Kotlin Coroutines codelab
"What you'll do" contains "Learn techniques to convert existing APIs to coroutines using suspendCoroutine.", but that is not mentioned anywhere in the codelab.
https://codelabs.developers.google.com/codelabs/kotlin-coroutines/index.html?index=..%2F..index#5 Review the existing code Open MainViewModelTest.kt in the androidTest folder. It should be test folder instead.
On the _Using coroutines with WorkManager_ page (12), _Testing our CoroutineWorker_ section, where the code sample specifies imports as well as code, there are 3 imports which are duplicated. ```...
In the **advanced-coroutines-codelab** sample, you've used `ConflatedBroadcastChannel` to watch the `growZone` change. https://github.com/googlecodelabs/kotlin-coroutines/blob/b71b981f8354a92fb3ebda37eceb7461e783d0bf/advanced-coroutines-codelab/finished_code/src/main/java/com/example/android/advancedcoroutines/PlantListViewModel.kt#L91-L103 I've used same technique in one of my side projects, and when resuming the listening activity, sometimes...
not "Open MainViewModelTest.kt in the androidTest folder. " but "Open MainViewModelTest.kt in the test folder. "
interface MainNetwork { `@GET("next_title.json")` `suspend fun fetchNextTitle(): Result` } I tried returning a `Result` & got `'kotlin.Result' can not be used as a return type`
At the end of 5th step there are example of **MainViewModel.kt**: ``` // resume in the main dispatcher // _snackbar.value can be called directly from main thread _taps.postValue("$tapCount taps") ```...
``` /** * Wait one second then update the tap count. */ private fun updateTaps() { // TODO: Convert updateTaps to use coroutines tapCount++ BACKGROUND.submit { Thread.sleep(1_000) _taps.postValue("$tapCount taps") }...
Wouldn't it be simpler to just use `LiveData.value` in the `com.example.android.kotlincoroutines.main.MainViewModelTest#whenMainClicked_updatesTaps` unit test? `getValueForTest()` seems a convoluted way to get to the same place. I understand it might be different...
