i struggling today. after studying this: how put image attachment couchdb in android?

i got in end:

public static httpresponse makeupdaterequest(string uri, bitmap bmp) {     try {         httpput httpput = new httpput(uri);         bytearrayoutputstream stream = new bytearrayoutputstream();         bmp.compress(bitmap.compressformat.png, 0, stream);         bytearrayentity entity = new bytearrayentity(stream.tobytearray());         entity.setcontenttype("image/png");         entity.setchunked(true);         httpput.setentity(entity);         return new defaulthttpclient().execute(httpput);     } catch (unsupportedencodingexception e) {         e.printstacktrace();     } catch (clientprotocolexception e) {         e.printstacktrace();     } catch (ioexception e) {         e.printstacktrace();     }     return null; }

and called in floowing way:

    httpresponse updateresponse = makeupdaterequest(             appconfig.web_server_db_uri + uuid +              "/attachment?rev=" + revid, bmp);
