eBay aims for $1.5 billion in mobile sales in 2010 internet retailer, Q1 2010 mobile download revenue exceeded $29.5 billion by 2013 Gartner, Q2 2010 07/Q2 07/Q4 08/Q2 08/Q4 09/Q2 09/Q4 10/Q2 10/Q4

I want an iPhone App !

diversity of platforms

94 App Stores

two categories

How can we address this diversity?

You can write amazing web apps that look exactly and behave exactly like apps on the iPhone Steve Jobs, WWDC 2007

WEB APPS

apple.com/webapps openappmkt.com

what’s that native thing?

Unreal Tech Demo demo

the User’s perspective on Apps

Experience

pre-installed downloaded online native website W3C widget hybrid interpreted generated

web apps

HTML5 cache manifest, local storage, forms, geo location CSS3 animation, transitions, 3D transformation Resolution css media queries, reference, categories, ﬂoat layout URLs mails, telephone, sms, maps, youtube, etc.

Web Frameworks iWebKit, iUI, jQTouch Sencha Touch 2010 Q4: JQuery mobile framework

Sencha Touch MIT License GPL Dual License declarative + JQuery programmatically focus on iPhone aims at cross platform simple complex See also iWebKit, iUI, jQTouch, JQuery Mobile (2010 Q3)

development easy effort known technology + processes monetization bad for user experience experience fancy UI possible, but platform speciﬁc hardware very limited ofﬂine generally possible

hybrid apps

Request Interception demo

MIT License See also QuickConnect, Big5 (discontinued)

development as with web effort known technology + processes monetization app stores experience as with web hardware mostly accessible ofﬂine as with web

interpreted apps

– HTML & CSS =

Apache 2 License JS programmatically native controls iPhone, iPad, Android BlackBerry (soon)

MonoTouch Rhodes starts at 399 USD MIT License .net runtime ruby C/S on the device iOS only iPhone, Windows Mobile 6, BlackBerry, Symbian and Android

Screen Flow Interpreters The aim of XXX is to screen the programmer completely out from the mobile platform itself, and transfer the entire application logic to central application server level.

development heavy API, but only once effort barely any tooling monetization app stores experience native hardware mostly accessible ofﬂine native

generated apps

XMLVM — A CrossCompiler

Java (input) public class HelloWorld { static public void main(String[] args) { System.out.println("Hello World"); } }

XML (model) <vm:xmlvm xmlns:vm="http://xmlvm.org" xmlns:jvm="http://xmlvm.org/jvm"> <vm:class name="HelloWorld" extends="java.lang.Object"> <vm:method name="main" isPublic="true" isStatic="true" stack="2" locals="1"> <vm:signature> <vm:return type="void" /> <vm:parameter type="java.lang.String[]" /> </vm:signature> <vm:code> <jvm:var name="args" id="0" type="java.lang.String[]" /> <jvm:getstatic class-type="java.lang.System" type="java.io.PrintStream" field="out" /> <jvm:ldc type="java.lang.String" value="Hello World" /> <jvm:invokevirtual class-type="java.io.PrintStream" method="println"> <vm:signature> <vm:return type="void" /> <vm:parameter type="java.lang.String" /> </vm:signature> </jvm:invokevirtual> <jvm:return /> </vm:code> </vm:method> </vm:class> </vm:xmlvm>

XSLT (generator) <xsl:template match="jvm:irem"> <xsl:text> _op2.i = _stack[--_sp].i; // Pop operand 1 _op1.i = _stack[--_sp].i; // Pop operand 2 _stack[_sp++].i = _op1.i % _op2.i; // Push remainder </xsl:text> </xsl:template> typedef union { id o; int i; float f; double d; } XMLVMElem;

Output + (void) main___java_lang_String_ARRAYTYPE :(NSMutableArray*)n1 { XMLVMElem _stack[2]; XMLVMElem _locals[1]; int _sp = 0; XMLVMElem _op1, _op2, _op3; int _i; for (_i = 0; _i <1; _i++) _locals[_i].o = nil; NSAutoreleasePool* _pool = [[NSAutoreleasePool alloc] init]; _locals[0].o = n1; _op1.o = [java_lang_System _GET_STATIC_java_lang_System_out]; _stack[_sp++].o = _op1.o; _stack[_sp++].o = @"Hello World"; _sp -= 2; [((java_io_PrintStream*) _stack[_sp].o) println___java_lang_String:_stack[_sp + 1].o]; [_pool release]; return; }
