Please try the public beta. See post #1 how to subscribe to the beta channel.

OS version would still be interesting for me to know.
[Android Head-Units] IG_Vasilich:
@realzoulou

i cannot make raw recordings of those 2 stations with missing last char in name:

"MDR Thüringen Nord-W" does not reach the place where i live (Mainz),

and "RadioRüsselsheim" will start to broadcast again in October (it shares frequency with other channel, and goes online every 3 months). So earliest recording i can make, will happen in October.

Any chance to get the support for Dasaita DAB Box?

https://de.aliexpress.com/item/32810941079.html

I use the Dasaita PX6 HE with the DAB Box.
[Android Head-Units] realzoulou:
No
[Android Head-Units] Don Kihoty:
So im ****-out-of-luck, and cant use this ROM(?):

https://xdaforums.com/t/vivid-rom-for-px5-px6-with-android-10.4251487/
[Android Head-Units] realzoulou:
The ROM has nothing to do with DAB-Z
[Android Head-Units] Don Kihoty:
I tough that this ROM had the DAB-Z integrated. Maybe im wrong about that.
[Android Head-Units] Shakin_Stevens:
Hi all,

I'm sorry if this has been asked before, I did do a search but couldn't see anything.

I've recently come back to DAB-Z (my crappy stick on DAB aerial stopped working and it took me ages to fit a permanent aerial!) Anyway, the app is even better than when I last used it, thank you to realzoulou for all your hard work. (y)

My only issue is that when I start the app it turns my wifi connection off on my head unit! If I go in to settings on the head unit I can see that the slider switch for wifi has been changed to off, when I slide it to on it changes itself back to off instantly. I have tried 3 different wifi networks and it's the same on all of them. When I exit the app the slider switch is still set to off but will allow me to change the slider to on and it will remain on until I open the app again.

I have a PX5 head unit with Hal9k Mod 4.2.1 installed. I will ask on that thread also, I was just wondering if anyone had come across this issue on their head unit as it's the first time I've experienced it?

Many thanks
[Android Head-Units] realzoulou:
This was never reported to me so far, not in this thread and not via direct email.

I used PX5 + Hal9k Mod 4.2.1 myself for months and I always had the PX5 connected via WiFi to my phone hotspot, of course also DAB-Z running in parallel.
[Android Head-Units] okij:
Same here, never had wifi problems with this combination. I'm now using PX6 + Hal9k Mod 4.2.1, also no problems.
[Android Head-Units] eddom1971:
hi guys .

anyone 1 else having issues with some stations having no audio in the latest version .

Namely in demand radio in the uk. no sound at all from this station when in OMRI mode .

station info says signal quality is best but audio codec shows as blank. . turned of OMRI mode and rescaned stations and it now works so must be a problem with omri .

using px5 android 10 hal9k rom 5.0.1

cheers
[Android Head-Units] okij:
The best way you can help @realzoulou to fix this issue is to take a raw recording (please see op for instructions) and provide it to him.
[Android Head-Units] IG_Vasilich:
@realzoulou

the raw file and backup of station list, as promised.

The channel name is still "RadioRüsselshei" with missing last "m" - that was not the case half a year ago
[Android Head-Units] brightsidebob:
I use DAB-Z for a long time now and it's probably the best DAB+ app out there for chinese HUs out there, i think.

Just a question: will there be a homescreen widget eventually? i use Malaysk and have widgets for music, bluetooth music and FM/AM radio for convenience. would be nice to have a little start/stop/next/previous widget for DAB-Z as well.
[Android Head-Units] lulukaka:
Hi, I live in Milan. How can I find dab radio station from Switzerland, Germany and France? Dab-z only finds radio stations from dab Italy. Thanks
[Android Head-Units] okij:
Well, by traveling to Switzerland, Germany and France, I suppose. 😉

DAB is broadcast locally in each country and the range is limited.
[Android Head-Units] okij:
Have a look at Ubiquity Music Widget on Play Store. It supports many different players, IIRC also DAB-Z.
[Android Head-Units] BigManni:
@realzoulou. Thanks for the cool app. since version 105 everything runs perfect and very stable on my MTCE-PX5.

I have a suggestion for a feature:

The dimming of the image coming from the radio station goes only manually and is not saved.

Is sometimes too bright at night when it is not dimmed.

