This occurs using a few apks that make use of the camera (e.g., zxing, opencv). It displays a glitched image in the preview but it is still a function of what the camera se

Answer 1

For anyone using ZXing on their Glass, you can build a version from the source code with the above fix.

Add the following method into CameraConfigurationManager.java

  public void googleGlassXE10WorkAround(Camera mCamera) {
        Camera.Parameters params = mCamera.getParameters();
        params.setPreviewFpsRange(30000, 30000);
        params.setPreviewSize(640,360);
        mCamera.setParameters(params);
  }

And call this method immediately after anywhere you see Camera.setParameters() in the ZXing code. I just put it in two places in the CameraConfigurationManager and it worked.

I set the Preview Size to be 640x360 to match the Glass resolution.
