In my app I displayed a notification with a foreground service, which is in charge of playing music. The notification is handled by
com.google.android.exoplayer2.ui.PlayerNotificationManager
android.support.v4.media.session.MediaSessionCompat
com.google.android.exoplayer2.ext.mediasession.MediaSessionConnector
mediaSession = MediaSessionCompat(this, "Player", null, null)
mediaSession.isActive = true
mediaSessionConnector = MediaSessionConnector(mediaSession)
mediaSessionConnector.setPlayer(exoPlayer)
playerNotificationManager = PlayerNotificationManager.createWithNotificationChannel(
this,
"notification_channel_player",
R.string.notification_channel_name_player,
0,
PLAYER_NOTIFICATION_ID,
object : PlayerNotificationManager.MediaDescriptionAdapter {
override fun createCurrentContentIntent(player: Player?): PendingIntent? {
// intent
}
override fun getCurrentLargeIcon(player: Player?, callback: PlayerNotificationManager.BitmapCallback?): Bitmap? {
// large icon
}
override fun getCurrentContentText(player: Player?): String? {
// artist
}
override fun getCurrentContentTitle(player: Player?): String {
// title
}
},
object : NotificationListener {
override fun onNotificationPosted(notificationId: Int, notification: Notification?, ongoing: Boolean) {
startForeground(notificationId, notification)
}
})
playerNotificationManager.setSmallIcon(R.drawable.ic_notification)
// has previous and next
playerNotificationManager.setUseNavigationActions(true)
playerNotificationManager.setUseNavigationActionsInCompactView(true)
// no fast-forward and rewind
playerNotificationManager.setFastForwardIncrementMs(0)
playerNotificationManager.setRewindIncrementMs(0)
// no stop
playerNotificationManager.setUseStopAction(false)
playerNotificationManager.setMediaSessionToken(mediaSession.sessionToken)
playerNotificationManager.setPlayer(exoPlayer)
When the screen is on, there is no problem displaying the content title and text. But when I lock screen and in AOD mode, on my Pixel 3 I see a "No title" displayed. But if I use Apple Music, it displays the title and artists very well.
My app :
Apple music:
My question is, how can I configure this title and text based on my current implementation? Thanks.
I just answer my own question because I have found and solved the problem.
I have only set the notification's media description adapter, but in fact, the media session needs to set metadata too.
Since we are using mediaSessionConnector, it can be setup by passing a QueueNavigator to the mediaSessionConnector, so we can use the player instance and window index to build current media's metadata. e.x:
val timelineQueueNavigator = object : TimelineQueueNavigator(mediaSession) {
override fun getMediaDescription(player: Player?, windowIndex: Int): MediaDescriptionCompat {
player?.let { safePlayer ->
return MediaDescriptionCompat.Builder().apply {
setTitle("......")
setSubtitle("......")
}.build()
}
return MediaDescriptionCompat.Builder().build()
}
}
mediaSessionConnector.setQueueNavigator(timelineQueueNavigator)
Another point is, by default the mediaSessionConnector use MediaSessionConnector.DefaultMediaMetadataProvider. It doesn't setup METADATA_KEY_ARTIST which will be used in AOD mode as the artist. So I have created my own MediaMetadataProvider, adding METADATA_KEY_ARTIST.
if (description.subtitle != null) {
val subTitle = description.subtitle.toString()
builder.putString(MediaMetadataCompat.METADATA_KEY_ARTIST, subTitle)
builder.putString(MediaMetadataCompat.METADATA_KEY_DISPLAY_SUBTITLE, subTitle)
}
Here I used METADATA_KEY_TITLE and METADATA_KEY_ARTIST for title and the description:
MediaMetaData data = PlayerManager.getInstance().getCurrentMediaMetaData();
Bitmap bitmap = ((BitmapDrawable) AppController.getInstance().getResources().getDrawable(R.drawable.app_logo)).getBitmap();
Bundle extras = new Bundle();
extras.putString(MediaMetadataCompat.METADATA_KEY_TITLE,data.getMediaTitle());
extras.putString(MediaMetadataCompat.METADATA_KEY_ARTIST, data.getMediaAlbum());
return new MediaDescriptionCompat.Builder()
.setIconBitmap(bitmap)
.setExtras(extras)
.build();
You may have to build the notification like this:
Notification.Builder(context, channel).setContentTitle("Title").setContentText("Description").build()
Please, add your code here. It will be easier to help.
