问题描述
我使用的是Android的Facebook SDK进行后期在Facebook wall.I已经使用下面的$ C $下的墙后,但通过例外每次 android.os.NetworkOnMainThreadException
公共无效postToWall(字符串消息){
捆绑参数=新包();
parameters.putString(消息,消息);
parameters.putString(说明,主题股);
尝试 {
facebook.request(我); //这里出错
字符串响应= facebook.request(ME /饲料,参数,POST);
Log.d(测试,得到了回应:+响应);
如果(响应==空|| response.equals()
|| response.equals(假)){
showToast(空白回应。);
} 其他 {
showToast(消息发布到你的Facebook墙上!);
}
完();
}赶上(例外五){
showToast(无法张贴到墙上!);
e.printStackTrace();
完();
}
}
的logcat

解决方案
编辑:另一种想法,但是这是不好的。它是用不好的做法,但有些人使用它。
StrictMode.ThreadPolicy政策=新StrictMode.ThreadPolicy.Builder()permitAll()建立()。;
StrictMode.setThreadPolicy(政策);
上面添加code。在您的活动类。
我个人preFER第一个选项使用线程或AsyncTask的。
I'm using Android facebook SDK for post on facebook wall.I have used following code for wall post but every time through exception android.os.NetworkOnMainThreadException
public void postToWall(String message) {
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me");//Error here
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("")
|| response.equals("false")) {
showToast("Blank response.");
} else {
showToast("Message posted to your facebook wall!");
}
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}

解决方案
Edit : Another Idea but it is not good . It is Bad Practice to use it but some people use it.
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Add above code in your activity class.
I personally Prefer the first option use thread or AsyncTask .
