Stream availability checking by name

Since build 1.1.0.28 it is possible to check if a stream with a given name is available on a server for playback, like WebSDK function Stream.available().

To check, do the following:

1. Create a separate Stream object with the stream name to check availability
   code
   

   StreamOptions streamOptions = new StreamOptions(mPlayStreamView.getText().toString());
   Stream stream = session.createStream(streamOptions);
   

2. Create a callback function to receive the stream availability flag and a possible error reason phrase
   code
   

   stream.setAvailableStreamCallback(new AvailableStreamCallback() {
     @Override
     public void on(boolean isAvailable,  String info) {
         runOnUiThread(new Runnable() {
             @Override
             public void run() {
                 mAvailableStreamStatusView.setText(String.valueOf(isAvailable));
                 mAvailableStreamInfoView.setText(info);
             }
         });
     }
   });
   

3. Call Stream.available() method
   code
   

   stream.availableStream();
