Android app crash in the OS layer

Question

I frequently get an app crash while the ListView is calling on the Adapter to provide backing data. Device is a Sony Experia X10 with Android 1.6. This is just a Seg fault violation, however I dont know how i can fix it?? I do not have any native components - its a pure java app.

Answer 1

You have encountered a bug in the firmware, either something specific to this device model, or possible generic to Android itself.

It is impossible to say how to work around it, since you did not supply any code or any indication of where in that code the crash occurs. You will simply need to do more testing, commenting out various bits to find what specific thing it is you are doing that is triggering the firmware bug.

You should consider posting this dump plus whatever descriptive information you can to the Android public issue tracker, as you may be able to get some answers that way.
