Probably add methods with following signatures.

errorResult(Context, String errorKey)
- result comes from errorKey

errorResult(Context, String errorKeyPrefix, Exception errorException)
- result comes from errorKeyPrefix+errorException.class.name

seriousErrorResult(Context, String errorKeyPrefix, Exception errorException)
- result comes from errorKeyPrefix+errorException.class.name


Information that should be provided for result message generation:
- key from prefix and exception name
- message parameter - i18ned resource.name (the resource that was modified)
- message parameter - exception message (some may be meaningful)
