QUESTION
I have been following a chat bot tutorial and am stuck. I have included the exact step that I am on as a link at the bottom of this post in case you are curious what my code looks like (I was frustrated so I copied his code word for word).
During the execution of my code, it processes just over 26,000 lines before it throws the exception. My code can be found below. As you can see, I have tried various solutions including replacing /r and /n characters with nothing and adding the tag strict=False
which should allow unterminated strings into the json, but that didn't work either.

Answered 2018-Mar-14 at 18:14As I explained in EDIT2, I printed out the line that was giving me trouble, and saw that it did not end in a }
, which every JSON Object should. I then went into the file, and checked the exact line that was giving me trouble by using a simple search, and I found that the line was not only truncated, but it was also the last line of my file as well.
There was definitely an error when I was either downloading or extracting this file, and it seemed to cut it short. This in turn threw the error that I got with no solution seeming to work.
To anyone who is having this error and .replace() solutions are not working: try to look through your data and make sure that there is in fact something there to replace or edit. In my case there was a truncating error during the download or extraction which made such solutions impossible.

QUESTION
I'm building an app where there are two types of users: passengers and drivers. I am adding a chat interface to the app. The users are sending and receiving the messages. However, they appear on the same side, and the username is not displaying above the message. I need the sender's messages to be on the left side while the received messages are on the right side. I've looked at a lot of tutorials for chat apps, but I can't find one that will fix my problem. I used the following tutorial to get where I am now: https://github.com/mehulmpt/ionic-firebase-chat

QUESTION
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):

I am fairly new to Firebase as well as angular2. So I am trying to make a Firebase integrated angular2 Chat app through tutorials.
