使用手电筒后无法使用条形码扫描仪

Posted 2023-03-07

【中文标题】使用手电筒后无法使用条形码扫描仪

【英文标题】：Unable to use barcodescanner after using torch

【发布时间】：2013-03-29 21:48:26

【问题描述】：

我使用的是 Phonegap 2.5，并且我已经下载了最新版本的 BarcodeScanner 和 Torch。如果我使用手电筒然后尝试扫描图像，我会收到“抱歉，android 相机遇到问题。您可能需要重新启动设备。”。我在想手电筒并没有松开手电筒。如果您同意这是问题所在，任何人都知道强制它释放的方法吗？

【问题讨论】：

我也有同样的问题，你有没有发现如何同时使用这两种方法？

是的。我今晚回家后会发布一个修复程序。我刚看到这个。对不起。

如果可以，那就太好了

【参考方案1】：

尝试使用这个 phonegap 插件代替普通的条码扫描器。
