Android Basics: Load and display images from the Internet, parameters of bindStatus() problem #173

Closed ommos61 closed 8 months ago

ommos61 commented 1 year ago

name: Android Basics Unit 4 issue about: Report problems with the Android Basics Unit 4 codelabs title: 'Android Basics Unit 4 issue: parameters of bindStatus() problem' labels: '' assignees: ''

URL of codelab https://developer.android.com/codelabs/basic-android-kotlin-training-internet-images#4

In which task and step of the codelab can this issue be found? Add a binding adapter for the status ImageView, step 1

Describe the problem The codelabs page describes to use a nullable MarsApiStatus in the parameter list (like 'status: MarsApiStatus?'). This causes a problem in the 'when' statement, because the 'null' case is not handled. The code on github doesn't have the nullable modifier, so leave it out in the codelabs page too.
