Exo player add raise/send analytics event total time spent

Question

I Want to add analytics events to exo player need following data

total time spent on video
total play time
total pause time
how many time paused

How this can be done
Tried following callbacks but not able to find exact solution to this
Player.EventListener

or I need to use AnalyticsListener?
Update on this found that exo player library version 2.12.0 has included PlaybackStatsListener which gives most of required analytics data but data is not accurate
playbackStatsListener.playbackStats.totalPlayTimeMs
playbackStatsListener.playbackStats.totalPausedTimeMs

these two fields are not showing accurate or reliable values.

private var mPlayTime = 0L
private var mPlayTotalTime = 0L

override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
    if (playbackState == 3) {
        if (playWhenReady) {
            mPlayTime = System.currentTimeMillis()
        } else {
            if (mPlayTime.toInt() != 0) {
                val mPauseTime = System.currentTimeMillis() - mPlayTime
                mPlayTotalTime += mPauseTime
                mPlayTime = 0
            }
        }
    } else {
        if (mPlayTime.toInt() != 0) {
            val mPauseTime = System.currentTimeMillis() - mPlayTime
            mPlayTotalTime += mPauseTime
            mPlayTime = 0
        }
    }
    val mTotalDurationInSec = (mPlayTotalTime / 1000) % 60
}

Here is a tested piece of code on how you could use the AnalyticsListener with onIsPlayingChanged to achieve this
private var playTime = 0L // in ms
private var pauseTime = 0L // in ms
private var totalTime = 0L // in ms
private var pressedPaused = 0

private val analyticsListener: AnalyticsListener = object : AnalyticsListener {
    private var initTime = 0L

override fun onIsPlayingChanged(eventTime: AnalyticsListener.EventTime, isPlaying: Boolean) {
        if(isPlaying) {
            if(initTime != 0L) pauseTime += System.currentTimeMillis() - initTime
            initTime = System.currentTimeMillis()
        } else {
            if(initTime != 0L) playTime += System.currentTimeMillis() - initTime
            initTime = System.currentTimeMillis()
            pressedPaused++
        }
        totalTime = playTime+pauseTime
        Log.e("onIsPlaying", "PLAYTIME: $playTime")
        Log.e("onIsPlaying", "PRESSEDPAUSE: $pressedPaused")
        Log.e("onIsPlaying", "PAUSETIME: $pauseTime")
        Log.e("onIsPlaying", "TOTALTIME: $totalTime")
        super.onIsPlayingChanged(eventTime, isPlaying)
    }
}
