Hi Team, Following Exception occur while start CallService in QB.. How can i fix this issue. Issue :Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'void com.quickblox.chat.QBVideoChatWebRTCSignalingManager.addSignalingManagerListener(com.quickblox.chat.listeners.QBVideoChatSignalingManagerListener)' on a null object reference at com.wtf.services.CallService.initQBRTCClient(CallService.java:149) at com.wtf.services.CallService.startActionsOnSuccessLogin(CallService.java:129) at com.wtf.services.CallService.access$100(CallService.java:34) at com.wtf.services.CallService$1.onSuccess(CallService.java:114) at com.wtf.services.CallService$1.onSuccess(CallService.java:110) at com.quickblox.core.helper.CommonUtils.notifyEntityCallbackOnSuccess(Unknown Source) at com.quickblox.chat.QBChatService$4.run(Unknown Source) at android.os.Handler.handleCallback(Handler.java:739) at android.os.Handler.dispatchMessage(Handler.java:95) at android.os.Looper.loop(Looper.java:148) at android.app.ActivityThread.main(ActivityThread.java:5417) at java.lang.reflect.Method.invoke(Method.java) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:726) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:616)

Hi @iosgnanavel, you should be login in chat before getVideoChatWebRTCSignalingManager, if (!chatService.isLoggedIn()) { chatService.login(QBUser user);}

[peter-haiduchyk]

this error still appears. Its randomly make crash. i also check isLoggedIn

[RomanPronin]

Hi, @petergayduchik, what version SDK do you use? Is this issue reproducible on videosample?

[peter-haiduchyk]

@RomanPronin 3.3.4 im using.

    compile 'com.quickblox:quickblox-android-sdk-chat:3.3.4'
    compile 'com.quickblox:quickblox-android-sdk-core:3.3.4'
    compile 'com.quickblox:quickblox-android-sdk-messages:3.3.4'
    compile 'com.quickblox:quickblox-android-sdk-videochat-webrtc:3.3.4'
    compile project(':quickblox-android-sdk-content-3.3.4')

this error realy randomly showing. I cant reproduce this bug. When i forgot about this error - error come to my head -_- java.lang.NullPointerException: Attempt to invoke virtual method 'void com.quickblox.chat.QBVideoChatWebRTCSignalingManager.addSignalingManagerListener(com.quickblox.chat.listeners.QBVideoChatSignalingManagerListener)' on a null object reference

on line

QBChatService.getInstance().getVideoChatWebRTCSignalingManager()
                    .addSignalingManagerListener(new QBVideoChatSignalingManagerListener() {
                        @Override
                        public void signalingCreated(QBSignaling qbSignaling, boolean createdLocally) {
                            if (!createdLocally) {
                                QBRTCClient.getInstance(context).addSignaling((QBWebRTCSignaling) qbSignaling);
                                Logger.d("add signalling ");
                            }
                        }
                    });

here .addSignalingManagerListener(new QBVideoChatSignalingManagerListener() {

before i see this error in logcat - its take to time. Like app loading... bla bla errors also here

org.jivesoftware.smack.SmackException$ConnectionException: The following addresses failed: 'chat.quickblox.com:5223' failed because java.net.SocketTimeoutException: failed to connect to chat.quickblox.com/34.192.242.204 (port 5223) after 30000ms

sure its can be internet access problem. I just cant reproduce. Everything what i have - i show here.

[RomanPronin]

If you successfully logged in to chat, before addSignalingManagerListener(), and still have a issue, in that case, I can offer you to check qbVideoChatWebRTCSignalingManager != null, before adding listener, to avoid NullPointerException.

[islavstan]

Hello! I have the same issue. I use your sample-videochat-webrtc. In CallService

private void loginToChat(QBUser qbUser) { chatService.login(qbUser, new QBEntityCallback() { @Override public void onSuccess(QBUser qbUser, Bundle bundle) { Log.d(TAG, "login onSuccess"); startActionsOnSuccessLogin(); }

        @Override
        public void onError(QBResponseException e) {
            Log.d(TAG, "login onError " + e.getMessage());
            sendResultToActivity(false, e.getMessage() != null
                    ? e.getMessage()
                    : "Login error");
        }
    });
}

method startActionsOnSuccessLogin call only after success login. In method initQBRTCClient()

private void initQBRTCClient() { rtcClient = QBRTCClient.getInstance(getApplicationContext()); // Add signalling manager if (chatService != null && chatService.getVideoChatWebRTCSignalingManager() != null) { chatService.getVideoChatWebRTCSignalingManager().addSignalingManagerListener((qbSignaling, createdLocally) -> { if (!createdLocally) { rtcClient.addSignaling((QBWebRTCSignaling) qbSignaling); } }); } // Configure QBRTCConfig.setDebugEnabled(true); SettingsUtil.configRTCTimers(CallService.this);

    // Add service as callback to RTCClient
    rtcClient.addSessionCallbacksListener(WebRtcSessionManager.getInstance(this));
    rtcClient.prepareToProcessCalls();
}

I add two check for null, but this did not solve the problem

In your library I have problems only with WebRTCSignalingManager, please check

[tatanka987]

@islavstan please provide full log from start login to the chat to getting this error for better understanding your issue (chat's logs must be enabled QBChatService.setDebugEnabled(true);)
