添加使用-SDK领域机器人会在清单文件会导致崩溃(Adding the uses-sdk field

出于某种原因，在Android的清单文件中添加使用-SDK字段时会导致崩溃。我已经没有这种情况发生前，但我不能让现在摆脱它。

清单文件的相关部分如下：

android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="15" />

<uses-permission android:name="android.permission.INTERNET"/>

<application

移动上述许可线，或低于用途-SDK子句都没有区别，也没有改变的最小或目标版本。无论选择什么（在合理范围内，因为我不能回去API 8，或10，或任何真正的早期水平）的应用程序崩溃，如果使用-SDK条款是在文件中。

删除它允许它运行。

我得到的错误是“不幸的是[应用]已停止”默认并有相关的“致命异常：主要”在logcat中上市的错误。

任何帮助或建议表示赞赏。

谢谢！

这是一本书，我通过工作（或试图我应该说）的例子。 :)

我加入了完整的logcat下面的清单。

Answer 1:

该错误NetworkOnMainThreadException与ICS开始，你不能在主线程上的任何网络接入。你或许应该使用AsyncTask ，你做网络接入。

Answer 2:

作为@Sameer说，你在你活动的核心做网络电话。你不应该这样做。是用于UI的一个：您的活动的所有代码的主线程上运行。你不应该作出该线程任何繁重的计算：它需要的资源远离UI，使其滞后。因为你没有用户界面被阻止的响应，只要：HTTP调用更是雪上加霜。

实现一个的AsyncTask您的网络电话。
