android java.lang.OutOfMemoryError

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.

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.
