#   - nvm at ~/.nvm
#   - Node LTS via nvm

#   - SDK licenses accepted non-interactively

TWA toolchain setup complete.

All tools are installed user-locally. Add the following to your shell rc
(~/.bashrc or ~/.zshrc) so they're available in new shells:

  # SDKMAN (Java)
  export SDKMAN_DIR="${SDKMAN_DIR}"
  [ -s "\$SDKMAN_DIR/bin/sdkman-init.sh" ] && . "\$SDKMAN_DIR/bin/sdkman-init.sh"

  # nvm (Node)
  export NVM_DIR="${NVM_DIR}"
  [ -s "\$NVM_DIR/nvm.sh" ] && . "\$NVM_DIR/nvm.sh"

  # Android SDK
  export ANDROID_HOME="${ANDROID_SDK_ROOT}"
  export ANDROID_SDK_ROOT="${ANDROID_SDK_ROOT}"
  export PATH="\$ANDROID_HOME/cmdline-tools/latest/bin:\$ANDROID_HOME/platform-tools:\$PATH"

  # @bubblewrap/cli (npm prefix)
  export PATH="${NPM_PREFIX}/bin:\$PATH"

After updating your rc, open a new shell and verify:
  javac -version
  node --version
  sdkmanager --version
  bubblewrap --version
