# Step 2: Install Android SDK Command-Line Tools
echo "Installing Android SDK Command-Line Tools..."

# Download the latest Android SDK command-line tools
SDK_TOOLS_URL="https://dl.google.com/android/repository/commandlinetools-linux-7583922_latest.zip"
wget $SDK_TOOLS_URL -O sdk-tools.zip

# Create the SDK directory
mkdir -p $HOME/Android/Sdk/cmdline-tools

# Extract SDK Command-Line Tools
unzip sdk-tools.zip -d $HOME/Android/Sdk/cmdline-tools

# Make the extracted directory structure compatible
mv $HOME/Android/Sdk/cmdline-tools/cmdline-tools $HOME/Android/Sdk/cmdline-tools/latest

# Accept the SDK licenses
$HOME/Android/Sdk/cmdline-tools/latest/bin/sdkmanager --licenses

# Step 3: Install NDK and other SDK components (platform-tools, build tools, etc.)
echo "Installing Android NDK and platform tools..."
$HOME/Android/Sdk/cmdline-tools/latest/bin/sdkmanager "ndk;21.4.7075529" "platform-tools" "build-tools;30.0.3"

# Step 4: Set up Android SDK environment variables
echo "Setting up Android SDK environment variables..."

# Define SDK path
ANDROID_SDK_PATH=$HOME/Android/Sdk

# Add environment variables for the SDK
echo "export ANDROID_HOME=$ANDROID_SDK_PATH" >> ~/.bashrc
echo "export PATH=\$PATH:\$ANDROID_HOME/tools:\$ANDROID_HOME/platform-tools:\$ANDROID_HOME/cmdline-tools/latest/bin" >> ~/.bashrc

# Reload bashrc to apply changes
source ~/.bashrc

# Step 5: Install Flutter via the webi.sh script
echo "Installing Flutter using the webi.sh script..."
curl -sS https://webi.sh/flutter | sh

# Add Flutter to the system PATH
echo "export PATH=\$PATH:\$HOME/.webi/flutter/bin" >> ~/.bashrc
source ~/.bashrc

# Step 6: Update Flutter configuration for Android SDK
flutter config --android-sdk $ANDROID_SDK_PATH

# Step 7: Run flutter doctor to check for issues
flutter doctor

echo "Android SDK, NDK, Flutter, cmake, and ninja setup completed."

Thank you for the script to install the Android toolchain without Android Studio.

I would like to note

Line 6: openjdk-11-jdk on current Debian (12.8) is no longer available via default package manager. openjdk-17 is the default for Debian 12.8.
Line 39: $ANDROID_HOME/tools does not exist. Do you mean $ANDROID_HOME/build-tools/35.0.0 ?
