The contacts info can only be got in the android apps, so you have to write an android app and a pc app, and transfer data between them. 联系人信息只能在android应用中获取，因此您必须编写android应用和pc应用，并在它们之间传输数据。

When a device is connected to pc, start your pc app automatically. 将设备连接到PC后，将自动启动PC应用程序。
Install your android app to the device. 将您的android应用安装到设备上。
