Android Studio, SDK, Emulator, and Flutter Configuration

Setting up Android Studio, the Android SDK, an Android Emulator, and the Flutter SDK correctly is an important step before developing Flutter applications for Android. A complete configuration allows you to create Flutter projects, write Dart code, run applications, debug applications, use hot reload, and test applications on virtual or physical Android devices.

Flutter's current Android setup requires the Flutter SDK in addition to Android Studio. Installing the Flutter plugin alone does not install the Flutter SDK. The Flutter SDK's bin directory must also be available so that the flutter command can be used from a terminal. :contentReference[oaicite:0]{index=0}

flutter doctor --android-licenses

Review the license prompts and accept the necessary licenses. Flutter's documentation recommends this command as part of Android setup. :contentReference[oaicite:12]{index=12}

After completing the process, run:

flutter doctor

20. What is an Android Emulator?

The Android Emulator is a software-based Android device that runs on your computer. It allows developers to test applications without requiring a physical Android phone.

Android Emulator is included with Android Studio and can simulate different Android device configurations and API levels. :contentReference[oaicite:13]{index=13}

Advantages of an Emulator

• No physical Android phone is required.
• Different device profiles can be tested.
• Different Android versions can be tested.
• Screen sizes and resolutions can be tested.
• Debugging can be performed directly from the development computer.

21. What is an AVD?

AVD stands for Android Virtual Device.

An AVD is a configuration that defines characteristics such as device type, Android system image, screen configuration, and other virtual hardware settings.

Android Developers describe an AVD as a configuration that defines the characteristics of an Android device that you want to simulate in the Android Emulator. :contentReference[oaicite:14]{index=14}

22. Create an Android Virtual Device

Step 1: Open Device Manager

If a project is open:

More Actions
  ↓
Virtual Device Manager

Step 2: Create Virtual Device

1. Open Device Manager.
2. Click the Create Virtual Device button.
3. Select Phone or Tablet.
4. Select a device definition.
5. Click Next.

These are the current Device Manager steps documented by Flutter and Android Developers. :contentReference[oaicite:15]{index=15}

23. Select an Android System Image

After selecting a hardware profile, choose an Android system image.

1. Review the available system images.
2. Select a suitable Android version.
3. Download the image if it is not installed.
4. Wait for the download to finish.
5. Click Next.

Choose an image compatible with your development computer's CPU architecture. Flutter's current documentation notes selecting x86 images or ARM images according to whether the development computer is x64 or Arm64. :contentReference[oaicite:16]{index=16}

24. Configure Emulator Graphics

Hardware graphics acceleration can improve emulator rendering performance.

1. Open the virtual device configuration.
2. Open the additional settings.
3. Find the graphics or emulated performance settings.
4. Select an option that uses hardware acceleration where appropriate.
5. Save the configuration.

Flutter's current Android setup instructions recommend a graphics option that mentions hardware acceleration for the emulator. :contentReference[oaicite:17]{index=17}

25. Start the Emulator

After creating the AVD:

1. Open Device Manager.
2. Find the created virtual device.
3. Click the Run/Play button.
4. Wait for Android to boot.
5. Unlock the virtual device if necessary.

Once the emulator is running, Flutter can detect it as an available Android target.

26. Check Available Flutter Devices

Open the terminal and run:

flutter devices

Flutter should display available targets, including the running Android emulator if it has been configured correctly.

Another useful command is:

flutter emulators

Flutter's Android setup documentation recommends using both flutter emulators and flutter devices to verify emulator and device configuration. :contentReference[oaicite:18]{index=18}

27. Configure a Physical Android Device

Instead of using an emulator, Flutter applications can also be run on a real Android phone.

Basic Steps

1. Open the phone's Settings.
2. Enable Developer Options.
3. Enable USB Debugging.
4. Connect the phone to the computer.
5. Accept the USB debugging authorization prompt if displayed.
6. Install any required device-specific USB driver on Windows.
7. Run flutter devices.

