Answer 1

I have exactly same problem in Android Studio 2.3. I wasted 2 days to solve this problem.

Your problem is

AAPT err(Facade for 596378712): \\?\C:\Users\Я\.android\build- .....

Folder name of your account(reverse R?) is not ascii folder name, so build-cache cannot recognize your folder.

To Solve:

1. Change folder name : it's impossible in windows 10.
2. not use build cache: Leos Literak's answer. not good solution.
3. Best solution: change build-cache path. refer to https://developer.android.com/studio/build/build-cache.html

For Ex:

in gradle.properties
android.buildCacheDir=D:/android-studio/build-cache

You can build your app cleanly. Thanks.
