Create A Data Entry Form, Database, And Test In Android

Create a data entry form, database, and test in an Android application

In the prior phase, you started work on some of the application’s graphical user interface (GUI). In this assignment, you will add a data entry form to the GUI and create a local database that will synchronize data to the isolated storage container of the mobile device. The following are the steps that you need to accomplish: Create a second page with a data entry form and the following fields: recipename, category, ingredients, and instructions. Make the Category field a dropdown box that contains the recipe categories listed in the Individual Project for Unit 2. Create Add and Delete buttons. Create the database necessary to store the information associated with the data entry form. Modify the application code to support addition and deletion of data in the database. Test the application in the Android Phone Emulator. Create screenshots of all of the relevant screens of your running application, and save them in a Word document named "yourname_ITSD427_IP3.docx." You should also use this document to describe the work you performed for this assignment, with specific details regarding the locations and changes of the code you created and modified. Save and close the project. Zip the entire project, including your screenshots and work description, to a file named "yourname_ITSD427_IP3.zip," and submit the zip file to the dropbox.

Paper For Above instruction

This assignment focuses on enhancing an existing Android application by integrating a data entry form, establishing a local database, and testing the application's functionalities comprehensively. Building upon the previous work on the application's GUI, the main objective is to create a seamless user interface that supports the input, storage, retrieval, and deletion of recipe-related data. This process involves several critical steps, including designing the user interface with precise specifications, developing the underlying database, and ensuring proper interaction between the GUI and the database.

The first step necessitates creating a second page within the application that hosts a data entry form. This form must include fields for recipe name, category, ingredients, and instructions. The category field's implementation as a dropdown box is particularly significant because it standardizes input and minimizes errors, facilitating easier data management. The dropdown list should contain predefined recipe categories previously listed in the Individual Project for Unit 2, ensuring consistency across the application's data sets.

Next, functional buttons—specifically Add and Delete—must be incorporated to enable users to manage their recipe data efficiently. The Add button should trigger the insertion of the data entered in the form into the local database, whereas the Delete button should facilitate the removal of specific entries, likely based on a selected or specified recipe. These buttons require appropriate event handlers, which must be coded carefully to perform the respective database operations without errors.

Developing the database component involves creating a structured, relational database that stores recipe data securely and efficiently on the device. This requires defining tables with columns corresponding to the form fields, along with establishing primary keys and potentially other constraints to ensure data integrity. Modifying the existing application code entails writing database helper classes or functions that manage database creation, upgrade, insertion, and deletion operations. These functions form the backbone of the application's data management capabilities, linking user interface actions to persistent storage.

Subsequently, testing becomes a crucial phase. The application must be tested thoroughly within the Android Phone Emulator to verify that data entry, addition, and deletion functionalities work as intended. Testing should include inputting sample data, adding entries to the database, deleting specific entries, and observing the changes in the UI and database state. Capturing screenshots of all relevant screens—including the data entry form, confirmation of data additions, and deletions—is essential for documentation and evaluation.

Documentation plays a vital role in this process. A Word document named "yourname_ITSD427_IP3.docx" should be compiled, containing detailed descriptions of all work performed. This includes specifying where in the code the new or modified segments are located, such as UI layout files, event handler code, and database helper classes. Clear explanations of how the application logic flows from user interaction through database operations are necessary to demonstrate understanding and proper implementation.

Finally, the project light must be preserved by saving and closing the Android project properly. The entire project directory, including the code, resources, screenshots, and work description, should be compressed into a ZIP file named "yourname_ITSD427_IP3.zip." This ZIP file, along with the screenshots and documentation, must be submitted via the designated dropbox. Proper organization and detailed documentation will ensure transparency, reproducibility, and a solid foundation for assessing the correctness and completeness of the assignment.
