Android: Java Net Socket Exception inside AsyncTask

Question

I am getting the following exception when i run my android app: I am getting inside the asynctask but logging this exception.

03-15 16:49:21.456  16854-16892/com.ashwinbhy.phpwrite W/Ashwin﹕ java.net.SocketException: socket failed: EACCES (Permission denied)

I have included this permissions inside my manifest.xml:

<uses-permission android:name="android.permission.internet"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.access_network_state"/>

The code is:

 try {

                URL url = new URL("http://10.0.0.2/tt.php");
                HttpURLConnection conn = (HttpURLConnection) url.openConnection();
                conn.setReadTimeout(10000);
                conn.setConnectTimeout(15000);
                conn.setRequestMethod("POST");
                conn.setDoInput(true);
                conn.setDoOutput(true);

                Uri.Builder builder = new Uri.Builder()
                        .appendQueryParameter("bus_id", busid)
                        .appendQueryParameter("lat", lat)
                        .appendQueryParameter("lon", lon);

                String query = builder.build().getEncodedQuery();

                OutputStream os = conn.getOutputStream();
                BufferedWriter writer = new BufferedWriter(
                        new OutputStreamWriter(os, "UTF-8"));
                writer.write(query);
                writer.flush();
                writer.close();
                os.close();

                conn.connect();
            }
            catch(Exception e){
                Log.w("Ashwin",e.toString()+"inside the exception log");
                return "error";
            }

Try putting proper case for permissions. They are case sensitive.

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Update

Your IP is also wrong. It should be, 10.0.2.2. So your URL will become,

http://10.0.2.2/tt.php

It should work fine on the emulator.
