android java.lang.OutOfMemoryError

hi, all, when i download large data from website, i got this error information:

I/global (20094): Default buffer size used in BufferedInputStream constructor. It would be better to be explicit if an 8k buffer is required. D/dalvikvm(20094): GC freed 6153 objects / 3650840 bytes in 335ms I/dalvikvm-heap(20094): Forcing collection of SoftReferences for 3599051-byte al location D/dalvikvm(20094): GC freed 320 objects / 11400 bytes in 144ms E/dalvikvm-heap(20094): Out of memory on a 3599051-byte allocation. I/dalvikvm(20094): "Thread-9" prio=5 tid=17 RUNNABLE I/dalvikvm(20094): | group="main" sCount=0 dsCount=0 s=0 obj=0x439b9480 I/dalvikvm(20094): | sysTid=25762 nice=0 sched=0/0 handle=4065496

anyone can help me?

Individual apps do not have access to all available device memory. If you're downloading a large data set consider writing it to the SD card as you go rather than trying to hold it entirely in memory.

OutOfMemory exceptions usually don't have to do with disk memory but heap or memory/ram. (see http://java.sun.com/j2se/1.4.2/docs/api/java/lang/OutOfMemoryError.html)

hi, adamp, i was wirte to SDCard, but it still OutOfMemory. Could you tell me how to recycle Drawable?

@Toni: You can often process data in chunks to or from local storage in situations where attempting to load the entire data set into memory at once would result in OOM.@xiangdream: If your large data are images in the form of Drawables (BitmapDrawables?) take a look at the BitmapFactory decoding methods and the inSampleSize field of BitmapFactory.Options. You can resample an image to a smaller size while loading it to save memory. http://developer.android.com/reference/android/graphics/BitmapFactory.html Some more information about what you're trying to do would be helpful. :)
