Android setup
Install Android Studio
1. Install Android Studio on your computer.
2. Launch Android Studio and follow the 'Android Studio Setup Wizard' instructions. The latest Android SDK, Android SDK Command-line Tools, and Android SDK Build-Tools are installed, which are required by Flutter when working for Android.
3. Run flutter doctor to see if Flutter has found your Android Studio installation. If Flutter can't find it, use flutter config —android-studio-dir<directory> to change the Android Studio installation directory.
Set up your Android device
You'll need an Android smartphone running Android 4.1 (API level 16) or higher to run and test your Flutter app on an Android device.
1. On your device, enable Developer settings and USB debugging. The Android documentation contains detailed instructions. To enable developer options in your mobile phone, check as per need as it is different for each device.
2. Install the Google USB Driver if you're using Windows.
3. Connect your phone to your computer with a USB cable. Allow your computer to access your device if prompted by your device.
4. Run the flutter devices command in the terminal to see if Flutter recognizes your connected Android device. Flutter uses the version of the Android SDK that your adb tool is built on by default. You must set the ANDROID SDK ROOT environment variable to the location where the Android SDK is installed if you want Flutter to use it.
Agree to Android Licenses
Before you may utilize Flutter, you must agree to the Android SDK platform's licensing. After you've installed the tools described above, proceed to the next step.
1. Make sure you have Java 8 installed and that your JAVA HOME environment variable points to the JDK subdirectory. This should already be done if you're using Android Studio 2.2 or higher, as it comes with a JDK.
2. To begin signing licenses, open an elevated terminal window and type the following command.
flutter doctor --android-licenses
3. Before consenting to the conditions of each license, read them thoroughly.
4. After you've agreed to the licensing, run flutter doctor once more to make sure you're ready to utilize Flutter.