Cool it would be if it were possible to make this function automatically via the day / night mode from the Headunit , or the program remembers the last state.

thx
[Android Head-Units] IG_Vasilich:
Is this not the thing that HU itself should do (i mean brightness reduction at night)? I set my HU to reduce brightness when headlights are on, so the car uses its built-in light sensor to switch headlights on, and in that case HU reduces screen brightness. The level of screen brightness dimming is adjustable, so everything is going to be darker - not only pictures in DAB-Z, but also album covers in any music player, and any other bright UI elements...
[Android Head-Units] NogenLunde:
You need an Internet radio app to listen to radio stations world wide. Lots of apps for this on Google Play.
[Android Head-Units] BigManni:
This also works with the HU.

But it still quite bright when for example a white logo or cover appears, even if you HU switches the smallest brightness.

Through the black background it could be very bright.

The function to dim is already built but does not remember it at startup
[Android Head-Units] TorstenH:
Usually the head unit dims the display if there is a +12V signal on the ILL/ILLU wire. So there is nothing to remember.
[Android Head-Units] marcothebasi:
hi .. with the dab-z app with the omri mode active I can no longer tune them mux 8c (swissmediacast), while with the omri mode disabled or with the use of other apps I feel it without problems .. is it possible to solve? ? Thank you
[Android Head-Units] realzoulou:
Yes, an update which fixes 8C in Switzerland is already in progress...
[Android Head-Units] marcothebasi:
thanks .. don't know how long it will take for the update?
[Android Head-Units] 5ams82:
i hope the update comes soon, i miss my beloved radio stations.

But really good work so far with the app! Thank you

is there a chance to see a new design like on some oem radios in the future?
[Android Head-Units] realzoulou:
The update should appear in the beta channel in less than a week. I will write a release post here as usual
[Android Head-Units] realzoulou:
DAB-Z release 1.9.114

Change log:

compared to 1.9.110

Added a 4th swipeable view showing News, Traffic, Weather and more DL+ infos, if supported by station

DLS text shows DL+ 'Programme Now' info, if supported by station

Fix: Some stations are not found during station scan (e.g. 8C in Switzerland)

Fix: Some station names miss the last character (e.g. Rüsselsheim)

Due to Android 11 Scoped Storage requirement, changed the path to DAB folder to <sdcard>/Documents/DAB/ (was <sdcard>/DAB/ before)

All data is migrated automatically. Users with logo files in DAB/logos/ will see a sync dialog at first start.

@IG_Vasilich Please delete "Rüsselshei" manually and then perform a station scan.

@ All: I propose you all perform a station scan to pick up the new stations that nearly all will be able to receive now.
[Android Head-Units] marcothebasi:
is this version already on the play store?
[Android Head-Units] realzoulou:
For now it is only available in the beta channel
[Android Head-Units] 5ams82:
Great work, thank you!

Is there a way to get lower Logo brightness, i have set it to 0% and it's still very bright when i drive my car at night
[Android Head-Units] IG_Vasilich:
@realzoulou

i have scanned all the stations in "update" mode, then have checked Rüsselsheim - it has updated its name to full (with last "m"). So - no need to delete it first.

What reasons were there for not saving/taking last letter for some station names? still smth with encoding?
[Android Head-Units] realzoulou:
@IG_Vasilich Ok, good. I was not sure if a re-scan would kick the wrong Rüsselshei station out, or not.

Well, root cause was a small mistake when dealing with EBU character set and checking against the max allowed length of 16 for service labels.
[Android Head-Units] marcothebasi:
ok thanks .. it will be a long time until it goes to the play store?
[Android Head-Units] realzoulou:
I usually give a week at least in beta channel and if no critical issues are reported, I post it to the production channel
[Android Head-Units] comicius:
I like DAB-Z. It is working as I expect, and instead of other users I don't have crashes.

But I have two wishes:

1.) I use DAB-Z in my car radio, and i often change DAB-Regions. Then I have to do the scan again which needs a lot of time, and when I go back in my main region, the same: Do the scan which needs a lot of time.

Is it possible to save the regions lists and load it then?

2.) I don't know if that's possible, but in fact that the DAB+ volume isn't as high as i.e. FM or Navigation, it would nice to have a volume "boost"
[Android Head-Units] IG_Vasilich:
@comicius

1. You can use station list export and import - it will save/restore all your stations and favorites to one file with name of your choice, so you can load exported stations later when you come to another area. You can have several sets of stations - for every area you visit.

