DroidLink 2.0

DroidLink 2.0

DroidLink 2.0 combines the responsive 1.0.5 streaming experience with a polished, game-focused interface.

What's new:

• Clean fullscreen gameplay experience
• Compact 48 dp in-game menu control
• New lightweight session overlay
• Instant Resume action
• Easy access to Diagnostics, Game Audio, and Settings
• Reliable Disconnect action using the existing session cleanup flow
• Predictable Android Back-button behavior during gameplay
• More polished Host and Join main-menu actions
• Improved navigation and consistent compact button styling
• Updated DroidLink 2.0 branding and application metadata

Preserved systems:

• Gaming Low-Latency Playout Mode
• H.264 hardware codec preference
• Firebase signaling
• Direct P2P and TURN fallback
• Controller transport and DroidLink Player 2
• Game audio
• Automatic reconnection and session cleanup

Validation:

• testDebugUnitTest passed
• assembleDebug passed
• APK metadata verified as version 2.0

This is the current primary DroidLink build. Physical-device testing is still recommended across different Android devices and display orientations.

DroidLink 2.0 V2

DroidLink 2.0 V2

Security and stability hardening:

• Validates room codes, SDP, ICE candidates, and controller payload sizes
• Limits stale, duplicate, oversized, and excessive signaling data
• Uses secure room-code generation and tighter TURN response parsing
• Disables cleartext Android traffic and app-data backup
• Restricts screen-capture service broadcasts to DroidLink
• Improves broad Android controller mapping and Controller Test behavior
• Preserves the working WebRTC video, game-audio, signaling, and low-latency controller architecture

Important scope:

• Players 3 and 4 are not enabled in this build. Safe multi-peer video requires a tested multi-PeerConnection host architecture.
• Microphone voice chat is not enabled. It requires safe mixing/isolation from the existing game-audio capture pipeline.
• Firebase server-side authorization still requires deployed Firebase Authentication/security rules; APK-side validation alone is not a complete access-control boundary.

Build verification:

• :app:testDebugUnitTest passed
• :app:assembleDebug passed

Physical-device security, streaming, and controller verification is still required.

DroidLink 1.0.5 Gaming Playout

DroidLink 1.0.5

What's new:

• Added Gaming Low-Latency Playout Mode
• Reduced configured receive-side video playout maximum from 80 ms to 60 ms
• Separated game audio and video synchronization groups to prevent audio buffering from delaying video
• Improved remote game-audio routing with explicit game/media output attributes
• Added audio jitter-buffer, concealment, output-state, and A/V sync diagnostics
• Added requested capture FPS and adaptation-level diagnostics
• Preserved Firebase signaling, ICE/TURN, H.264, controller transport, Player 2, and reconnect systems

Beta status:

• This is a beta/debug build intended for physical-device testing
• Actual receive latency reduction and two-way game audio require verification on real devices
• Keep DroidLink 1.0.4 available as the rollback build

DroidLink 1.0.4 Receive Latency

DroidLink 1.0.4 Receive Latency

Focused receive-side latency update built on the protected DroidLink 1.0.3 baseline.

• Added bounded WebRTC low-latency video playout with normal jitter buffering preserved
• Set a best-effort 0–80 ms receive playout range
• Added low-latency decode pacing and a one-frame decode-queue threshold
• Corrected jitter-buffer interval, target, minimum, range, and trend diagnostics
• Corrected inbound/outbound bitrate direction and candidate-pair reporting
• Added separate receive and decode FPS diagnostics
• Replaced misleading unavailable FPS, codec, and queue values with accurate Unavailable labels
• Relabeled frame age as an estimated pipeline delay rather than synchronized motion-to-photon latency
• Preserved SurfaceViewRenderer, H.264, MediaCodec, game audio, Firebase, TURN, ICE, PeerConnection, controller transport, Player 2, Winlator, reconnect, cleanup, and UI systems

Validation:

• 16 unit tests passed

DroidLink 1.0.3 Low Latency

DroidLink 1.0.3 Low Latency

Final low-latency optimization built on the protected DroidLink 1.0.2 baseline.

• Removed the extra diagnostic VideoSink from the remote decoder path
