Welcome to this comprehensive tutorial on how to create an Android app in Android Studio using Java that can detect incoming calls and display the phone number upon button click. In this video, we will guide you through the entire process, from setting up the necessary permissions to implementing the call detection functionality and retrieving the phone number.

**Step 1: Project Setup and Permissions**
To get started, we'll show you how to set up a new Android Studio project and configure the necessary permissions to access call-related information. You'll learn how to request the necessary permissions in the AndroidManifest.xml file and handle runtime permission requests for devices running Android 6.0 (Marshmallow) and above.

**Step 2: Implementing Call Detection Functionality**
In this step, we'll guide you through the process of implementing the call detection functionality in your Android app. You'll discover how to create a BroadcastReceiver to listen for incoming call events and handle call states such as ringing, off-hook, and idle. We'll also cover how to extract the incoming phone number from the call event.

**Step 3: Displaying Phone Number on Button Click**
Next, we'll explore how to display the incoming phone number upon button click. You'll learn how to set up a user interface with a button and use the call detection logic to retrieve the phone number when the button is clicked. We'll also cover how to show the phone number using a TextView or a custom dialog.

**Step 4: Enhancing the User Experience**
In this step, we'll focus on enhancing the user experience of your call detection app. We'll explore techniques such as displaying call information in a visually appealing way, handling edge cases such as missed calls or unknown phone numbers, and providing smooth transitions between different app states.

**Step 5: Testing and Refining the App**
Once the call detection functionality is implemented, we'll help you test your app on an emulator or a physical Android device. We'll guide you through refining the user interface, optimizing call detection performance, and addressing any potential bugs or issues.

**Conclusion:**
Congratulations on successfully creating an Android app that can detect incoming calls and display the phone number using Android Studio and Java! Through this tutorial, you've learned how to set up permissions, implement call detection functionality, and retrieve the phone number upon button click. You now have the skills to create your own call detection app and handle incoming call events with ease.
