- To create a basic user interface - To create event listeners and handlers for UI components - To create a basic test plan - To work with fragments - To handle orientation changes Instructions You are charged with creating a simple calculator. You must satisfy the following requiren Functional and interface requirements: - Positive and negative numbers - Real numbers - $$+,?,?,l$$, and $$\%$$ (modulus -not percentages like a regular calculator) - Square root - Clear options C clears the entire display screen and the current calculation. - CE clears the most recent entry (e.g., the last digit you just entered) - The user must interact with the buttons, not the software keyboard - The app must handle rotations and still be beautiful and usable You can closely match an actual simple (basic) calculator, such as the following: - You must use: buttons, text views to complete the assignment - You must provide a test plan with at least three days on separate worksheet tabs indicating the tests that were performed - You must use fragments (one for top display, and one for bottom with buttons) If you do not use fragments, you will lose a significant number of points
