The invention discloses a method for acquiring a unique identifier of Android equipment, and relates to a computer technology. When the equipment unique identifier is acquired, firstly, a plurality ofpieces of key information of the Android system are acquired in an app; then according to the key information, the equipment unique identifier is constructed; the generated equipment unique identifier is stored to a plurality of positions; and finally, when the equipment unique identifier is acquired, firstly, the equipment unique identifier is acquired from storage, and if the equipment unique identifier cannot be acquired, the equipment unique identifier is regenerated. According to the invention, the equipment identifier is generated on the basis of the key information of the Android system, such as an IMEI, a Serial Number and an Android Id, so that uniqueness of the equipment identifier is ensured, and the risk of exposing information of the user equipment is avoided; and the equipment unique identifier is stored to a plurality of positions, so as to prevent a case of completely clearing up the unique identifier when the app is subjected to information clearing or unloading reinstallation and ensure stability of the unique identifier.
Description
technical field [0001] The invention relates to computer technology, in particular to a method for obtaining a unique identifier of an Android device. Background technique [0002] Android app development often encounters a scenario where a device id is needed to identify an Android device, so it is hoped to obtain a stable, reliable and unique identification code. Although the device identification code is provided in the Android system, due to too many versions of the popular Android system, devices from different manufacturers, and no unified standard, the stability and uniqueness of the device identification code are not ideal. There is no method in the Android system that can reliably obtain the unique ID of all manufacturers' devices. [0003] At present, three methods are mostly used in the development of Android device identification codes: [0004] 1. Simply randomly generate a globally unique identifier UUID in the app, which is guaranteed to be unique to all mac...
