I have a service class which updates a static variable in my activity, I am having trouble trying to create code that will constantly run every 5 seconds to update say a textview.. using this variable.
How can I go about doing this?

2Look into using LocalBroadcastReceiver or an event bus. – Doug Stevenson Mar 10 '16 at 06:20

You can use a handler for running every 5 seconds See this sample code
Handler h = new Handler();
int delay = 5000; //milliseconds
h.postDelayed(new Runnable(){
public void run(){
//do something
h.postDelayed(this, delay);
}
}, delay);
and in run method you can update your textview

Thank you, it's telling me delay is accessed within inner class, needs to be declared final? – David Hasselhof the 2nd Mar 10 '16 at 06:27

Worked a charm, had to declare delay and the handler final. thanks so much. – David Hasselhof the 2nd Mar 10 '16 at 07:14
