How can I read the content of a file if I have a ParcelFileDescriptor

In android, I get a ParcelFileDescriptor after 开发者_高级运维I call mContext.getContentResolver().openFileDescriptor(contentURI, "r")

but how can I read the content of the file into a string or Stringbuffer?

Thank you.

I would recommend that you use openInputStream() on ContentResolver instead. Then, you just use normal Java I/O to read it in.
