I am working on application which is host on android market. Sometimes (once a month ) I got a crash report:
Unable to instantiate application java.lang.C
Some other similar questions indicate that this can be a user error. "/mnt/asec/..." indicates that the app is running from the sdcard. If the sdcard is removed it could cause this error. 3rd party apps or rooted devices can probably move an app to the sdcard even if its not allowed by the manifest.
