Passing Parameters with HttpURLConnection

Question

With the old Apache stuff deprecated in API 22, I am finally getting around to updating my network stuff.

Using openConnection() seems pretty straight forward. However, I have not seen any good example to send parameters with it.

How would I update this code?

        ArrayList<NameValuePair> param = new ArrayList<NameValuePair>();
        param.add(new BasicNameValuePair("user_id",String.valueOf(userId)));
        httpPost.setEntity(new UrlEncodedFormEntity(param));

Now that NameValuePair and BasicNameValuePair are also deprecated.

EDIT: My server side php code doesn't expect JSON parameters and I can't all of the sudden switch due to existing users -- so a non-JSON answer is recommended.

EDIT2: I just need to Target Android 4.1+ at the moment.

if you want to maintain minSdk version , maybe it's not problem to use deprecated methods. – Lamkin

Well I only need to target Android 4.1+ at the moment, if there is a one solution that fits all, and does not use deprecated stuff, that is what I would like to do. Also, I am OCD, I don't like lines going thru my code telling me things are deprecated.. – Paleface

You can use annotations like @SuppressLint or ` @TargetApi(22)` to use newer library, and use @suppresswarnings to clear that warnints. I think that would't be bad decision. – Lamkin

I know, I know, I don't like those either. :D Usually something is deprecated for a reason, so I would like to update when possible. And in this case, Google recommended this change like 3 years ago. – Paleface

I also hate the tricking with code like this, but sometimes it's inevitable. Hope you find your answer, good luck! – Lamkin

Answer 1

I fixed it like this:

       HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");

Here is parameter stuff:

        String charset = "UTF-8";
        String s = "unit_type=" + URLEncoder.encode(MainActivity.distance_units, charset);
        s += "&long=" + URLEncoder.encode(String.valueOf(MainActivity.mLongitude), charset);
        s += "&lat=" + URLEncoder.encode(String.valueOf(MainActivity.mLatitude), charset);
        s += "&user_id=" + URLEncoder.encode(String.valueOf(MyndQuest.userId), charset);

        conn.setFixedLengthStreamingMode(s.getBytes().length);
        PrintWriter out = new PrintWriter(conn.getOutputStream());
        out.print(s);
        out.close();
