getSupportedSizeList() returned an empty list because mSupportedSize was not populated from native before the call, and the frame format filter excluded valid sizes. Use getSupportedSize() to populate the native size data first, then query with type=-1 to retrieve all supported sizes regardless of frame format. Also add CAMERA permission to the example app AndroidManifest and guard against empty size lists with a clear error message. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

camera.getSupportedSizeList()relies onmSupportedSizebeing populated from native viagetSupportedSize(), which was never called beforemCurrentFrameFormatwhich isn't set yet at that point, causing YUYV-only cameras (type:4) to be excluded<uses-permission android:name="android.permission.CAMERA" />, so the permission request silently failedTest plan
