OverviewSometimes the user device needs to be identified, so you want to get a stable and reliable and unique identification code. Although such device identifiers are available in the Android system, stability and uniqueness are not ideal due to limitations such as the Android version and bugs in the vendor-specific system. And through other hardware information identification also because of the system version, mobile phone hardware and other
