Hey All,

In my project I want to add the native barcode scanner plugin.
After adding the plugin my project android build stops working.

I am running this on macOS Sierra

It throws the following error when running: ionic cordova build android

java.lang.IllegalStateException: compileSdkVersion is not specified.

And tools

When removing the plugin, the project builds succesfully.

I tried to set the defaultCompileSdkVersion to 27 in file build.gradle and search throughout the platform folder to set the CompileSdkVersion.

I do not fully understand why this error is thrown.

Can you point me in the right direction to solve this problem.

Your help is greatly appreciated.
