Sending blob or byte array in XML

android, jakarta-ee, java, xml, xmlhttprequest

Solution

First of all. Convert your Bitmap into ByteArray and then Convert that byte array to Base64 String format and send that Base64 String format in xml.

ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bmp.compress(CompressFormat.PNG, 0 , baos); //bmp is the bitmap object   
byte[] b = baos.toByteArray(); 
String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);

Now send `encodedImage` in your xml...

Base64 to bitmap conversion

public static Bitmap convertByteArrayToBitmap(String Base64String) 
{
    byte[] data = Base64.decode(Base64String, Base64.DEFAULT);
    Bitmap bitmap = BitmapFactory.decodeByteArray(data , 0, data.length);
    return bitmap;
}

Problem

I am a novice back end developer. I am developing a REST webservice. My requirement is to send BLOB content from the server to Mobile Side. My douubt is, is it possible to send BLOB in XML or should I convert it into ByteArray and send it?
