static openURL(url)
Starts a corresponding external activity for the given URL.
For example, if the URL is "https://www.facebook.com", the system browser will be opened, or the "choose application" dialog will be shown.
You can use other URLs, like a location (e.g. "geo:37.484847,-122.148386"), a contact, or any other URL that can be opened with {@code Intent.ACTION_VIEW}.
NOTE: This method will fail if the system doesn't know how to open the specified URL. If you're passing in a non-http(s) URL, it's best to check {@code canOpenURL} first.
NOTE: For web URLs, the protocol ("http://", "https://") must be set accordingly!
