HTTP Get/Post on Android doesn't work with Google Apps Script

Question

I wrote a Google Apps script that receives data and stores them on a spreadsheet, something like this:

https://script.google.com/macros/s/.../exec?t1=hi&t2=foo

The URL works fine on the browser and the data is indeed stored. However, when I try to implement this from an Android app, it doesn't work. I've tried both HttpGet and HttpPost techniques in an AsyncTask and got nothing. This is the code for the HttpPost:

class sendData extends AsyncTask<String, Void, String> {



    @Override
    protected String doInBackground(String... params) {

        String [] data = params[0].split("-");

        postData(data[0],data[1]);

    }      

    @Override
    protected void onPostExecute(String result) {    
      // Update Ui here  

    }

    public void postData(String l1, String l2) {
        // Create a new HttpClient and Post Header
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("https://script.google.com/macros/s/.../exec");

        try {
            // Add your data
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("test", l1));
            nameValuePairs.add(new BasicNameValuePair("testt", l2));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

        } catch (ClientProtocolException e) {
            // TODO Auto-generated catch block
        } catch (IOException e) {
            // TODO Auto-generated catch block
        }
    } 

}

Where could the problem be? I've set the privacy of both the script and the spreadsheet to be accessible and editable by anyone and still no response.

Here's the logcat. Not sure if it means something:

Answer 1

I bet you haven't published the appscript service as public and anonymous. Also make sure to use ContentSevice.

Answer 2

I found out another "Less coding" way to get my Google Apps script to read my input, using URL and HttpURLConnection.openConnection() :

try {
  URL url = new URL("https://script.google.com/macros/s/.../exec?t1=hi&t2=foo");
  HttpURLConnection con = (HttpURLConnection) url
    .openConnection();
  readStream(con.getInputStream());
  } catch (Exception e) {
  e.printStackTrace();
}



private void readStream(InputStream in) {
  BufferedReader reader = null;
  try {
    reader = new BufferedReader(new InputStreamReader(in));
    String line = "";
    while ((line = reader.readLine()) != null) {
      System.out.println(line);
    }
  } catch (IOException e) {
    e.printStackTrace();
  } finally {
    if (reader != null) {
      try {
        reader.close();
      } catch (IOException e) {
        e.printStackTrace();
        }
    }
  }
}

However for HttpGet and HttpPost, Zig's ContentService was the way to go. I included the return in either doGet() or doPost() in the Google script as the following:

return ContentService.createTextOutput('Success');
