I'm receiving crash reports in Google Play Console for my app, and the stacktrace is as follows:
java.lang.UnsatisfiedLinkError: at mono.android.Runtime.register (Native Method) at md5f3dc63ecaad575af71bd7a9b1622f75b.n.<clinit> (n.java:20) at java.lang.Class.newInstance (Native Method) at android.app.ActivityThread.handleCreateBackupAgent (ActivityThread.java:3431) at android.app.ActivityThread.-wrap3 (Unknown Source) at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1813) at android.os.Handler.dispatchMessage (Handler.java:105) at android.os.Looper.loop (Looper.java:180) at android.app.ActivityThread.main (ActivityThread.java:6944) at java.lang.reflect.Method.invoke (Native Method) at com.android.internal.os.Zygote$MethodAndArgsCaller.run (Zygote.java:240) at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:835)
I'm using Xamarin.Android with Visual Studio for my development, and the app is targeting for Android Pie (API 28). The crash only happens for Android 8.0 and 8.1 devices (which are capable of arm64-v8a, not sure it's just a coincidence, most devices running Oreo are running in 64-bit anyways).
n in the stacktrace is my implementation of
BackupAgent. This happens once everyday or every 2 days, and it seems (not 100% sure yet) that Auto Backup is still running without problem with the error.
The problem has been around for almost a month, and I tried a couple of things but they don't seem to make any difference:
I also tried to remove my custom
BackupAgent class and make use of the default
BackupAgent, the problem was gone. I need to add extra logic in my
BackupAgent though, so this is a no-go for me.
Anyone having a similar problem? It would be nice if I could be guided with some clues to the problem. Thanks.
