Solved :

Go to android studio configuration. SDK Platforms must have API level 23 checked (I had that). But that’s not enough. Go to SDK Tools, then check Show Package Details, expand the Android SDK Build-Tool 25 (or whatever version number) and make sure the 23.0.0 is checked. Even if it says it is obsolete.

The guide mention this :

Make sure to select SDK Platform API 23, because that is what the version of Cordova we bundle requires.

But says nothing about the Hidden package detail in the SDK Build-Tools. Since (let’s be honest) a fair share of us knows very little to nothing about native development and building, this would be worthy of a short mention in the guide.
