Unable to read XML in Unity 5 Android

Question

I just migrated to Unity 5 (and Oculus Mobile 0.5.0 as well) and I'm facing the following issue only in release mode (i.e. not when the "Development Build" flag is checked) any time I try to read an xml file from the Galaxy Note 4 device storage:

UnauthorizedAccessException: Access to the path "/sdcard/Oculus/Product/Settings.xml" is denied.

Here's the offending code:

 FileStream stream = new FileStream(filename, FileMode.Open);

Everything ran fine in previous versions, and still runs fine in the "Development Build". Anyone know why this might be happening?

(Note: It's quite possible that this may be a problem on the Oculus side, but why would only a Release build be throwing this exception??)

Thanks, Saswat

Issue resolved. Looks like using that filestream constructor always opens with ReadWrite permissions. And I guess the release build for Unity 5 is stricter about those permissions? Anyhow, this does the trick:

FileStream stream = new FileStream(filename, FileMode.Open, FileAccess.Read);

your case reminds me of giving a permission to Android manifest file.

check this first.
