Native application or web application

Mon, 07/26/2010 - 03:01 | by gabor

Having an android device, makes sense mainly if you have Internet access all the time. So if we can suppose everyone access the net, it is obvious to think, that a mobile optimized site/web application can be used instead of a native application.

As I see the main advantage of a web based solution is platform independence, the same code can run on on any mobile phone .

I'd like to make an overview of the possibilities, and defects of a web based solution.

Possibilities:

It has been a while since is possible to create complex html and JavaScript based web applications for PC browsers. You can check out for example the YUI Library which helps building a rich user interface for such web applications.
The present smartphone browsers are capable of running these, they have enough brandwith, screen resolution, processor capacity!

If you want the web app to be present among other installed native applications you can compile a simple apk with a webview, to hardcodedly display the proper webpage. This way you can be present on the android market too.

Deflects:

The possibilities are promising, but the browser based solution has a lot of serious deflects, for example you can not:
- vibrate the phone
- use GPS
- use local database
- access accelometer
- access camera...

And there are even more device specific features, like notifications on android that can not be accessed from a browser.

Of course the application won't be usable in offline mode, and even online the browsers don't do such a delicate caching like you can implement in a native app, so it can affect speed.

Solutions:

HTML5 is one of the promising coming solution for most general problems. For example the HTML5 specification contains:
- database handling
- GPS using
- delicate cache control
- 2d and 3d graphic acceleration...

Unfortunately we have to wait a little more for this, the current browsers have not enough HTML5 support, to start to relay on them right now.

Check out your browsers HTML5 compatibility level here.

The other thing, helping the developers, are projects like PhoneGap. This project offers access from JavaScript to device specific possibilities, supporting many platforms.

Summary:

Even now, we often can see applications which somewhere solves some part of the functionality using a webview, because thats the best way. In the future, as web will continue to develop, and will be used more in smartphone development too.

They also demoed Chrome to Phone, which is a way to push intents to your phone. But they haven't quite ported that into the Android browser yet. En Güzel En Komik Oyunlar Burada Sizleri bekliyor.

The user interface of iOS is based on the concept of direct manipulation, using multi-touch gestures. mcse 2003 Interface control elements consist of sliders, switches, and buttons. The response to user input is immediate and provides a fluid interface. Interaction with the OS includes gestures such as swiping, tapping, pinching, and reverse pinching. Internal accelerometers are used by some cwna applications to respond to shaking the device (one common result is the undo command) or rotating it in three dimensions (one common result is switching from portrait to landscape mode).Many other DLLs exist within Windows as components itil v3 certification of specific programs or services that are provided with the operating system, and third-party programs or services added to the system can come with DLLs of their own as well. These are not considered library files, as they are not (in general) callable by other ccie training applications, and are not discussed here.

Current State

GodsMoon | Thu, 07/29/2010 - 11:02.

Good article.
The current state of webkit (used in Android, iPhone and soon Blackberry) has some HTML5 support.
GPS currently works.
Google demoed the accelerometer at GoogleIO and said it was coming soon.
The same for the camera.

They also demoed Chrome to Phone, which is a way to push intents to your phone. But they haven't quite ported that into the Android browser yet.

Google is certainly going in the web app direction, but we just aren't at that point yet.

I hear there is some internal debate at Google about this. Apparently, this is why Google hasn't released a Google Voice app for desktops. They want to see it as a web app instead of a native one.

NextStop (recently acquired by Facebook) is one of the few companies I've seen do a really good web app for phones. They explain it here: http://www.youtube.com/watch?v=Jks-idxVrCs

Hero better than Firefox?

On the test site mentioned in the article, Firefox 3.6 scores 139, while the browser on a 2.0 Hero scores 151! Now that's surprising...
