Android-Sensor源码分析总结(1)

• 与Server端通信的建立过程

4，应用开发总结

1，类架构框图

如上图所示，Sensor Framework相对于Audio等模块来说，比较简单，摘录几个关键类的设计意图如下：

/**

• SensorManager lets you access the device’s {@link android.hardware.Sensor
• sensors}. Get an instance of this class by calling
• {@link android.content.Context#getSystemService(java.lang.String)
• Context.getSystemService()} with the argument
• {@link android.content.Context#SENSOR_SERVICE}.
• Always make sure to disable sensors you don’t need, especially when your
• activity is paused. Failing to do so can drain the battery in just a few
• hours. Note that the system will not disable sensors automatically when
• the screen turns off.
