C297 is a task in the Tasker application for Android. It is used for automatically performing tasks such as launching an app, changing settings, or sending a text message. Tasker is an automation app that allows users to create automated tasks, or “tasks” based on criteria that they set. The C297 task, in particular, can be used to launch any app, setting or task when certain criteria are met. This criteria can be time, location, or even other tasks. For example, it can be used to turn on Wi-Fi when you arrive at home, or to launch Spotify when you plug in headphones. With Tasker, the possibilities are nearly limitless.
