[elizarov]

When and how it reproduces? Does it reproduce under emulator? Under what Android version?

[xiaozhilaoliu]

@elizarov thanks ! it reproduce under in real device,Android verion is 5.1.1,

Seeing the same on Android 5.0, 5.0.1 and 5.0.2

[haitech]

We are seeing the same problem on firebase and on our test-devices.
minSdkVersion 21
targetSdkVersion 28
kotlinVersion 1.3.20
kotlinCoroutine 1.1.0

This is only affecting Android 5.x devices, and it's possible to reproduce it on Android Emulator.

open class ScopedViewModel : ViewModel(), CoroutineScope {
    override val coroutineContext = Dispatchers.Main + Job()
    ...
}

class CrashhViewModel constructor() : ScopedViewModel() {
    fun crash() {
        launch {
        // This will crash
        }
    }
}

For some reason Samsung devices is not affected by this.

We also experience the same issue on Xiaomi Redmi Note 2 (5.0.2), P8 Lite (5.0.1), LenovoTAB2 A7-30DC (5.0.1), Lenovo A6010 (5.0.2) with:

• kotlin 1.3.21,
• coroutines 1.1.1,
• release build with Proguard obfuscation

Unfortunately, don't have access to such device yet and can't reproduce locally...

Should be fixed in 1.3.3
