Chrisubuntu Posted August 24, 2020 Share Posted August 24, 2020 Use case: Some Bluetooth devices (headphones/speakers) have dedicated Rewind/Fast Forward buttons (to not confuse with Next/Previous buttons). Additionnally, apps like this (https://play.google.com/store/apps/details?id=flar2.homebutton) allow to assign Volume buttons or assistant buttons (Samsung Bixby or LG assistant buttons) to rewind/fast forward. I always assumed that this only worked for Podcast/Audiobooks apps, but it works for many music players like Gonemad, Playerpro, Musicolet. So adding this would be useful when listening to long audio tracks in Poweramp. Quote Link to comment Share on other sites More sharing options...
andrewilley Posted August 24, 2020 Share Posted August 24, 2020 As long as those buttons generate long-press key events of KEYCODE_MEDIA_REWIND and KEYCODE_MEDIA_FAST_FORWARD, Poweramp should process them accordingly. Andre Quote Link to comment Share on other sites More sharing options...
Chrisubuntu Posted August 24, 2020 Author Share Posted August 24, 2020 Apparently, PA does receive the command (there's a beep sound) but nothing happens. It did rewind a couple of times, but not anymore. Quote Link to comment Share on other sites More sharing options...
andrewilley Posted August 24, 2020 Share Posted August 24, 2020 What does Settings > Headset/Bluetooth > Last Processed Commands show? (you can paste the results here if you like) Andre Quote Link to comment Share on other sites More sharing options...
maxmp Posted August 24, 2020 Share Posted August 24, 2020 Poweramp v3 does support media seek commands (no need to configure anything) and also the volume keys (search settings for volume keys) assignment. Thanks! Quote Link to comment Share on other sites More sharing options...

Chrisubuntu Posted August 24, 2020 Author Share Posted August 24, 2020 Seems like the first command is successful but subsequent ones fail. Then after a pause and resume, it works once then fail afterwards. Quote Link to comment Share on other sites More sharing options...
andrewilley Posted August 24, 2020 Share Posted August 24, 2020 The problem is that your button activity is generating a momentary click action - ACTION DOWN is immediately followed by ACTION_UP. FFwd and Rewind need the button to provide a press-and-hold action, and the fwd/rew activity will then continue until the button is released again.

maxmp Posted August 24, 2020 Share Posted August 24, 2020 Right, seems @Chrisubuntu device sends short presses. What is the device in question? I guess for these some pre-defined seek jump may be defined (e.g. 10 sec). Unfortunately all my test BT devices with seek buttons sends long clicks (seek starts and continues while button is pressed and ends when button is released), so I need to get the device which sends short commands for the testing.

Chrisubuntu Posted August 25, 2020 Author Share Posted August 25, 2020 @maxmp. I'm using a Samsung Galaxy Note 9 on Android 10 and I remapped the Bixby button (using the app I linked in the original post) to rewind. I also remapped the volume button (double press) to rewind with same results, so you could test using that if you don't have a phone with the Bixby button.

andrewilley Posted August 25, 2020 Share Posted August 25, 2020 As I said, Rewind is a press-and-hold feature, it is designed to continue to wind backwards for as long as the button is held (it also increases in speed the longer the button is held down by the way). Your app seems to be sending the effect of a single-press (i.e. click or tap) on a KEYCODE_MEDIA_REWIND button, which won't do anything useful as it would stop winding as soon as it starts. @maxmp I wonder if it might be worth interpreting single-click KEYCODE_MEDIA_REWIND and KEYCODE_MEDIA_FAST_FORWARD events as 10-second jumps?
