There is a third party plug-in that accomplishes this. The “Locale Plug-in Appli Detection” is available on the Android Market in all countries that support paid apps.

This is now supported with the combination of Locale 1.0 and the “Locale Headphones Plug-in”, both of which are available on the Android Market in countries that support paid apps.

Locale 1.0 supports plug-in conditions, so many more exciting features are coming soon :)

A plug-in to control media volume will be released in the near future :).

The free Day & Night Locale Plug-in is now available on the Android Market. This plug-in implements the original request of detecting sunrise/sunset based on time of year and latitude.

With Locale’s open plug-in architecture, the Locale part of this feature request is complete.

At this point dgAway would simply need to implement a plug-in setting for Locale. Please contact the author of dgAway, as the ball is now in his court.

A 3rd party developer has created a plug-in called “Locale Lockscreen Plug-in” that implements this feature request.

This plug-in can be found by choosing the “Get Plug-ins” menu item within Locale.
