Android Question Google Crash Report - Signal 11

[Robert Valentino]

I have gotten a few of these Signal 11 crash reports (include output of one below) and have no idea on what or where to look at

Please ANY Help on where to look

I just realized that these happened around the time I was playing with a bluetooth keyboard. I did crash a few times (until I added the Keyboard option to my manifest) and way to verify that these are them (timing seems right)

Look for calls to DoEvents, Msgbox or any other modal dialogs.

 

[Robert Valentino]

Has to be in some library I am using will continue to look.
Anyway to search jar files (libraries) for any of these?
Thanks

Not sure if/how it will help you, but you can explore .jar (and many other types of Java files) with Java Decompiler: https://java-decompiler.github.io/
