Cast videos in queue by Chromecast stop playing video automatically after some time

Cast video using Chromecast in a queue is working fine. As per my requirement, it's need to play video constantly for hours on the screen. For that i get bunch of video urls from server for 5 to 10 videos. When 2 video are remain i get new bunch and i append in a queue. Videos are with the length around 40 to 50 seconds.
It continues play for about 45 to 60 min not more than that. It stops than.
I want it to play for hours...
Can any one Help me to come out from this issue. Any help will be useful for me.
Here is my code to play queue.
public void queuePlay(ArrayList<CastModel> data) {
ArrayList<MediaQueueItem> queueList = new ArrayList<>();
for (int i = 0; i < data.size(); i++) {
MediaMetadata mediaMetadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_MOVIE);
mediaMetadata.putString(MediaMetadata.KEY_TITLE, data.get(i).vTitle);
mediaMetadata.putString(MediaMetadata.KEY_SUBTITLE, data.get(i).vName);
mediaMetadata.addImage(new WebImage(Uri.parse(data.get(i).vImage)));
JSONObject extraData = null;
try {
extraData = getJsonOfObject(data.get(i));
if (extraData == null)
extraData = new JSONObject();
} catch (Exception e) {
Log.i(TAG, "queuePlay: exception " + e.toString());
}
MediaInfo mediaInfo = new MediaInfo.Builder(data.get(i).vVideo)
.setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
.setContentType("videos/mp4")
.setMetadata(mediaMetadata)
.setCustomData(extraData)
.setStreamDuration(30 * 1000)
.build();
MediaQueueItem item = new MediaQueueItem.Builder(mediaInfo).build();
queueList.add(item);
}
MediaQueueItem[] queueArray = new MediaQueueItem[queueList.size()];
queueArray = queueList.toArray(queueArray);
remoteMediaClient = sessionManager.getCurrentCastSession().getRemoteMediaClient();
remoteMediaClient.queueLoad(queueArray, 0, REPEAT_MODE_REPEAT_OFF, null);
remoteMediaClient.addListener(new RemoteMediaClient.Listener() {
#Override
public void onStatusUpdated() {
try {
Thread.sleep(1000); // Hold for a while
} catch (InterruptedException e) {
e.printStackTrace();
}
MediaStatus mMediaStatus = remoteMediaClient.getMediaStatus();
if (mMediaStatus != null && mMediaStatus.getQueueItems() != null) {
if (queueItemPlayedPosition < mMediaStatus.getCurrentItemId()) {
Log.w(TAG, "onStatusUpdated: Delete video " + queueItemPlayedPosition);
updateCastList(false);
queueItemPlayedPosition++;
}
Log.e(TAG, "onStatusUpdated getCurrentItemId " + remoteMediaClient.getMediaStatus().getCurrentItemId() + " *** onStatusUpdated: getQueueItemCount *** " + mMediaStatus.getQueueItemCount());
}
}
#Override
public void onMetadataUpdated() {
}
#Override
public void onQueueStatusUpdated() {
}
#Override
public void onPreloadStatusUpdated() {
}
#Override
public void onSendingRemoteMediaRequest() {
}
});
}

Haven't played with Cast SDK a lot but found this Autoplay & Queueing APIs which might provide what you're looking for as it mentions ways to play videos continuously using autoplay.

How to pass score parameter in play-services-turn-based methods?

