java - Android HttpURLConnection POST Request with image/jpeg -

-

i trying send image in post request httpurlconnection. have next code:

string i3 = string.valueof(system.currenttimemillis()); bytearrayoutputstream i4 = new bytearrayoutputstream(); i4.write(("--" + i3 + system.lineseparator()         + "content-disposition: form-data; name=\"" + i1.this.i2 + "\"; filename=\"" + i1.this.i2 + ".jpg\"" + system.lineseparator()         + "content-type: image/jpeg" + system.lineseparator()         + "content-length: " + string.valueof(i2.this.i1.length) + system.lineseparator() + system.lineseparator()).getbytes()); i4.flush(); i4.write(i2.this.i1); i4.flush(); i4.write((system.lineseparator() + system.lineseparator() + "--" + i3 + "--").getbytes()); i4.flush(); i4.close(); httpurlconnection i5 = (httpurlconnection) new url(myurl).openconnection(); i5.setrequestmethod("post"); i5.setdooutput(true); i5.setrequestproperty("user-agent", "mozilla/5.0"); i5.setrequestproperty("content-type", "multipart/form-data; boundary=" + i3); i5.setfixedlengthstreamingmode(i4.tobytearray().length); i5.connect(); outputstream i6 = i5.getoutputstream(); i6.write(i4.tobytearray()); i6.flush(); i6.close(); system.out.println(i5.getresponsecode() + " " + i5.getresponsemessage()); i5.disconnect();

but when i'm trying response code/message of connection application throws me exception:

07-28 12:15:00.722: java.io.ioexception: unexpected end of stream on connection{123.456.789.012:80, proxy=direct@ hostaddress=123.456.789.012 ciphersuite=none protocol=http/1.1} (recycle count=0)

maybe problem post request bad or having syntax errors? can me , what's wrong, please.

i tested code on java application on windows! result of request 200 ok. conclusion: wrong android! still don't know concretically.

i found solution! ugly strings system.lineseparator() need replaced old kind \r\n! great.
