Alarm Manager manages the hardware clock.
Some time-related applications, such as calendars and alarms, need to use alarm Manager Services. The alarm manager function is relatively simple, and the relevant code is located inFrameworks/base/CORE/JNI/Server/com_android_server_alarmmanagerservice.cppFrameworks/base/services/Java/COM/Android/Server/alarmmanagerservic

Alarm is an independent method of triggering intent at a predetermined time.Alarm are outside the scope of the application, so they can be used to trigger application events or actions even after the application is closed. In combination with broadcast receiver, they can become particularly powerful and can be set up alarm to launch applications or perform actions, and applications do not need to be open or
Open the engine: The main alarm host used in China is vista120/ds7400 and other hosts. The related alarm software is expensive and has complicated functions. Most of the functions are unavailable for hundreds of years, non-professionals are also difficult to use all functions, especially the lack of debugging tools. Therefore, the communication protocol format of the ds7400
Speaking of wireless, everyone will think of mobile. However, there is also a device that has been used as a wireless fixed-line phone. I believe it is not a stranger to everyone. As the name suggests, wireless fixed-line Alarms can also be imagined as functions and functions. The following is a brief introduction.
Wireless fixed-line telephone, commonly known as "wireless" or "Mobile landline", is the appearance of ordinary telephones. Its core technology uses mobile communication systems, and
The new mobile phone requires an alert clock in the shutdown state. When I first started to access android, I wondered why android does not support some features in the shutdown state? Even though the drivers on each platform are different, the upper-layer applications can provide unified interfaces. In fact, they support shutdown and charging at 4.0, the shutdown alarm is not supported by default. Many brand mobile phones on the market do not support
