System thread inside a Timer in Android

So I have a Timer in my Activity and I want to run that every 10 seconds.

I created a System.Threading.Timer:

timer = new Timer ((o) => {
    Action syncAct = new Action (async delegate() {
        await FetchData();
    });

    RunOnUiThread (syncAct);
}, null, 0, 10000);

The problem here is that await FetchData() takes longer than 10 seconds and that causes the timer to go on forever. I need the timer to start every time AFTER the sync completes. How can I do that?

Thank you for your time.

Try spawning a thread that sleeps for 10 seconds and runs the code.

Roughly like so:

\\declare doRun as a boolean field
new Thread()
{
    public void run()
    {
        yourClass.doRun = true;
        while(yourClass.doRun)
        {
            fetchData();
            try {
                sleep(10000);
            } catch(InterruptedException e)
                break; 
            }
        }
    }
}.start();

Set doRun to false to exit the thread. Or you could assign the thread to a variable instead of an anonymous thread, and call yourThread.interrupt();
