    To learn more about AVDs, check out Managing AVDs.

  16. In the Device Manager dialog, click the Run icon to the right of your desired AVD. The emulator starts up and displays the default canvas for your selected Android OS version and device.

Set up your target Android device

#

help Help

To configure your Flutter app to run on a physical Android device, you need an Android device running Android API level 21 or later.

  1. Enable Developer options and USB debugging on your device as described in the Android documentation.

  2. [Optional] To leverage wireless debugging, enable Wireless debugging on your device as described in the Android documentation.

  3. Plug your device into your windows computer. If your device prompts you, authorize your computer to access your device.

  4. Verify that Flutter recognizes your connected Android device.

    By default, Flutter uses the version of the Android SDK where your adb tool is based. To use a different Android SDK installation path with Flutter, set the ANDROID_SDK_ROOT environment variable to that installation directory.

Agree to Android licenses

#

help Help

Before you can use Flutter and after you install all prerequisites, agree to the licenses of the Android SDK platform.

  1. Open an elevated console window.

  2. Run the following command to enable signing licenses.

    flutter doctor --android-licenses

    If you accepted the Android Studio licenses at another time, this command returns:

    [========================================] 100% Computing updates...
All SDK package licenses accepted.

    You can skip the next step.

  3. Before agreeing to the terms of each license, read each with care.

How to fix the error of finding Java install

You might have an issue with the Android SDK locating the Java SDK.

flutter doctor --android-licenses

ERROR: JAVA_HOME is set to an invalid directory: /Applications/Android\ Studio.app/Contents/jre/Contents/Home

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

Android sdkmanager tool was found, but failed to run
(/Users/atsansone/Library/Android/sdk/cmdline-tools/latest/bin/sdkmanager): "exited code 1".
Try re-installing or updating your Android SDK,
visit https://flutter.dev/to/macos-android-setup for detailed instructions.

The flutter doctor command returns this error because of how the JAVA_HOME variable was set. When you add the path to JAVA_HOME, you can add a backslash to the space between Android and Studio or enclose the entire path in matching quotes. You cannot do both.

Look for your JAVA_HOME path in your appropriate shell resource file.

Change it from:

bash
export JAVA_HOME="/Applications/Android\ Studio.app/Contents/jre/Contents/Home"

to:

bash
export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/Contents/Home"

Do not include the backslash between Android and Studio.

To load this updated environment variable, reload your shell. This example uses the zsh resource file.

source ~/.zshrc

Run Flutter doctor

#

The flutter doctor command validates that all components of a complete Flutter development environment for Windows.

  1. Open PowerShell.

  2. To verify your installation of all the components, run the following command.

    PS C:> flutter doctor

As you chose to develop for Android, you do not need all components. If you followed this guide, the result of your command should resemble:

Running flutter doctor...

Troubleshoot Flutter doctor issues

#

When the flutter doctor command returns an error, it could be for Flutter, VS Code, Android Studio, the connected device, or network resources.

If the flutter doctor command returns an error for any of these components, run it again with the verbose flag.

PS C:> flutter doctor -v

Check the output for other software you might need to install or further tasks to perform.

If you change the configuration of your Flutter SDK or its related components, run flutter doctor again to verify the installation.
