AppCenter cannot deobfuscate Android R8 code

[DeweyReed]

What App Center service does this affect?
Crashes.

Describe the bug
With Android Studio 3.4, R8 becomes the default code shrinker. But AppCenter cannot deobfuscate R8 code with mappings.txt.

For example, the real stacktrace from logcat: at d.a.a.a.onClick(Unknown Source:0) which can be deobfuscated but the stacktrace that AppCenter captures is at d.a.a.a.onClick. Without the postfix, the stacktrace cannot be deobfuscated by AppCenter.

To Reproduce
Steps to reproduce the behavior:

1. Create a basic application using Android Studio 3.4 or higher
2. Add AppCenter Android SDK dependency
3. Throw an exception anywhere
4. Enable code shrink
5. Build the APK
6. Trigger the crash, compare stacktraces and retrace them manually.

Expected behavior
AppCenter should be able to deobfuscate the code after I switch from proguard to R8.

Smartphone (please complete the following information):

• Device: All Android Devices
• OS: All Android OS

Dexguard is not supported either #220

Thanks for filing an issue. App Center only supports ProGuard at this time. I've changed this to a feature request type so our team can monitor community support and better prioritize this in the future. We don't have any immediate plans to address this but we'll post here if there are any updates. Thanks!

I don't think this is feature because AppCenter Crashes for Android won't work out of box.🤔
Something like "Use Proguard instead of R8 or the crash reports can't be deobfuscated" probably should be added to Android docs.

the same with us, that's very important to us @winnieli1208
and should be fixed as soon as possible.

Shouldn't really be a feature request btw, it is already a persisting issue, we should be able to read crash logs from diagnostics in AppCenter even if the output APK is obfuscated via proguard / r8 method. The reason behind this is, AppCenter is the one building the apps, so it should contain the necessary file to map the obfuscation... Really should be fixed otherwise will consider other alternatives to AppCenter.

Having the same issue here. R8 should be supported when obfuscating the crash report since it is now the default code shrinker for android.

Looking forward to this issue to be fixed.

I join this feature release. R8 is the default code shrinker and should be supported.

any plan for this request? @winnieli1
