Project 1 - Android - IF3111 Platform-based Application Development

13513021 - Erick Chandra

In IF3111 course, all students have to accomplish the app completion within certain deadline. The original specification is available here in Bahasa Indonesia.

This application mainly have the functionality of guessing the places in Bandung Institute of Technology. There are 10 places for guessing:

• GKU Barat
• GKU Timur
• Intel
• CC Barat
• CC Timur
• DPR
• Oktagon (changed; previously Sunken)
• Perpustakaan
• PAU
• Kubus

Inside the application, it must communicate with the server (provided by lab assistants) and have certain communication convention such as follows.

Location Request

These are the client and server communication via JSON string passed by socket connection.

First Client Request

{“com”:”req_loc”,”nim”:”13513021”}

First Server Request

{“status”:”ok”,”nim”:”13513021”,”longitude”:”6.234123132”,”latitude”:”0.1234123412”,”token”:”21nu2f2n3rh23diefef23hr23ew”}

Send Answer (Client to Server)

{“com”:”answer”,”nim”:”13513021”,”answer”:”labtek_v”, ”longitude”:”6.234123132”,”latitude”:”0.1234123412”,”token”:”21nu2f2n3rh23diefef23hr23ew”}

Server Response (if the answer is correct)

{“status”:”ok”,”nim”:”13513021”,”longitude”:”8.13215123214”,”latitude”:”9.1234123412”,”token”:”124fewfm32r32ifmwder42”}

Server Response (if the answer is incorrect)

{“status”:”wrong_answer”,”nim”:”13513021”,”token”:”124fewfm32r32ifmwder42”}

Server Response (if the client has reached the third correct answer therefore finish)

{“status”:”finish”,”nim”:”13513021”,”token”:”124fewfm32r32ifmwder42”,”check”:1}

Important: The given token must be used when making the next reply. Otherwise it will be an error.

Detailed Application Specification

• Application must be able to receive message from the server with JSON format, containing location (latitude and longitude) and token.
• Application must be able to calculate location point (latitude and longitude) and show the location indocator on the map view. The map will be implemented with Google Map API.
• There is a navigation arrow located on the map. The default direction is North. In order to implement this, sensors might be utilised.
• Application must be able to send camera intent.
• Photo could be taken but it is not compulsory to upload the photo to the server.
• Applicationmust be able to send message to the server with JSON format containing location information (latitude, longitude), Student ID, and token.
• Use of supporting SDK for this project.
• For some view, there are some differences when rotating the orientation (landscape vs portrait).
• Colours, fonts, and styling are not included in major marking. However, button position on the screen is important.
• Server replies must be shown with Toast or Alert Dialogue.
• Whenever the app uses the sensor, it must release all sensors by the time the user leaves the activity to reduce unnecessary battery consumption and to avoid some performance issues.