EDIT:
You are not returning the title at the adapter:
override fun getCurrentContentTitle(player: Player?): String = "Add the title here"

I am trying to download a video for offline in exoplayer, I want to show downloading progress inside an activity.
How can I bind to the DownloadService in exoplayer. so that I can update the current downloading progress in an activity? I try to override onBind method but there is no onBind method.
DownloadService
class MediaDownloadService : DownloadService(
C.DOWNLOAD_NOTIFICATION_ID, 1000,
C.CHANNEL_ID, R.string.channel_name, R.string.channel_description
) {
private lateinit var downloadManager: DownloadManager
override fun onCreate() {
downloadManager = DownloadUtil.getDownloadManager(this)
downloadManager.addListener(object : DownloadManager.Listener {
override fun onDownloadChanged(downloadManager: DownloadManager, download: Download) {
if (download.bytesDownloaded == download.contentLength) {
toast("Download Completed!")
}
debug(download.failureReason)
}
})
super.onCreate()
}
override fun getDownloadManager(): DownloadManager {
return downloadManager
}
override fun getForegroundNotification(downloads: MutableList<Download>): Notification {
val intent = Intent(this, MainActivity::class.java)
val pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationHelper = DownloadNotificationHelper(this, C.CHANNEL_ID)
return notificationHelper.buildProgressNotification(
R.drawable.ic_notification,
pendingIntent,
"simple message",
downloads
)
}
override fun getScheduler(): Scheduler? {
return null
}
inner class DownloadBinder: Binder() {
val service: MediaDownloadService
get() = this#MediaDownloadService
}
}
To show the current download progress in an activity
You need to override and listen to the DownloadTracker.Listener which will enable you to know the different state of your download.
When the state is at Download.STATE_DOWNLOADING start a coroutine/flow to send the current value of the download to your activity.
I have used this flow (which send every 1 second the value of the percentDownload of the download you'd like)
val downloadManager: DownloadManager // is set before in my object
suspend fun getCurrentProgressDownload(uri: Uri?): Flow<Float?> {
var percent: Float? = downloadManager.currentDownloads.find { it.request.uri == uri }?.percentDownloaded
return callbackFlow {
while(percent != null) {
percent = downloadManager.currentDownloads.find { it.request.uri == uri }?.percentDownloaded
offer(percent)
withContext(Dispatchers.IO) {
delay(1000)
}
}
}
}
Display it the way you like
I have created a repository where you can see download progress in the activity, This is merely an example that could use some optimisation.

if some thing are not clear don't hesitate to ask
I am using Exoplayer to create my own music player. I am also adding the option to download the track but I have a problem when I am trying to download the track that I am playing. I add a notification to the download to check the progress of the download and it appears but it even doesn't start. What I think is that it might have some kind of problem with the buffering cache and the download since they are stored in the same folder.
