Foreword In the previous article, we introduced in detail three commonly used keywords in Kotlin: inline, noinline, and crossinline. In this article, the author intends to combine the introductions in the previous articles to explain our application in actual development. Usually extension functions and higher-order functions are used in combination, which can simplify the code […]

Kotlin + Coroutine + Room used together
Article directory Preface Integrated Room Combined with the use of coroutines Summarize 1. Foreword, Now that kotlin is the trend, coroutines must be used, and with the development of jetpack, many useful libraries have been brought. For example, Room was mentioned today, which is a database similar to greenDao. It not only supports kotlin coroutines/RxJava, […]

Kotlin coroutine explores again why using coroutine is slower?
Foreword A few months ago, I wrote an article about concurrency issues in Kotlin coroutines: I obviously used mutex to lock, why didn’t it work? , tells the process of discovering something inappropriate in the Koltin coroutine written by a colleague when debugging a certain problem, which eventually led to a BUG. After a few […]

Monitoring network status changes — combining registerNetworkCallback and broadcast (kotlin)
illustrate Android Android monitors network status changes. In applications, we generally need to monitor changes in device network status and make corresponding business processing. We need a convenient and global monitoring implementation. . Use different API methods for different device system versions; Pay attention to the adaptation problem of using broadcast to monitor network status […]
The use of kotlin coroutines in Android
kotlin coroutine in Android Coroutines are a concurrency design pattern that can be used on the Android platform to simplify code that executes asynchronously On Android, coroutines help manage long-running tasks that, if not managed properly, can block the main thread and make your app unresponsive. Features: Lightweight Thread: Sub-threads are independent from the main […]
Coroutine in Kotlin – directly test the coroutine
In this exercise, you will write a test that calls the suspend function directly. Since refreshTitle is provided as a public API, the system will test it directly, showing how to call the coroutine from the test. Here is the refreshTitle function you implemented in the previous exercise: TitleRepository.kt suspend fun refreshTitle() {<!– –> try […]
