Get Blob image and convert that image into Bitmap image

Question

I am getting image from database in blob format. i want to convert it into Bitmap image.the code i used to convert bitmap to Blob is put below.but please tell me how to reverse it.???

ByteArrayOutputStream boas = new ByteArrayOutputStream();  
btmap.compress(Bitmap.CompressFormat.JPEG, 100, boas ); //bm is the bitmap object   
byte[] byteArrayImage = boas .toByteArray(); 
String encodedImage = Base64.encodeToString(byteArrayImage, Base64.DEFAULT);

Answer 1

This will work

byte[] byteArray = DBcursor.getBlob(columnIndex);  

Bitmap bm = BitmapFactory.decodeByteArray(byteArray, 0 ,byteArray.length);

Answer 2

Why not make a helper method like that :)

public static Bitmap getBitmapFromBytes(byte[] bytes) {
        if (bytes != null) {
            return BitmapFactory.decodeByteArray(bytes, 0 ,bytes.length);
        }
        return null;
 }
