Dont know the exact reason. I have solved this problem by giving system.gc(); . But this is not the exact way — Zacharias Manuel

If you have problem with memory then you have to go wiht two options First.=> You have to decode image using Bitmap or Second => Download image and save it in temporary folder & use it. When you donnt need delete all files from folder.

For Download image and save it in folder check this link

For Decoding Check this link from stackoverflow. Maybe this will help you. Thanks

It's a common problem, and I think you should use for your bitmap a collection of SoftReference. Check the doc and online ressources for SoftReference : it will allow Android to clear the space taken by the bitmap when needed.

On pre ICS phones the bitmaps were created on the dalvik heap and their memory cleaning was called in the finalizer which isn't a silver buller http://code.google.com/p/android/issues/detail?id=8488

Use a bitmap object and make sure call the recycle method

I think you mean call the Bitmap.recycle method. Yup, you have to keep track of your bitmaps and remember to dispose of them properly, you can’t just throw them away like a Java object.
