These warnings are shown in the Console window.
Failed to add the asset file size for b24777957ec9d44649061dab714daf90
Failed to add the asset file size for sharedassets0.resource
Failed to add the asset file size for sharedassets10.resource
What does this mean and what causes these warnings?
Unity 5.2.0f3 doesn’t show them.
This is happening to me too. And my Android builds are no longer working…
I have reported the bug: 730075
My builds seem to work fine, at least on the device that I am using to verify the builds.
My builds are working so far, but the message appears to me as well:
Same here. App builds fine though and there’s no problem during play.
For me it happens when building for Android. And when I run the app on the android device there is no audio (loaded from resources).
I’m testing it in Unity 5.2.1f1
same here
Same error for two assets on 5.2.1
Same here. In my case, the shown guid points to FacebookSettings.cs
@mark71 : whare can I find your bug report? I could not find 730075 in the issue tracker.
I don’t know why it is not shown in the issue tracker, the bug report number is correct.
How do you match the GUIDs?
Getting all sorts of these errors… in 5.2.1p1
Opened a bug report, case: 730952
Yes, I misspelled add (not ass, Sorry, UT)…lol…leave it to me to turn a simple, 3-letter word into foul language 
I think this might be related to resource loading…it seems like everyone in this thread is using assets from a resource folder.
(there must be some kind of moderation over the issue tracker - i cant see 730075 nor 730952)
@neonblue : i just did a grep. having asset serialization set to text probably helps
There is something definitely wrong here…This happens on Android builds for any of my projects.
These are the build warnings:

The first warning shows up on every project. Sometimes I get Failed to add the asset file size for sharedassets0.resource.
My builds are also behaving as though some scripts are missing. Can anyone else confirm strange behavior on builds? My serialized dictionaries seem to be affected in builds only.
@ekt I believe that bugs have to be reviewed before they are posted to the tracker.
I haven’t noticed any strange behaviour, to me it seems to be working as before.
Happens on Android builds, not on winclient
building from the command line, there’s a stack trace, might be usefull for unity devs

In my case it’s already set to text. Didn’t help. Also I’ve tried several different sound settings (in my case I don’t hear sounds living in resources on android). Didn’t help either.
Ok, this explains why I’m seeing issues on my display after deployment… Some resources that are key for layout are not getting included. This is a huge deal…
I’m seeing the same type of errors, the build seems to work fine though.
Yes, I have resources missing from builds as well 
@ekt How were you able to build from the command line? I would like to take a look at the stack traces
Hello all,
The warning messages you’re seeing is part of a change we introduced in the latest patch in order to include the contents of the Resources folder in the output stats logfile, which is a feature that has been requested by some of our customers. I’ll analyze the case reports you have submitted and find out why are the warning messages being printed in the first place, because that shouldn’t really be the case under normal circumstances.
Notice that this new feature doesn’t have any impact whatsoever in the build process itself; it only affects the output stats calculation. So if you’re having issues when building your projects, the problem might be something else.
Edit: typo.
