如何解决android.os.NetworkOnMainThreadException？

时间：2014-05-24 01:13:01

标签： java c# android ksoap2

我正在使用4.0.3目标，而我正在使用kso​​ap2。 Web服务是Visual Studio 2010 Express的WCF。

可能是soap_action，call或namespace的错误。

我每次都会收到下一个错误

为什么我收到此错误？

2 个答案:

答案 0 :(得分：4)

将此代码用于活动

if (android.os.Build.VERSION.SDK_INT > 9) {
    StrictMode.ThreadPolicy policy =
       new StrictMode.ThreadPolicy.Builder().permitAll().build();
    StrictMode.setThreadPolicy(policy);
}

答案 1 :(得分：2)

Android OS不允许在主线程/ UI线程中执行繁重的进程，因为应用程序将减速，降低性能并且应用程序将滞后。

但是，您可以在AsyncTask中执行它，如下所示。在您的asyncTask的doInBackground中执行您的过程/调用您的函数。

private class Download extends AsyncTask<String, Void, String> {
    ProgressDialog pDialog;

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        Log.d("Hi", "Download Commencing");

        pDialog = new ProgressDialog(MainActivity.this);
        pDialog.setMessage("Downloading Database...");


        String message= "Executing Process";

        SpannableString ss2 =  new SpannableString(message);
        ss2.setSpan(new RelativeSizeSpan(2f), 0, ss2.length(), 0);  
        ss2.setSpan(new ForegroundColorSpan(Color.BLACK), 0, ss2.length(), 0); 

        pDialog.setMessage(ss2);

        pDialog.setCancelable(false);
        pDialog.show();
    }

    @Override
    protected String doInBackground(String... params) {

        //INSERT YOUR FUNCTION CALL HERE

        return "Executed!";

    }

    @Override
    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        Log.d("Hi", "Done Downloading.");
        pDialog.dismiss();

    }
}

并将其称为：new Download().execute("");来自另一个函数。

您可以取消进度对话框。我个人喜欢它，因为我知道我的进程将在用户可以执行任何操作之前完成（如数据加载），确保在用户与程序交互时不会发生错误。
