Proguard errors when building Chrome for Android

[Ken Rockot]

This is from ToT, DEPS synced, no local changes. I can't seem to build chrome_public_apk as of this morning, in a checkout which I've used to build chrome_public_apk many times before.

I've tried starting from a clean build with no luck. What I'm seeing:

[24653/24671] ACTION //chrome/android:chrome_public_apk__proguard(//build/toolchain/android:arm)
FAILED: gen/chrome/android/chrome_public_apk/chrome_public_apk.proguard.jar ... (snip for brevity)

         You probably need to update the library versions.

Wat do?

If you sync to TOT, the issue should have fixed. The issue is gvr depends on Android N SDK. But N isn't available for TOT yet.

Also, if you build a debug build, it should work.

"is_java_debug = true" is a smaller workaround

So crbug.com/650376 is fixed?

[Biao She]

hmm. Is it still reproducible on TOT for you? The CL that upgrade gvr library has been reverted. I assume it should fix the issue

[Bo Liu]

Yeah checked just now. Trunk looks fixed. You update the bug owner to the right person, then close it.

Thanks, working on ToT!
