Kotlin Coroutines on Android

Some examples of how Coroutines can be used on Android in an app built using MVVM architecture. The examples that illustrate error handling randomly throw an Exception that gets caught and displayed by a Snackbar.

Branches

• RxJava: Load Github repos using Retrofit
• Coroutines using CoroutineScope: Load Github repos using CoroutineScope and Retrofit
• Coroutines using viewModelScope: Load Github repos using viewModelScope and Retrofit
• Coroutines making sync calls: Load two images over the network synchronously
• Coroutines using async/await: Load two images over the network asynchronously
• Coroutines using CoroutineExceptionHandler: Load two images over the network synchronously and handle exceptions using custom CoroutineExceptionHandler
• Coroutines using try/catch: Load two images synchronously over the network and handle exceptions using try/catch
• Coroutines using async and try/catch: Load two images asynchronously over the network and handle exceptions using try/catch if any of the images fail to load. First image to fail will cancel its parent job which will cancel the rest of its children (in this case, the other image loading).
