Alarms are an application independent way of fi ring Intents at predetermined times. Alarms are set outside the scope of your applications, so they can be used to trigger application events or actions even after your application has been closed. They can be particularly powerful in combination with Broadcast Receivers, allowing you to set Alarms that launch applications or perform actions without applications needing to be open and active until they’re required.
For example, you can use Alarms to implement an alarm clock application, perform regular network
lookups, or schedule time-consuming or cost-bound operations at “off peak” times.
For timing operations that occur only during the lifetime of your applications, the Handler class in
combination with Timers and Threads is a better approach as it allows Android better control over system resources.
Alarms in Android remain active while the device is in sleep mode and can optionally be set to wake
the device; however, all Alarms are canceled whenever the device is rebooted.
