AppCenter produces up to 8.16 GB of JSON files

Description

As the title says, my app uses the AppCenter Android SDK. My users have reported to me that AppCenter generates a lot of files. The problem is obvious, as shown in the following figure:

Details

1. Which SDK version are you using?
   • 4.4.3

def appCenterSdkVersion = '4.4.3'
implementation "com.microsoft.appcenter:appcenter-analytics:${appCenterSdkVersion}"
implementation "com.microsoft.appcenter:appcenter-crashes:${appCenterSdkVersion}"

2. Which OS version did you experience the issue on?
   • Android 12 and Android 13
3. What device version did you see this error on? Were you using an emulator or a physical device?
   • Google Pixel 5
4. What third party libraries are you using?
   • N/A
5. Please enable verbose logging for your app using AppCenter.setLogLevel(Log.VERBOSE) before your call to AppCenter.start(...) and include the logs here:
   • This is a user-side problem, and this operation cannot be performed.

Hi @drakeet, Thanks for getting in touch and highlighting this case.

By design, this should be covered by storage size limit, but currently it's applied only to DB. For context - these files were workaround of db value size limit in Cursor implementation (storing values bigger than ~2 MB in files), but it was missed in storage size calculation.

Marking it as bug, we'll fix it in one of the next releases.

@MatkovIvan Under what circumstances are these large data files generated?

[MatkovIvan]

As mentioned above, the value (JSON data of a log/report that SDK has to send to backend later) bigger than ~2MB stored outside of DB because of Cursor implementation limitations. SDK stores it only until successful transmission via network. As for the source of such large value - one of the known cases is a huge stack trace in an error report.
