I am trying to test my android app and add data to the database hosted on localhost. I opened a tunnel using ngrok to access the database stored on my local computer. Here is my code:
public class MainActivity extends FragmentActivity{
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private static String email;
// nav drawer title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
private static final int RESULT_SETTINGS = 1;
private static String IP_ADDRESS="http://682dc364.ngrok.com/";

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);
Account[] accounts = AccountManager.get(getBaseContext()).getAccounts();
if(accounts.length > 0)
email = accounts[0].name;
Toast.makeText(this, email, Toast.LENGTH_SHORT).show();
mTitle = mDrawerTitle = getTitle();
addUser();
}
private static void addUser()
{
HashMap<String, String> nameValuePairs = new HashMap<String, String>();
nameValuePairs.put("email",email);
String id="addUser";
AsyncHttpPost asyncHttpPost = new AsyncHttpPost(nameValuePairs);
asyncHttpPost.execute(id,"http://"+IP_ADDRESS+"/MakeMyDay/add_user.php");
}

Does anyone know why this isn't working
