What version of the build tools are you using? We haven't seen the issue, but similar problems have been reported with 21.0.0 and 21.0.1 on other projects.

From my app's build.gradle file in the android closure:

buildToolsVersion "21.1.2"

What OS and Java version are you using? Would you be willing to share a stacktrace?

If possible, I'd be curious to see if compilation using build tools circa version 19 works. In the meantime, we'll see if we can reproduce the issue.

Using Yosemite 10.10.1 (14B25), my JDK is jdk1.7.0_51.jdk. And unfortunately I need to use v21+ of the Build Tools to use RecyclerView in my app, so I can't just drop down the build tools.

The app builds - I'm just getting a ton of log barf in the process.

This is just an issue with the version of libpng aapt uses (https://code.google.com/p/android/issues/detail?id=77704).

These are just warnings because the newer libpng we built against is stricter about the color profile. We will fix this in an upcoming release, but this shouldn't be an issue.

Future updates of the build tools should fix this, for now it's just noise.

@designatednerd did this answer your issue?

@lkorth Yes, but I'd recommend leaving this open until the noise goes away so that anyone else encountering this issue is able to see what the problem is.

https://groups.google.com/forum/#!msg/adt-dev/rjTQ_STR3OE/-UcNQRISTKsJ has a solution for this. Just need to clean up the metadata on the PNGs.

Stripped assets coming soon to a release near you!

Thanks!

Just to note, there will still be some warnings generated because of the card form. I have made the commit to strip the metadata in the card form, however it won't take effect until the next version of the card form is released and Drop-in is updated.
