Android Quests were a feature that utilized the Google Play Store, making it Android-exclusive. They were timed quests that only allowed you several days to complete. Completion yielded various rewards.
Since an update in the past (if you know which one, please edit it in), this feature has been discontinued. It is not present in the current version of Egg Inc.
