Solution 1
Did you declare the Internet permission in the AndroidManifest.xml?
You need to put the following into the AndroidManifest.xml
<manifest>
...
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
Solution 2
internet permission to your application by adding this under manifest
tag in your AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
otherwise Android will block internet traffic from your app

I am using the following code in android virtual Machine
try{ HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://10.0.2.2/ReadingFromServer.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); }catch(Exception e){ Log.e("log_tag", "Error in http connection"+e.toString()); }
I am getting the HttpHostConnectException. Dont know why? I have changed the address in the url from 127.0.0.1 to 10.0.2.2 but still getting that exception. I have wamp server installed in my computer and the file "ReadingFromServer.php" is placed in "www" folder.
Here is the complete stack trace
