Android gallery of drawables

Question

I'm creating a simple Gallery of drawables - each of them is almost the size of a screen, so they require quite much memory. For each entry I'm creating a custom LinearLayout with ImageView and TextView for the title. As most of you know, android Gallery doesn't recycle views so it gallery will crash easily on low-memory phones (after loading 4 drawables on 16mb ram limit, in my case).

Here's the simple question - how do you implement such gallery, so it won't run out of the memory? How do you recycle these images? A working code example would be great.

Few notes:

• inSampleSize isn't a way to go, I can't scale these images down

• Calling recycle() on Drawable's loaded from resource is impossible, as it will crash on Android 4.0+ (it will recycle the drawable in their internal cache)

• Don't ask me to post the code, as there is no.

You shouldn't be using Gallery because it's deprecated. Especially since there isn't any code written so far. The documentation suggests using a HorizontalScrollView or ViewPager.

I feel a ViewPager is what your looking for because it will only keep at most 3 pictures in memory and handels all the recycling for you. Here is a post with more information about how to implement one android viewPager implementation
