Apps Divergence between respective Android devices

[Haderach]

Hi,

While now I'm thinking of development of application on Android device, is there any divergence between each Android device that are distributed in many countries ?

In other words, do I need to conduct a test of my application by means of lots of Android devices in the world in order to check of my application's behaviour ?

It would be much appreciated if you could give any advice for me.

Kind regards,
Haderach

No, the ui elements are handled with xml which can be customized for each locale setting. As far asactual coding goes, if it works for one locale it will work for others. thehardware itself is the same world-wide. The default locale setting (changeable by anyone)is the only thing that differs (and sometimes the OS version depending on carrier).

You do have to take different android versions in account. While making your app you can set a target version. That means that probably any phone running that version or above can use your app. But when the phone has a lower version it probably can't run your app because it may contain functionality not available for the lower android version (like multitouch in android 2.0>).

And you should check on multiple phones, as HTC run sense on top of Android, it depends what your app does. Also some phone's run different resolutions or default to landscape and not portrait, this can all be accounted for in your resources:
