1) 得到传感器服务 getSystemService(SENSOR_SERVICE); 得到一个SensorManager,用来管理分配调度处理Sensor的工作,注意它并不服务运行于后台,真正属于Sensor的系统服务是SensorService,终端下#service list可以看到sensorservice: [android.gui.SensorServer]。 2) 得到传感器类型 getDefaultSensor(Sensor.TYPE_GRAVITY); 当...

.getDefaultSensor(Sensor.TYPE_LIGHT) 使用SensorManager.registerListener方法设置传感器监听SensorEventListener,注意在界面停止和恢复时重新设置和取消监听。第一个参数为传感器监听,第二个参数为具体需要监听的传感器实例,第三个参数为感应器的敏感度,在Android中提供了四种延迟级别分别为 SENSOR_DELAY_FASTEST 最低延迟 0...

With UEFI boot enabled in this release, the plugin-manager is no longer supported. Now, you need to create a device-tree overlay file to register the camera module. If your camera module has on-board EEPROM and is programmed with a valid camera ID, you can use that to app...
