You don't have to read the whole file in one go. Just make sure you don't attempt to read more than the length of the file (e.g., read in 4kB chunks, but the read request for the last chunk should not request more than the length of the last chunk). Try this, to see if it works. It's not a good solution, but, if it works, it will at least give us all an idea what the issue is.
Great On the transfer side there are no improvements. I lowered the buffer size to 2048, not it SEEMS to be working on the simulator, but not on the BB. Could this be a problem of the 8900? Is there anybody from RIM who can look into this?
If nobody can help me out, how can I open a ticket at RIM to get help? This is a very simple application and a simple network transfer which is NOT working as designed.
What would also help is a short app for the Blackberry which simply downloads a >10MB file from a webserver - nothing more. I need a direect tcp wifi connection.
I stripped the test down to the essentials, and I can confirm that I'm getting this issue on some simulators (including v5.0). I suggest you create a small test app that demonstrates the issue without doing anything extraneous (e.g., read from the InputStream without saving the results anywhere and just count the number of bytes read) and then submit this to RIM's Developer Issue Tracker.
P.S. Try this for as a yet another workaround: read the stream byte-by-byte using "int InputStream.read()" -- it's slower and more taxing on the CPU, but, may be, it works.
On the simulator it takes a lot of loops until it hangs, one time 51, one time never - well I gave up at 90. Using the Blackberry it took me 3 to 5 loops for the process to be hanging - with and without saving the file.
Perhaps some people can test this, simply put in a (local) URL with some file and put in a local path to save the file. Start the process, wait for the security dialog to be opened (if any) and then count the loops until the app hangs. Sometimes it hangs at 100% sometimes between 0% and 100%.
Please test with AND without saving the file, reboot the device after a failed test.
