Out of memory error while loading hundred of bitmap images in Scroll view in android

this case is often come while we getting bitmap so just use lazy loading. just take a look on this example http://sunil-android.blogspot.in/2013/09/lazy-loading-image-download-from.html

To prevent your application from soaking up CPU time without getting anything done, the JVM throws this Error so that you have a chance of diagnosing the problem.

Its because of large bitmap memory in stored in native area so it better i suggest you use libraries like Universal Image Loader or

Bitmap Fun from android

You have to find out when the OOM error occurs. Is it when you have too much bitmap cache in memory without releasing or you just meet it when you're decoding certain bitmap?

For the first situation, I think you should manage your bitmap cache yourself or using some effective 3rd-party library which mentions above.

For the second situation, I've met it on some low-performance mobile(usually with 512MB or less memory), when you decode a bitmap to requested size, it may needs a rather large memory to store the bitmap, for 240dpi devices, it's about 800 * 480 * 4 = 1.5MB, however you may fail to allocate that much memory on some machines cause they may have strict memory manage strategy to prevent that much memory allocation. You should just catch the OOM error and continue rather than get a crush.

Loading a bitmap in 1280x800 display will take 1280x800x4 byte (~4MB) memory. Java heap size is limited (~50MB) so you can not use lots of large bitmaps in your app. Using cache and reusing bitmap objects are necessary while working with bitmaps but another useful trick is to use larger hip size! to do so, add android:largeHeap="true" to Application tag in your manifest. It increases hip size to 4 or 5 times larger (~250MB) than normal. I hope this help other people reaching this thread while they search!
