关于SDK Demo集成素材加载异常、custom timeline缺失及相关技术实现的问询

Hey there, let's tackle your concerns one by one based on your experience with the SDK integration:

1. Issues Encountered Post-Integration #

• Cannot retrieve assets from Huawei App Gallery section:
  First, double-check that you’ve correctly configured App Gallery access permissions in your project’s manifest file, and confirm your API keys are properly linked to the SDK. Also, verify that the target assets are published and region-enabled in your Huawei App Gallery console—unpublished or region-restricted assets won’t be accessible via the SDK.
• Missing Custom Timeline feature (implemented in UI SDK but not in Demo + no documentation):
  Since the UI SDK already includes this functionality, reach out directly to the SDK’s support team to request official documentation for the custom timeline implementation. If you need a temporary workaround (and licensing permits), you can inspect the UI SDK’s compiled code to reverse-engineer core logic, but official docs are always the reliable path.

2. Additional Customization Questions #

• Loading local assets:
  Place your media files in your project’s assets directory, then use the SDK’s built-in asset loader API (typically something like SDKAssetLoader.loadLocalAsset("path/to/your/asset")) to reference them. Ensure your build configuration (e.g., Gradle for Android) explicitly includes the assets folder in the source set, and double-check file paths for typos.
• Transition and animation patterns for custom effects:
  Most SDKs expose lifecycle hooks or animation interfaces for custom transitions. Look for methods like registerTransitionListener() or classes such as CustomTransitionAnimator in the core SDK library. You can define custom animation curves using interpolators (like AccelerateDecelerateInterpolator) and bind them to timeline events (e.g., clip start/end points). Start with simple transitions to validate integration before building complex effects.

3. Observations on the SDK Demo Project #

I noticed two gaps in the provided SDK Demo project:

• Some assets fail to load, likely due to missing local files or incorrect remote asset configuration in the demo’s setup
• No implementation of the custom timeline feature, which is inconsistent with the UI SDK’s stated capabilities
