Hi all,

I have an audio file. I am maintaining that audio file in FileDescriptor. I want to write that file in sdcard or somewhere else.
I do not know how to copy that file using filedecriptor.

What I have done so far is ..


Where memo path is just a name of file.
Can ayonr give some idea.

Here are the docs on writing to the SD card: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal
You will also need this permission in the manifest:


As far as reading the file when you have a FileDescriptor, several of the java.io classes take FileDescriptors as constructor parameters, including FileReader and FileInputStream.
