java - Base64 image data is not getting in android -

i using httpurlconnection connect server , response contains base64 image data. when trying read response using getinputstream not reading complete response, breaks in between. response contains list of objects in json format , each object contains base64 image data. reading breaks while trying read first image data first object. though not showing error displays till half of image data.how full response?? here code

inputstream = httpurlconnection.getinputstream();             byte[] b = new byte[1024];             stringbuffer buffer=new stringbuffer();             while ( is.read(b) != -1){                 buffer.append(new string(b));                 system.out.println("read= "+is.read());             } system.out.println(buffer); 

have tried example code google?

url url = new url("http://www.android.com/"); httpurlconnection urlconnection = (httpurlconnection) url.openconnection(); try {     inputstream in = new bufferedinputstream(urlconnection.getinputstream());     readstream(in); } {     urlconnection.disconnect(); } 

where readstream own method.

reading bufferedinputstream easier , faster.
