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...

Abstract

The invention discloses a method for detecting the pocket state of a cell phone by using an Android operating system, which is as follows: drivers of an ambient light transducer and a distance transducer are installed in the Android operating system; the operating system reads the output parameters of the ambient light transducer and the distance transducer and controls the on and off of the transducers; a pocket state detection service process is established in the Android operating system and reads the output parameters of the ambient light transducer and the distance transducer at a specified time interval; and if the output of the ambient light transducer expresses the weakest light state, and the output of the distance transducer expresses a covered state, switching to a sleep mode is executed. In the invention, the limitation that the traditional intelligent cell phone judges whether needing to be switched to the sleep mode only depending on idle over time is overcome, thereby greatly improving the standby time and usage time of Android intelligent cell phones.

Description

technical field [0001] The invention relates to the technical field of smart phones based on the Google Android operating system, in particular to a method for detecting the state of a mobile phone pocket by the Android system. Background technique [0002] Android is an open source mobile phone operating system based on the Linux kernel developed by Google. The establishment of the Open Handset Alliance (Open Handset Alliance) officially announced the birth of Android in November 2007, and it was officially put into the market in October 2008. At present, China Mobile's OPhone and its OMS (OpenMobile System) are actual products based on deep customization of Android. Android is an open source mobile phone operating system. It does not have any proprietary barriers that hindered the innovation of the mobile industry in the past. It is the first truly open and complete mobile operating system for mobile terminals. All over the world, Motorola, HTC (Dopod), Lenovo, Samsung an...
