我的应用程序通过 WiFi 运行.但在android中不超过3G?有什么猜测吗? [英] My App works over WiFi. But not over 3G in android? Any Guesses?

问题描述

我开发了一个目标版本为 4 (Android 1.6) 到 7 (Android 2.1) 的应用程序.我在开发手机 2(Google-Io-Device 1.6 版本)上测试了这个应用程序.我正在通过 Internet 进行一些 xml 解析.我在我的清单上设置了 <uses-permission>.它在 WI-FI 网络中运行良好.但它不适用于带有 3G 网络的 Motorola Droid 2.1.3G网络还有什么更具体的事情要做吗?任何的想法?

I have developed an App that target version is 4 (Android 1.6) upto 7 (Android 2.1). I tested this app on the dev phone 2 (Google-Io-Device 1.6 version). I am doing some xml parsing stuff through Internet. i set the <uses-permission> on my Manifest. it works fine in WI-FI Network. But its not working in the Motorola Droid 2.1 with 3G Network. Is there any more specific stuff to do for 3G network? Any Idea?

推荐答案

仅限android.permission.INTERNET.如果您要连接的服务器位于路由器/防火墙后面，则很可能只能从您的本地网络访问该服务器.一个简单的测试是尝试在系统浏览器应用中打开您尝试访问的相同 URL.

Only android.permission.INTERNET. It's most likely that the server you're connecting to is only accessible from your local network, if it's behind a router/firewall. An easy test is to try to open the same URL you're trying to hit in the system Browser app.

从 logcat 查看回溯也很有帮助.

It'd also be helpful to see the traceback from logcat.
