how to solve the out of memory error in android app

Question

i have a custom list view. in that i am listing out images of around 200. The images are been stored in my drawable. I have converted the image to be a bitmap and i am displaying the image as bitmap. Every time when the activity is being opened the images get listed out. Like this when i am calling the activity for around 10 times it gets crashed and the error is

java.lang.OutOfMemoryError: bitmap size exceeds VM budget

then i recycled the bitmaps and by using System.gs function i got the following

Clamp target GC heap from 25.464MB to 24.000MB
GC freed 322 objects / 70664 bytes in 146ms
 Clamp target GC heap from 25.471MB to 24.000MB
 GC freed 2 objects / 48 bytes in 138ms
Forcing collection of SoftReferences for 10720-byte allocation
 Clamp target GC heap from 25.269MB to 24.000MB

 ERROR/dalvikvm-heap(15311): Out of memory on a 10720-byte allocation

Now atlast i got this Out of memory on a 10720-byte allocation error

Now how to resolve the error, please help me friends

Answer 1

Let's run through the checklist for your situation:

1. Is a new activity created every time and you forget to finish out the previous one? If you did, make sure that you profile the app by dumping the memory in .hprof file and use MemoryAnalyzer (http://www.eclipse.org/mat/). Check the number of instances of activity that you have in memory to make sure that it is actually get cleaned up.
2. If you are reloading the same data, you might want to keep this activity around and use FLAG_ACTIVITY_REORDER_TO_FRONT when starting it so it doesn't need to recreate
3. How big is your drawable? You might want to resize it before you set it to your ImageView

Let me think up some more that might be helpful and add later

Have you tried setting the Bitmap variables as Soft-references?
