Add setting to rewind on double tap of headphones play/pause button

[kimsey0]

Sometimes, when I listen to audio books through my headphones, my listening is interrupted, and I have to rewind. I would like to be able to do this without taking out my phone. My headphones only have one button, a play/pause button. If I click it once, Voice pauses or resumes play. If I click it twice, Android interprets this as a command to skip to next, and Voice fast forwards.

I would like a setting where I can change this behavior so that Voice rewinds instead. I'll be happy to implement it and submit a pull request if @PaulWoitaschek is OK with having this setting.

I have the "Auto Rewind" setting set to 5 seconds (can go up to 20). If I want to go back a few seconds, I hit pause then play (and maybe a second time if I want to go back more). You do have to wait about a second between pause / play so the system doesn't interpret it as a double press.

@innesst: That's not a bad idea. I'll use that if this request isn't accepted. Thanks.

@PaulWoitaschek, what do you think about having such a setting?

This would need to be implemented 'reverse jump back and jump forward', since double press makes android give the app 'you got a signal: jump fwd'.

@PaulWoitaschek, what do you think about having a setting as described here?

If you implement this feature, please keep it as a settings to enable (or not) because on my bluetooth heaphone, the double press calls the last number I called which is a very (very) usefull feature. (My headphone has 3 buttons: 1=play/pause/start/stop/call last number, 2=decrease volume/rewind, 3= increase volume/fast forward)

I'm assuming events from a bluetooth headset look different from a wired headset?

I'd also appreciate this feature. I noticed that tapping the button press twice was skipping ahead by skip amount, when often this feature is used to rewind with audio books.

Although the above referenced issue is customizing the double button press behavior...

IMO, skipping forward is much less useful for an audio book app than skipping backwards.
