Backwards Compatibility

[benreed]

Hi all,

I can't seem to find a definitive answer to this so thought I would open it up to the community here. Does anyone know if a WRT widget written and tested on a device running WRT 1.1 will work on newer devices running 7.3?

Thanks!

Ben

Hi Ben.

Giving definitive answer is a difficult task. Most likely it will work, but to make it work seamlessly one should take new features into account. If you look at the list, most of changes are due to supporting Homescreen widgets. (Timers, online/offline API etc..)

So what have changed:
- Online/offline functionality should be implemented to offer best possible UX for Browser 7.3 equipped devices. (Supported since Browser 7.1 / WRT 7.1)

- Timers. If your widget relies on a timer running constantly on the background, it might not work properly.

Then we have newer issues specific to Browser 7.3 / Symbian Anna

- http://www.developer.nokia.com/Commu...in_Browser_7.3
- Bunch of issues related to Platform Services If you widget does not use Platform Services, you should be on a safe side.

Anyhow, the only way to make sure it works (or breaks), is to test it on a real device.
If you don't have access to Symbian Anna devices, please test it on a remote device access service.
