设备是Xoom平板电脑。出于某种原因,我无法做一个HttpPost,当我尝试时我无法捕获错误。我尝试了一堆基本的例子,它们都以同样的方式崩溃了(参见堆栈跟踪)。如果我错过了许可,我会附上我的清单。我知道它发生在client.execute(post);
声明中。错误没有被捕获,我得到的就是你在下面的堆栈跟踪中看到的。我已经尝试了一些不同的方法,但我不能为我的生活告诉真正的错误是什么。帖子数据似乎并不重要,简单的HttpGet请求也会发生同样的事情。我到底是怎么回事?

try {
HttpClient client = new DefaultHttpClient();
HttpPost post = new HttpPost("http://share1.iqperspective.com/test");
List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("avar", "test data"));
post.setEntity(new UrlEncodedFormEntity(nameValuePairs));
client.execute(post);
}catch (UnsupportedEncodingException e1) {
Log.v(TAG, "catch1");
}catch (ClientProtocolException e) {
Log.v(TAG, "catch2");
}catch (IOException e) {
Log.v(TAG, "catch3");

我认为异常的名称(NetworkOnMainThreadException
)告诉你发生了什么。您需要在非UI线程上执行网络代码。有关详细信息,请参阅文章Painless Threading。
这是Honeycomb的新功能。有关详细信息,请参阅docs for the exception。
