How do I decode a png image encoded in Base64 and see it on an ImageView?

Question

My android device requests to the server a png image. The server encodes the image in Base64 and sends it to my device. After that, I decode the Base64 string into a byte array and use BitmapFactory.decodeByteArray() to make a Bitmap image of it. I can't see the image when I add it in an ImageView.

See below for the code:

JSONObject params = resultObject.getJSONObject("params");
byte[] decodedImageInBytes = Base64.decode(params.getString("image_one"), Base64.DEFAULT);

Bitmap myImage = BitmapFactory.decodeByteArray(decodedImageInBytes, 0, decodedImageInBytes.length);
ImageView imageViewOne = (ImageView) findViewById(R.id.imageViewOne);
imageViewOne.setImageBitmap(myImage);

Edit:

It seems that my code is okay, I have some problems with the server. Thanks everyone!

I understand that. Could you post an example of such a base64 string? — Matt Ball, Apr 06 '12 at 20:18
Why are you using base64? You could load it binary without problems — stefan bachert, Apr 06 '12 at 20:21
@stefanbachert it's coming through JSON, so presumably it's being sent over HTTP. — Matt Ball, Apr 06 '12 at 20:21
has you bitmap a valid height and width after decoding? I have been decoding base64 images exactly like you without any problems. — Renard, Apr 06 '12 at 20:24
Agreed with @Renard. Your code looks fine (as per http://stackoverflow.com/a/4837293/139010 and http://stackoverflow.com/q/5106670/139010) so my guess is that the data is corrupted or not in the expected format. — Matt Ball, Apr 06 '12 at 20:27
I have posted the string. I'm not sure if the height and width is correct... — Aerial, Apr 06 '12 at 20:28
@Xonarial : decode your string http://www.base64decode.org/ and see what it content — ρяσѕρєя K, Apr 06 '12 at 20:32
welcome,but say thanks to @MДΓΓ БДLL and ask for answer i think — ρяσѕρєя K, Apr 06 '12 at 20:36

I have decoded your string for you. It is not bitmap data.

Yep, I just saw that too. :D Thanks for your help tough! – Aerial Apr 06 '12 at 20:31 — Aerial, Apr 06 '12 at 20:31