I have just started exploring google-play-services-turnbased APIs. Till now I have been successful in creating a match. But from the documentation I haven't been able to figure out how to player's score after he completes his turn.
This is my onClickStartMatch method.
public void onStartMatchClicked() {
Intent intent =
Games.TurnBasedMultiplayer.getSelectOpponentsIntent(mHelper.getApiClient(), 1, 7, true);
startActivityForResult(intent, RC_SELECT_PLAYERS);
}
This is my onActivityResult method in my main activity class.
if (request == RC_SELECT_PLAYERS) {
if (response != RESULT_OK) {
// user canceled
return;
}
// Get the invitee list.
final ArrayList<String> invitees =
data.getStringArrayListExtra(Games.EXTRA_PLAYER_IDS);
// Get auto-match criteria.
Bundle autoMatchCriteria = null;
int minAutoMatchPlayers = data.getIntExtra(
Multiplayer.EXTRA_MIN_AUTOMATCH_PLAYERS, 0);
int maxAutoMatchPlayers = data.getIntExtra(
Multiplayer.EXTRA_MAX_AUTOMATCH_PLAYERS, 0);
if (minAutoMatchPlayers > 0) {
autoMatchCriteria = RoomConfig.createAutoMatchCriteria(
minAutoMatchPlayers, maxAutoMatchPlayers, 0);
} else {
autoMatchCriteria = null;
}
TurnBasedMatchConfig tbmc = TurnBasedMatchConfig.builder()
.addInvitedPlayers(invitees)
.setAutoMatchCriteria(autoMatchCriteria)
.build();
// Create and start the match.
Games.TurnBasedMultiplayer
.createMatch(mHelper.getApiClient(), tbmc)
.setResultCallback(new MatchInitiatedCallback());
}
This is my MatchInitiatedCallback class
public class MatchInitiatedCallback implements
ResultCallback<TurnBasedMultiplayer.InitiateMatchResult>,OnTurnBasedMatchUpdateReceivedListener {
#Override
public void onResult(TurnBasedMultiplayer.InitiateMatchResult result) {
// Check if the status code is not success.
Status status = result.getStatus();
if (status.isSuccess()) {
Log.d("turnbased","Turn Based Match Initiated successfully with result: "+status.getStatusMessage());
return;
}
TurnBasedMatch match = result.getMatch();
// If this player is not the first player in this match, continue.
if (match.getData() != null) {
showTurnUI(match);
return;
}
// Otherwise, this is the first player. Initialize the game state.
initGame(match);
// Let the player take the first turn
showTurnUI(match);
}
public void showTurnUI(TurnBasedMatch match){
if(match.getStatus() == TurnBasedMatch.MATCH_STATUS_ACTIVE){
if(match.getTurnStatus() == TurnBasedMatch.MATCH_TURN_STATUS_MY_TURN){
turnBasedMatchData = match.getData();
Games.TurnBasedMultiplayer.takeTurn(mHelper.getApiClient(),match.getMatchId(), "score:400".getBytes(Charset.forName("UTF-16")),null).setResultCallback(updateMatchResult());
}
}
}
public void initGame(TurnBasedMatch match){
Games.TurnBasedMultiplayer.takeTurn(mHelper.getApiClient(),match.getMatchId(),"score:605".getBytes(Charset.forName("UTF-16")),match.getParticipantId(Games.Players.getCurrentPlayerId(mHelper.getApiClient()))).setResultCallback(updateMatchResult());
}
public ResultCallback<TurnBasedMultiplayer.UpdateMatchResult> updateMatchResult(){
return null;
}
#Override
public void onTurnBasedMatchReceived(TurnBasedMatch turnBasedMatch) {
Log.d("turn-based","Player played his turn");
}
#Override
public void onTurnBasedMatchRemoved(String s) {
}
}
}
Also it would helpful if some can properly explain how to continue a game a game from start and when to submit score and how.

