Introduction To Mobile Solutions

Part I.

Unit:  Introduction to Mobile Solutions

Due Date:  Wed, 5/22/18

This is a 2-part IP designed to help you get started in Android Studio. Throughout the course, you will create mobile apps (using Java) that have common features, which will give you the building blocks necessary to build your own app, which you will turn in during Unit 5.

For this IP, you will create a basic “Hello World” app. Specifically, create an app using Android Studio that displays the following text on the GUI: “Welcome to CS310,” and includes an image. You may use any image appropriate to the welcome message. Build and launch the app in the Android emulator, take a screenshot of the running app, cut and paste the screenshot into a Word document.

  • Deliverable is 1 screen shot.

For the second part of this IP, you will create an app using Android Studio that calculates a tip amount based on a total bill amount and percentage input by the user. Build and launch the app in the Android emulator, take a screenshot of the running app (which should show the total bill amount, the tip percentage, the tip amount, and the total amount of the bill with the tip), cut and paste the screenshot into the same Word document you created for the first part of this IP.

  • Type your name at the top of the Word document and upload it to the portal under “Unit 1 IP.”
  • The tip calculator app needs to show that the app works and that the math is correct for at least two different bill amounts.
  • Deliverable for the tip calculator app is 2 screenshots.
  • You may use your textbook and Internet resources as a reference in fulfilling this assignment.

Part II

Deliverable Length:  Minimum 2 screenshots. See assignment for details.

For this IP, you will create a very simple drawing app using Android Studio. The purpose of this assignment is to give you more building blocks to use when programming apps. For full credit for this assignment, you should complete the following:

  1. Create a menu and display menu items on the app bar
  2. Detect when the user touches the screen and moves a finger
  3. Be able to change the color and width of a line
  4. Be able to save an image

To turn in this assignment, upload screenshots of the working app (from the emulator) as a Word document.

The screenshots need to show that the app works and that all of the parts listed work. At a minimum, students should upload 2 screenshots showing:

  • A drawing
  • Menu showing the different color choices and line widths

Part III

For this IP, you will create a game app. Choose 1 of the following games to create, using your textbook and Internet resources to help you:

  1. This is a quiz game app that will be text-based with images. The app should show the user a flag image, and the user must then choose the correct country that corresponds to the flag. The quiz should have 10 questions before showing the user the number he or she answered correctly and giving the option to play again. There should be a menu choice allowing the user to determine whether he or she wants 3, 6, or 9 tries to answer each quiz question.
  2. This is a graphic game. The user will have control of a cannon that shoots a ball at targets. The app should incorporate simple collision detection as well as sound. There should be a countdown clock on the screen to end the game. When the ball hits a target, the user should be given more time to play. When the time is up (the countdown clock reaches zero), the score should be displayed on a screen, along with an option to play the game again.

For this IP, upload a Word document containing screenshots that show the game app working in the emulator. The screenshots need to show that the app and all component parts work. As a minimum, upload the following for your chosen game app:

Quiz App

  1. Screenshot showing a flag image on the screen
  2. List of 3 choices
  3. List of 6 choices
  4. List of 9 choices
  5. Menu of choice of 3, 6, or 9
  6. Final screen showing correct/incorrect answer and giving option for playing again

OR

Cannon Ball App

  1. Start screen showing the game, cannon, ball, and timer
  2. A screenshot showing what happens when the user hits a target
  3. A screenshot showing what happens when the user misses a target
  4. A screenshot showing the countdown clock at zero, the final score, and the user having an option to play again (this could be on a fifth screen if you want)

Part VI

Students will create a weather app that processes JSON requests. This app will need to pull weather data from Web sources. Students will upload screenshots of the working app (from the emulator) in a Word Document.

For this IP, you will create a weather app that processes JSON requests. The app will need to adhere to the following:

  1. Allow the user to input a major city in the U.S.
  2. Connect to the free Web site: OpenWeatherMap.org to retrieve weather data.
  3. Create a ListView that displays 10 days of weather data for that city.

For this IP, upload a Word document containing screenshots that show the weather app working in the emulator. The screenshots need to show that the app and all component parts work. As a minimum, upload the following for your weather app:

  • Two different screenshots, each showing the results of a different city entered by the user.

Part V

  1. Identify the problem your app is designed to solve and explain how your app solves it (bullet points are fine).
  2. Describe any comparable apps currently on the market and explain how your app will be different or better.
  3. List your revised requirements (at least 10) and corresponding test case scenarios.
  4. Include your Pseudocode.
  5. Include screenshots of your working app (one slide for every app screen).
  6. Include a description of how you could incorporate either an ads bar or an in-app purchase into your app.
