BTscoAudio

BTscoAudio is an android plugin for Locale, Tarker and Llama.
The purpouse is to route the audio to bluetooth sco channel, when an old car handsfree without a2dp is connected.

When the audio focus is requested by a selected app, the audio is routed to sco channel. When audio focus is abandoned, the sco channel is closed. The redirection may only ocurs, or works, with apps that request/abandon android audio focus. This is the way on how BTscoAudio detects that a sound is going to be played. For example, you may need to enable "Manage audio focus" Radardroid app option for working together with BTscoAudio.

Xposed framework is needed to delay the sound for the time needed to establish the sco connection and for detecting audio focus requests.
