We recently made a campaign for Loka mineral water, where users together reveal the new flavors. This is done by using Snapchat. We send users snaps containing puzzle pieces, and when they make a screen grab of a specific piece – we put that piece in the puzzle on the website.
Because of legal reasons we aren’t allowed to use the Snapchat API, but we still need to have some automation. For example we wanted to know immediately when a user made a screen grab of our puzzle piece snap, so we got around the problem by building an Android application.
In the latest Android SDK 4.4 (API 19) the “NotificationListenerService” was released. Using it, we can listen for incoming push notifications on our Nexus tablet. In the app, we’re just checking if the package name from the StatusBarNotification equals “com.snapchat.android” and if the notification ID matches the ID you get when someone is screenshoting your snap.
Then we post the username to our API, and cancel the notification from the NotificationListenerService.
