Image not created using BitmapFactory.decodeByteArray

Edit: When I save these bytes in a txt file, and when I save it as a png file, it shows an image, but it doesn't work here, why ...?

I use this code to create an image from an array of bytes on doInBackground ()

String base64data=StringEscapeUtils.unescapeJava(IOUtils.toString(resp.getEntity().getContent()));
base64data=base64data.substring(1,base64data.length()-1);
JSONObject obj=new JSONObject(base64data);
JSONArray array=obj.getJSONArray("EMRTable");
JSONObject childobj=array.getJSONObject(0);
results=childobj.getString("DocumentInternalFormat");

and onPostExecute

if(jsondata!=null) {
    receiveData(jsondata);
}

There is no error in logcat, even there is no exception ... but the image is not displayed. I also liked

String data=(String)object;
data=data.trim();
byte[] base64converted=Base64.decode(data,Base64.DEFAULT);          

ImageView image=new ImageView(context);
image.setImageBitmap(bmp);
setContentView(image);

but the result of the image is not displayed, but there is no exception or error, what is the problem ...

Numbered lines are when I try to save these bytes in a text file, and when I pull out the file, it displays the images using the default Windows image viewer.

BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
BitmapFactory.decodeByteArray(base64converted,0,base64converted.length,options);

// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, 500, 500);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
Bitmap bmp1=BitmapFactory.decodeByteArray(base64converted,0,base64converted.length,options);
