Force Locale

Resources res = getResources(); DisplayMetrics dm = res.getDisplayMetrics(); Configuration conf = res.getConfiguration();conf.locale = new Locale("sv", "SE");res.updateConfiguration(conf, dm);

Force locale for an application, bug in 2.0? - Kaj Bjurman"No, changing the application's locale like this is not supported, and will not entirely work. It shouldn't cause an activity to restart though... actually I can't imagine how this would cause an activity to restart, since this method is much lower-level than the activity. Maybe the process is crashing for some reason in this call? "

Crash Reporter

Since the admin console lacks crash reports consider implementing a reporter yourself. There's several out there.
