in Activity, My function is like this....

private void setupSlideShow(ArrayList<String> titles, ArrayList<String> desc) {

    realViewSwitcher = (HorizontalPager) findViewById(R.id.horizontalPager);
    realViewSwitcher.removeAllViews();

    LayoutInflater inflater = getLayoutInflater();

    for (int i = 0; i < titles.size(); i++) {

        View v = inflater.inflate(R.layout.whats_new_slide_show_item, null);
        TextView titleTV = (TextView) v
                .findViewById(R.id.whats_new_item_title);
        titleTV.setTypeface(CommonFunctions.getBold(getContext()));
        titleTV.setText(titles.get(i));

        TextView descTV = (TextView) v
                .findViewById(R.id.whats_new_item_desc);
        descTV.setTypeface(CommonFunctions.getNormal(getContext()));
        descTV.setText(desc.get(i));

        ImageView img = (ImageView) v.findViewById(R.id.img_whats_slide);
        img.setImageResource(imgResources.get(i));

        realViewSwitcher.addView(v);

    }

    realViewSwitcher.setOnScreenSwitchListener(onScreenSwitchListener);

}

Answer 1

It looks like you are trying to pre-load all your images for your slideshow. If you redesign your app to only load images when they are viewed, it will have much less peak memory usage which will help you avoid out-of-memory issues.

Answer 2

I have ran into the out of memmory error so i will try to tell about that.

Things you should try:

1) Clear resourses (System.gc(); and Runtime.getRuntime().gc();) on pause or on destroy on previous activity.

2) (Which was my problem) Make sure that your images are big as the bigest screen your app is running on or suporting.(I had two design elements with resolution 1000x486 and it gave me out of memmory error).
