Out Of Memory on file Download

[sumit-anantwar]

I am trying to download a .tgz archive of 50mb, and I am getting OOM on Samsung Galaxy Tab 2. But the file downloads without any issues on more recent devices and also on the simulator.
Seems that the default buffer size is larger than the available free memory on older devices.
Is there a way to specify the buffer size ?

I'm sorry, but default AsyncHttpResponseHandler is not meant to handle such large data. Use FileAsyncHttpResponseHandler.java or provide your own ResponseHandler, that would stream the file directly to filesystem, instead of caching it in memory and writing it out later
