Effective in 2026, to align with our trunk stable development model and ensure platform stability for the ecosystem, we will publish source code to AOSP in Q2 and Q4. For building and contributing to AOSP, we recommend utilizing android-latest-release instead of aosp-main. The android-latest-release manifest branch will always reference the most recent release pushed to AOSP. For more information, see Changes to AOSP.
Error and stream handling Stay organized with collections Save and categorize content based on your preferences.
Error management
HIDL interface methods that interact with the camera must generate the corresponding camera-specific status.
If ICameraDeviceCallbacks::notify() is called with ERROR_DEVICE, only the ICameraDeviceSession::close() method can be called successfully. All other methods will return INTERNAL_ERROR.
Transient errors in image capture must be reported through ICameraDeviceCallbacks::notify() with the appropriate error code. In each transient failure case, the HAL must still call ICameraDeviceCallbacks::processCaptureResult() with an appropriate capture result.
Stream management
HAL clients must configure camera streams by calling ICameraDeviceSession::configurestreams().