Tip: If there are same stations in both regions you visit, that you like to hear, but those have different frequencies, then "service following" feature is very handy (if you live in Germany - this is especially comfortable for stations in both Bundesmuxes ("DR Deutschland" and "Antenne DE")).

2. Increasing volume level for digital signal will mostly lead to (digital) signal overloads = decreasing sound quality.

Many headunits (at least chinese :) ) have separate settings for different audio sources. E.G. my HU has settings for music (used by any android music player incl. DAB-Z), FM Radio, Navi, TV, AUX. So i set lower volume level for FM radio in HU, and lowered output volume in my music player to get same volume everywhere.
[Android Head-Units] realzoulou:

Hi guys,

i have an pumpkin px5 car Radio and if i want use the dab-z app, the App is hanging on the screen "Synchronisation" and it is blinking very fast. What can i Do? Thx a lot

Sry 4 my broken Englisch xD
[Android Head-Units] realzoulou:
Delete the folder /sdcard/DAB/

When using a File Manager App, sdcard ist usually called "internal memory" or similar
[Android Head-Units] der_dicke123:
Thx, i dont have this folder. Its a fresh Installation.
[Android Head-Units] realzoulou:
If you previously had DAB-Z installed, then your device has such a folder
[Android Head-Units] der_dicke123:
I will believe it, but i cant find this folder. Is the reason, that i have no sdcard? I use only the internal memory
[Android Head-Units] NFJ74:
Ich habe das gleiche Problem. Neuinstallation, App startet bleibt flackernd bei "Synchronisation" hängen.

Den Ordner /sdcard/DAB/ gibt es nicht.

Wenn du ne Lösung findest, sag bitte Bescheid :)
[Android Head-Units] der_dicke123:
Was mir einfällt, möglicherweise ist bei mir die DAB+ Box defekt und wird nicht erkannt. Ich soll bis Freitag ein Ersatz bekommen. Vllt hilfts ja
[Android Head-Units] realzoulou:
DAB-Z release 1.9.115

Change log:

compared to 1.9.114

Hotfix: Start of app is blocked by a continuous Synchronisation dialog

The issue was introduced in 1.9.114 with "Android 11 Scoped Storage support and automatic data migration".

The fix is to not migrate any data in the shared folder /sdcard/DAB to the new folder /sdcard/Documents/DAB.

User updating from 1.9.110 directly to this 1.9.115 will find imported logos, exported station lists and audio recordings to be "gone" (although the files are still in the old /sdcard/DAB folder, but 1.9.115 does not known about this anymore)

The release is already available in the Play Store public channel at the time of this writing.
[Android Head-Units] Boby_s:
I have the same problem - there is a continuous loop in sync during installation. My USB model is DTR-100 and my car radio is TS10 Topway.
[Android Head-Units] IG_Vasilich:
@der_dicke123 please use English here

@Boby_s with new .115 version?
[Android Head-Units] pogit:
When not in full screen mode, showing favourites only the station save in position 01 is not shown or partially shown is anyone else experiencing this? I have’t noticed it previously so I think it’s relatively new issue.
[Android Head-Units] IG_Vasilich:
i can reproduce this only in case of switching off fullscreen mode in settings and coming back to GUI. Once restarted DAB-Z and everything is good again.
[Android Head-Units] 5ams82:
since last update everything works smooth for me.

I hope for a Design Update, VW cars having nice Radio control
[Android Head-Units] realzoulou:
DAB-Z release 1.9.116 BETA

Change log:

compared to 1.9.115

* New: Splash screen at app start

* Fix: On some devices steering wheel controls not working

* Fix: On some Android 11 devices start of app is blocked by a continous loop of storage-related dialogs

* Fix: After import of station list, app restart was needed

Spoiler content hidden.
[Android Head-Units] okij:
Thanks for the new beta version. :)

There are some issues with the new splash screen:

When switching between players, now DAB-Z doesn't stay in background anymore (once it has first been started), but shortly flashes to foreground, please see attached video #1 (I had to zip it to be able to attach it). This sometimes also leads to short audio glitches, as can be heard at 0:00:19 (I assume because the CPU is busy switching screens forth an back, even though I have a PX6 CPU).

When pausing DAB-Z and then resuming DAB-Z again, now the DAB-Z screen is shortly shown and doesn't stay in background, please see attached video #2.

