Issue Description
When a participant experiences a sudden network disconnection and the application container is forcefully closed during an active video session, the remote receiving participants encounter a persistent rendering freeze. Upon rejoining the channel with the camera explicitly deactivated, the remote screens continue to display the final video frame captured prior to the disconnection, failing to update the interface to indicate the stream is offline.
Platform and SDK Context
Deployment Environment: Android Client Implementation
Framework Infrastructure: Application Platform as a Service Architecture
Tracking Identifier: Core Optimization Update APAAS 14935
Error Characterization
The runtime environment generates no explicit user interface error codes or fatal exceptions. The synchronization failure manifests as a static media frame retention on remote peer terminals post client reconnection.
Root Cause Analysis
The persistent rendering freeze originates from a session state tracking mismatch within the signaling gateway layer during uncoordinated channel departures.
When the client application terminates abruptly without executing a standard room exit protocol, the backend routing registry retains the historical user presence token as active. Upon re-entering the channel, the infrastructure fails to clear the legacy stream mappings and omits syncing the updated inactive media state with the active session matrix. Consequently, the remote subscription pipeline continues to parse the obsolete stream validation records, preventing the canvas from triggering the camera off interface update.
Solution and Resolution Steps
Implement Mandatory Client Request Update
Update the Android application implementation to integrate the modified room entry signaling routine. The updated logic enforces the dispatch of a new validation HTTP POST request during the initialization pipeline when entering a room.
Enforce Prior Session Teardown
Configure the connection manager to evaluate the user online status tokens upon room entry. If the infrastructure identifies the re-entering entity as still online due to a legacy crash, the gateway must forcefully log out the old session, tear down the residual Real Time Messaging link, and re-establish a clean signaling handshake before finalizing the new room login.
Migrate to the Patched Framework Release
Upgrade the project build to the latest available software development kit version incorporating the APAAS 14935 patch. The updated framework automatically coordinates the structural API flow to refresh user media properties and broadcast the correct camera status to remote peers post reconnection.
