连接到本地网络服务时Android应用程序崩溃[重复]答案

【问题标题】：Android app crashes when connecting to webservice LOCAL [duplicate]连接到本地网络服务时Android应用程序崩溃[重复]
【发布时间】：2013-10-17 10:42:13
【问题描述】：

我从 Android 客户端连接到我的网络服务时遇到问题。在我的 MainActivity 类中，程序在第 66 行崩溃：

transporte.call(accionSoap, sobre);

我认为问题可能出在 accionSoap 上，非常感谢任何帮助。

您需要使用 asynctask 来处理 Web 服务调用，

    getMenuInflater().inflate(R.menu.main, menu);
    return true;

public void onClickLogin(View view){

    new ServiceCallTask().execute();
}

class ServiceCallTask extends AsyncTask<String, String, String>

    @Override

仍然无法正常工作，已将新日志添加到您的解决方案中
@user2887592 更改此代码后，您是否会遇到相同的错误或其他错误。请为该代码添加更新的代码和 logcat。您在 MainActivity.java:75 行有什么代码
我认为是一样的，你可以看到新的日志。第 75 行是 transporte.call(accionSoap, sobre);
stackoverflow.com/questions/19431456/…

【解决方案2】：

android.os.NetworkOnMainThreadException

您正在主线程中运行不允许的网络操作，请在另一个线程中执行该操作。

要么使用AsyncTask 并在doInBackground 方法中调用，要么创建new Thread() 并在run 方法中调用。
