android5.1版本调用摄像头扫描二维码功能失败

[pwdu1981]

最近开发一个扫描二维码的app，基于Google zxing实现，在android4.2版本中一切正常，但是将app安装到android5.1版本的手机上面进行二维码扫描时报出java.lang.SecurityException: Requires FLASHLIGHT or HARDWARE_TEST permission这样的错误，这个权限我已经在androidmanifest.xml中声明过了，但是为什么还是报这样的错误呢？谢谢！

你最后怎么结局的啊，我也遇到这个问题了

[hechaoanddingna]

楼主怎么解决的？知道的给个答案

[pwdu1981]

不好意思，好久没来，这个问题我最后发现是与手机型号有关的，我的手机不支持这个功能

楼主错了,是因为android 5.1 和 之前的android版本的权限机制不一样了
