DAB-Z doesn't closes by itself /pauses playback if I switch to Headunit Reloaded and starting audio playback there.
If I start another audio app on the head unit (e.g. Black Player) DAB-Z stops how expected.
To stop DAB-Z playing in first case I have to use the app switcher to kill it. Not really funny while on the road.

Any ideas? Is there another way to silence DAB-Z?

1. broadcast Pause intent
2. In DAB-Z app screen press "back" button
3. (most preferred as it would work automatically :) ) Tell "Headunit reloaded" (no idea what it is) to use standard android functions for playing music - in that case DAB-Z detects, that other media application plays music, and therefore stops (as it do with any other music players e.g. Black Player).

I thought using DAB-Z and Headunit Reloaded is something like a standard.

@realzoulou :
I found a small issue with Service Following. When the signal disappears for few seconds (i.e. in the city tunnels), correctly the Service Following starts to search alternative frequencies. After that, since the alternate frequency is not found, the app return to the previous one that in the meantime is back. But, at this point, the signal strength is zero and audio is lost. Changing the station and coming back to the previous one it starts to play again. Is this behaviour correct ?

After a failed attempt to search for alternatives, it goes back to the station where it was before SF was attempted. This is expected behaviour.
The failure you saw (no signal bar, no audio) is likely due to a random failure, which I basically know about, but don't understand why it happens. It's in the lowest level part of OMRI, which talks to USB.

Since a few months a have the following problem.
After turning on the car and the unit, DAB-Z app starts automatically, the interface is working and the signal reception is shown correctly with the red/yellow/green bars. But there is no audio output to the speakers. I always have to close and restart the DAB-Z app, after that it is working.

Unit is a PX6 and I am using Android 9 with hal9k mod (latest version).

It works again when you turn off OMRI.
Their is an issue with the new DAB-Z Version.

i made a trip to Austria last week, and heard mostly DAB+ radio on my way. Have some thoughts/suggestions/reports:

1. While service following works good when signal disappeared completely (thumbs up!), in several areas i had issues with reception. After scanning of new stations i have seen, that this station exists with same name on other ensembles, and can be triggered manually to search other station via SF. Could be that done also automatically in some cases (e.g. when reception has no audio in 4 seconds from last 10 seconds of reception)? the problem is that in such border areas you can still get signal from far transmitter, but audio will be interrupted quite often - let's say 1 second of audio following with 2 seconds of silence because of weak signak from that transmitter.

2. some stations show its name without the last char. I tried to clear station list and rescan - same problem. This bug appeared since ~2 months (?). I assume that it has smth to do with string encoding, because the names with missed last char have umlauts in names ("RadioRüsselsheim", "MDR Thür Mitte-W"), but not always names with umlauts are getting cut (e.g "MDR Thür West" is shown completely). I have looked into the logcat after station scanning, but haven't seen there anything that points to misbehaviour. I still can send you log if you interested. I have also checked those names on my kitchen DAB radio - it shows full names, doesn't cut last char.

3, 2 times i had a bug when after station scanning the progress window stayed in front of app forever - "cancel" button hadn't helped, a station started playing in background, but it was not possible to switch to other station. So the only way to get it working again was to close app from recent app list and restart DAB-Z.

I am using latest beta version in OMRI mode on Intel SoFIA (x86) + Android 6.0.1.
Thanks.

I've experienced this once, too. Android 9.

@realzoulou I bought a new HU (UIS7862 Navifly 6+128GB like Teyes CC3) and installed with same hardware of previous PX6 RK3399, same DAB hardware (usb stick and antenna) but it seems that on UIS7862 signal is often go and down, with no way to listen enough well. Sometimes you need to reinstall apk (both 1.8.105 and 1.9 Beta), and station list is empty twice. After some enter and exit, station list (90 in my area - NW Italy) will appear after scan. I think that there is incompatibility (or not?) with UIS7862, isn't it? If you wish I can help you to perform onthis platform, tell me what you need.

I tried it last night with my Samsung Galaxy S10 (OneUI Android 11). Unfortunately with the same problem. Maybe the higher Android versions cause this problem. Unfortunately I don't have a device with older Android to test it out.


Edit:

I just noticed that the harmony.fm and planet radio work again when I deactivate the OMRI mode.
Same here, station search does not find any station on channel 6A in OMRI mode

    It can be installed in parallel to any original preinstalled DAB+ Player.

