How to use Handle without increase Memory in Android

Question

In my application I use ViewPager for show some data and I want set auto scroll between of pages in every 5sec.

I use below code for auto scroll between of pages in every 5sec.

private int page = 0;
private Handler handler;
private int delay = 5000;
private Runnable runnable = new Runnable() {
    public void run() {
        if (homeRecentPostAdapter.getCount() == page) {
            page = 0;
        } else {
            page++;
        }
        homePage_recentViewPager.setCurrentItem(page, true);
        handler.postDelayed(this, delay);
    }
};

    homePage_recentViewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {

        }

        @Override
        public void onPageSelected(int position) {
            page = position;
        }

        @Override
        public void onPageScrollStateChanged(int state) {

        }
    });

Without use this Thread and Handle memory usage (into profiler tab) has 80mb, but after use above codes for set auto scroll memory usage upper to 120mb and every 5 set upper this usage, then after 2min receive to 250mb !

How can I fix it? how can use auto scroll without increase memory ?

Answer 1

check your ViewPager, maybe it is creating new instance on each page turn. If your provide the code I might be able to point it out.