I'm using FCC Launcher with DAB-Z, NavRadio+ and GoneMad Music Player assigned to the Player widget and all players used to stay in background once they were first started, which also worked well with DAB-Z until the last release version 1.9.115.

Please fix these issues in the next beta or release version, e.g. by adding an option to either enable the new splash screen, enable the old small popup or totally disable any splashes or popups. I would prefer the third option. Thank you. :)

Hehe. Also I'm not affiliated with "WDR", which is shown in my videos, it's just my "Haus und Hof Sender". ;)
[Android Head-Units] NogenLunde:
Interesting, because I have the same, but worse audio glitches, or stuttering, always when switching stations, in all versions after 1.7.75. And my unit has a Snapdragon 625 CPU. I get this glitch/stuttering also sometimes when switching to the units Options menu, and when resuming real time after using timeshift. @realzoulou has looked into it, the CPU load seems to be just fine.
[Android Head-Units] realzoulou:
@okij I installed FCC beta 3.442 and looked at what you showed in your videos. It has nothing to do with the Splash screen actually. I went through your videos frame-by-frame and what you see is not the splash screen but the Player activity briefly coming to front. Not 100% sure why 1.9.116 suddenly behaves differently in conjunction with FCC, but I found a way to avoid this. I release another beta with the fix soon.
[Android Head-Units] realzoulou:
@NogenLunde Could you execute this command in order to see what CPU governor is configured for your device?

cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

On my PX5 test device is shows "interactive" for all 8 CPUs, which is a good choice IMHO.
[Android Head-Units] NogenLunde:
@realzoulou

I get "schedutil" on all 8 CPUs. I can change this to "interactive" if you think that can solve this. But "schedutil" should be better, according to google search?

Description:

schedutil is a new EAS governor found in recent versions of the Linux Kernel (4.7+) that aims to integrate better with the Linux Kernel scheduler. It uses the kernel's scheduler to receive CPU utilisation information and make decisions from this input. As a direct result, schedutil can respond to CPU load faster and more accurate than normal governors such as Interactive that rely on timers.
[Android Head-Units] NogenLunde:
Could we have an option to change this? Almost always when I want to record something, I wish I could rewind a few seconds to the start of the song or conversation.

Wouldn't this be a killer feature?
[Android Head-Units] realzoulou:
When you sent my the systrace back in April 2021, your Android system reported to be "PKQ1.190202.001". This would translate to Android 9. Android 9 comes typically with one of 4.4.x, 4.9.x or 4.14.x kernels. I was not able to find out your kernel version. Anyway... if I was you I would try out "interactive" or even "performance" CPU governor setting. Just to see if it makes any difference, or not...
[Android Head-Units] NogenLunde:
"Performance" did not make any difference, and "interactive" wouldn't activate.

When using Timeshift, and rewind after switching station, the stuttering that was on the live audio, is not there on the Timeshift recording. A few seconds of stuttering again when resuming live audio.
[Android Head-Units] 5ams82:
since the last public release sometimes after a fresh start of Android there are no Stations found, after relaunching dab-z for 2-3 times they come back
[Android Head-Units] realzoulou:
DAB-Z release 1.9.117

Change log:

compared to 1.9.116 (will not become public)

* New: Android 6 and higher: Show signal level in Notification icon when DAB-Z in background; can be disabled in Settings->Layout

* Fix: FCC's play, pause or player-switch causes DAB activity to be briefly visible although remain_background = true

DAB-Z in background with a current signal level of 2 (of 5) bars:
[Android Head-Units] okij:
Thanks a lot! I can confirm that DAB-Z now stays in backgrund when it's controlled by FCC Launcher.

The signal display in the notification icon is a great idea and a welcome addition. :)

Hello. I have ISUDAR PX6 8GB ROM 64RAM Andriod 10 MCU MTCE_GS_V3.73_3. USB DAB+ tuner also is from ISUDAR. Not function automatic start apk after "soft" start of device. After hard start (boot) device this function working, but only once. DAB-Z version is 1.9.117, I am beta tester. Launcher is CarWebGuru. But automatic start od DAB-Z not working also with original launcher fro ISUDAR. Can you help me?
[Android Head-Units] IG_Vasilich:
@Miklisek

either try to use other launcher with autostart function (e.g. Car Launcher pro)or use other automation tools (e.g. Tasker, Macrodroid, Automate)
[Android Head-Units] Miklisek:
Automation tools are not functional. Launchers (original and also others) kill they same as DAB-Z. Car launcher pro is not free, I am afraid, that situation will be same. Only Agama launcher has Autostart function of APK. But I preffer CarWebGuru launcher. Why autostart of APK was functional in 7.1.2., in Android 10 not? Any other idea?
[Android Head-Units] IG_Vasilich:
your previous HU/Android started DAB-Z after recognizing of DAB adapter in USB.

