⏳️ Light library to use Timer in Android. The library is implemented via Kotlin Coroutines and Kotlin Flows.
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
maven { url 'https://jitpack.io' }
}
}
Include below dependency in build.gradle of application and sync it:
implementation 'com.github.raheemadamboev:timer-flow:1.0.2'
Create an object of Timer:
val timer = Timer()
Set timer duration in milliseconds (default: 10 000):
timer.timerDuration = 5_000L
Start timer:
timer.start()
Observe time of timer:
lifecycleScope.launch {
timer.time.collectLatest { time ->
// update UI, do something
println(time.toString())
}
}
Pause timer:
timer.pause()
If you pause timer, do not forget to stop() it. Otherwise, it runs forever.
Resume timer:
timer.resume()
Reset timer:
timer.reset()
Set checkpoint time (default: 3 000) that you will get notified when it is reached. It is implemented via Kotlin Channel and received as Kotlin Flow. So you will only get notified once:
timer.timerCheckpoint = 2_500L
lifecycleScope.launch {
timer.event.collectLatest { event ->
when(event) {
Started -> Unit // timer started
Checkpoint -> Unit // checkpoint reached
Finished -> Unit // timer finished naturally, not programmatically
}
}
}
Observe timer states. It is implemented via Kotlin StateFlow so you always get the current timer state:
lifecycleScope.launch {
timer.state.collectLatest { state ->
when(state) {
Idle -> Unit // timer is in idle position, not running
Ticking -> Unit // timer is ticking, running
Paused -> Unit // timer is paused, not running
Finished -> Unit // timer is finished naturally, not programmatically finished, not running
Stopped -> Unit // timer is stoped programmatically by calling stop() function, not running
}
}
}
After finished using Timer, please do not forget to stop(). Otherwise, it won't get garbage collected!
timer.stop()
