Adding meta-data to AndroidManifest

I would like to add this meta-data to my <application> in the AndroidManifest.

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>

You should be able to use AndroidManifest.ApplicationElement like in my reply here.

By the way, if you want to find this kind of stuff yourself, you can look at the files that we use to generate project files like AndroidManifest.xml. If you search for the file in your Uno dir (on my machine this is /usr/local/share/uno/), you’ll find the file which will contain some things like @(AndroidManifest.ApplicationElement:Join('\n')).
