Run the starter app now and you will see the following:īecause this is an offline-first Android app, when the app loads for the first time, it tries to load data from the local database first. If you have already downloaded the starter project, then import it into Android Studio. Once fetched, the data is saved to the local database using the Room architecture components library. You can access the documentation for the same at. There is a repository that takes care of fetching data from the SWAPI API, which is a public Star Wars API. As you already know, the app is an offline first MVP app. Without much ado, jump over to the next section in this chapter.Ĭoroutines on Android: Part 3 Getting startedįor this chapter, you will start from where you left off in the last chapter, with the Android app called StarSync. Thankfully, there are ways to handle those and the tooling/libraries are built to address such situations.Īll of this and more will be covered in this chapter while working with an Android app. Now, imagine trying to debug a codebase wherein hundreds of these coroutines are executing. It gets fairly more complex when coroutines are added to the system.Īs you know by now, there could be hundreds of coroutines, and they can be executed easily because they are very lightweight. More importantly, it is the best practice to be able to test the business logic of complex asynchronous tasks. It is not immediately clear on what thread the code is executing, and trying to figure it out usually involves adding logging statements and debugging the code flow. 12.1 Getting started with broadcast channelsĭeveloping Android apps can get complex when dealing with asynchronous tasks.10.5 Yield and YieldAll at your service.Locked Building Sequences & Iterators with Yield.Section II: Channels & Flows Section 2: 6 chapters Show chapters Hide chapters Locked Setting Up Your Build Environments.1.9 Explaining coroutines: The inner works.
