We can then combine the results from both to display a combined result. I tried changing the delay when registering the sensor to fastest, game, normal, and I even tried to set the delay to 0 but nothing worked. I also tried the step detector sensor but had the same results. We can use async coroutine builder to call multiple pieces of asynchronous code in parallel. The problem is that the counter always misses the first few steps i am using the step counter sensor introduced in android kitkat 4.4. Now, coming to the best part about using Kotlin Coroutines with async. Once calculateSum() returns a value, the suspended coroutine will resume and print the calculated result. The execution of other tasks (print statement) continues. While calculateSum() is executing, the following happens:Īsync builder will suspend the coroutine (used for calculating sum). Println("Carry on with some other task while the coroutine is waiting for a result.")ĭelay(3000L) // keeping jvm alive till calculateSum is finishedĭelay(2000L) // simulate long running taskĪsync will return a Deferred value as the result of calculateSums() by calling the suspending function await() on it.Īwait() will fetch us the result that calculateSum()/ async returns. On Android Plus devices it is possible to specify a /delay parameter (in seconds): reset /S. It is also worthwhile to note that suspending functions are not asynchronous themselves.Ī suspending function can be written by adding a prefix to a function with the keyword “suspend” like so: suspend fun doSomething() : String ") ![]() The suspending feature of these functions helps us to write asynchronous code in a synchronous manner. Suspending functions are functions that have the ability to suspend the execution of current coroutine without blocking the current thread. These functions can resume execution at some point. Kotlin Coroutine Builders in AndroidĬoroutines are light-weight threads that do not block the main thread while providing the ability to call suspending functions on the main thread. Kotlin Coroutines make writing asynchronous and non-blocking code easy to read and understand by eliminating the need to handle traditional callback pattern. Kotlin Coroutines came as a boon to me after struggling with asynchronous programming over 4 years of my career as an android developer. GlobalScope in coroutines and why to avoid it.
