First you need to first open the path to the External Storage folder, and then the directory where the gallery's images are stored. On most Android models, this is / mnt / sdcard / pictures, but I do not suggest hardcoding this way instead of using

 Environment.getExternalStorageDirectory(); 

After that, just create the file path in this directory and use outputStream to write your bitmap to this directory.
