abstract class SessionConfigCamera2Interop : CameraDeviceInterop, SessionConfigurationInterop, CameraCaptureSessionInterop

---

Configures Camera2 options on a androidx.camera.core.SessionConfig.

Provides setters for session parameters, operating mode session type, session color space, device and session state callbacks, capture request keys, and repeating capture callbacks.

Warning: Callbacks configured on this target receive raw android.hardware.camera2.CameraDevice and android.hardware.camera2.CameraCaptureSession instances. Directly invoking state-altering, lifecycle, or request-submitting methods on these raw objects bypasses CameraX pipeline management and causes state desynchronization, stream freezing, or crashes. Do not invoke:

• On android.hardware.camera2.CameraDevice: android.hardware.camera2.CameraDevice.close or session creation methods (android.hardware.camera2.CameraDevice.createCaptureSession, android.hardware.camera2.CameraDevice.createCaptureSessionByOutputConfigurations, android.hardware.camera2.CameraDevice.createReprocessableCaptureSession, android.hardware.camera2.CameraDevice.createExtensionSession)

• On android.hardware.camera2.CameraCaptureSession: lifecycle methods (android.hardware.camera2.CameraCaptureSession.close, android.hardware.camera2.CameraCaptureSession.abortCaptures, android.hardware.camera2.CameraCaptureSession.stopRepeating), request submission methods (android.hardware.camera2.CameraCaptureSession.setRepeatingRequest, android.hardware.camera2.CameraCaptureSession.setRepeatingBurst, android.hardware.camera2.CameraCaptureSession.capture, android.hardware.camera2.CameraCaptureSession.captureBurst), or surface configuration methods (android.hardware.camera2.CameraCaptureSession.updateOutputConfiguration, android.hardware.camera2.CameraCaptureSession.finalizeOutputConfigurations, android.hardware.camera2.CameraCaptureSession.prepare, android.hardware.camera2.CameraCaptureSession.switchToOffline)
