Android Honeycomb:即使在使用 AsyncTask 且没有严格模式时，NetworkOnMainThreadException 也是如此? [英] Android Honeycomb: NetworkOnMainThreadException even when using AsyncTask and no strict mode?

问题描述

我的 Android 3.0 应用程序遇到了 NetworkOnMainThreadException.在寻找解决方案时，我发现了 this，但如果我理解正确，默认设置将是关闭严格模式.

I run into a NetworkOnMainThreadException with my Android 3.0 app. Searching for a solution I found this, but if I understand this correctly, default setting would be that the strict mode is turned off.

此外，我所有的网络访问都在 AsyncTask 中，所以无论如何我都看不到这个异常的意义.

Also, all my network access is in an AsyncTask, so I don't see the point in this Exception anyway.

所以，我现在很绝望我应该做些什么来防止这种情况发生...

So, I'm quite desperate now what I should do to prevent this...

亲切的问候，水母

这篇博客文章说AsyncTask 应该足够了，但至少阐明了 StrictMode 点.

This blog entry says that AsyncTask should be enough, but at least clarifies the StrictMode point.

解决方案:

我关闭了 StrictMode(保留一些设置可能更好，但我不会被打扰...):

I turned off the StrictMode (its probably better to keep some settings but I couldn't be bothered...):

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);

在那之后，我确实遇到了java.lang.RuntimeException:This thread forbids HTTP requests"，但找到了解决方案此处.不过，我有点困惑，因为 AndroidHttpClient 在我的 Android 2.0+ 应用程序中使用它时运行良好......

After that, I did run into a "java.lang.RuntimeException: This thread forbids HTTP requests", but found a solution for this here. I'm a bit confused, though, as AndroidHttpClient worked fine when I used it in my Android 2.0+ app...

解决方案，第 2 部分

事实证明，使用 AsyncTask 是个好主意，但如果 做错了...所以严格模式的反应没有任何问题.应该听过吧?;)

As it turned out, using AsyncTask was a nice idea but pretty useless if done wrong... So there was nothing wrong with the strict mode's reaction. Should have listened, er? ;)

知道它默认在 Honeycomb 上激活还是很高兴的.

Still good to know it's activated on Honeycomb by default.

推荐答案

StrictMode 在 Honeycomb 中默认开启.

StrictMode is turned on by default in Honeycomb.

具体参见 链接penaltyDeathOnNetwork().我遇到了类似的问题.

See say link specifically penaltyDeathOnNetwork(). I ran into a similar problem.
