Architecture

• App UI layer (Activity/Fragment/Compose wrapper).
• Meeting orchestration layer (init/auth/join/start state machine).
• SDK facade layer (mobilertc.aar interfaces and controllers).
• Backend signing service (short-lived signature/JWT issuance).

Reference Flow

Why this split

• Keeps SDK secret server-side.
• Prevents UI from owning auth/security logic.
• Enables deterministic retry policy on join/start failures.
