Test project

You are expected to implement a small chat application.

1. Add dummy chat view

• It has a chat message list
• It has an edit text view
• It will append the new text to the list upon submit
• 

2. Integrate to Firebase

• Follow installation steps https://www.firebase.com/docs/android/quickstart.html
• Firebase reference is https://mysquar-test.firebaseio.com/chat
• Compile and run the project to make sure the integration is correct

3. Write to Firebase

• For each message submitted in step #1, it should also be saved to Firebase
• Save data to Firebase https://www.firebase.com/docs/web/guide/saving-data.html
• Use Getting the Unique ID Generated by push()
• Data structure should look like this:

{
  "chat": {
    $messageId1: "Message 1",
    $messageId2: "Message 2"
  }
}

4. Read from Firebase

• Read data from Firebase https://www.firebase.com/docs/android/guide/retrieving-data.html
• Should use Child Added event type, as the messages are saved in a list
• Compile and run the app on 2 devices to test the real-time chat

5. Add user name to chat

• Generate a unique user name, "USER_<UNIQUE_4_DIGITS_NUMBER>"
• Change data structure to support user name

{
  "chat": {
    $messageId1: {
      "username": "USER_1234",
      "message": "Message 1",
    },
    $messageId2: {
      "username": "USER_5678",
      "message": "Message 2",
    }
  }
}

• Change chat message item type to reflect sender and receiver
• 

6. Support offline mode

• Chat messages after being synced from Firebase should be cached locally with SQlite
• Should not use Firebase.getDefaultConfig().setPersistenceEnabled(true); as it is not stable
• Can use any kind of ORM in Android
