Crash: No implementation found for void com.tns.AssetExtractor.extractAssets

[lambourn]

Environment

• CLI: 4.2.1
• Cross-platform modules: 4.2.0
• Android Runtime: 4.2.0

Describe the bug

We got several crash reports mostly occuring on Huawei devices running Android 9.0 where the app crashes on startup because of a missing AssetExtractor implementation (which seems pretty weird)

Any ideas what's happening there and how to resolve it?

@lambourn sorry for the late response. Do you still experience the same crashes. It's very odd as the method that cannot be found is part of the NativeScript.so library. Seems that the file exists as otherwise the crash would happen when trying to load the library here - https://github.com/NativeScript/android-runtime/blob/master/test-app/app/src/main/java/com/tns/RuntimeHelper.java#L70. So maybe the library is somehow corrupt which is quite strange because it happens only on some devices. Do you use ProGuard, Google Play app signing? Can you send us the apk so that we can see what we have there?
