CountDownTimer-With-Pause-Resume-Android-Kotlin

CountDownTimer in Android is used to set a countdown based on interval set by you and it will stop when the time has come in future. You can use this Count Down Timer for creating any countdown for an event. But in some cases we need Pause or Resume CountDownTimer but it doesn't have Pause and Resume methods. SonicCountDownTimer library will fulfill this need.

Add Gradle Files

Add maven repository in project level build.gradle or in latest project setting.gradle file

repositories {
    google()
    mavenCentral()
    maven { url 'https://jitpack.io' }
}

Add following dependency in app gradle file

  implementation 'com.github.orbitalsonic:SonicCountDownTimer:1.0.5'
 

Java or Kotlin

Three constructors for initializing

    SonicCountDownTimer()       //default time interval is 1 second
    SonicCountDownTimer(timeInMillis: Long)   //default time interval is 1 second 
    SonicCountDownTimer(timeInMillis: Long, intervalInMillis: Long)

Methods to manage countdown timer

    fun startCountDownTimer()
    fun pauseCountDownTimer()
    fun resumeCountDownTimer()
    fun stopCountDownTimer()
    fun cancelCountDownTimer()

Abstract methods for updating UI

    fun onTimerTick(timeRemaining: Long)    // Called after every time interval.
    fun onTimerFinish()                   // Called when time specified finishes 

Setters & Getters

    fun setCountDownTime(timeInMillis: Long)
    fun setTimeInterval(intervalInMillis: Long)
    fun getRemainingTime(): Long

Example

       val  sonicCountDownTimer =
        object : SonicCountDownTimer(30000, 1000) {

            override fun onTimerTick(timeRemaining: Long) {
                // Update UI

            }

            override fun onTimerFinish() {
                // CountDownTimer finished

            }

        }

    sonicCountDownTimer.startCountDownTimer()