Figured it out. This is how you can do it.
public byte[] persist() {
JSONObject retVal = new JSONObject();
try {
retVal.put("turnCounter", 2);
retVal.put("score1",100);
retVal.put("score2",200);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String st = retVal.toString();
Log.d(TAG, "==== PERSISTING\n" + st);
return st.getBytes(Charset.forName("UTF-8"));
}
Games.TurnBasedMultiplayer.takeTurn(mHelper.getApiClient(),match.getMatchId(),persist(),null).setResultCallback(updateMatchResult());

NFC tag(for NfcA) scan works only from the second time

I wrote a custom plugin to read blocks of data from an NfcA(i.e.non-ndef) tag. It seems to work fine , but only after the second scan. I am using Activity intent to derive the "NfcAdapter.EXTRA_TAG" to later use it for reading the values. I am also updating the Intents in onNewIntent(). OnNewIntent gets called after the second scan and after that I get result all the time.But in the first scan onNewIntent does not gets called, hence I end up using the Activity tag that does not have "NfcAdapter.EXTRA_TAG", hence I get null. Please see the my code below.
SE_NfcA.java(my native code for plugin)

};
I guess I have messed up with the Intents/Activity Life-Cycle, please help. TIA!

I found a tweak/hack and made it to work.
Before making any call to read or write, I made one dummy Initialize call.
window.echo("Initialize");
window.echo("readBlock#88");//call to plugin to read.
And in the native code of the plugin, on receiving the "Initialize" token I made a startNFC() call.
else if(TypeOfTalking.equalsIgnoreCase("Initialize"))
{
startNfc();

WIFI P2P stops discovering peers and doesn't accept connections after 2 minutes

I have been messing around with the following issue for about 2 months now.
I am building an application on a custom android board which will act as a wifi display (WFD). When I boot the board, I can easily connect from several different phones (LG Optimus G, LG Optimus G pro, Samsung S3 and S4). After connecting and watching the screen being duplicated on the TV screen attached to the custom board, I can then disconnect and if I reconnect within 2 minutes, I can connect again.
If I boot the board (or disconnect) and then wait 2 minutes, the device no longer sees the phones, and the phones sometimes sees the board, and sometimes not. If the phone sees the board, I can initiate a connect, but I cannot connect succesfully.
I have tried all kind of options, but none seem viable.
The board is running on AOSP 4.2.2
I have right now some complicated code that does restart the discoverPeers function every 40 seconds, as normally it stops after 30 seconds. Besides that I disable WFD and re-enable it, with a 4 second delay between it.
I also tried disabling and reenabling p2p and the channel, all with no result.
Below is my code, the receiver is in a separate class.

In the logging initially I see that the device and the phone connect successfully.
After disconnect, I see the devices being lost in the log, and after that, when I try to connect, I see the message:
I/wpa_supplicant(1839): [CTRL_IFACE]p2p0: P2P_CONNECT da:57:ef:cb:8e:be pbc go_intent=0
After this everything stops, the application is still running, I could see that from a log line that runs every second in the thread that stops and restarts the discovery every 40 seconds.
If anyone has any idea left why this behavior is happening, let me know. The only way to recover right now is to reboot the board (but that is not an option).
Thanks for your replies,

How to send and receive Voice Stream using RTP

I am new in SIP call using RTP, now I am trying to send and receive
voice streams using RTP for sip call. I am done with connecting
two emulators and able to send INVITE and INVITE-ACK using jain sip.
After I got an Ack I want to start RTP for media streaming, I use the RtpPacket
function to send and receive
I use RtpFunction to send media with all RTP header like this:
byte Version;
boolean Padding;
boolean Extension;
byte CC;
boolean Marker;
byte PayloadType;
short SequenceNumber;
int TimeStamp;
Please give some ideas and actual links where I can find an answer.

This can be achieved in a simpler manner
AudioManager audio = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audio.setMode(AudioManager.MODE_IN_COMMUNICATION);
audioGroup = new AudioGroup();
audioGroup.setMode(AudioGroup.MODE_ECHO_SUPPRESSION);
audioStream = new AudioStream(InetAddress.getByAddress(getLocalIPAddress()));
audioStream.setCodec(AudioCodec.PCMU);
audioStream.setMode(RtpStream.MODE_NORMAL);
audioStream.associate(InetAddress.getByName(SipStackAndroid.getRemoteIp()), REMOTE_PORT);
audioStream.join(audioGroup);

We send and receive RTP data using RTPpacket.
