Ionic build is not working after installing android studio 3.0.1

I don’t know, what I screwed up here. I am unable to run android build

sh-3.2# cordova clean android
(node:10513) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): [object Object]
(node:10513) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

My ionic info is

Did you install locally Gradle too? Since Android Studio >= 3, this is mandatory in order to build your app.


Hey @reedrichards,

Thanks, I was not knowing this. I just installed gradle and it worked well.

Thanks a lot for your help. +1

I didn’t know neither, @Sujan12 solved one of my issue by telling me to install Gradle too :wink:
