1.先申请权限，关于如何申请权限请查看RxPermissions的使用（简单实用）_ErwinNakajima的博客-CSDN博客
2.手機唯一識別碼管理類。

4.獲取系統數據。
//手机厂商SystemManager.getDeviceBrand();//手机型号SystemManager.getSystemModel();//手机当前系统语言SystemManager.getSystemLanguage();//手机系统版本号SystemManager.getSystemVersion();//手机CPU架构SystemManager.getDeviceCpuAbi();//手機唯一識別碼SystemManager.getSystemId(mContext.getApplicationContext());

推荐Android开源项目
项目功能介绍：RxJava2和Retrofit2项目，添加自动管理token功能，添加RxJava2生命周期管理，使用App架构设计是MVP模式和MVVM模式，同时使用组件化，部分代码使用Kotlin，此项目持续维护中。
