Did you read the very first post in this tread before posting?

Yes, I have translated it. Thank you very much for passing me a link and / or helping me a little more by specifically recommending where, prices, etc., you are very kind!

Thank you mate!!

@escitalofreniko Following 2 links point to Amazon Germany. You should be able to find such devices by searching for "DAB USB Android" in any marketplace, like eBay, Amazon, AliExpress, etc.
I usually do not give hints to such devices, because they are basically all the same, and the links to these items outdate within a month typically.

Within the apk it should be possible to change the color of the radiostation. I changed the color pressed OK but nothing happend. Perhaps this can be changed in a new version

Thanks for noticing this problem. Indeed, I must have broken this some time back. I will this is a next release (no date planned yet)

Is it possible to integrate clock somewhere in the app?
I am asking because when I use full screen I lose clock on upper right corner, and since it is only clock in car I am missing that information.
Thanks

Now it is getting weird... I can only reproduce this with my PX5 and PX6 devices, not on any other Android version and not on Android 10 Emulators. Don't know currently how to workaround this...

First of all: Thanks a lot for your work!

i have a problem on my PX5 / Android 10 / V 1.9.117

After external apps reducing the volume (eg notification of my radar app blitzer.de or my app for my carplay connection - navigation informations) the volume stays reduced - i have to restart the app to have the normal volume output again (the 2nd volume slider isnt changing anything)

 

[realzoulou]

I use Blitzer.de (Pro version) myself and never faced this issue that DAB-Z ducks but does not un-duck after the audio of the other app finished. Note: This is steered by Android itself when to un-duck.
If the DAB-Z Audio setting "Sound volume in background" does not change anything, then you have most likely set an App as the "Navigation application" in Android settings -> CAR settings -> Navigation. If there is an App defined, then some MTC system app takes over Audio Session handling and DAB-Z not even gets notified about any other app becoming the foreground audio app. Thus, the volume level in DAB-Z settings is not getting effective.
Try with no app set in Android settings -> CAR settings -> Navigation. Does this change anything?

Since this is asked quite often in direct emails, too, I will include this in a next release.

Thanks for your fast reply! I ve set the Navigation App and will try again without one

still the same - can I debug anything?

@realzoulou
if we are talking about ducking ...
I have following behaviour: DAB is set to reduce volume for ducking. But it unpauses itself after it was set to pause (manually) and navigation app said something.
Can someone confirm/contradict this? Is it intended behaviour?

 

[realzoulou]

Android's audio focus management is a "collaborative" one. This means it expects that Apps behave "nice" to Android (and therefore other Apps) and follow the Android documentation for "Manage audio focus": https://developer.android.com/guide/topics/media-apps/audio-focus

Expected behavior Ducking:
DAB-Z playing audio, other app starts a short-lasting audio output, DAB-Z ducks to the level configured in settings (default 50%), then other app stops audio, DAB-Z unducks.
Precondition: Some device specific system apps from MTC, FYT, etc. allow this behavior. Means: above applies only to a "near standard" Android device.
If DAB-Z previously got the pause command, it remains in paused.

Expected behavior Play/Pause:
DAB-Z playing audio, User pauses DAB-Z via a media control widget, launcher, from DAB-Z notification, etc. , then DAB-Z stops audio, other audio app can now output audio as long as it wants (ex. Youtube, Spotify, etc.). When User(!) brings DAB-Z to front and presses the big Play symbol shown "above" the logo, or is using media control widgets, launcher, etc. to command DAB-Z to play, then DAB-Z will continue to output the live DAB audio (no timeshift recording in the meantime). Other media player is expected to stop its audio output and decide by itself what to do now.
If during DAB-Z paused, another app does a short-lasting audio output (ex. Navi guidance), DAB-Z remains in pause (@IG_Vasilich : sic!).
If the above is not working as expected, it is likely an MTC, FYT, ... system app interfering with this standard Android behavior.

Expected behavior Mute:
DAB-Z playing, system wide Mute is triggered ex. via SWC, or volume control from status bar, etc., no audio output from any(!) app. Since Android 10, Android in parallel sends a pause command to the currently active audio source. Then User unmutes, (Android 10 sends play command) and DAB-Z is audible again.
If during Mute state, the User switches the audio source to any other app, then DAB-Z is not coming back of course when User unmutes.

That means that if i am on Android 10+ and have DAB paused, then after unmuting DAB will start to play? and you cannot change this behaviour because you (DAB-Z) will get proper intents to play and cannot recognize whether those come from my widget/launcher or were generated by android?

Anyway, pls set this information you posted above on first post of this topic, so the people can easily find it. It is kinda technical documentation, and in some cases is very valuable.

 

[realzoulou]

No, if DAB-Z was paused, it must not un-pause. Irrespective of what happens.
In other words: your behavior on Intel Sofia Android 6 is wrong and not expected

Some new stations don't have logos and when i tried to search for logo using the suggested "VW station logo download", am not getting anything usable off Google. Can some one please point me in the right direction? Am looking for logos from Germany Preferably the NRW region.

 

[IG_Vasilich]

@naira1
there are many logos built in DAB-Z. If there are some logos missing - have you tried to activate RadioDNS logos?
If there are still some logos missing after it - make a list of it (exact names) and post here (or export station list and post the generated ZIP file here).

Thanks! These are the ones with no logos.
