Setting the APN connection under Options->Advanced Options->TCP-IP does not work, since it doesn’t use these settings.
You need to set your carrier network’s APN and (possibly) authentication info when creating the player with the RTSP stream’s URL.
Example:
String url = "rtsp://10.10.5.125/live.sdp;deviceside=true;apn=Tcell”;
Of course; if the apn does not require authentication, you can safely omit username and password from the URL.
But if it does then we need to add some parameters;
url+=”;tunnelauthusername=user165;tunnelauthpassword=user165password";
Then; just create the player with this URL to watch the RTSP stream on your application:
player = Manager.createPlayer(url);
