Embodiment Construction
[0024] The specific implementation process of this embodiment is as follows:
[0025] 1) Install the driver of the ambient light sensor and the distance sensor in the Android operating system
[0026] The Android operating system uses a modified Linux kernel. According to the specific hardware configuration of the mobile phone, it is necessary to install the corresponding driver module of the ambient light sensor and the distance sensor in the kernel; after the driver module is successfully installed, the operating system can read The output parameters of the ambient light sensor and the distance sensor, and can control the opening and closing of the sensor. This step is the first step of the overall flowchart.
[0027] Take the HTC Desire smart phone as an example, the ambient light sensor and the distance sensor of the Capella CM3602 chip are used in the hardware, the driver source code or binary kernel module of the sensor is added to the device directory of the source cod...
