Backup your apps

Following a reminder from Dave on the discussion group that we should be backing up our apps regularly, I thought I would post a simple way of sending yourself an email archive of your DroidScript folder.

The following code is intended as a guide to one way you can keep a snapshot of your code at any given time.

You may well find the archiving code more useful than the email code.

var mygmail = "";
var mypass = "mypassword";
//Called when application is started.
function OnStart()
    //Create a layout with objects vertically centered.
    lay = app.CreateLayout( "linear", "FillXY" );    
    //Create a text label and add it to layout.
    txt = app.CreateText( "..." );
    lay.AddChild( txt );
    //Add layout to app.    
    app.AddLayout( lay );
    var fname = CreateArchive();
    sendGmail( mygmail, mypass, fname);
//Create a backup archive.
function CreateArchive( )
    var archfolder = "/sdcard/sjgapps/archive/"; 
    //Create project zip file.
    var zip = app.CreateZipUtil();
    var fldr = "/sdcard/DroidScript";
    var archname = (new Date).toISOString().slice(0,19 );
    archname = "ds"+archname.replace(/[-:]/gi,"");
    archname =  archname.replace(/T/gi,"_");
    var file = archfolder+archname+".zip";
    zip.Create( file );
    app.ShowProgress( "Archiving..." );
    AddFolder( zip, "DroidScript", fldr );
    return file;
//Recursively add folder contents to zip.
function AddFolder( zip, name, fldr )
    var list = app.ListFolder( fldr,"",0,"alphasort" );
    for( var i=0; i<list.length; i++ )
        var title = list[i];
        if( !app.IsFolder( fldr+"/"+title ) )
            zip.AddFile( name+"/"+title, fldr+"/"+title );
            AddFolder( zip, name+"/"+title, fldr+"/"+title );
function sendGmail(addr,pass,attach)
    //Create email object. 
    var email = app.CreateEmail( addr, pass ); 
    email.SetSMTP( "", 465 ); 
    email.SetOnStatus( email_OnStatus );
    //Send the email message. 
    app.ShowProgress( "Sending..." ); 
    email.Send( attach, "DroidScript backup for you.",  
       addr, addr, attach ); 
//Handle status messages. 
function email_OnStatus( status ) 
    app.Alert( status ); 


Personalise the code

You must change the email address and password in the first two lines

Version required

This code makes the assumption that you are using at least version 1.15 of DroidScript, as the path for your apps is hard coded but older versions used a different path

Possible Gmail Problem

The code used for emailing is pretty simplistic and you may get an authentication error if your gmail account is set to high security.

Filling your sdcard

There is no code included to delete the zip files.

Over time, /sdcard/sjgapps/archive will build up all the archives you create.

You should probably delete those files manually from time to time, probably after emailing them or placing them in your cloud storage.
