Here is one of my recent posts on Facebook. It makes the outrageous claim that the web as you know it is going away...
Figure 1: Apps are killing the web
Here is the dialog on Facebook
|Me||The web as you know it is going away. If you are using a mobile device, 86% of the time you are in an app, not the web. And this is just the beginning.|
|Friend||I hope momentum swings the other way and apps die. The web is the only truly open platform. Why should I have to install the chipotle app just to order a burrito. I should be able to just go to their site and get the same rich experience.|
|Me||With that said, all the underlying web/networking infrastructure will remain.|
|Friend||It will, but I am still rooting for "web app" web and not just the "app" web|
|Me||Agreed - we can't be creating apps multiple times for each device. Html5 just can't leverage native device capabilities enough. But something has to give, too expensive to write an app multiple times.|
|Friend||I am reminded of this every time I have to nudge the browser window 10 times on a mobile device just to get to the level of detail I need. Native experience cannot be matched on the web, I think it's pretty clear now. But I do hope that the app delivery mechanism changes, i.e., the platform becomes smart enough to offer native experience when available. Perhaps we can even get away from the app model if we find a way to deliver rich user experience in some other way.|
So how will you build these native apps?
You need to balance the cost and effort to choose the right technologies.
This is the spectrum
There are 5 approaches you can use to create mobile apps.
(1) Responsive Web
Responsive web design (RWD) is a web design approach aimed at crafting sites to provide an optimal viewing experience?easy reading and navigation with a minimum of resizing, panning, and scrolling?across a wide range of devices (from mobile phones to desktop computer monitors).
Adjust CSS for mobile
But can't get into app store
(2) Hybrid Web
Allows you to get into app store
Examples are Cordova and PhoneGap
- PhoneGap is a mobile development framework produced by Nitobi, purchased by Adobe Systems in 2011.
- The resulting applications are hybrid, meaning that they are neither truly native (because all layout rendering is done via web views instead of the platform's native UI framework) nor purely web-based (because they are not just web apps, but are packaged as apps for distribution and have access to native device APIs).
- From version 1.9 onward it is even possible to freely mix native and hybrid code snippets.
Low effort, if you do web you can do PhoneGap or Cordova
Plugins can be written, but doing some native code, giving you more control, but requiring you to use more platform specific native features
(3) Mobile Web
The mobile web refers to access to the world wide web, i.e. the use of browser-based Internet services
Specific Pages targeting specific browsers on specific devices
High cost, more expensive than native (testing multiple browsers and multiple devices)
As mobile browsers gain direct access to the hardware of mobile devices (including accelerometers and GPS chips), and the speed and abilities of browser-based applications improve
Persistent storage and access to sophisticated user interface graphics functions may further reduce the need for the development of platform-specific native applications
The Mobile Web has also been called Web 3.0, drawing parallels to the changes users were experiencing as Web 2.0 websites proliferated
Traditionally, access to the Web has been via fixed-line services on laptops and desktop computers
However, the Web is becoming more accessible by portable and wireless devices
The prediction is that it is likely that web access from a mobile device will exceed desktop access within the next five years
The shift to mobile Web access has been accelerating with the rise since 2007 of larger multitouch smartphones, and of multitouch tablet computers since 2010
Both platforms provide better Internet access, screens, and mobile browsers- or application-based user Web experiences than previous generations of mobile devices have done
(4) Hybrid Native
More code re-use because you can use one language, like c# for all devices
With a C# shared codebase, developers can use Xamarin to write native iOS, Android, and Windows apps with native user interfaces and share code across multiple platforms
XAMARIN is a good example
- Write in one language but compiles to native language or binaries
- Write in C#
- Still need to write GUI in native environment
(5) Native Apps
Most control, best performance
But there is absolutely no code re-use. Can be prohibitively expensive.
- Android Studio, Eclipse using Java
- Consider Genymotion to help with development
- XCode using Objective-C and Swift
You will need to balance performance and control with effort to build. You also need to consider whether you can put the app into an App Store.
