FAQs

Choosing BT vs Direct

Control bursts and terse strings → BT suffices. Imagery/APKs/large assets → prioritize P2P.

Origin of mocked assets on disk

Activities copy seeded files from assets/ into cache before transmitting.

Caveats

• APK transfer refuses to proceed until P2P is hot.
• Sample clientId is GlassSample — hoist to config for production bundles.
