OutOfMemory Exception on 35MB File Upload

[quantum0813]

I am getting an OutOfMemory exception when trying to upload a 35MB file. This is occurring on a Samsung Galaxy S5 running Android 4.4.2. Here is the stack trace:

1. Can you sistematically replicate this behaviour every time with the same file?
2. Android 4.4.2 uses OkHttp 1.5 internally to provide HttpUrlConnection implementation. That's pretty old. Try to switch to OkHttp stack implementation (which uses OkHttp 3.2.0), by following this guide, without changing anything else and tell me if you still have the same behaviour

@quantum0813 I think the problem is exactly the same reported here. It's a bug in the old OkHttp implementation used by Android 4.4, which has been fixed, so try to switch the http stack as I've described and let me know. If you target multiple android versions, then I definitely advise you to do that, to have a consistent networking behaviour.

Thanks for your quick reply. I have updated my app to use the OkHttp stack implementation. I'll do some more testing, and report back.

[gotev]

@quantum0813 are your tests successful?

Closing due to lack of feedback. Made some tests with the proposed solution, and the problem doesn't occur. Read this
