| <p>与相机交互的 HIDL 接口方法必须生成相应的相机特定<a href="https://source.android.com/reference/hidl/android/hardware/camera/common/1.0/types">状态</a>。</p> |
| <p>如果调用了 <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#notify">ICameraDeviceCallbacks::notify()</a> 且返回 <a href="https://source.android.com/reference/hidl/android/hardware/camera/device/3.2/types#errorcode">ERROR_DEVICE</a>，则只能成功调用 <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceSession#close">ICameraDeviceSession::close()</a> 方法。其他所有方法都将返回 <a href="/reference/hidl/android/hardware/camera/common/1.0/types#status">INTERNAL_ERROR</a>。</p> |

| <p>图像拍摄过程中的瞬时错误必须通过 <a href="https://source.android.com/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#notify">ICameraDeviceCallbacks::notify()</a> 进行报告且返回相应的<a href="/reference/hidl/android/hardware/camera/device/3.2/types#errorcode">错误代码</a>。在发生各种瞬时失败的情况下，HAL 必须仍然调用 <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceCallback#processcaptureresult">ICameraDeviceCallbacks::processCaptureResult()</a> 且返回相应的<a href="/reference/hidl/android/hardware/camera/device/3.2/types#captureresult">捕获结果</a>。</p> |

| <h3 id="configure_streams">configure_streams</h3> |
| <p>HAL 客户端必须通过调用 <a href="/reference/hidl/android/hardware/camera/device/3.2/ICameraDeviceSession#configurestreams">ICameraDeviceSession::configurestreams()</a> 来配置相机信息流。</p> |
