Hello,

We use byte-array, instead of file descriptor. I can't tell the exact exception, but It seems to be caused inside AIDL. Should we use file descriptor interface, instead? This time, we temporally worked around using socket API directory.

More details please...

Which exception? Which send method are you using? Do you try to send a byte-array or a filedescriptor?

Hello,

When I'm trying to send a file more than 1M byte as a bundle, some Java exception seems to be raised and it always fails. With Linux application, no problem with files over 1M byte. Do you think of any cause of this problem?

Hi,

Your advice is very helpful. We'll use file descriptor for the next revision.

Thanks, Yoshimi Fujii

Hi,

if you plan to transmit bundles larger than several kByte then you should use the file descriptor method. The heap in Android cannot process large amount of data in a byte-array.

Kind regards, Johannes Morgenroth
