I'm trying to start a service from a fragment but my code doesn't seem to run properly or I think there is something wrong with how I deal with contexts. It runs ok when I start my service from inside an activity but it doesn't work inside a fragment.
This is my fragment class:
class OnAirFragment : BaseFragment() {
private var play = "Play"
private var playValue = false
private lateinit var updatePlaybackUI: BroadcastReceiver
private var playWhenReady = "Play State"
private var playbackState = "Playback State"
private var isClicked = false
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View? {
// Inflate the layout for this fragment
val view = inflater.inflate(R.layout.fragment_on_air, container, false)
view.start.setOnClickListener {
Log.d("TEST", "TAP")
if (!isClicked) {
Log.d("TEST2", "TAP2")
start.setBackgroundResource(R.drawable.ic_pause_empty)
val intent = Intent(context, PlaybackService::class.java)
intent.putExtra(play, playValue)
Util.startForegroundService(context, intent)
var intentToService = Intent("activity.to.service.transfer")
intentToService.putExtra("x", true)
context!!.sendBroadcast(intentToService)
val filter = IntentFilter()
filter.addAction("service.to.activity.transfer")
updatePlaybackUI = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent?) {
// UI update here
var playPauseState = intent!!.getBooleanExtra(playWhenReady, true)
var stopState = intent.getIntExtra(playbackState, Int.MAX_VALUE)
if (!playPauseState || stopState == 1) {
start.setBackgroundResource(R.drawable.ic_play_empty)
isClicked = false
} else {
start.setBackgroundResource(R.drawable.ic_pause_empty)
}
}
}
context!!.registerReceiver(updatePlaybackUI, filter)
isClicked = !isClicked
} else {
Log.d("TEST3", "TAP3")
playValue = false
start.setBackgroundResource(R.drawable.ic_play_empty)
val intent = Intent(context, PlaybackService::class.java)
intent.putExtra(play, playValue)
context!!.stopService(intent)
isClicked = !isClicked
}
}
return view
}
}
And this is my service class:
class PlaybackService : Service() {
private var player: SimpleExoPlayer? = null
private var playerNotificationManager: PlayerNotificationManager? = null
private var mediaSession: MediaSessionCompat? = null
private lateinit var receiver: BroadcastReceiver
private var playWhenReady = "Play State"
private var playbackState = "Playback State"
override fun onCreate() {
super.onCreate()
val context = this
player = ExoPlayerFactory.newSimpleInstance(context, DefaultTrackSelector())
val dataSourceFactory = DefaultDataSourceFactory(
context, Util.getUserAgent(context, "Exo"))
val mediaUri = Uri.parse("http://www.radioideal.net:8026/;")
val mediaSource = ExtractorMediaSource.Factory(dataSourceFactory)
.createMediaSource(mediaUri)
player!!.prepare(mediaSource)
player!!.playWhenReady = true
val filter = IntentFilter()
filter.addAction("activity.to.service.transfer")
receiver = object : BroadcastReceiver() {
override fun onReceive(context: Context, intent: Intent?) {
var play = intent!!.getBooleanExtra("x", true)
player!!.playWhenReady = play
}
}
registerReceiver(receiver, filter)
player?.addListener(eventListener)
playerNotificationManager = PlayerNotificationManager.createWithNotificationChannel(
context,
"BREAKFAST RADIO",
R.string.exo_download_notification_channel_name,
1000,
object : PlayerNotificationManager.MediaDescriptionAdapter {
override fun getCurrentContentTitle(player: Player): String {
return "BR Live"
}
@Nullable
override fun createCurrentContentIntent(player: Player): PendingIntent? {
return null
}
@Nullable
override fun getCurrentContentText(player: Player): String? {
return "BR Live"
}
@Nullable
override fun getCurrentLargeIcon(player: Player, callback: PlayerNotificationManager.BitmapCallback): Bitmap? {
return BitmapFactory.decodeResource(context.resources, R.drawable.exo_controls_play)
}
}
)
playerNotificationManager!!.setNotificationListener(object : PlayerNotificationManager.NotificationListener {
override fun onNotificationStarted(notificationId: Int, notification: Notification) {
startForeground(notificationId, notification)
}
override fun onNotificationCancelled(notificationId: Int) {
stopSelf()
}
})
playerNotificationManager!!.setPlayer(player)
playerNotificationManager?.setFastForwardIncrementMs(0)
playerNotificationManager?.setRewindIncrementMs(0)
playerNotificationManager?.setUseNavigationActions(false)
val playbackStateBuilder = PlaybackStateCompat.Builder()
playbackStateBuilder.setActions(PlaybackStateCompat.ACTION_PLAY or PlaybackStateCompat.ACTION_PAUSE)
mediaSession = MediaSessionCompat(context, "BREAKFAST")
mediaSession!!.isActive = true
mediaSession?.setPlaybackState(playbackStateBuilder.build())
playerNotificationManager!!.setMediaSessionToken(mediaSession!!.sessionToken)
}
override fun onDestroy() {
mediaSession!!.release()
playerNotificationManager!!.setPlayer(null)
player!!.release()
player = null
super.onDestroy()
}
@Nullable
override fun onBind(intent: Intent): IBinder? {
return null
}
override fun onStartCommand(intent: Intent, flags: Int, startId: Int): Int {
return Service.START_STICKY
}
private var eventListener: Player.EventListener = object : Player.EventListener {
override fun onPlaybackParametersChanged(playbackParameters: PlaybackParameters?) {
var i = 0
}
override fun onSeekProcessed() {
var i = 0
}
override fun onTracksChanged(trackGroups: TrackGroupArray?, trackSelections: TrackSelectionArray?) {
var i = 0
}
override fun onPlayerError(error: ExoPlaybackException?) {
var i = 0
}
override fun onLoadingChanged(isLoading: Boolean) {
var i = 0
}
override fun onPositionDiscontinuity(reason: Int) {
var i = 0
}
override fun onRepeatModeChanged(repeatMode: Int) {
var i = 0
}
override fun onShuffleModeEnabledChanged(shuffleModeEnabled: Boolean) {
var i = 0
}
override fun onTimelineChanged(timeline: Timeline?, manifest: Any?, reason: Int) {
var i = 0
}
override fun onPlayerStateChanged(playWhenReady: Boolean, playbackState: Int) {
sendPlaybackState(playWhenReady, playbackState)
}
}
private fun sendPlaybackState(playWhenReadyValue: Boolean, playbackStateValue: Int) {
var intent = Intent("service.to.activity.transfer")
intent.putExtra(playWhenReady, playWhenReadyValue)
intent.putExtra(playbackState, playbackStateValue)
sendBroadcast(intent)
}
}
and I'm not sure my broadcast receivers work either.
Register Service in Manifest.xml
