             .getBitmap(cr, selectedImage);

            imageView.setImageBitmap(bitmap);


            ByteArrayOutputStream stream= new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
            byte imginbyte[]=stream.toByteArray();
            byte temp[]=imginbyte;

            myDb.execSQL("INSERT INTO tableimage VALUES('"+temp+"');");
            Cursor c= myDb.rawQuery("SELECT * FROM tableimage", null);
            c.moveToLast();
            byte asd[]= c.getBlob(c.getColumnIndex("imgpath"));
            byte img[]=null;

          //  BitmapFactory.decodeByteArray(asd, 0, asd.length);
            ImageView iv=(ImageView)findViewById(R.id.img2);
            ImageView iv1=(ImageView)findViewById(R.id.img3);

            iv.setImageBitmap( BitmapFactory.decodeByteArray(asd, 0, asd.length));
            iv1.setImageBitmap( BitmapFactory.decodeByteArray(asd, 0, asd.length));

Answer 1

Try this

ByteArrayInputStream imageStreamFront = new ByteArrayInputStream(asd);

Bitmap bitFrontImage = BitmapFactory.decodeStream(imageStreamFront);

if(bitFrontImage!=null)
{
   iv.setImageBitmap(bitFrontImage, 40);
}

Without blob store image and retrive. with string database see below code

bitmap = android.provider.MediaStore.Images.Media
             .getBitmap(cr, selectedImage);
            imageView.setImageBitmap(bitmap);

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

            myDb.execSQL("INSERT INTO imgtbl VALUES('"+encodedImageString+"');");
            Cursor c= myDb.rawQuery("SELECT * FROM imgtbl", null);

           c.moveToFirst();
           String img=c.getString(0);
           byte[] byarray = Base64.decode(img, Base64.DEFAULT);
           Bitmap bmimg = BitmapFactory.decodeByteArray(byarray, 0,
                   byarray.length);

            ImageView iv=(ImageView)findViewById(R.id.img2);
            ImageView iv1=(ImageView)findViewById(R.id.img3);

            iv.setImageBitmap(bmimg);
            iv1.setImageBitmap(bmimg);