Android Developers document USB debugging as part of preparing a physical Android device for development and debugging. :contentReference[oaicite:19]{index=19}

28. USB Debugging

USB debugging allows development tools on your computer to communicate with an Android device through Android Debug Bridge (ADB).

Basic Workflow

Android Phone
      |
      | USB Cable
      v
Computer
      |
      v
ADB
      |
      v
Flutter / Android Tools

Once the device is authorized and recognized, Flutter can use it as a deployment target.

29. Wireless Debugging

Modern Android devices can also support wireless debugging. This can allow development tools to communicate with the Android device over Wi-Fi instead of a USB cable, when supported and configured.

Flutter's current Android setup documentation includes wireless debugging as an option for physical Android devices. :contentReference[oaicite:20]{index=20}

30. Configure Flutter SDK Path in Android Studio

When creating a Flutter project in Android Studio, Android Studio asks for the location of the Flutter SDK.

Example

C:\src\flutter

Make sure the selected directory is the Flutter SDK root, not the bin directory itself.

Correct

C:\src\flutter

Do Not Select

C:\src\flutter\bin

The SDK path should point to the Flutter SDK directory. The Flutter CLI executable is located inside its bin directory.

31. Create a Flutter Project in Android Studio

1. Launch Android Studio.
2. Open the Welcome screen.
3. Click New Flutter Project.
4. If a project is already open, select File > New > New Flutter Project.
5. Select Flutter.
6. Verify the Flutter SDK path.
7. Click Next.

10. Configure additional project information.
11. Click Finish.

Flutter's current documentation describes this workflow for creating a new Flutter project in Android Studio. :contentReference[oaicite:21]{index=21}

32. Example Project Name

Use a simple Flutter project name such as:

my_flutter_app

Other examples:

student_app
shopping_app
todo_app
weather_app
flutter_demo

For Dart and Flutter projects, lowercase names with underscores are commonly used.

33. Run Your First Flutter Application

After creating the project, start the Android emulator or connect a physical Android device.

Then run:

flutter devices

After confirming the device, run:

flutter run

You can also run the application directly using Android Studio's Run button.

34. Select the Flutter Target Device

Android Studio provides a device selector in the IDE toolbar.

Typical targets can include:

• Android Emulator
• Physical Android phone
• Chrome
• Windows
• Other configured Flutter targets

Select the desired Android target and click the Run button.

├── windows/
├── macos/
├── linux/
├── pubspec.yaml
├── pubspec.lock
└── README.md

36. Basic Flutter Application

Use the following application to test whether your Android Studio, Flutter SDK, Android SDK, and emulator configuration is working correctly.

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Flutter Setup Test',
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Flutter Setup'),
        ),
        body: const Center(
          child: Text(
            'Flutter is configured successfully!',
            style: TextStyle(
              fontSize: 24,
              fontWeight: FontWeight.bold,
            ),
            textAlign: TextAlign.center,
          ),
        ),
      ),
    );
  }
}

Expected Result

When the application runs successfully, the emulator or physical Android device should display an AppBar with the title Flutter Setup and a message in the center of the screen.

37. Test Hot Reload

Flutter's hot reload allows developers to quickly apply many code changes during development without performing a complete application restart.

Change:

Flutter is configured successfully!

to:

Welcome to Flutter Development!

Save the file and trigger hot reload from Android Studio.

The updated text should appear in the running application while the application state is generally preserved.

38. Hot Reload vs Hot Restart

39. Configure Android Studio for Flutter Debugging

Android Studio can run Flutter applications in either run or debug mode.

Run Mode

Run mode launches the application without requiring debugger breakpoints.

Debug Mode

Debug mode allows you to use debugging tools such as breakpoints, variables, stack frames, and console output.

Flutter's Android Studio documentation describes using the Run and Debug actions from the IDE toolbar. :contentReference[oaicite:22]{index=22}

40. Flutter Inspector

Flutter Inspector is useful for examining the widget tree and investigating layout issues.

It Can Help You Understand:

• Widget hierarchy.
