我有以下两个用于 Pax 库的库

    implementation files('libs/PaxGLPage_V1.00.04_20170420.jar')
    implementation files('libs/PaxNeptuneLiteApi_V2.00.01_20170527.jar')

在我的活动中,我设法启动了库,如下所示:

        //Get the entity of printer.
        neptuneLiteUser = NeptuneLiteUser.getInstance();
        try {
            dal = neptuneLiteUser.getDal(this.getApplicationContext());
        } catch (Exception e) {
            e.printStackTrace();
            Log.d("getDal", e.toString());
        }

        paxGLPage = PaxGLPage.getInstance(this.getApplicationContext());

我成功在 A920 设备上运行打印机

但是,我无法运行 Mifare Card Reader (Contactless Card) 有什么方法可以运行吗?
