android fence

Android Fences are a mechanism that allows an application to request notification when a certain condition is met. These conditions could be anything from a geographical location to a battery level. When the condition is met, the Android system sends a notification to the app. Fences can be used to trigger actions or reminders within an app.

For example, an app could set a fence for a specific location, and when the user enters that location, the app could remind the user to complete a task related to that location. Similarly, an app could set a fence for a low battery level, and when the battery falls below that level, the app could prompt the user to charge the device.

Fences are part of the Google Play Services API, and they require location permissions to be enabled on the device. They are useful for creating location-based reminders, geofencing, and other location-based functionality in Android apps.
