I decompiled Ring's android apk and found this this activity (launched in landscape) which appears relevant to pulling up the app to get a live view:
<activity android:name="com.ringapp.ui.activities.LiveViewLoadingActivity" android:screenOrientation="landscape" android:theme="@android:style/Theme.NoTitleBar.Fullscreen"/>
How does one craft the url schema to call this activity? e.g.
Customer support service by UserEcho
