Reducing Memory leaks Android

Question

When dealing with images in android for bitmap objects I used to recycle them in order to save when moves to the next screen. But there are times I had to use drawable s instead of bitmaps any way of dealing with these.

Recycle drawable objects just like bitmaps bitmap.recycle() method.

Thanks

Here you go with libraries for better image management:

• Picasso
• Fresco

I gave you links to description of libraries on purpose, so you get to know them at least a bit before you just drop them in project. Understanding what they are for and basic concepts about them it will will save you a lot of time later.

Here is how to apply HolderPattern to your list to avoid creating of new object over and over.. Again I would advice to read carefully not just to copy-paste.

You can use third party image libraries. Some good libraries are:

1. Nostra’s Universal Image loader

2. Picasso

3. UrlImageViewHelper by Koush

4. Volley – by Android team @ Google (mainly network library)

5. Novoda’s Image loader (depraceted)
