Twitter4j在Android 4中崩溃

问题描述：

我正在尝试使用twitter4j进行Oauth进程。我查看了Android浏览器，发现互联网连接仍然在打开Google。Twitter4j在Android 4中崩溃

我运行下面的代码片段。当我在我的活动中运行此代码时，在我的模拟器页面中出现“不幸myapp已关闭”。在Logcat内部，我只看到：“ccc：trying1”。我没有看到“试2”。

可能这个错误并不是因为twitter4j，而是我找不到错误。

Twitter twitter = TwitterFactory.getSingleton(); 
    twitter.setOAuthConsumer("12345", "aaaa1212"); 
    RequestToken requestToken = null; 
    try { 
     Log.d("ccc","trying1"); 
     requestToken = twitter.getOAuthRequestToken(); 
     Log.d("ccc","trying2"); 
    } catch (TwitterException e) { 
     Log.d("unsuccess message:",e.getMessage()); 
     Log.d("unsuccess statuscode:", Integer.toString(e.getStatusCode())); 
     Log.d("unsuccess errormessage:",e.getErrorMessage()); 
     e.printStackTrace(); 
    }

应用：
的minSdkVersion = “10”
targetSdkVersion = “17”
模拟器版本的Android 4.2.2

编辑：我很好奇非异步请求可能是问题。因为相同的代码完美适用于Android 2.3.3。我得到android.os.NetworkOnMainThreadException。 logcat的条目是这样的：

你有互联网许可？ –

是的，我在清单文件中拥有该权限。 – trante

你可以发布你的整个崩溃的stacktrace？您必须让它崩溃;） –

答

您例外名字说明了一切“NetworkOnMainThreadException”

您正在主/ UI线程上的网络电话。

尝试在一个单独的线程或类似的AsyncTask执行此代码：

new Thread(new Runnable() { 
    // your code 
}).start();

编辑：Android 2.3的如果你在主线程上网不检查（为此，我们都需要离开这个版本的Android后面;））
