Try this:

try{
   byte [] encodeByte=Base64.decode(encodedString,Base64.DEFAULT);
   Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
   return bitmap;
 }catch(Exception e){
   e.getMessage();
   return null;
 }

You are compressed image in JPEG please use PNG and try to convert in base64.

 b123.compress(Bitmap.CompressFormat.PNG, 100, baos);
