"Chunked reading" does not really help when you need to parse json or xml. We would require A) streamed File I/O B) a stream based json parser
I guess jQuery's Ajax (getJSON) does exactly this on the HTTP response stream. Does anybody now if I could "abuse" jQuery's ajax to parse json from the local filesystem (not a file in the apk, but one that is on the devices's filesystem). I tried with the file:/// URI but didn't get hold of the file Š Thx Clemens ----------------------------------------- Yup, that's because the data is effectively doubled as it needs to be passed from the native side to the Javascript side. When you are downloading the data from the net it is just coming down to the JavaScript side of things. Hmmm...I should open an improvement for file reading to do it in chunks.

But why then can I download the "same amount" to my device and then save it? Anda t the very same time the content (being json) is decoded into RAM ... Only when trying to load from FS I get the OOM ... -----Ursprüngliche Nachricht----- Von: Simon MacDonald [mailto:simo...@gmail.com] Gesendet: Donnerstag, 6.

Each application has a piece of the system memory on the HTC Desire the RAM is 384 MB while on the Samsung Galaxy S2 has 1 GB or RAM. I'm making the assumption that the available memory for each application is much smaller on the HTC deviceas it has one third the memory of the Samsung and that's probably why you are getting the OOM exception.

Is 2.5M "too much"? Thx Clemens Note 1: I am able to download the very file (through $.ajax) and save it locally using FileWriter. Could it be that in "this case" the file is being streamed and not completely read into RAM? Note 2: Having no problem on a Samsung Galaxy2 with Andorid 4.03
