Player with RUNTIME ERROR in Android 9

Bugs and Other Issues
1

Hello all.

I’ve got a “RUNTIME ERROR” when I’m using my app :
SImple FG Radio

It worked perfectly with my old phone Android 6 Snapdragon 820 6Go Ram Leeco Le Pro 3.
I’ve just bought a Xiaomi Redmi note 8 Pro global version with Android 9.
After a few minutes, the application stop playing. When I clic on STOP button, I’ve got a “RUNTIME ERROR” message.

I use the app on my Android 7 car unit without any problem.

I’ve try to remplace MIT player with the Taifun Player extention. The problem stills.

Any idea ?

PS : It will be very cool that the player cans control the audio buffer size when playing URL.

Probably a issue with Android 9, where the setting “Keep Wi-Fi on during sleep” has gone, see also here:

Sorry for my long silence, job…

You can find the ADB Log (only error) with this link :

I stopped the logged just after the application error. So you can find the problem at the end of the log.

If you want to log my app, you can download it here :

I precise the problem comes only with Android 9 an up.

I tried with a Xiaomi Note 8 Pro Global and a Samsung S10e.

The probem stays the same in 4G LTE in allowed background.

so this seems to be the error
