Since both companies Xtrons and Joying don't care at all about their DAB+ app extremely stuttering when running in the background, I started to patch their versions of the DAB+ app.
I gave the detailed instructions how to change the code of the DAB+ App to Joying. They appreciated my effort and promised to give this info to the original developers of the App. They did not want (or cannot) give me the contacts of the original developer/company responsible for the DAB+ App (com.ex.dabplayer.pad).
However, also their recent new versions of the DAB+ App do not bring with them the solution for the stuttering issue when in background. So I will continue to patch it...
The app is now available in Google Play named "DAB-Z" with package name "com.zoulou.dab".
It can be installed in parallel to any original preinstalled DAB+ Player.
Get DAB-Z on Google Play
The last version of the modded DAB+ App ZOU-DAB+180804 is available in Post #1265.
This version is no longer maintained.
#1 On Android 7.x.x with an Allwinner T3 Quadcore CPU, DAB-Z cannot be installed from Google Play store. It is shown as incompatible. Why and can I install it somehow else?
#2 Where can I find old versions of DAB-Z?
#3 Where can I find old versions of the mods for DAB+ (com.ex.dabplayer.pad) ?
#4 Audio stutters, especially when DAB-Z is in background and I use other apps. But the antenna signal is perfect. What can I do?
a) Some users report that it helped to reduce or eliminate the audio stuttering by adding a (unpowered) USB hub in between head unit and USB DAB adapter.
b) Some users report that switching to OMRI (see Settings/General) helped to get rid of audio stuttering
