Android http连接异常
提问于 2011-08-08 06:48:05
我的Android3.1模拟器有一些问题。我拿不到我的XML文件。
protected InputStream getInputStream() {
try {
return feedUrl.openConnection().getInputStream();
} catch (IOException e) {
throw new RuntimeException(e);
}
}下面是错误跟踪：

使用异步任务或
if (android.os.Build.VERSION.SDK_INT > 9)
{
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

你有没有
<uses-permission android:name="android.permission.INTERNET" />在你的Android Manifest里？它应该在你的application标签上面

只有针对Honeycomb SDK或更高版本的应用程序才会引发此异常。您的sdk目标可能是api级别11或更高。只需将其更改为api级别8或11以下的其他api级别。您的问题可能会得到解决
Here也是同样的问题，它通过改变接口级别解决了这个问题。
我希望这对你有帮助。！！
