Chetan,
As already pointed out in one of the other threads, you will have to use standard
Java I/O for this. Reading/Writing from/to files is not any different on Android.
Anyways, here is what you can do:
1. Create an abstraction for the file in your application. (Use
java.io.File)
2. Open this file in
FileInputStream(use appropriate constructor of
java.io.FileInputStream)
3. Pass this FileInputStream object to
BitmapFactory.decodeStream(FileInputStream); to create a Bitmap.
Hope that helps.
