| 41 | * This class provides access to the system alarm services. These allow you |
| 42 | * to schedule your application to be run at some point in the future. When |
| 43 | * an alarm goes off, the {@link Intent} that had been registered for it |
| 44 | * is broadcast by the system, automatically starting the target application |
| 45 | * if it is not already running. Registered alarms are retained while the |
| 46 | * device is asleep (and can optionally wake the device up if they go off |
| 47 | * during that time), but will be cleared if it is turned off and rebooted. |
Chris Tate | a34df8a2 | 2009-04-02 23:15:58 -0700 | [diff] [blame] | 48 | * |
| 49 | * <p>The Alarm Manager holds a CPU wake lock as long as the alarm receiver's |
| 50 | * onReceive() method is executing. This guarantees that the phone will not sleep |
| 51 | * until you have finished handling the broadcast. Once onReceive() returns, the |
| 52 | * Alarm Manager releases this wake lock. This means that the phone will in some |
| 53 | * cases sleep as soon as your onReceive() method completes. If your alarm receiver |
| 54 | * called {@link android.content.Context#startService Context.startService()}, it |
| 55 | * is possible that the phone will sleep before the requested service is launched. |
| 56 | * To prevent this, your BroadcastReceiver and Service will need to implement a |
| 57 | * separate wake lock policy to ensure that the phone continues running until the |
| 58 | * service becomes available. |

| 60 | * <p><b>Note: The Alarm Manager is intended for cases where you want to have |
| 61 | * your application code run at a specific time, even if your application is |
| 62 | * not currently running. For normal timing operations (ticks, timeouts, |
| 63 | * etc) it is easier and much more efficient to use |
