$ 你好，我正在使用我在 Github 上找到的应用程序https://github.com/simsor/SmartEyeglassQRCode/blob/master/AndroidApp/app/src/main/java/com/example/sony/smarteyeglass/extension/helloworld/ HelloWorldControl.java是索尼 SmartEyeglass 的二维码阅读器。但由于某种原因，它不起作用。当我扫描二维码时，它要么显示“未找到二维码”，要么显示“请稍候”很长时间，但从未显示结果。我尝试了一些东西，但没有任何改变。你们中有人知道发生了什么吗？
