I want to display the other keypoints but Array 'outputJoints' isn't the true coordinate

could you help me?

hi, if you want to print the outputJoints , you might need to build the matrix for transforming the hand landmark joints, you might refer to DetectortActivity

   frameToCropTransform =
        ImageUtils.getTransformationMatrixContain(
            previewWidth, previewHeight,
            cropSize, cropSize,
            sensorOrientation, MAINTAIN_ASPECT);

    cropToFrameTransform = new Matrix();
    frameToCropTransform.invert(cropToFrameTransform);

The logic of hand landmark detection is it cut the hand from the original bitmap and using model to do recognition.

This above matrix is using for the palm detection. You need to create a new matrix for transforming all the output joint to corresponding ratio
