Starting from 0.26.0 release we should define a scope for new coroutines (docs).
To avoid this boilerplate code I've created this small library that implements the most common CoroutineScopes used in Android apps.
Just extend your Activity/Fragment/ViewModel with the corresponding implementation.
// AppCompat scopes
class MyActivity : CoroutineScopedActivity()
class MyFragment : CoroutineScopedFragment()
class MyDialogFragment : CoroutineScopedDialogFragment()
// ViewModel scopes
class MyViewModel : CoroutineScopedViewModel()
class MyAndroidViewModel(app: Application) : CoroutineScopedAndroidViewModel(app)class MainActivity : CoroutineScopedActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
// Don't use launch(UI), it's deprecated now
launch {
Log.d(TAG, "MAIN THREAD")
withContext(Dispatchers.Default){
Log.d(TAG, "OTHER THREAD")
}
}
}
}// Add JitPack to your repositories if needed
repositories {
maven { url 'https://jitpack.io' }
}
// AppCompat scopes
implementation 'com.github.adrielcafe.androidcoroutinescopes:appcompat:1.0.1'
// ViewModel scopes
implementation 'com.github.adrielcafe.androidcoroutinescopes:viewmodel:1.0.1'
