Dear F-Droid Team,
Hello,
We are observing an issue with the crash report dialog (ACRA) appearing on some devices during long-term testing, and would like to better understand the underlying cause.
Background
We conducted a 4-day continuous test on approximately 200 Android devices.
During this period, 13 devices repeatedly showed the F-Droid crash report dialog.
It said “F-Droid has crashed”.
Device Information
-
Device model: rockchip px30_evb
-
Android version: 8.1
-
F-Droid version: 1.21.1
-
RAM: 1.9 GB

Logs
We were only able to capture one relevant log (it is unclear whether other occurrences share the same cause):
java.io.FileNotFoundException:
/data/user/0/org.fdroid.fdroid/app_ACRA-unapproved/2026-04-03T02:55:11.654+08:00.stacktrace (No such file or directory)

Questions
We would like to understand the root cause category behind the crash dialog behavior (application-level vs. system/hardware-related), specifically:
-
Under what conditions is the ACRA crash report dialog triggered in F-Droid?
Is it always the result of an actual application crash? -
Regarding the FileNotFoundException above:
What is the typical cause of this error in ACRA?
Does it indicate:-
a failure to generate the crash report file, or
-
that the file was removed before being accessed?
-
-
Could this issue be related to device or hardware conditions?
For example:-
storage performance or filesystem behavior
-
memory constraints
-
long-running system stability
Or is it more likely to be purely an application-level issue?
-
Thank you for your time and support.
Best regards,
