Testing a fresh react-native project: react-native init

Though the build succeeds but this warning is driving me crazy, any idea?

RN: v0.18.1 OS: Mac 10.11.3

Thanks!

Got rid of the warning by updating the build gradle version in build.gradle file.

Change

classpath 'com.android.tools.build:gradle:1.3.1'

To

classpath 'com.android.tools.build:gradle:1.5.0'
