发布前报告“问题：本机崩溃”

Question

Google Play Console Pre-launch report states a crash with my app running on Pixel Android 8.0 (no issues with the others). When watching the replay, I see no issue and don't see the app crash.

This is the info provided.

Issue: Native crash of com.xxxxxxxxx

Can anyone point me in the right direction.

Answer 1

Android is open source, so when debugging something like this I always start with Google. A Google search for ' android source "cannot get a dirty matrix" ' leads here.

https://android.googlesource.com/platform/frameworks/base/+/master/libs/hwui/RenderProperties.h

Now this doesn't tell you how to fix it, but does tell you it is something wrong with the native rendering code with a device running Android O, using 64 bit native code.

If it was my app I'd try to find another Android Oreo device with an arm64 processor and see if it happens to me. But it is going to be hard to debug, and just as likely to be a bug with the OS or your game engine than something you can fix yourself (unless you have been writing native rendering code).

Answer 2

I stumbled upon this one as well (probably from a different cause). The error disappeared from the report after I downgraded the following libraries to:

com.google.firebase:firebase-perf:19.0.7 (downgrade from 19.0.8)
com.google.firebase:firebase-firestore-ktx:21.4.3 (downgrade from 21.50.0)
com.google.firebase:firebase-config-ktx:19.1.4 (downgrade from 19.2.0)

Didn't pinpoint the issue exactly but I'm guessing firebase-perf is to blame here.
