Updated from Android Studio 1.4 to 2.0, and had the IDE change my gradle dependency to 2.0 from 1.x in the build.gradle:
Gradle sync failed: Can't load library: C:\Users\foobar\.gradle\native\19\windows-amd64\native-platform.dll
Consult IDE log for more details (Help | Show Log)
Remove the "native" folder from gradle path:
When run again, it will regenerate the "native" folder, and the associative .dll.
