LazyWorker

LazyWorker is a helper class for doing tasks delayed. Such as checking inputs which require network operations and should not been done after each key down.

Setup (gradle based)

Edit your build.gradle and add this line to your dependencies:

implementation 'eu.rekisoft.android:lazyworker:2.0.4'

It should look something like this:

implementation {
    // other dependencies comes here
    implementation 'eu.rekisoft.android:lazyworker:2.0.4'
}

Example

Here is a sample for implementing a lifecycle aware countdown timer in Kotlin:

val countdown = LazyWorker.createLifeCycleAwareJob(viewLifecycleOwner.lifecycle) {
    val left = expiresAt - System.currentTimeMillis()
    val remaining = "%d:%02d".format(
        TimeUnit.MILLISECONDS.toMinutes(left),
        TimeUnit.MILLISECONDS.toSeconds(left % 60000)
    )
    println(remaining)
    if (expiresAt > System.currentTimeMillis()) {
        doLater(1000)
    } else {
        println("Time expired")
    }
}

// Start timer
countdown.doNow()
