App ignores commands from headset #111

keddad · 2020-01-11T11:53:50Z

Hi! I'm running version 4.0.1 from F - Droid on Android 9. Player works very well, and I love it, but I faced an issue: app ignores commands from headphones like pause or previous/next track. But it is definitely not headphones issue: they work well with other players. What logs can I provide to help fixing this bug? The only thing I could find by myself were logs in LogCat about headphones button press, but they seem normal, so I guess these are not really helpful:

01-11 14:49:58.111 D/NewAvrcpNativeInterface(2280): sendMediaKeyEvent: keyEvent=76 pushed=true

The text was updated successfully, but these errors were encountered:

Hi, I'm gonna send you a test apk. :)

keddad · 2020-01-11T13:32:45Z

That would be great! Here they are:
70 - Pause
75 - Next Track
76 - Previous Track

enricocid · 2020-01-11T13:52:57Z

Do you resume playback too with pause button?

keddad · 2020-01-11T13:53:32Z

Yes

enricocid · 2020-01-11T14:03:13Z

I registered those key events here:

keddad · 2020-01-11T14:06:01Z

That's strange. I can see MediaKeyEvents in LogCat viewer, but the app still ignores them

enricocid · 2020-01-11T14:17:06Z

in the logcat you should find a output called "action". Could you post it here?

keddad · 2020-01-11T14:44:40Z

I might be doing something wrong, but if I do

keddad@keddad-pc:~$ adb logcat -s "action"

I can see basically nothing:

keddad@keddad-pc:~$ adb logcat -s "action"
--------- beginning of system
--------- beginning of crash
--------- beginning of main

Logcat itself is file, adb logcat still works. If I press any buttons on the headphones, there are still nothing in the output of -s "action". If I just grep "Action", there are nothing useful too:

keddad@keddad-pc:~$ adb logcat | grep Action
01-11 17:27:56.740   883  1083 I ThermalEngine: j=0 i=0 TM Id SKIN-BATTERY-MONITOR Sensor xo_therm: Action battery value 0
01-11 17:28:02.751   883  1083 I ThermalEngine: j=0 i=0 TM Id SKIN-BATTERY-MONITOR Sensor xo_therm: Action battery value 0
01-11 17:29:15.845   883  1083 I ThermalEngine: j=0 i=0 TM Id SKIN-BATTERY-MONITOR Sensor xo_therm: Action battery value 0
01-11 17:30:51.956   883  1083 I ThermalEngine: j=0 i=0 TM Id SKIN-BATTERY-MONITOR Sensor xo_therm: Action battery value 0

If I grep "action" there are much more, but it is still useless. The only thing related to the buttons in the logs are still KeyEvents:

01-11 17:42:21.418 15865 15885 D NewAvrcpTargetJni: sendMediaKeyEvent
01-11 17:42:21.418 15865 15885 D NewAvrcpNativeInterface: sendMediaKeyEvent: keyEvent=70 pushed=false
01-11 17:42:21.418 15865 15885 D NewAvrcpTargetService: getMediaKeyEvent: event=70 pushed=false
01-11 17:42:21.418 15865 15885 D NewAvrcpMediaPlayerList: sendMediaKeyEvent: key=70 pushed=false

enricocid · 2020-01-11T20:57:03Z

Could you please try?

keddad · 2020-01-11T20:59:55Z

Now I can go to next/previous track and pause the track, but I can't unpause it.

enricocid · 2020-01-11T21:07:08Z

Can you describe the buttons?

Do you have one button to manage play pause?

keddad · 2020-01-11T21:08:45Z

Yes

enricocid · 2020-01-11T21:19:43Z

keddad · 2020-01-12T05:53:58Z

Amazing, it is working! Thanks!

enricocid · 2020-01-12T07:51:01Z

Great, thanks!!

enricocid · 2020-01-19T16:27:05Z

Hi, sorry for the disturb but I need you to test this apk

https://drive.google.com/open?id=1fsvkv7dkm28lRCdWqq8q3dpilqaFZ7VJ

I'm trying to optimize the code for media buttons.
Could please let me know:

if the headsets buttons are still working properly
what happens when you stop playback/kill the service (stop the playback from the notification).

thanks

keddad · 2020-01-19T16:29:03Z

I`m afraid that this headset died couple of days ago :D Sorry for that

enricocid · 2020-01-19T16:36:01Z

noooooo, i'm sorry... my nexus 5 died yesterday because of swollen battery and I now have to use emulator...

No problem, there's an app in the sdk to help devs to test hardware controls.

https://drive.google.com/open?id=1kp0yVFDwwLeo5oF7eawTRdQqeeY6mciM

Could you please install this apk, then click on the 3 dots -> hardware controls and let me know if the buttons are working also for you (just to be sure) with the apk above? thanks

keddad · 2020-01-19T16:40:48Z

I've tested it with this app, and hardware buttons work just fine. When the app is closed from the notification, it closes just fine, nothing special happens. Jan 19, 2020 19:36:03 enricocid <[email protected]>:

enricocid · 2020-01-19T16:43:25Z

Thanks.
With the app closed/killed service, what happens if you use hardware controls (hopefully nothing)?

keddad · 2020-01-19T16:44:49Z

Well, nothing. It is probably intended behavior, right? Jan 19, 2020 19:43:27 enricocid <[email protected]>:

Yes, I want the app to respond to buttons only when opened or playback is active. The default behaviour of android os is to try to launch playback from the latest app connected to mediabrowserservice... since i've not implemented the full client the app crashes on certain devices so I had to ensure to disable this behaviour to avoid issues :) thanks :)
