Question

我在堆栈中读了很多分辨率，但我无法解决这个问题。

我给我的应用程序互联网预先
我使用asynctask
我的问题是一样的。如果我开始构建

我尝试用try catch来做。我也尝试用预期的抛出来做但没有任何帮助。我希望有一位能帮我解决这个问题的专家。没有Builder，应用程序运行正常没有问题

MainActivity.class

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        connectXmpp con= new connectXmpp();
        con.execute();
    }
}

connectXmpp.class

import android.os.AsyncTask;


import org.jivesoftware.smack.ConnectionConfiguration;
import org.jivesoftware.smack.tcp.XMPPTCPConnection;
import org.jivesoftware.smack.tcp.XMPPTCPConnectionConfiguration;

/**

public class connectXmpp extends AsyncTask <Void,Void,Void>{
    public static XMPPTCPConnection connection;
    @Override
    protected Void doInBackground(Void... voids) {


        XMPPTCPConnectionConfiguration.Builder config = XMPPTCPConnectionConfiguration
                .builder();
        config.setUsernameAndPassword("username","pw");
        config.setSecurityMode(ConnectionConfiguration.SecurityMode.disabled);
        config.setHost("dismail.de");
        config.setPort(5222);
        config.setDebuggerEnabled(true);
        XMPPTCPConnection.setUseStreamManagementDefault(true);
        connection = new XMPPTCPConnection(config.build());

        return null;
    }

    @Override
    protected void onProgressUpdate(Void... values) {
        super.onProgressUpdate(values);
    }

    @Override
    protected void onPostExecute(Void aVoid) {
        super.onPostExecute(aVoid);
    }



}

好吧好像smack 4.2有一个bug。使用此依赖项解决了我的问题：

compile 'org.igniterealtime.smack:smack-android:4.1.1'
   compile 'org.igniterealtime.smack:smack-android-extensions:4.1.1'
   compile 'org.igniterealtime.smack:smack-core:4.1.1'
   compile 'org.igniterealtime.smack:smack-tcp:4.1.1'
   compile 'org.igniterealtime.smack:smack-extensions:4.1.1'
   compile 'org.igniterealtime.smack:smack-experimental:4.1.1'
   compile 'org.igniterealtime.smack:smack-resolver-minidns:4.1.1'
   compile 'org.igniterealtime.smack:smack-sasl-provided:4.1.1'
   compile 'org.igniterealtime.smack:smack-im:4.1.1'
   compile 'org.jxmpp:jxmpp-core:0.4.2-beta1'
   compile 'org.jxmpp:jxmpp-util-cache:0.4.2-beta1'
   compile 'de.measite.minidns:minidns:0.1.1'

咂4.2。如果我建立连接，应用程序总是崩溃
