prioritise Async task over web view - android-studio

Question

My android application has web-view and control buttons, web view streams live video from raspberry pi camera and on button press the traction commands(on,off,right,left) goes to the redis-DB on the same raspberry-pi
my observations is when web view streams video the control commands on button pressed reach pi at very slow speed
my priority is control first and then streaming how to accomplish the same?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.loadUrl("http://192.168.0.190:8000");
Log.e("aaa","Streaming video");
}
//on button clicked
public void StartTraction(View view) {
MyAsyncTaskStart myAsyncTasks = new MyAsyncTaskStart();
myAsyncTasks.execute();
}
public class MyAsyncTaskStart extends AsyncTask<String, String, String> {
#Override
protected String doInBackground(String... strings) {
try {
Jedis jedis = new Jedis("192.168.0.190", 6379);
jedis.set("motorKey","ON");
jedis.disconnect();
} catch (JedisConnectionException e) {
} catch (NullPointerException e1) {
} catch (Exception e1) {
}
return "";
}
#Override
protected void onPostExecute(String s) {
}
}
}
