Android apps overwrite installation crash issues

The recent test reported such a problem, in the version of the installation will be reported as follows crash, test it sure enough, specific follow-up, found that the problem is required to be conditional:
1,4.0 or 4.1 system
2, over three activity in front activitystack stack
After many of my colleagues have encountered the same problem, the collection memo. There is no good solution at the moment. There is no such problem on a higher version of the system or on a lower version. There is no time for the brothers who are troubleshooting the same problem to check it out. It doesn't make much sense.
