Try much with many help from google but no luck

Could you help me to resolve this?

Thank you.

You are not supposed to encode large files in the xml payload. It is merely running out of memory since it it trying to parse it. Change to just submit the url via the webservice and do a normal http get to download the actual binary.

Thank you for your answer,

Mean that i should not use https, right?

Anyway to overcome this? I need secure file transfer.

Please help.

[Manfred Moser]

I mean you should not use SOAP to transfer large files.

Oh, I see now.

However, i google someone said that we can change to stream to file on android, instead of parse directly on memory. They give example modifying directly in HttpTransportSE.java version 2.5.

Do you know about this?

[phan son]

I found that in version 3.0, we can set outputFile. I tried, but no luck.

Do you know about this?

Thank you.

[Manfred Moser]

Yes of course... it works .. see the javadoc and commit history. It should work and stream the file to storage.
