Android 获取手机系统版本号、获取手机型号、获取手机厂商、获取手机IMEI、获取手机CPU

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。

    }

    
    public static String getSystemId(Context context) {
        return SystemIdManager.getSystemId(context);
    }

    
    public static String getDeviceUUid() {
        String androidId = DeviceUtils.getAndroidID();
        UUID deviceUuid = new UUID(androidId.hashCode(), ((long) androidId.hashCode() << 32));
        return deviceUuid.toString();
    }

}

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。
