我如何在Android上调试它？从Logcat下面的堆栈跟踪

Question

这是Logcat的整个堆栈。我基本上使用的是twitter4j库。我已经从twitter开发网站添加了我的令牌和秘密。 你可以帮我调试吗？ 代码主要基于http://www.androidhive.info/2012/09/android-twitter-oauth-connect-tutorial/

谢谢！

Answer 1

教导一个人捕鱼;

如果您获得Google的例外，您会注意到您无法在主线程上运行网络操作。

https://www.google.co.uk/search?q=NetworkOnMainThreadException&client=ubuntu&channel=cs&oq=NetworkOnMainThreadException&aqs=chrome.0.69i57j69i59&sourceid=chrome&ie=UTF-8

Answer 2

顶部的例外很清楚：android.os.NetworkOnMainThreadException

Android不允许您在主线程上执行网络操作。尝试创建AsyncTask并在那里进行异步操作。

Answer 3

简单你在UI线程中有一些与网络相关的代码，所以把它放在像

这样的线程中

Thread thread = new Thread()
{
@Override
public void run() {

}
};

thread.start();

与Http request或socket相关的任何代码或与网络相关的任何此类阻止UI执行的内容都会导致此异常
