android - Open file stored in SQLite as blob -

In the form of a title, I create a byte to store the file in Blob like this:
Byte [] Red_buf = myCursor.getBlob (1);
And I want to use FileOutputStream to open
I do not know how to do it Can anyone give me an example or website? ?

Can you really see instead of FileOutputStream? This is just an estimate because the question is not very clear
