- Add GeminiCloudModel: proxies inference to Gemini 2.0 Flash via HTTPS
using HttpURLConnection (no new deps). Supports both blocking and SSE
streaming. Works from any context — background, emulator, CI.
- Fix background inference: OnDeviceModel.create() now accepts an apiKey;
when set, GeminiCloudModel is selected immediately, bypassing Gemini
Nano's foreground-only restriction. ApiServerService reads the key from
SharedPreferences at startup.
- Add API key UI: password field in MainActivity saved to SharedPreferences
before the service starts; disabled while server is running.
- Add GitHub Actions CI (.github/workflows/ci.yml): build job produces a
debug APK artifact; test job spins up a KVM-accelerated Android 31
emulator, installs the APK, writes the GEMINI_API_KEY secret into
SharedPreferences via adb run-as, starts the service, and runs curl
assertions against /health, /v1/models, /v1/chat/completions, and the
SSE streaming endpoint.
- Add release workflow (.github/workflows/release.yml): triggered on v*
tags, builds the APK and creates a GitHub Release with it attached.

- Bump Kotlin from 2.0.21 to 2.1.20 for ML Kit genai metadata 2.2.0 compat
- Fix GeminiNanoModel imports: DownloadStatus/FeatureStatus moved to genai.common,
TextPart/generateContentRequest moved out of .type subpackage
- Fix MediaPipeModel: replace removed setTopK/setTemperature/setRandomSeed
with setMaxTopK (MediaPipe 0.10.24 API)
- Fix gradlew: remove broken lines that passed GradleWrapperMain as task arg

- GeminiNanoModel: Rewrite to use actual ML Kit Prompt API
(Generation.getClient(), checkStatus(), download(), warmup())
- MediaPipeModel: Fix streaming to use sync fallback since
MediaPipe requires result listener set at build time
- ApiModels: Add @SerializedName("object") for OpenAI compat,
add "created" timestamp to ChatResponse/StreamChunk
- settings.gradle.kts: Fix dependencyResolutionManagement typo
- MainActivity: Use GradientDrawable.setColor() to preserve
oval shape on status dot
- Add Gradle wrapper scripts (gradlew, gradlew.bat, jar)

Android app that turns a Pixel 10 into a free AI API server by leveraging
the Tensor G5's on-device AI capabilities through an embedded HTTP server.
Key components:
- Dual AI backend: Gemini Nano (ML Kit Prompt API) + MediaPipe LLM fallback
- OpenAI-compatible REST API (chat/completions, completions, models, health)
- NanoHTTPD embedded server with CORS support and SSE streaming
- Foreground service with wake lock for persistent background operation
- Material Design 3 dashboard with live request logging
All inference runs entirely on-device — zero cloud costs, full offline capability.
