php is not receiving data from android through httpUrlConnection - php

Question

I am sending user email from Android app to PHP using HttpUrlConnection but PHP is not receiving Any data from App. This type of questions have already been asked but their solution do not worked for me. My Android Coding is
URL server_url = new URL("http://www.myURL.com/Jobs/login.php");
HttpURLConnection urlc = (HttpURLConnection) server_url.openConnection();
urlc.setDoOutput(true);
urlc.setDoInput(true);
urlc.setRequestMethod("POST");
urlc.setRequestProperty("Content-Language", "en-US");
urlc.setRequestProperty("Accept-Encoding", "identity");
urlc.connect();
HashMap<String, String> param = new HashMap<>();
param.put("email", mEmail);
DataOutputStream os = new DataOutputStream(urlc.getOutputStream());
os.writeBytes(URLEncoder.encode(mEmail, "UTF-8"));
os.flush();
os.close();
and My php code is:
<?php
$user_email=$_POST['email'];
echo "Email is $user_email";
?>
but when running this php on browser, it is echoing "Email is" as it is not receiving any data from android. Please Help
My php code contains only these two lines. Am I missing something in php coding?

You're not sending the paramater at all. You need to structure the request much better aswell since it's clear you're getting confused.
URL server_url = new URL("http://www.myURL.com/Jobs/login.php");
HttpURLConnection urlc = (HttpURLConnection) server_url.openConnection();
//header stuff
urlc.setRequestMethod("POST");
urlc.setRequestProperty("Content-Language", "en-US");
urlc.setRequestProperty("Accept-Encoding", "identity");
//params
String urlParameters = "email="+mEmail;
//send post
urlc.setDoOutput(true);
DataOutputStream wr = new DataOutputStream(urlc.getOutputStream());
wr.writeBytes(urlParameters);
wr.flush();
wr.close();
//read result
BufferedReader in = new BufferedReader(
new InputStreamReader(urlc.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = in.readLine()) != null) {
response.append(inputLine);
}
in.close();
//print result
System.out.println(response.toString()
);
