kandi X-RAY | chatEx Summary

chatEx is a JavaScript library typically used in Networking, Websocket, Nodejs applications. chatEx has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

After launching the node server, users can access the system through their web browser. Once loaded, the web page should never need to reload. The user should enter their name and be able to start chatting immediately. They should see a list of all users in the chat room, and be able to type messages in a box by typing and pressing enter. A list of chat messages should also be displayed. It is only necessary to show chat messages that were sent after the user has logged in (i.e. no history storage is necessary). The messages should be sent over websockets as "push" notifications. That is, there should be no polling at all, as soon as a message is typed by one user it should show up on all other logged in users screens instantly. On the front-end, only one HTML page is required with inline CSS and Javascript, this HTML file should be served by the node.js script. The node.js script should also handle all websocket communication. Must be launchable by "node script.js " node.js must also be the web server and handle the web sockets with socket.io.

application crashes during the first launch while using FirebaseAuthentication

QUESTION

application crashes during the first launch while using FirebaseAuthentication

Asked 2018-Jan-19 at 16:31

I've been starting to learn android since past few months. I'm creating a very basic chat application that uses Firebase Authentication, Firebase realtime database and Firebase Storage. I have used Lapit Chat Application YouTube tutorial and its source code in GitHub as the reference.

My application has MainActivity as the launcher activity, where the Firebase Authentication checks whether authentication is successful or not. If not, user is navigated to StartActivity (where user can login or register a new account). MainActivity has two fragments, namely ChatsFragment and FriendsFragment, which can be slided to navigate to each other (ViewPager is used).

Problem: The app crashes at startup when launched for the first time. After showing 'Unfortunately ChaTeX has stopped' and pressing okay, the app then launches, and everything works fine.

I am currently testing this application in Android Marshmallow in two devices where I get the same error in both devices. But the application doesn't launch at all in Nougat devices and the app keeps crashing all the time. What I guess is that the cause of error in both the android versions is same.

Logcat shows java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String com.google.firebase.auth.FirebaseUser.getUid()' on a null object reference in the onCreateView method of ChatFragments.java as shown in the snippet below(The line where I get Error is commented):

ChatsFragment.java:
