通过 POST 请求发送数据时崩溃答案

【问题标题】：Crash on sending Data though POST request通过 POST 请求发送数据时崩溃
【发布时间】：2014-11-06 07:42:43
【问题描述】：

我是 Android 新手，所以请耐心等待:)

我需要将用户输入的数据发送到我们的数据库 (CRM)。当用户点击提交按钮发送数据时会崩溃。

当我将函数 postDataForOrenG() 放在 OnClick() 中时，它会崩溃，当我不把它 ("//postDataForOrenG()") 时，它会毫无问题地转到其他活动。

请在下面找到我的代码和 LogCat 中的错误。

非常感谢您的帮助:))

【问题讨论】：

你好像没有给Manifest文件添加权限
哦，谢谢！我在清单中添加了蓝牙权限。我再次运行我的应用程序，它再次崩溃。请从我的 logCat 中查看日志，我再次对其进行编辑。

【解决方案1】：

缺少蓝牙权限！

这是你的错误。在清单中添加蓝牙访问权限。

"android.os.NetworkOnMainThreadException" 是罪魁祸首。您的方法“postDataForOrenG()”应在 UI 外调用，即所有网络请求和长时间运行的任务都应在 UI 外调用，搜索 AsyncTask 或 Thread 和 Handler 组合以进行网络调用。
好的，非常感谢！我理解一般概念。我怎样才能在我的代码中做到这一点？请帮助我处理你告诉我的非 UI 线程

哦，谢谢，我在 Vogella 的示例中看到他使用的是 Get 请求，我使用的是 Post 请求。像我在 Vogella 的例子中看到的那样，尝试使用 Get 请求对我来说更好吗？
