Vuzix眼镜的Zxing库误差

Question

当我打电话给斑马线图书馆时，我正面临着撞车的危险，我眼镜的屏幕大小是428/240，这是我的简单电话。

    Intent i = new Intent(this, CaptureActivity.class);
    i.setAction("com.google.zxing.client.android.SCAN");
    i.putExtra("SCAN_MODE", "EAN_13,CODE_128");
    startActivityForResult(i, 0);

这就是我要犯的错误，

Answer 1

我对相机的PreviewSize进行了硬编码。在CameraConfigurationManager中，更改：

parameters.setPreviewSize(cameraResolution.x, cameraResolution.y);
//change into
parameters.setPreviewSize(1280, 720);

Answer 2

这是眼镜中的驱动程序或硬件错误，如堆栈跟踪所示。这与应用程序无关。您可以分析驱动程序错误，并可能向制造商报告。另外，尝试禁用应用程序中的“bug解决方案”选项，以避免常见的驱动程序错误。
