Android 2.0 finally adds APIs that would allow apps like Locale to implement a “Bluetooth Condition.” If this were implemented, it would only be available on Android 2.0 phones.

Update: There are some Android bugs that will prevent this from being implemented for the time being. Specifically, we’ve found that Bluetooth will periodically crap out until the phone is rebooted.

At long last Locale 3.0 introduces the Calendar condition to detect events on your Google Calendar, Exchange Calendar, or any other calendar supported by Android.

While Locale 3.0 is available for Android 2.2 or later, the Calendar condition requires Android 4.0 or later. To learn more about Locale 3.0, please see our release notes here http://blog.twofortyfouram.com/post/19303488607/locale-3-0

Scenes in HTC Sense is a private API, which means that third party apps like Locale cannot access it.

HTC has launched a new developer API for Sense UI devices at http://www.htcdev.com/

Unfortunately, these APIs are extremely limited and do not allow developers access to more advanced features such as Scenes.
