Android BitmapFactory can't decode inputstream -

i'm trying image webserver this:

@override     protected inputstream doinbackground(string... strings) {         inputstream stream = null;         try {             url url = new url(strings[0]);             httpurlconnection connection = (httpurlconnection) url.openconnection();             connection.connect();             stream = connection.getinputstream();             connection.disconnect();         } catch (malformedurlexception e) {             e.printstacktrace();         } {             return stream;         }     }      @override     protected void onpostexecute(inputstream stream) {         try {             bufferedinputstream buf = new bufferedinputstream(stream);             bitmap avatar = bitmapfactory.decodestream(buf);             user.avatar = avatar;             if (user.avatar != null)                 imgavatar.setimagebitmap(user.avatar);             buf.close();             stream.close();         } catch (ioexception e) {             e.printstacktrace();         }     } 

but bitmap avatar null. i've been looking through received inputstream via debugger, holds right url, , has fields httpengine/responsebodyin/bytesremaining holding number of bytes equals image size. image in .png format.

ok, solved using apache httpclient instead of httpurlconnection:

protected inputstream doinbackground(string... strings) {         httpresponse response = null;         inputstream instream = null;          try {             httpclient client = new defaulthttpclient();             httpget request = new httpget(new url(strings[0]).touri());             response = client.execute(request);             if (response.getstatusline().getstatuscode() != 200) {                 return null;             }             bufferedhttpentity bufhttpentity = new bufferedhttpentity(response.getentity());             instream = bufhttpentity.getcontent();              return instream;         }         catch (exception ex) {             return null;         }         {             if (instream != null) {                 try {                     instream.close();                 } catch (ioexception e) {                 }             }         }     }      @override     protected void onpostexecute(inputstream stream) {         bitmap avatar = bitmapfactory.decodestream(stream);         if (avatar != null) {             user.avatar = avatar;             imgavatar.setimagebitmap(avatar);         }     }
