinking that's also a clue.

Sorry, I don't have better input, I hope that helps somewhat at least.
