Android Question Crash of App on Android 12 with SDK31

Derek Johnson · Aug 16, 2022

Google's testing of the latest version of my app has revealed this crash that they found on this single device:

google Pixel 6 using Android 12 (SDK 31 ) 8,192 MBarm64-v8aen_GB

Can anyone offer any insight into this?

I've also seen it myself occasionally on start up on my Pixel 3A XL with Android 12. In this case it happens before any other start up messages are logged. I'm wondering if it could be as a result of some race condition caused by a fast processor or something else with the release SDK 31.

If anyone could suggest how I could further analyse this I'd be grateful.

You can download this version of the App here:

Looks like you are using FILE:// Uris from within a webview.

file://Uris are no longer allowed. Guess you need to use Fileprovider to access such files.

Are there any calls to DoEvents, Msgbox or any other modal dialog?

Yes there were. I'm going to compile a version of the app without any of these to see if the problem persists.

Since the crash happens before there are any log messages generated, including the built in ones, I'm not sure how the Doevents calls etc would have a chance to cause the crash, but I'll rule them out anyway. I have suspicions that the problem is being caused by the use of older libraries in particular the Sliding Menu Wrapper v1,10.

Based on the error message it is probably related to those calls.
