Error with AdMob Free Plugin

When installing this plugin in combination with AdMob Free 'ionic cordova build android' the process throws the following error.

This error is clearly introduced by the combination of the two plugins. I checked this in a fresh ionic project where I only installed these two plugins and got the same error.

I did find this issue which seems to have a similar problem (#387). Removing the following two lines from plugin.xml in this repo did not solve the error though.

<framework src="com.google.gms:google-services:+" />
<framework src="com.google.android.gms:play-services-tagmanager:+" />

downgrading version of AdMob plugin resolved my issue
remove old admob plugin then
ionic cordova plugin add cordova-plugin-admob-free@0.12.1

Try installing https://github.com/dpa99c/cordova-android-support-gradle-release or https://github.com/dpa99c/cordova-android-play-services-gradle-release to fix the gradle build
