What it does
Health Connect is an agent skill from androidx/androidx. Comprehensive guide for Health Connect Jetpack SDK development. Includes AOSP workflow, feature implementation, naming standards, testing, and release phase requirements (Alpha/Beta/Experimental). Use when adding or modifying any Health Connect APIs in AndroidX.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile. It works with Android. The repository describes itself as: Development environment for Android Jetpack extension libraries under the androidx namespace. Synchronized with Android Jetpack's primary development branch on AOSP. The licence is Apache-2.0.
When your agent uses it
- Modifying any Health Connect APIs in AndroidX
Example prompts
- “/health-connect”
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 6c35dc9. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Health Connect loads about 1k tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 393 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Health Connect Jetpack SDK Development
Overview
This skill defines the end-to-end workflow for developing Health Connect features in the AndroidX repository (frameworks/support/health/connect/).
1. Development Environment & Workflow
- Root Directory: Always work from
frameworks/support/. - Git Strategy:
- Start a new branch:
repo start <branch_name> . - First commit:
git commit - Subsequent changes:
git commit --amend - Upload for review:
repo upload --cbr .
- Start a new branch:
- Sync to google3: Submission in AOSP triggers a "Safe Review" CL in Piper via Copybara. Approval in Piper triggers auto-submit and TAP.
2. Feature Implementation Workflow
Step 1: Platform API Availability
- Ensure backing platform APIs are available. If not, perform a self-service prebuilt drop (
go/androidx/playbook/update_sdk). - Map the version in
HealthConnectFeatures.kt(e.g., Baklava/Android 37 or specific U/V extensions).
Step 2: Define Feature & Versioning
- Add
FEATURE_*constant toHealthConnectFeatures.kt. - Update
FEATURE_TO_VERSION_INFO_MAP. - Access Control: Annotate every new public symbol with
@RestrictTo(RestrictTo.Scope.LIBRARY)during development to prevent unintentional release.
Step 3: Implement Models & Client
- Model Packaging: Create required Request/Response classes in a feature-specific package (e.g.,
androidx.health.connect.client.<feature_name>). This is the preferred approach for modularity and clarity. - Add methods to
HealthConnectClient.kt. - Intent Constants: Descriptive internal constants (e.g.,
ACTION_HEALTH_CONNECT_MATCHMAKING) should be used for platform delegation.
Step 4: Logic & Delegation
- Platform-Only Implementation: New features are developed for the platform (Android U+ / API 34+) using the system service. Do not add new feature logic to the legacy APK-based path (
HealthConnectClientImpl.kt). - Implement logic in
HealthConnectClientUpsideDownImpl.kt. - Check platform API availability before calling platform methods; throw
UnsupportedOperationExceptionif unavailable. - Note: This architectural shift ensures features leverage the system service and modern OS extensions.

3. Release Phases (Alpha vs. Beta)
Alpha Release
- Remove
@RestrictTo(RestrictTo.Scope.LIBRARY). - If the API is still evolving or not ready for final stable release, mark with an experimental annotation (e.g.,
@ExperimentalMatchmakingApi). - Submit for API review (
go/hc-jetpack-sdk-review-process).
Beta/RC/Stable Release
- Experimental Annotation: If the SDK version is Beta, RC, or Stable, new APIs must be marked with an experimental annotation unless they are fully ready for a stable commitment.
- Remove
@RestrictToonly after experimental annotations and API reviews are complete.
4. Critical Commands
| Task | Command |
|---|---|
| Format | ./gradlew :ktFormat or ./gradlew :ktCheckFile --format --file <path> |
| Build | ./gradlew :health:connect:connect-client:assemble |
| Update API | ./gradlew :health:connect:connect-client:updateApi |
| Unit Test | ./gradlew :health:connect:connect-client:test |
| Instrumentation Test | ./gradlew :health:connect:connect-client:connectedAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=<class> |
5. Testing Standards
- Emulator/Device Tests: Required for platform-delegated APIs. Use real devices or emulators with the latest system images.
- Suppression:
- Use
assumeTrue(Build.VERSION.SDK_INT >= X)for platform release features. - Use
assumeTrue(SdkExtensions.getExtensionVersion(Build.VERSION_CODES.U) >= Y)for extension features.
- Use
- Fakes: Always update
FakeHealthConnectClient.ktfor new APIs.
