java.lang.RuntimeException: Unable to instantiate application, java.lang.ClassNotFoundException:

Question

I already asked to find out the solution of this issue, but I can't get good answer for me. So I'm trying to write a question more in detail.

The below error occurs sometimes for some users. I haven't seen it through several android phones which I have for testing, but I got this crush via Google developer console roughly once a week :(

I've tried to find out to solve this problem for a long time. Some people talk it might be due to an exteranl SD card stuff, or Singletone stuff.

Besides, in previous question, a thankful guy said that I should check 'name' attribute of Applcation tag in AndroidManifest.xml. But I already put the package name on it so I don't think it's the cause of the crush.

I've been testing about an external SD card that I installed my app to external SD card and then unmounted. But I couldn't re-produce.

And about Singletone stuff, My app doesn't use an instance of Custom Application class anywhere. So I think the Singletone stuff couldn't be the cause of this issue.

Even I do not know how to re-produce the crush, so I really need a document or public stuff about it.

I'm sure there's somebody who got this error and already know how to solve. Thus, please help me know what's wrong and how I can fix it. Have a nice day, Thanks.

Known bug in the Google Play store upgrade process, https://code.google.com/p/android/issues/detail?id=56296

Answer 2

This is caused due to problems on the device which is beyond your control. Even I get similar reports in dev console, but after extensive research I have concluded that you simply cannot prevent this crash from your side by using any conventional means because it is not caused by any fault in your app but a fault on user's system. You cannot control your user's system and many crashes which are caused due to unexpected behavior of the system cannot be "fixed", not by app developers.
