Hello I have problem with delay in stream video on android.
I have a delay of about 8 seconds and it is very annoying. There is no delay on the computer.
This is a stream from camera like gopro via wifi --> rtsp.
I found this topic on SO...
Streaming videos on VideoView
And I have the same problem as Akeshwar Jha. Unfortunately, I don't know Java. Could someone help me modify the design according to what Akeshwar Jha gave ??

Thank you in advance for your help.
What I am trying to do is that as any incoming call is received I want to start a service ChatHeadService which shows a chat head.
Basically I want to run this command, but as I run the app my app stops at this command.
startService(new Intent(getApplication(), ChatHeadService.class));
This is my java class CallHelper in which I am using thread to use the startService() method.

You're not reusing your list items. This is why the list is starting to "stutter".
There are a lot of answers on this problem that display the concept of reusing ListView items.
Like this one
In general: within your getView method, check if the convertView is null. If it is, inflate your view. If it's not null, just insert the items that you want to display. This should solve your stuttering list view problem.
Please use for existing layout in BaseAdpter as below
ViewHolder holder = null;
if ( convertView == null )
{
/* There is no view at this position, we create a new one.
In this case by inflating an xml layout */
convertView = mInflater.inflate(R.layout.listview_item, null);
holder = new ViewHolder();
holder.toggleOk = (ToggleButton) convertView.findViewById( R.id.togOk );
convertView.setTag (holder);
}
else
{
/* We recycle a View that already exists */
holder = (ViewHolder) convertView.getTag ();
}
this may helps you
The problem is, the onPanChanged() method gets called twice causing the points to flash before they are plotted every time a user moves or pans around the map. What can I do to make the onPanChanged() method only get called once. In the code, I even try to turn off the listener and turn it back on when I exit the AsyncTask.
I would like you to share some of your thoughts and opinions.
