It seems that as of Android 2.2, there is a new feature for sending crash reports, as mentioned in the links:
What you have described sounds like the build in feature, and as far as I know, you cannot customize this. The data will be send to the googlePlay dev account which uploaded the app. I have seen customizations made by Sense, or Custom Roms. The only way to get your own Logs, is to use the DefaultErrorHandler
you mentioned. As a good practice I would check, if you can catch the error yourself, (maybe log it somewhere). If not I would rethrow this error, to give the user a chance to give you hints , what he has done