To download the tracks I do the following:
override fun addDownloadTrack(track: Track) {
getIfTrackIsCached.run({ isCached ->
if (!isCached) {
val data = Util.toByteArray(track.title.byteInputStream())
val downloadRequest =
DownloadRequest(track.id, DownloadRequest.TYPE_PROGRESSIVE, Uri.parse(track.href), Collections.emptyList(), track.id, data)
DownloadService.sendAddDownload(context, ExoPlayerDownloadService::class.java, downloadRequest, false)
}
}, ::onError, GetIfTrackIsCached.Params(track.id))
}
This is the DownloadService:
class ExoPlayerDownloadService : DownloadService(
FOREGROUND_NOTIFICATION_ID,
DEFAULT_FOREGROUND_NOTIFICATION_UPDATE_INTERVAL,
Constants.CHANNEL_DOWNLOAD_ID,
R.string.exo_download_notification_channel_name) {
private val manager: DownloadManager by inject()
private val channelIsCached: ChannelPublisher<CachedMedia> by inject(PUBLISHER_IS_CACHED)
private val notificationHelper: DownloadNotificationHelper by inject()
private var nextNotificationId: Int = FOREGROUND_NOTIFICATION_ID
override fun onCreate() {
super.onCreate()
if (!manager.isInitialized) {
manager.maxParallelDownloads = MAX_PARALLEL_DOWNLOADS
}
}
override fun getDownloadManager(): DownloadManager = manager
override fun getForegroundNotification(downloads: MutableList<Download>?): Notification {
var text = ""
var index = 1
downloads?.forEach { text += "${if (downloads.size > 1) "${index++} - " else ""}${Util.fromUtf8Bytes(it.request.data)}\n" }
return notificationHelper.buildProgressNotification(R.drawable.ic_stat_downloading, null, text, downloads)
}
override fun getScheduler(): Scheduler? = null
override fun onDownloadChanged(download: Download?) {
val notification = when (download?.state) {
Download.STATE_COMPLETED -> {
channelIsCached.publish(CachedMedia(download.request.id, true))
notificationHelper.buildDownloadCompletedNotification(R.drawable.ic_stat_download_complete, null, Util.fromUtf8Bytes(download.request.data))
}
Download.STATE_FAILED ->
notificationHelper.buildDownloadFailedNotification(R.drawable.ic_stat_download_failed, null, Util.fromUtf8Bytes(download.request.data))
else -> null
}
notification?.let { NotificationUtil.setNotification(this#ExoPlayerDownloadService, ++nextNotificationId, it) }
}
companion object {
private const val MAX_PARALLEL_DOWNLOADS = 3
private const val FOREGROUND_NOTIFICATION_ID = 2000
}
}
And to create the cache I use this:
SimpleCache(File(androidContext().cacheDir, CACHE_MEDIA_FOLDER), NoOpCacheEvictor(), get<DatabaseProvider>())
How can I avoid conflicts between buffering cache and downloaded files?
I had this issue also, and found the solution!
The downloading documentation states
The CacheDataSource.Factory should be configured as read-only to avoid downloading that content as well during playback.
To do this you must call setCacheWriteDataSinkFactory(null) on your CacheDataSource.Factory object.
This will prevent the stream from writing to the cache, allowing the downloader to write as expected.
I am using interactive video broadcasting in my app.
I am attaching class in which I am using live streaming.
I am getting the audio issue when I go back from the live streaming screen to the previous screen. I still listen to the audio of the host.
previously I was using leave channel method and destroying rtc client object, but after implementing this when I go back from streaming class then it closes all users screen who are using this app because of leave channel method. after that, I removed this option from my on destroy method.
Now I am using disable audio method which disables the audio but when I open live streaming class it doesn't enable audio. Enable audio method is not working I also used the mute audio local stream method and rtc handler on user mute audio method.
I am getting error--
"LiveStreamingActivity has leaked IntentReceiver io.agora.rtc.internal.AudioRoutingController$HeadsetBroadcastReceiver#101a7a7
that was originally registered here. Are you missing a call to
unregisterReceiver()? android.app.IntentReceiverLeaked: Activity

Receiver is registering in SDK and exception is coming inside the SDK that is jar file I can't edit.

I think first you want to put setupRemoteVideo in onFirstRemoteVideoDecoded callback instead of the onUserJoined callback. Also, in the onDestroy callback, you should call RtcEngine.destroy() instead of RtcEngine.destroy(mRtcEngine).
I try to cast youtube video from my android app to chromecast or smart tv through miracast.
But I can cast only source url for video like https://media.w3.org/2010/05/sintel/trailer.mp4
How can I cast web page with youtube or vimeo url video?
