Add you this repo and your ad unit ID to your manifest.json
.
{
"dependencies": {
"admob": "https://github.com/hashcube/admob.git#master"
},
"android": {
"admobAdunitID": "ca-app-pub-xxx/xxx"
}
}
Note: In dependecies it is better to use the latest version tag instead of the branch name. eg: replace #master to #v1.0.1
