GetWebpageContent.js

var message;
 
//Called when application is started. 
function OnStart() 
{ 
    //Create a layout with objects vertically centered. 
    lay = app.CreateLayout( "linear", "VCenter,FillXY" ); 
 
    //Create a button to send request. 
    btn = app.CreateButton( "Get message", 0.3, 0.1 );
    btn.SetOnTouch( btn_OnTouch );  
    lay.AddChild( btn );  
    //Add layout to app.     
    app.AddLayout( lay ); 
 
}    
 
//Handle button press. 
function btn_OnTouch()  
{  
  //Send request to remote server. 
  var url = "http://droidscript.sgarman.net/message.txt" 
  SendRequest( url  ); 
} 
 
//Send an http get request. 
function SendRequest( url ) 
{

    httpRequest.onreadystatechange = function() { HandleReply(httpRequest); };   
    httpRequest.open("GET", url, true); 
    httpRequest.send(null); 
 
    app.ShowProgress( "Loading..." );

//Handle the server's reply (a json object). 
function HandleReply( httpRequest ) 
{ 
    if( httpRequest.readyState==4 ) 
    { 
        //If we got a valid response.

        { 
            message = httpRequest.responseText;
            app.Alert( message );
        } 
        //An error occurred

    } 
  app.HideProgress();
