Android: execute code in regular intervals

You can do that using the below code,
Hope it helps!

final Handler handler = new Handler(); 
Runnable runnable = new Runnable() { 

    @Override 
    public void run() { 
        try{
            //do your code here
        }
        catch (Exception e) {
            // TODO: handle exception
        }
        finally{
            //also call the same runnable to call it at regular interval
            handler.postDelayed(this, 1000); 
        }
    } 
}; 

//runnable must be execute once
handler.post(runnable);
