This means that third-party apps can support users with Android 8, but only users with Android 9 or higher can use Health Connect.\n\nArchitecture components\n-----------------------\n\n**1. Software development kit**\n\nThe SDK enables the client app to communicate with the Health Connect APK, over IPC.\n\n**2. Client app**\n\nTo integrate with Health Connect, client apps link the SDK into their health and fitness app. This provides an API surface that facilitates interaction with the Health Connect API.\n\n**3. Health Connect APK**\n\nThe Health Connect APK is the main substance of the Health Connect API, and contains both its Permissions Management and Data Management components. The Health Connect APK is made available directly on the user's device.\n\n**4. Permissions management**\n\nHealth Connect includes a user interface through which apps request a user's permission to display data.\n\nIt also provides a list of existing user permissions, allowing users to easily control access to data across multiple applications.\n\n**5. Data management**\n\nHealth Connect provides a user interface with an overview of recorded data, whether it's a user's step count, cycling speed, heart rate, or any other [supported data types](https://developer.android.com/reference/kotlin/androidx/health/connect/client/records/package-summary#classes)."]]
