Failed to insert a record in the Firebase Database

Question

Alright, I am fairly new to the Firebase development and I am trying to insert a data into the app database that I have connected to my android studio project. However, I get this stack-trace after clicking a button that adds the text to the database:

E/AndroidRuntime: FATAL EXCEPTION: main
                      Process: com.xxx.xxxxx, PID: 13243

                          at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:698)

And the MainActivity code line that if bursts on aka line 85 is as follows:

mDatabase.child("users").child(mUserId).child("items").push().child("title").setValue(new ChatMessage(input.getText().toString(), mFirebaseAuth.getCurrentUser().getDisplayName()));

Would appreciate if anyone can come up with a nice and quick solution to this problem. Google Firebase team come to rescue!

EDIT

Upon @Frank's request, this is the java class of ChatMessage that I am using inside my setValue() :

package com.xxx.xxxxx;

import android.support.v7.app.AppCompatActivity;
import com.google.firebase.database.IgnoreExtraProperties;
import java.util.Date;


/**

@IgnoreExtraProperties
public class ChatMessage extends AppCompatActivity {

    public String messageText;
    public String messageUser;
    public long messageTime;

    public ChatMessage(){}

    public ChatMessage(String messageText, String messageUser) {
        this.messageText = messageText;
        this.messageUser = messageUser;

        // Initialize to current time
        messageTime = new Date().getTime();
    }

    public String getMessageText() { return messageText; }
    public String getMessageUser() { return messageUser; }
    public long getMessageTime() { return messageTime; }


}//close ChatMessage

Similar stacktrace as seen [here](http://stackoverflow.com/q/40703001/4625829). Have you checked it out yet? — AL., Dec 05 '16 at 08:33
I do agree it's the same problem yet the solution doesn't work for me. — Sahir, Dec 05 '16 at 08:42
Without seeing the code that triggers this error, all we can do is speculate. Please share an [MCVE](http://stackoverflow.com/help/mcve). — Frank van Puffelen, Dec 05 '16 at 09:10

I found the problem. I was foolish enough to remove the following import after making the java class (ChatMessage) independent of acting like a java activity. And now I can pass my objects to the setValue without any problem!

import android.support.v7.app.AppCompatActivity;

And yes also this must be removed:

extends AppCompatActivity
