Remarks
Return information about who launched this activity. If the launching Intent contains an android.content.Intent#EXTRA_REFERRER Intent.EXTRA_REFERRER, that will be returned as-is; otherwise, if known, an Intent#URI_ANDROID_APP_SCHEME android-app: referrer URI containing the package name that started the Intent will be returned. This may return null if no referrer can be identified -- it is neither explicitly specified, nor is it known which application package was involved.
If called while inside the handling of #onNewIntent, this function will return the referrer that submitted that new intent to the activity. Otherwise, it always returns the referrer of the original Intent.
Note that this is <em>not</em> a security feature -- you can not trust the referrer information, applications can spoof it.