I know that YouTube app can cast video to some smart tv without chromecast and it looks like YouTube TV page. For example here https://www.youtube.com/watch?v=x5ImUYDjocY
I try to use Presentation API to set WebView in it:
#TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)

val wv = WebView(context)
wv.settings.javaScriptEnabled = true
wv.webChromeClient = WebChromeClient()
wv.loadUrl("https://www.youtube.com/watch?v=DxGLn_Cu5l0")
setContentView(wv)
super.onCreate(savedInstanceState)
}

New to Android development and I’m trying out the latest addHistoricMessage, and I’m missing something because it’s not displaying anything. On rare occasion the addMessage text is displayed, but the addHistoricMessage is never displayed. addMessage works consistently when using NotificationCompat, but NotificationCompat doesn’t appear to have addHistoricMessage.
Any thoughts appreciated - using androidx.appcompat:appcompat:1.0.2 and compileSdkVersion and targetSdkVersion are both 28.
An example of what I’m seeing is:
Test button that calls notification:
fun test(view: View) {
val job = GlobalScope.launch {
val repository = DataRepository.getInstance(Db.getDb(this#MainActivity))
AlarmReceiver().notifyTest(
this#MainActivity,
repository.upcomingDetail(9),
arrayListOf("Hi!", "Miss you!", "Hello!")
)
}
}
Notification methods and related (less important code removed):
fun notifyTest(context: Context, upcoming: UpcomingDetail, top3Sent: List<String>?) {
//...
#TargetApi(Build.VERSION_CODES.P)
when (Build.VERSION.SDK_INT) {
in 1..27 -> {
with(NotificationManagerCompat.from(context)) {
notify(upcoming.id.toInt(), legacyNotificationBuilder(
context,
upcoming,
noteIntent,
contentPending,
disablePending,
deletePending,
postponePending,
top3Sent
).build())
}
}
else -> context.getSystemService(NotificationManager::class.java)
.notify(upcoming.id.toInt(), notificationBuilder(
context,
upcoming,
noteIntent,
contentPending,
disablePending,
deletePending,
postponePending,
top3Sent
).build())
}
}
#RequiresApi(Build.VERSION_CODES.P)
private fun notificationBuilder(
context: Context,
upcoming: UpcomingDetail,
noteIntent: Intent,
contentPending: PendingIntent,
deletePending: PendingIntent,
disablePending: PendingIntent,
postponePending: PendingIntent,
top3Sent: List<String>?
): Notification.Builder {
val recipient: android.app.Person = android.app.Person.Builder().setName("Darren").setImportant(true).build()
val you: android.app.Person? = null
val messageStyle = Notification.MessagingStyle(recipient)
val message1 = Notification.MessagingStyle.Message("Hello!", Instant.now().minusSeconds(10 * 60).toEpochMilli(), recipient)
messageStyle.addHistoricMessage(message1)
messageStyle.addMessage(Notification.MessagingStyle.Message("Hi", Instant.now().toEpochMilli(), recipient))
val remoteInput: android.app.RemoteInput = android.app.RemoteInput.Builder(upcoming.id.toString()).run {
top3Sent?.let { setChoices(top3Sent.toTypedArray()) }
build()
}
//...
val inputAction = Notification.Action.Builder(0, context.getString(R.string.button_edit), inputPending).run {
addRemoteInput(remoteInput)
build()
}
return Notification.Builder(context, "Input").apply {
setSmallIcon(R.drawable.ic_stat)
style = messageStyle
setAutoCancel(true)
setCategory(Notification.CATEGORY_REMINDER)
setColor(ContextCompat.getColor(context, R.color.secondaryDarkColor))
setContentIntent(contentPending)
setDeleteIntent(deletePending)
setGroup("notifications")
setOnlyAlertOnce(true)
setVisibility(Notification.VISIBILITY_PRIVATE)
addAction(inputAction)
}
}
This is the behavior of historic message
Historic message is not normally shown at the notification. It is a special message that is only shown when user is replying through a RemoteInput. See the image above to see the behaviour. It should only be used when the message is not the main subject of the notification but may give context to a conversation.
