1 Aims and Objectives
Ø To gain experience in mobile application UI and program design.
Ø To gain practical skill of Android application development.
Ø To understand the constraints and limitation of mobile application and the ways to
overcome them.
Ø To obtain knowledge on connecting the mobile device to the internet services and
building a multi-tier distributed system.
2 Introduction
In this assignment, you are required to develop an Android Application to play a "15,20" game by
selecting a player on a server. You can use the following website to get the detail of this game:
https://zh.wikipedia.org/wiki/%E6%95%B8%E5%AD%97%E6%8B%B3
https://www.youtube.com/watch?v=IrYzM-NCIEs
3 Functional Requirements
Listed below are the basic requirements of your application. You need to refer to the Local
Database section for the database schema.

Semester 3 (2024/2025)
a) A main activity which contains a main menu for players to
choose. The three main functions are: Play, Your Records and
Close.
b) Game Play
When a player touches the "Play" button on the main menu, they start
to play the game. The game will let player choose an opponent from a
ListView.
And then player should choose his/her left and right hand coming
screens. The last step is choosing your guess from a ListView.
Finally, the game will download the hands and guess of your opponent
from an api server in a json format:
{"left":0,"right":5,"guess":10}
Since this stage is your turn, you should ignore the guess number in
the above json.
If you win the game, the game will show the result. For the example
below, the game will show a "Continue" button to let player to go to
next round.
For next round (your opponent's round), you only select your left and right hand and then show
the result, at this round, you should download and use the guess in the json.

Semester 3 (2024/2025)
For the above example, since your opponent correctly guess the number, the game will show the
result and a "Finish!" button to end the game and then go back to Main menu.
To simplify your work, you are always the first one to start the guess.
Note:
1. The above UI design is only a reference for a game play, you should design your own UI,
otherwise, your marks on UI design will get ZERO!
2. You are encouraged to design and implement extra features. 15% of the total mark will be
allocated on such additional functions. Refer to section 7 Marking Guidelines for more
details.
4 Local Database
A database GamesLog which contains a table to store the game history
for yours which store the date and time, the name of your opponents, the
result of the game (Win or Lost) and the number of rounds to end game.
An activity for GamesLog properly show the data stored in the local
database. Your list should show the result of a game.
The database scheme described here is an extremely simple one. Many
fields are intended not to be included in order to reduce the complexity of
this assignment. You are free to add columns and tables to the database to
fit for your own needs.
GamesLog (gameDate, gameTime, opponentName, winOrLost, rounds)
5 Opponents JSON Server
You can find your opponent from the server by using following url:
https://assign-mobileasignment-ihudikcgpf.cn-hongkong.fcapp.run
and the data returned is in JSON format.
The sample JSON string returned is shown below:
{"left":5,"right":5,"guess":15}
6 Additional Constraints
Ø The UI of the mobile application must be produced with Android widgets such as
TextView, CheckBox, and Spinner etc. Web-based UI is NOT allowed.
7 Marking Guidelines
You project will be assessed according to the items below.
Ø Database initialisation
Ø Level of completion
