Android XMPP连接不是持久性的-asmack库甚至在单独的线程中运行
[英]Android XMPP connection is not persistant - asmack library even running in a separate thread
问题描述
我正在开发一个使用asmack库的Android聊天应用程序。 我观察到XMPP连接在特定时间间隔后断开连接。 （这也因设备而异）
我正在按照以下链接中的说明在单独的线程中运行连接代码
但我得到以下异常
D/Reconnection Manager(23105): scheduleReconnect: calling tryToConnect
I/System.out(23105): default ping interval is :10

不知道我要去哪里错了。 我从许多SO问题中了解到，在单独的线程中进行连接/重新连接是可行的。 但是对我来说没有发生...
下面是我正在使用的代码块
在下面，我最初连接到XMPP服务器，一切正常
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
.......
startXmppThread();
.......
}
下面的代码块是我启动XMPP线程的地方
public void startXmppThread(){
isConnecting = true;
SmackAndroid.init(ChatService.this);
PingManager.setDefaultPingInterval(10);
SmackConfiguration.setDefaultPacketReplyTimeout(20000);
if(xmppThread == null){
xmppThread=new Thread(xmppRunnable,"connection thread");
xmppThread.start();
}
}
XMPP可运行代码
Runnable xmppRunnable = new Runnable() {
@Override
public void run() {
Log.d(TAG,"starting now thread :"+Thread.currentThread().getId()+" : "+Thread.currentThread().getName());
Looper.prepare();
try{
connectToXmppServer();
handler.post(mRunnableConnectionMonitor);
}catch (Exception e) {
//handler.removeCallbacks(mRunnableConnectionMonitor);
Log.d(TAG, "Trying to Reconnect from the run catch exception");
scheduleReconnect();
e.printStackTrace();
}
xyzz = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(android.os.Message msg) {
switch (msg.arg1) {
case 1:
Log.d(TAG, "Got Message to connect again");
try {
connectToXmppServer();
handler.post(mRunnableConnectionMonitor);
} catch (Exception e) {
//handler.removeCallbacks(mRunnableConnectionMonitor);
Log.d(TAG,"Trying to reconnect from the handleMessage case 1");
scheduleReconnect();
e.printStackTrace();
}
break;
case 2:
Log.d(TAG, "Got Message to disconnect");
handler.removeCallbacks(mRunnableConnectionMonitor);
try {
connection.disconnect();
Log.d(TAG, "succesfully disconnected");
}catch (Exception e) {
Log.d(TAG, "Exception while disconnecting");
e.printStackTrace();
}
break;
case 3:
Log.d(TAG,"Trying to reconnect from the handleMessage case 3");
scheduleReconnect();
handler.removeCallbacks(mRunnableConnectionMonitor);
break;
default:
break;
}
return false;
}
});
Looper.loop();
}
};
连接到XMPP服务器的代码块
private void connectToXmppServer() throws Exception {
if(config ==null)
config = new ConnectionConfiguration(CHAT_SERVER_IP, 5222,host);
config.setSecurityMode(SecurityMode.disabled);
config.setSendPresence(true);
config.setRosterLoadedAtLogin(false);
if(connection == null)
connection = new XMPPTCPConnection(config);
if(mPingManager == null)
mPingManager = PingManager.getInstanceFor(connection);
mPingManager.unregisterPingFailedListener(mPingFailedListener);
mPingManager.registerPingFailedListener(mPingFailedListener);
System.out.println("default ping interval is :"+mPingManager.getPingInterval());
if(!connection.isConnected())
connection.connect();
if(!ConnectlinksApp.m_sharedHelper.getChatRegistration()){
String mobileID = ConnectlinksApp.m_sharedHelper.getMobileID();
Log.d(TAG, "trying to register with : "+mobileID);
AccountManager accountManager=AccountManager.getInstance(connection);
try{
accountManager.createAccount(mobileID, m_strUserPassword);
Log.d(TAG, "account created successfully"+mobileID);
}catch (Exception e) {
Log.d(TAG, "account already exist"+mobileID);
e.printStackTrace();
}
ConnectlinksApp.m_sharedHelper.setChatRegistration(true);
}
if(!connection.isAuthenticated()){
login();
}
}
代码块whicj重新连接到XMPP服务器
protected void scheduleReconnect() {
if (mReconnectHandler == null) mReconnectHandler = new Handler();
mReconnectHandler.removeCallbacks(mReconnectRunnable);
Log.d("Schedule Reconnect","scheduleReconnect: scheduling reconnect in 10 seconds");
mReconnectHandler.postDelayed(mReconnectRunnable, 10000);
}
重新连接的可运行
private final Runnable mReconnectRunnable = new Runnable() {
@Override
public void run() {
Log.d("Reconnection Manager","scheduleReconnect: calling tryToConnect");
try{
connectToXmppServer();
handler.post(mRunnableConnectionMonitor);
Log.d(TAG, "This shold be called");
}catch (Exception e) {
// handler.removeCallbacks(mRunnableConnectionMonitor);
e.printStackTrace();
scheduleReconnect();
}
}
};
我尝试了所有可能性，但未能找到解决方案。 遇到相同问题的任何人都可以帮助我。 感谢您抽出宝贵的时间阅读这篇长文章。

因此，这基本上意味着它无法识别聊天服务器，但它已启动并正在运行。
我在Ejabberd服务器中需要做任何设置吗？ 相当困惑。 PLS。 帮我。
我用来获取异常的代码是
System.out.println("This is what I am looking for beginning");
Log.e("ERROR", "ConnectionException", e);
for (int i = 0; i < e.getFailedAddresses().size(); i++) {
HostAddress element = e.getFailedAddresses().get(i);
Log.e("ERROR", element.getErrorMessage().toString());
}
System.out.println("This is what I am looking for end");
**********************编辑*************************
经过进一步调查，我知道connectToXmppServer方法在Runnable中。
Runnable xmppRunnable = new Runnable() {
@Override
public void run() {
.....
connectToXmppServer();
.....
}
}
因此，将Runnable更改为这样的线程
Thread xmppRunnable = new Thread(){
在此之后，好消息是虽然我无法解决问题（这是用户在几个小时内脱机），但我收到了一个异常，该异常指出该异常为NetworkOnMainThreadException

不知道为什么我在单独的线程中运行此异常，为什么会收到此异常。 任何指针对我来说都是非常有用的。 我希望这个SO问题将使面对该问题的所有人受益。

经过长时间的奋斗，这是我的观察，我能够找到解决问题的办法。 欢迎提供有关我的解决方案的任何反馈
编辑保留答案。
我只是将代码从Runnable修改为线程
当连接到聊天服务器的代码在Runnable中时，我收到了android.os.NetworkOnMainThreadException。 由于某种原因，我无法找到NetworkOnMainThreadException的堆栈跟踪。 使用Runnable建立连接时，ConnectionConfiguration带有NetworkOnMainThreadException。
希望这对遇到与我类似问题的人有所帮助。 我衷心感谢@Flow为帮助我解决此问题所做的努力。 您的出色工作值得称赞，这对android社区是一种祝福。
有关异常，请参见附件中的图像。

最好在代码中使用AsyncTask进行连接而不是使用Thread。不建议在Android中使用Thread.Try AsyncTask，它用于与连接相关的所有目的。
class ConnectServer extends AsyncTask<Void, Void, XMPPConnection> {
