Bluetooth Launch

數百萬款最新的 Android 應用程式、遊戲、音樂、電影、電視節目、書籍、雜誌等項目盡在其中，歡迎隨時隨地透過您的各種裝置取得。

Allows you to pick an activity to launch on when you use the Bluetooth button on most headsets.

This is no frills (some even call it ugly) but still works nicely. (Cut me some slack, I wrote it in 2 days, using standard UI elements from FroYo. That said, I see no reason to update it unless I'm really fixing something.)

Simply select the application to see a list of activities. Then pick the activity you want launched. For example:

Google Search

com.google.android.googlequicksearchbox.VoiceSearchActivity

That's it. Connect your headset, hit the button and you're good to go.

Notes:

Not all headsets work correctly. Some have odd behavior and do not follow the standard. I own only a couple of headsets and test to those.

Not all activities work correctly either. It is simply not possible for me to download and test every activity for every app. You are responsible for figuring out what works and what doesn't.
