Hi all, I am using the following scope to launch the coroutine on button click. But the app crashes w/o any logs. Do you know what I am missing?

private val scope = CoroutineScope(Dispatchers.Main + SupervisorJob())
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)

    presenter = ProductPresenter(ProductRepository(Network(), Database()), scope)

    button_fetch.setOnClickListener {
        presenter.onFetchClick()
    }
}

---------------------------------------------------------------------

    fun onFetchClick() {
        loadingState.value = true

        scope.launch {
            //...
        }
    }

You can try logging the error manually from a custom Thread.UncaughtExceptionHandler that you set in the onCreate method of your Application class (that you need to register in the manifest). I encountered such issues in the past where crash cause didn't show and that's how I worked around it until I saw double logs again.

When I use GlobalScope it's working fine

Looks like i didn't include kotlinx-coroutines-android dependency. That caused the uncaught exception 🙂 .
A lint warning would have saved time. Thanks @louiscad

You can submit a feature request on kotl.in/issue so an inspection is added for android modules that have a dependency on kotlinx.coroutines-core but not on the android artifact.
