After reading the documentation on Spotify's Android Media Notifications API, https://beta.developer.spotify.com/documentation/android-sdk/guides/android-media-notifications/, I successfully managed to receive the notifications metadata and it is displayed properly on my app.
However, the notifications metadata is only updated when the queue changes, when the track changes, and when playback is changed, so unless one of these three actions happens, the "positionInMs" intent extra isn't sent.
As of right now as a workaround I am simply starting a timer using the time the intent was sent, the last known playback position, and the track duration to track current playback position.
This seemed to work at first, but after further testing I've realized that the timer I set can go out of sync, if the track the user is listening to freezes because of a slow internet connection.
Any ideas to properly track the playback position, while accounting for a slow internet connection? Or are there any alternatives I should look into?
I understand that this question is rather old, but I am going to answer anyway if anyone else comes across it.
I recommend constantly querying Spotify to get the playback position. One way you can do this is by using a timer and querying Spotify every given time frame. The below example queries Spotify every 100ms. If you want to reduce/increase the numbers of queries, you can simply use stopwatch.setClockDelay() and provide your required time
For instance, you can use this timer library
implementation 'com.yashovardhan99.timeit:timeit:1.2.0'
Then use the following code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.spotify);
Stopwatch stopwatch = new Stopwatch();
stopwatch.setOnTickListener(this);
stopwatch.start();
}
#Override
public void onTick(Stopwatch stopwatch) {
Data.getAndroidSpotifyAppRemote().getPlayerApi().getPlayerState().setResultCallback(new CallResult.ResultCallback<PlayerState>() {
#Override
public void onResult(PlayerState playerState) {
Log.d("TAG", playerState.playbackPosition);
}
});
}
Don't forget to add the following code at the top of your class:
implements Stopwatch.OnTickListener

I am using the Spotify android SDK, and I am trying to get a single song to play, and I would like to potentially play a song after the current one is completed. The issue is that after the song completes Spotify plays a random song afterwards. Is it possible to play the song and not have anything else automatically play after it?
I am simply calling the app remotes player API play function,
mSpotifyAppRemote?.getPlayerApi()?.play(uri)
#Mikee you are doing nothing wrong, Spotify messes around with track replay if you are only using the Free version, if you use Premium it will work correctly. Funny enough if you try playing by an alblum or artist that works with the Free version.
I'm not an expert but from their documentation it looks like you could watch the PlayerState. I'm also not sure when a PlayerState event would trigger but if it's coming back relatively often you could check the track value and see if it's gone to null, or another value and work using that.
Here's a Java example from their website:
// Subscribe to PlayerState
mSpotifyAppRemote.getPlayerApi()
.subscribeToPlayerState()
.setEventCallback(new Subscription.EventCallback<PlayerState>() {
public void onEvent(PlayerState playerState) {
// See what values are in playerState, might be able to determine
// if it's now randomly playing?
final Track track = playerState.track;
if (track != null) {
Log.d("MainActivity", track.name + " by " + track.artist.name);
// If the track is now different, your song has finished, stop it?
}
}
});
I've put a few extra comments in the code above that might yield some results!
I want to get the start and end position in Millisecond after à seek.
Actually, I get:
mYouTubePlayer.setPlaybackEventListener(new YouTubePlayer.PlaybackEventListener() {
#Override
public void onSeekTo(int endPositionMillis) {
Log.i("SEEK CURRENT MILLIS", String.valueOf(mYouTubePlayer.getCurrentTimeMillis()));
Log.i("SEEK ENDPOS MILLIS", String.valueOf(endPositionMillis));
}
}
The problem is when the user move the cursor from the timeline, an event onSeekTo is launch, and when I'm inside my onSeekTo methode, I only got the endPositionMillis, but there is no way to get the timer/position before the seek.
If you are referring to the endTime of the video, use the getDurationMillis(). For getting the current time use getCurrentTimeMillis() which you are already using then to go to a specific time of the video use either seekRelativeMillis() or seekToMillis(). With regard to your video not pausing before seeking to a specified time, it will still depend on your implementation if you want to pause the video before going to seeking to that time then playing it.

Hope this helps.
I am trying to utilize ChromeCustomTabs into our project. I ran into several issue when I used mayLaunchUrl. I checked the code Google has on the github. I simply set up an button to test the mayLaunchURL (prerender feature), when I looked up the traffic using chrome dev tool. I did the the traffic and tab got trigger and the url got loaded ( it is simply a GET call with params). However, when I click it multiple times, (after 8-10times, with different params everytime), it STOP working. I stop seeing the requests sent out. (Not seen on chrome dev tool, nor the Proxy I set up).
