| <p>HIDL interface methods that interact with the camera must generate |
| the corresponding camera specific |
| <a href="https://source.android.com/reference/hidl/android/hardware/camera/common/1.0/types">status</a>.</p> |
| <p>If |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#notify">ICameraDeviceCallbacks::notify()</a> |
| is called with |
| <a href="https://source.android.com/reference/hidl/android/hardware/camera/device/3.2/types#errorcode">ERROR_DEVICE</a>, |
| only the |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceSession#close">ICameraDeviceSession::close()</a> method can be called successfully. All other |
| methods will return |
| <a href="/reference/hidl/android/hardware/camera/common/1.0/types#status">INTERNAL_ERROR</a>.</p> |
| |
| <p>Transient errors in image capture must be reported through |
| <a href="https://source.android.com/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#notify">ICameraDeviceCallbacks::notify()</a> |
| with the appropriate |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/types#errorcode">error code</a>. |
| In each transient failure case, the HAL must still call |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#processcaptureresult">ICameraDeviceCallbacks::processCaptureResult()</a> |
| with an appropriate |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/types#captureresult">capture result</a>.</p> |

| <h2 id="stream-mgmt">Stream management</h2> |
| <h3 id="configure_streams">configure_streams</h3> |
| <p>HAL clients must configure camera streams by calling |
| <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceSession#configurestreams">ICameraDeviceSession::configurestreams()</a>.</p> |
