我在一个问题 - 我需要阅读SecretKey的从安卓APK（如key.keystore），我的应用程序它必须被理解为一个FileInputStream，但是从资产我只得到的InputStream。如何为InputStream转换成的FileInputStream？或者有没有其他的办法，如何从存取权限，例如文件资源为一个FileInputStream？

I am in a problem - i need to read SecretKey from Android APK (e.g. key.keystore), for my app it has to be read as a FileInputStream, but from assets I am getting only inputStream. How to convert inputStream to FileInputStream? Or is there any other way, how to acces file from e.g. resources as a fileInputStream?

感谢

推荐答案

为什么需要一个FileInputStream具体一点吗？一般情况下，你不必关心的InputStream的底层实现，你只是从它读。也许的您的实施应该是不可知的InputStream

Why do you need a FileInputStream specifically? In general, you don't have to care about the underlying implementation of the InputStream, you just read from it. Maybe your implementation should be InputStream agnostic.