I wonder if there is a limit times ( restriction) for mayLaunchURL feature, in other words, how many pages we can pre-render in this case? Is there a way to manually cancel the pre-render page and free the resource?
is there a restriction in terms of times to bindCustomTabsService? The way I did to call mayLaunchURL is to have an activity and kill the activity once I finish the tab. Can I bind the service each time even I “kill (finish)” the activtiy every time?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
customTabActivityHelper = new CustomTabActivityHelper();
customTabActivityHelper.setConnectionCallback(this);
}
#Override
protected void onStart() {
super.onStart();
customTabActivityHelper.bindCustomTabsService(this);
}
#Override
public void onCustomTabsConnected() {
Boolean mayLaunchUrlAccepted = customTabActivityHelper.mayLaunchUrl(Uri.parse(“the URL?f=“+params), null, null);
// the mayLaunchUrlAccepted always return true in my case. Even when there is no request sent.
}
Yes, mayLaunchURL() are very expensive in terms of battery/RAM/network, so it is throttled on app UID level. But limits get dropped after some time.
Best strategy is to use mayLaunchURL() if the confidence that the user will navigate to the URL is very high.
There is the "low confidence" mayLaunchURL() which is not throttled, but performs a more limited set of actions (currently preconnect, not specified which, may change). The low confidence mayLaunchURL is triggered by providing null as the uri and a list of URLs in otherLikelyBundles.
I have being upgrading an application to use the new Mobile Android GNSK but I have noticed that using the new MusicID-Stream is a little bit tricky. If the "identifyAlbumAsync" method get executed before the "audioProcessStart" method(since this need to be executed in a different thread), the application just crashes. In the Gracenote Demo application, the "audioProcessStart" method is continuously running so there is no need to synchronize its execution with the "identifyAlbumAsync" method call. Is it the way it is supposed to be used? It will be convenient if the application didn't crashed at least when the methods are not executed in order. Also in our application, we don't want to have the "audioProcessStart" method continuously like it is done in the demo application. We only want to run the "audioProcessStart" method when the user request identification and when the song playing gets identified , we want to stop the audio processing by calling "audioProcessStop". Is there an easy way to do this? Right now, we are getting the Thread where "identifyAlbumAsync" is running to sleep for 2 seconds in order to make sure that the Thread where the "audioProcessStart" method is supposed to run has time to get executed. Thank you in advance for your prompt response
In the upcoming 1.2 release, IGnMusicIdStreamEvents includes a callback that signals audio-processing has started, and an ID can be synced with this, e.g.:
#Override
public void musicIdStreamProcessingStatusEvent( GnMusicIdStreamProcessingStatus status, IGnCancellable canceller ) {
if (GnMusicIdStreamProcessingStatus.kStatusProcessingAudioStarted.compareTo(status) == 0) {
try {
gnMusicIdStream.identifyAlbumAsync();
} catch (GnException e) { }
}
}
Thanks for the feedback, you're right about this issue. Unfortunately right now sleeping is the best solution. But we are adding support for an explicit sync event in an upcoming release, please stay tuned.
In my application I'm downloading movies from the server. Some of them are very big (4gb or more). I tried to implement my own download manager as a service and it was not quit good. On some devices the app just crashes into itself without any notice, and overall the download seems to be too slowly.
So, I wanted to use Android's default DownloadManager, but my only problem is that I can't pause/resume it.
Is there a way to implement that?
From what I can tell by looking at the source code, this isn't supported (although the DownloadManager will automatically retry after failures on its own and after system reboots, etc.).
If you haven't seen this or this already, it looks like there is some useful information there on how to implement your own service yourself with these capabilities.
I found another very impressive library
https://github.com/Trinea/android-common
You can pause by set the Downloads.Impl.COLUMN_CONTROL to Downloads.Impl.CONTROL_PAUSED.
And resume by set the Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_RUN
public void pauseOrResumeDownload(boolean pause, long... ids) {
ContentValues values = new ContentValues();
if (pause) {
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_PAUSED);
} else {
values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_PENDING);
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_RUN);
}
mResolver.update(mBaseUri, values, getWhereClauseForIds(ids), getWhereArgsForIds(ids));
}
