permission on app launch: PendingA Service is an application component that can perform long-running operations in the background, and it doesn’t provide a user interface.
Another application component can start a service, and it continues to run in the background even if the user switches to another application.
Android apps can send or receive broadcast messages from the Android system and other Android apps, similar to the publish-subscribe design pattern.
These broadcasts are sent when an event of interest occurs. For example, the Android system sends broadcasts when various system events occur, such as when the system boots up or the device starts charging. Apps can also send custom broadcasts.
With WorkManager
, developers can easily set up a task and hand it off to the system to run under the specified conditions.
A task is defined using the Worker
class. The doWork()
method is run synchronously on a background thread provided by WorkManager.
While a Worker
defines the unit of work, a WorkRequest
defines how and when work should be run. Tasks may be one-off or periodic.
