Follow-up to #499, addressing review comments.

  • Drop runtime.GOOS == "android": CI builds with GOOS=linux, so it never fires. Termux is detected via TERMUX_VERSION (isTermux()).
  • On Termux, login prints a one-line stderr notice when the token is stored in the plaintext credentials file. Skipped when --insecure-storage is passed explicitly.

Test plan

  • go build ./..., go test ./cli/ credentials tests pass
  • mobilecli auth login on Termux prints the notice
  • mobilecli auth login --insecure-storage on Termux prints no notice

Summary by CodeRabbit

  • Bug Fixes
    • Android now uses its default credential storage unless insecure file storage is explicitly requested or the app is running in Termux. Termux users are notified when credentials are stored in plain text.

…storage

Follow-up to #499. runtime.GOOS is never "android" since CI builds with
GOOS=linux, so drop that check. On Termux, login now prints a notice to
stderr when the token falls back to the plaintext credentials file without
--insecure-storage.

📝 Walkthrough

Walkthrough

File storage is now selected when --insecure-storage is set or TERMUX_VERSION is non-empty. When Termux uses file storage without the flag, the CLI prints a plaintext-storage notice before saving the token.

Android hosts without the required Secret Service cannot persist login tokens through the declared Android package. Provide a supported storage backend or narrow the Android target declaration before merging.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Use a storage backend available on all declared Android targets.

When the Android npm entrypoint runs without TERMUX_VERSION, useFileStorage() returns false. storeToken then calls the Linux go-keyring backend. That backend requires a session D-Bus Secret Service and returns an error when the service is unavailable. auth login consequently fails to store the token on supported non-Termux Android hosts without that service.

Select a storage backend that supports the declared Android target, or limit the package metadata to hosts where the Secret Service backend is available.
