Android的HttpPost崩溃，不能调试？ [英] Android HttpPost Crash, Can't Debug?
问题描述
设备是Xoom的平板电脑。出于某种原因，我不能做HttpPost，当我尝试我不能捕获的错误。我尝试了一堆基本的例子，他们都折戟以同样的方式（见堆栈跟踪）。我会附上我的表现的情况下，我错过了许可。我知道，这是发生在 client.execute（岗位）; 语句。该错误是不困，所有我得到的是什么，你在下面的堆栈跟踪看看。我已经尝试了一堆不同的方式，但我不能为我的生活跟真正的错误是什么。 POST数据似乎并不重要，同样的事情发生了简单的HTTPGET请求。在地球上我缺少什么？

我觉得异常（ NetworkOnMainThreadException ）的名称告诉你这是怎么回事。您需要在非UI线程中执行您的网络code。请参阅文章无痛线程获取更多信息。
这是新的东西蜂窝。见异常的文档的更多信息。
Device is a Xoom Tablet. For some reason I can't do a HttpPost, when I try I can't trap the error. I tried a bunch of basic examples and they all crashed out the same way (see stack trace). I will attach my manifest in case I missed a permission. I know it's happening in the client.execute(post); statement. The error is not trapped and all I get is what you see in the stack trace below. I have tried a bunch of different ways but I can't for the life of me tell what the real error is. The post data does not seem to matter, same thing happens with a simple HttpGet request. What on earth am I missing?
Block in question
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");

I think the name of the exception (NetworkOnMainThreadException) tells you what's going on. You need to execute your networking code on a non-UI thread. See the article Painless Threading for more info.
This is something new to Honeycomb. See the docs for the exception for more info.
