I'm developing an app that needs to play a list of videos on an android TV. At first, I play the video by streaming it while also starting a download for the video. When a specific video is already downloaded and it is the one that needs to be played, I use that downloaded video file and play it. On devices (like the tablet that I used for testing) that is using a WIFI connection, the videos are being downloaded. But the TV where I need to run my app is using a LAN connection. Is there a workaround for this problem?

Currently, this is how I start my downloads.

public void startDownload(VideoAd videoAd) 
 String videoUrl = videoAd.getUrl();
 Uri uri = Uri.parse(videoUrl);

 Environment
 .getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)
 .mkdirs();

 lastDownload = dlMgr.enqueue(new DownloadManager.Request(uri)
 .setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI 

It works. But the problem is it doesn't work on LAN connections.

This is what I currently use in my app.

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) 
 networkArr = connMgr.getAllNetworks();

 Log.d(TAG, "networkArr len: "+networkArr.length);
 for(Network n : networkArr)
 lblNetworks.setText(n.toString()+"n");
 
else
 // Use getAllNetworkInfo()
 NetworkInfo[] networkInfArr = connMgr.getAllNetworkInfo();

 for(NetworkInfo ni : networkInfArr)
 lblNetworks.setText(ni.toString()+"n");
 

My tablet is running Lollipop and the number I'm getting is 103. I can't try it on the TV because it's on a different building.

One potential solution is to get the network you want and bind your process to this network via connectivity manager. See bindProcessToNetwork. You can get the network needed via getAllNetworks() iterate over them and check if the network info matches the network info you would like.

For TV, 'NETWORK_MOBILE' wont work. I would suggest to remove it and try with below mentioned code:-

lastDownload = dlMgr.enqueue(new DownloadManager.Request(uri)
 .setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI)
 .setTitle("Downloading video ad")
 .setDescription("Downloading "+getVideoNameFromLink(videoUrl))
 .setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, getVideoNameFromLink(videoUrl)));

If this code works for TV, you need to apply a check(if it is TV) and handle code accordingly.
