Additional context Add any other context about the problem here.

This problem exists in 84.0.x in beta and stable versions, but I have found a solution

Add <boolean name="first_run_flow" value="true" /> in /data/data/package name/shared_prefs/package name_preferences.xml to avoid crash

Note that this problem does not exist for upgrades from before 83.0

[wanlyg]

I forgot, the complete preferences.xml should be `<?xml version='1.0' encoding='utf-8' standalone='yes' ?>

`,(Note the line break) other configurations will be completed after the application is started, and then you need to pay attention to configuring user groups and permissions

What you did there is bypassing the first run screen, which I shall do in the future. But I think the underlying problem is something else. Can you post your adb log when the crash happens?

[wanlyg]

Yes this is my log

No useful information there. It seems the process just got killed for no reason. This sometimes happens but will be very hard to determine the cause in this case.

Also the package name seems to be an old one? Is this .125?

[wchen342]

Anyway I will just remove the first run screen in the coming versions.

[wanlyg]

I'm sorry, I seem to be mistaken, I have found the cause of the problem. You may not need to modify your code. An xposed-based application caused a crash. It was used to limit the background activity of the application. Some of his configurations caused the crash, but this crash only appeared in 84.0.x

[wchen342]

I wonder how did you figure that out?

[wanlyg]

I tested the compatibility of the latest .125 version on the Xiaomi developer website, and the test results are all normal. So I closed Edxposed (xposed derivative), and the same problem was solved. After investigation, it was Thanox's "Task Cleanup" (this function will kill the app when the app is crossed in the background) that caused the first startup crash. The problem of closing this function was solved, so adb did not have a valid log. And it only appears in all versions of 84.0.x. I don’t know how to resolve the conflict, but the problem has been resolved. Thanox It is not open source, this link seems to be used only to collect questions

[wchen342]

I see. Closing.
