java - Android，连续语音识别和错误IO异常

Question

我在 VR 连续播放方面遇到问题。在我的代码中有一个实现 VR 的 fragment 。

它可以工作，但有时我发现它在没有任何明显原因的情况下停止了。没有错误，没有崩溃，我可以通过点击按钮两次来重新启动。

日志没有帮助，这是我通过 LogCat 得到的

如你所见，VR启动了3次，最后一个周期由于IOEXCEPTION而停止

我们从这个github获取源代码https://github.com/fcrisciani/android-speech-recognition/tree/master/VoiceRecognition/src/com/speech/fcrisciani/voicerecognition

您可能正在处理许多错误。您需要捕获的第一个是 outstanding on the AOSP bug tracker for nearly a year .

我发布在 Google Product Forum about it here也有，但是没有任何反应。如果您正在阅读本文并希望解决这些问题，请为 AOSP 问题加注星标并在产品论坛帖子上发表评论以引起注意!

要解决此问题，您需要实现 such as the one demonstrated here .

您的特定错误已发布在 AOSP bug tracker here 上，但因与 Google 语音搜索有关而关闭。有人发帖regarding the bug on the Product Forum here ，但由于不活跃而关闭。

你无法让 Google 对这些事情采取任何行动，这是一个笑话。我想继续咆哮，但最好不要......
