 {
 Uri selectedImage = data.getData();
 Cursor cur = PhotoImage.this.managedQuery(selectedImage, null, null, null, null);
 if(cur.moveToFirst())
 {
 long Length = cur.getLong(cur.getColumnIndex(ImageColumns.SIZE));
 try{
 String Image=Base64.encodeBytes(selectedImage.getPath().getBytes());
 Log.v("check",Image);
 byte[] bytedata = new byte[(int) Length];
 FileOutputStream fos=new FileOutputStream(Img);
 fos.write(bytedata[0]);
 fos.close();

This code will convert image file into bytes:

FileInputStream fin = c.openFileInput(path of file);
byte[] imageBytes = new byte[fin.available()];
fin.read(imageBytes);

put this in try...catch()

Try this and let me know if you are asking the same or some thing else.
