我想知道如何在外部设备上模拟我的Android应用，以便与在我的机器上运行的本地API服务器进行通信。
该应用正在使用cordova并使用USB连接在Android设备上运行。我在本地运行API服务器。
使用我机器的IP地址，我试图通过应用程序内的HTTP调用与API服务器通信。但是我在调试器中遇到404错误。
POST http://myIP:8083/api/login 404 (Not Found)
API服务器正在运行且可访问。我通过设备的网络浏览器访问它确认了它。我的预感是我必须在某处将我的IP列入白名单。但我不确定。有什么建议吗？
使用Cordova 5.3.3。在LGE Nexus 5 Android 4.4.4（API 19）上进行测试。