Seek for similar version in your new HU.
[Android Head-Units] realzoulou:
The root cause is likely in the ISUDAR provided Android 10 ROM. Because you have an MTCE GS unit, you could try a different ROM. I vote for @Hal9k_ 's fantastic Android 10 ROM in https://xdaforums.com/t/rom-px5-px6...ctx-head-units-with-android-10-9-8-6.4314163/

Yes, it is not for free and there is no guarantee that it will fix your DAB-Z autostart issue, but it is worth every Ruble/Cent. And it allows you to define autostart apps and an option to reset USB hardware after resume from deep sleep, and much more, which fills a whole thread...
[Android Head-Units] Miklisek:
@realzoulou: it is possible, but not good idea for me, I installed different original ROM (from ISUDAR support) to my car device, it was before 2 years, and radio was dead, it was not possible rescure. Yesterday I found a quick start at list of APK, now functionality automatic start of USB DAB tuner is good.

[Android Head-Units] mawi29:
Hi there. I want to report a bug. I am not sure if this is in the DAB-Z app or in the Android head unit, but this is it: the app or head unit does not remember if the sound is muted. This manifests in 2 cases. First when I mute, then go in reverse in my car, this activates the rear camera, then go in forward fear again, the sound starts playing. Another one is when I get to work and about to drive in the parking garage, I press mute because in the garage there is hardly any DAB+ signal. When in the garage and on mute, I drive in some spots where there is signal and when I am there, the music starts playing again. This is annoying. What I think it that in the software when the stream is stopped because of losing signal, there is still a function running to find a signal and if it does, will start the audio stream again. This function should be augmented by checking if mute was on and not just start playing the stream. Thanx very much.
[Android Head-Units] M7R:
I have just downloaded the latest version from the play store, all seems great apart from the favourite list? This doesn’t seem to work? I have added the favourite star next to 5 or 6 stations but when I click the button at the bottom which I guess should make the list show only my favourite stations all it does is turn the stars on and off next to the big list of stations? Is this right?

This is on a android headunit running android 10.0

Thanks
[Android Head-Units] realzoulou:
When you say "mute", what do you mean here?

a) Mute the audio output of the device (volume=0), or

b) pausing the DAB-Z playback using some control, e.g. from a Widget
[Android Head-Units] realzoulou:
If this is the only difference you notice, then it would mean that you have set *all* of the stations as favorites.

When switching from "all" to "favorites only", only the stations, which have been marked as favorites, will be shown in the list. Because it is the favorites list anyways, it does not show the star next to the station name.

Note: You can sort favorites by long-press on the station and then (while keeping pressed) move it up/down in the list. The "all" list cannot be sorted.
[Android Head-Units] mawi29:
Hmm, not sure how to answer, but I use my steering wheel controls to press mute. I guess this is an android function then? Perhaps the widget you talk about?
[Android Head-Units] SaabAero23:
Anyone know where the splash files are located? I want to add my own text and background to suit my infotainment theme, but cant seem to find the files when decompiling the APK
[Android Head-Units] realzoulou:
I tested this myself today with my Android 10 (Hal9k 5.02): When pressing the SWC button to Mute (= volume 0), Android 10 sends a Pause command to DAB-Z and sets volume to 0. When reversing this does not change. When driving forward again, I saw once that DAB-Z got the Play command from Android, but volume was kept 0 (=muted). All other attempts showed the more expected behavior: After reverse and then driving forward, DAB-Z is kept in Pause and volume is muted.

Thus: It seems that your Android after a while unmutes and tells DAB-Z to Play. DAB signal should not make any difference here.
[Android Head-Units] mawi29:
Hmm, interesting. I have to say it's been 2 months or so since I last tested this as I have been working from home and didn't drive much. In the meantime I updated some apps, so let me test this again.
