Question

我收到的此味精语音未找到（没有这样的文件或目录）路径正确，这可能是错误的吗？

W/System.err: java.io.FileNotFoundException: /map.app.fileprovider/files/Pictures/JPEG_20190507_180502_4494360846236185755.jpg (No such file or directory)

如异常所示，该路径不存在！

作为一些建议，请尝试与异常作斗争，即使您确定，也要遵循它们！

无论如何这次是

val authorities = activity.packageName + ".fileprovider"

值得指责，因为您已在清单中以.provider后缀定义了提供程序。

因此更改为：

val authorities = activity.packageName + ".provider"

它应该通过更改而起作用。

干杯！
