Infinite Loop a Handler to classify images

I need to classify an images recorded by my camera as often as possible in a infinite loop. Every classification takes about 0.5 seconds. What is the best way to implement this in android?

So far I tried to add a Handler inside onCreate, but it seems I cannot just call my method from there:

@Override
protected void onCreate(Bundle savedInstanceState) {
    [...]
    mHandler = new Handler();
    Runnable mRunnable = new Runnable() {
        @Override
        public void run() {
            Log.d("myLog","run was called");
            mHandler.postDelayed(this, 1000);
            TakeScreenshot(); // <-- this is my method which doesn't work 
        }
    };

    mHandler.postDelayed(mRunnable,1000);

}

The method TakeScreenshot(); is taken from this post. I basically need to modify it such that it takes a screenshot as often as it can instead of only after pressing the button.

A `Handler`, perhaps? What have you tried? – OneCricketeer Apr 26 '16 at 18:51

Why it does not work? Is in other class and not static or what? – Marcin Orlowski Apr 26 '16 at 18:57
Where did you define the `TakeScreenshot()` method? If it is in the Activity, you should be able to call it. – OneCricketeer Apr 26 '16 at 18:58
If you put a breakpoint in the `run` function, or even in your `TakeScreenshot()` function does the breakpoint hit? if neither hit, at least we know where it is breaking. I suppose we need to know what is not working, is there an error? – Krum110487 Apr 26 '16 at 19:05
Thanks @Krum110487 . I guess the error is indeed inside `TakeScreenshot();`. It's calling for some non global variables. I try to fix that and let you know if it runs – mcExchange Apr 26 '16 at 19:07
