Building Your First Simple Mobile App – A Step-by-Step Guide

Creating a To-Do App: Let’s build a simple To-Do app, where users can add tasks and mark them as complete.

Key Features:

• UI Layouts: Use LinearLayout (Android) or StackView (iOS) to organize tasks vertically.
• Adding Tasks: Create an input field for users to type tasks and a button to add them to a list.
• Marking Tasks Complete: Add a checkbox or a button to allow users to mark tasks as complete.

Local Data Storage:

• Android: Use SharedPreferences to store small pieces of data like task completion.
• iOS: Use UserDefaults to store similar data.

Testing on Emulator: Both Android Studio and Xcode provide virtual devices to test the app. The emulator simulates real-device behavior, including touch events, camera input, and network connectivity.
