Android Http url connection Throwing File Not Found Exception at getInputstream

Question

I am trying to post some json string to a rest sever but I'm getting a java file not found exception at get input stream.

Here is my code:

package com.muzima.view.sample.activities;

import javax.servlet.http.HttpServletResponse;

import com.muzima.view.sample.R;

import android.app.Activity;
import android.content.Intent;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Base64;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.net.HttpURLConnection;
import java.net.URL;

public class SyncFormDataActivity extends Activity implements OnClickListener{

        private EditText value;

        private Button btn;

        private static final String METHOD_POST = "POST";

        private static final String URL = "/ws/rest/v1/muzima/queueData";



    @Override
        public void onCreate(Bundle savedInstanceState) {
                super.onCreate(savedInstanceState);
                setContentView(R.layout.activity_sync_form_data);

                String formsubmissionJson = getIntent().getStringExtra("formdata");
            String URF = (getString(R.string.default_server) + URL);

            System.out.println("url is" +URF);

                /* Testing to see if  we can get the json string from form in webview*/

                System.out.println("submit 56565 ======= " + formsubmissionJson);  

                btn=(Button)findViewById(R.id.button1);

                btn.setOnClickListener(this);

        }

        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
                getMenuInflater().inflate(R.layout.menu, menu);
                return true;

        }

        @Override
        protected void onDestroy() {
           super.onDestroy();

        }

        @Override
        protected void onResume() {
            super.onResume();

        }

        @Override
        protected void onPause() {
           super.onPause();
            }

        public void onClick(View v) {
        // TODO Auto-generated method stub
                String formsubmissionJson = getIntent().getStringExtra("formdata");
                new MyAsyncTask().execute(formsubmissionJson.toString());      

        }

        private class MyAsyncTask extends AsyncTask<String, String, String>{

        @Override
        protected void onPreExecute() {
           super.onPreExecute();

        }

        @Override
        protected String doInBackground(String... args) {
                try {
                                postingQueueData();
                        } catch (Exception e) {
                                // TODO Auto-generated catch block
                                e.printStackTrace();

                        }
                // TODO Auto-generated method stub
                        return null;
        }

        protected void onPostExecute(Double result){

        Toast.makeText(getApplicationContext(), "Form Data has been sent to server", Toast.LENGTH_LONG).show();

                // Start ListPatient activity
    Intent ip = new Intent(getApplicationContext(), ListPatientActivity.class);
       startActivity(ip);

        }


        public void postingQueueData() throws Exception   {
                    String formsubmissionJson = getIntent().getStringExtra("formdata");
                    URL url = new URL("http://192.168.1.3:8081/openmrs-standalone/ws/rest/v1/muzima/queueData");

                        HttpURLConnection connection = (HttpURLConnection) url.openConnection();
                    String encodedAuthorization = "Basic " + Base64.encodeToString("admin:test".getBytes(), Base64.NO_WRAP);
                   // String encodedAuthorization = "Basic " + Base64.encodeToString("admin:test".getBytes(), Base64.NO_WRAP);
                    connection.setRequestProperty("Authorization", encodedAuthorization);
                    connection.setRequestMethod(METHOD_POST);
                    connection.setRequestProperty("Content-Type", "application/json");
                    connection.setDoOutput(true);

                    OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
                    writer.write(formsubmissionJson);
                    writer.flush();

                    InputStreamReader reader = new InputStreamReader(connection.getInputStream(),"UTF-8");
                    int responseCode = reader.read();
                    if (responseCode == HttpServletResponse.SC_OK
                            || responseCode == HttpServletResponse.SC_CREATED) {
                        //log.info("Queue data created!");
                    }

                    reader.close();
                    writer.close();
                   }


                  }



        }

The system error I'm getting is as follows:

In case of 4** Error HTTP Codes use

connection.getErrorStream();

Instead of

connection.getInputStream();

connection is type of HttpURLConnection.

FileNotFound on URL connection means that target document is not available aka URL provided is wrong, or server returns 4* code. Check if target resource is available

If you are using inputStream than you want to RECEIVE something not SEND

Try setting this: connection.setDoOutput(false); to your connection - hope it helps ;)

add "connection.connect()" line before writing data to the stream.

connection.connect();

OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
                    writer.write(formsubmissionJson);                   
writer.flush();

I dont know why, but after adding the following line of code the problem was solved.

connection.setInstanceFollowRedirects(false);

If you used GET method on server side then it will give this error.

To make it works:

Change connection.setRequestMethod("POST"); to connection.setRequestMethod("GET"); and remove this following code.

connection.setDoOutput(true);       
            OutputStreamWriter writer = new OutputStreamWriter(connection.getOutputStream());
                    writer.write(formsubmissionJson);
                    writer.flush();

Or just simply change GET method to POST on server without doing changes above.
