Issue in Covert from String Base64 to Bitmap

Question

Code stuff for convert from Bitmap to String Base64

Bitmap thumbnail = extras.getParcelable("data");
ByteArrayOutputStream baos = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, baos);
thumbnail.recycle();
byte[] b = baos.toByteArray();
String attachment = Base64.encodeToString(b, Base64.DEFAULT);

Code stuff for convert from String Base64 to Bitmap

byte[] encodeByte = Base64.decode(strBase64, Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
imageView.setImageBitmap(bitmap);

but i get bitmap = null;

I also refer Base64 to Bitmap to display in ImageView

Thanks in advance.

show your encoding code, you are decoding it correctly – Neal Ahluvalia Jun 26 '15 at 05:19 — Neal Ahluvalia, Jun 26 '15 at 05:19

  // convert Bitmap to String
    public static String BitMapToString(Bitmap bitmap) {
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
        byte[] arr = baos.toByteArray();
        imageData = Base64.encodeToString(arr, Base64.DEFAULT);
        return imageData;
    }

    // Convert String to Bitmap
    public static Bitmap StringToBitMap(String image) {
        try {
            byte[] encodeByte = Base64.decode(image, Base64.DEFAULT);
            Bitmap bitmap = BitmapFactory.decodeByteArray(encodeByte, 0,
                    encodeByte.length);
            return bitmap;
        } catch (Exception e) {
            e.getMessage();
            return null;
        }
    }

I put String Base64 in web view with HTML format then its work fine, but not work in above code — Palak, Jun 26 '15 at 11:07

You are calling thumbnail.recycle(); after loading bitmap,, either remove it or call before loading bitmap
