Do not assume a Camera2 buffer is contiguous NV21 based only on width and height. Read according to the image format and each plane's rowStride and pixelStride. Define rotation, mirroring and when asynchronous processing finishes. This is a project and documentation review, not an Android release announcement.
What the documentation establishes
Android's ImageFormat reference and Image.Plane API describe YUV_420_888 and plane strides. Read values returned by the target device instead of assuming another phone or board has the same layout. No additional device compatibility testing is reported here.
SDK input checklist
| Item | Inputs to record | Failure checks |
|---|---|---|
| Format and planes | Format, dimensions, plane strides and crop region | Use edge-pattern samples to check row errors, color errors and out-of-bounds access |
| Rotation and mirroring | Sensor orientation, display orientation and front-camera mirroring | Check portrait/landscape and left/right; test coordinate mapping separately |
| Lifetime | Responsibility for retaining, copying, submitting and releasing Image data | Asynchronous work must not read released or invalid buffers |
| Queue and load | Capture rate, submission rate, backlog and dropping policy | Record latency and buffer release during sustained input |
| Output coordinates | Transform between model input and preview region | Check boxes against samples at known positions |
Organizing integration validation
Start with one specified device and input mode. Save input metadata and publishable samples, then test conversion, orientation and coordinates. Add other resolutions and sustained capture afterward. Exclude conversion and lifetime errors before attributing changed results to the algorithm.
Published project boundaries
The published vision SDK project record in Chinese covers offline face detection, orientation assessment and Camera2 integration on RK3588 Android. Detection is not identity recognition. The CPU path does not establish NPU acceleration or compatibility with all Android devices. Provide target hardware, system, samples and SDK requirements when assessing the original Chinese Android development service, then agree a device matrix.
