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. The deliverable is 1 screenshot. For the second part, 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 app showing total bill, tip percentage, tip amount, and total amount with tip, and insert it into the Word document. The tip calculator should work correctly for at least two different bill amounts. Deliverable is 2 screenshots. Include your name at the top of the Word document and upload it to the portal under “Unit 1 IP”. Use any resources as needed.
Paper For Above instruction
Introduction
The rapid evolution of mobile technology has transformed the way individuals and businesses communicate, operate, and engage with services worldwide. Developing proficiency in creating functional and user-friendly mobile applications is essential for aspiring developers. This paper discusses initial Android Studio app development exercises aimed at establishing fundamental skills, including creating a simple "Hello World" app, a tip calculation app, and other essential components for mobile app development.
Part 1: Basic "Hello World" App Development
The first step in mobile development involves understanding the basic architecture of an Android application. Creating a "Hello World" app serves as an introductory exercise to familiarize students with Android Studio, layout design, and resource management. The app displays a welcome message, "Welcome to CS310," along with an appropriate image. This task develops foundational skills such as setting up Android Studio projects, designing XML-based user interfaces, and deploying apps on an emulator.
To achieve this, students select an appropriate image, configure a TextView to display the welcome message, and insert an ImageView for the selected image. Building and launching in the Android emulator provides practical experience with app deployment. Taking a screenshot of the running app helps document the progress and understanding of UI design principles.
Part 2: Tip Calculator App
The second assignment enhances functional development skills by creating an app that calculates tip amounts based on user input. The app requires input fields for total bill amount and tip percentage, and displays calculated tip and total payable amount upon computation. This builds a deeper understanding of user input handling, arithmetic operations, and display updates within Android applications.
Students must test and demonstrate the app with at least two different bill amounts to ensure accuracy. The screenshot must show user inputs and the corresponding calculations. This exercise underscores the importance of validating user data, performing real-time calculations, and dynamically updating the UI to enhance user experience.
Assessment and Submission
Students are instructed to compile the screenshots into a Word document, clearly labeled, and include their name at the top. Proper app functioning, UI clarity, and correct calculations are key evaluation criteria. Resources such as textbooks and internet references can be used to aid development, emphasizing the importance of resourcefulness and problem-solving skills.
Conclusion
These initial exercises in Android Studio lay the groundwork for more advanced app development projects. By creating simple, functional apps, students gain confidence in their ability to design, develop, and deploy mobile applications. These foundational skills are essential stepping stones toward more complex projects like drawing apps, games, and data-driven applications that integrate external data sources and sophisticated user interactions.