    Get DAB-Z on Google Play

    Get previous versions on Apkpure

    Pumpkin Y0251
    Hotaudio Dasaita DAB+
    (and dozends or hundreds more, they are all quite the same, if not equal)

    NOT SUPPORTED:

    * Any SDR ("Software Defined Radio") devices (e.g. based on Realtek RTL2832U R820T)
    * Fulljoin adapter
    * Dension DAB+U
    * Dasaita DAB box



    For testers that want to actively support me and help everyone to have a better DAB-Z app:

    If you encounter an issue with DAB-Z, I will maybe ask you to provide a) logcat logs or b) raw recordings.

    a) logcat logs are created by pressing the logcat button in DAB-Z Settings -> Info (at the very bottom)
    A zip file is created and you will be able to choose what to do (send via Email, add to Google Drive, etc...). Get this zip file to me somehow.
    If I additionally ask you to enable "OMRI verbose logging", then follow these steps before creating the logcat as above:

    1. Enable Developer Menu: tap 7x on Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
    2. Enable OMRI verbose logging
    3. Close DAB-Z
    4. Reopen DAB-Z
    ... reproduce the issue ...
    5. Create the logcat DAB-Z Settings -> Info (at the very bottom)

    b) raw recording are created by this procedure:

    raw recordings are done using this procedure:
    1. Enable Developer Menu: tap 7x on Settings->Info->Version , then go back, a new menu item appeared "Developer options" at the very bottom
    2. Enable OMRI raw recording (you don't need to activate verbose logging)
    3. Close DAB-Z (raw recording enable/disable requires a restart of DAB-Z)
    4. Reopen DAB-Z
    ... reproduce the issue ...
    6. Go to DAB-Z Settings and disable OMRI raw recording. Restart DAB-Z again.

    Afterwards, files with ending .raw exist in:
    • DAB-Z version: 1.8.xxx: /DAB/rec/
    • DAB-Z version: 1.9.xxx: /Android/data/com.zoulou.dab/files/DAB/rec/
    Download them all from the head unit, zip them and send to me.

    Changes (see also Changes.txt from the download):

    New:
    - Station logos
    Station logos can be downloaded from Volkswagen for >20 countries across Europe and automatically installed to a User accessible location. More than one country can be installed. User can add own station logos in subfolder "<extStorageDir>/DAB/logos/user" in JPG or PNG format. No width/height restrictions for the logo. The app will automatically scale to fit.
    Settings allow to enable/disable showing station logos in station list and in Slide Show area. Scaling can be limited to 1x,2x,3x if needed.
    Settings list any issues in finding a matching logo for a certain station. The search is based on the station name. If no exact (substring) match can be found in the list of logo files, then a default logo is presented. The User has to fix this by renaming logo files or adding additional logo files outside(!) of the DAB app using a File Manager.
    - Layout:
    * new button icons
    * button bar moved from left to right side to gain more space for the slide show area
    * Changed the "logic" of the favorites button: Shows what will happen when pressing it, not what the current status is.
    * new "radio.png" logo. Using now a new DAB logo used in Germany (www.digitalradio.de)
    * the background boxes are not disabled by default. Can be reactivated in Settings.
    * General layout optimization for
    - 800x480 @ 320 dpi
    - 800x480 @ 240 dpi
    - 1024x600 @ 320 dpi
    - 1024x600 @ 240 dpi
    - Removed the previously added "Large SLS" activity. Replaced with an animated fade out of the station list.
    - Added an option to automatically hide the stationlist after a selectable timeout.
    - Added Audio format (MP2 or AAC) and Sample rate (44,1 or 48 kHz) to Station details. As before in the Large SLS, still accessible via "flipping" the slide show picture.
    - Added an option in Settings to move the App to background when the DAB App was started by the "USB device attached" event. Useful eg. when using certain launchers.
    - New logo in the notification bar.
    - Settings->Info shows the reason why the DAB App is running: Either started by "LAUNCHER" or "USB DEVICE ATTACHED"
    - Settings->Info shows the screen resolution and density (e.g. 1024x600 @ 160 dpi)
    - When scanning with type "update", old stations no longer received are now deleted. The favorite setting will be kept.
    - Added Italian translation. Thanks to John Dai @ china-rns.com

    Changes:
    - Replaced old "Connecting..." behaviour with a completely new implementation
    - Audio recording now stored in <extStorageDir>/DAB/rec/ (instead of <extStorageDir>/dab_rec/)
    - Fixed: Channels "10N, 11N and 12N" not shown in station details
    - for developers: BroadcastIntent generation is now disabled by default. Can be reactivated in Settings.
    BroadcastIntent definition has changed w.r.t. "artist", "track" and "playing". See change documentation in BroadcastIntent-definition.txt

    Note that the high pitch sound issue is not fixed in the 171119 release.

    Release ZOU-DAB+180804 "Master Piece Maintenance Release 5"

    Release of the "Master Piece Maintenance Release 5" version of the DAB+ App mod.

    ZOU-DAB+180804

    Download: http://bit.ly/2Kqp7HB
    (Please only share the bitly link with others)

    Changes (see also Changes.txt from the download)

    - BroadcastIntent: added slsBitmap which contains currently displayed logo or DAB slideshow picture
    Goal: Allow launchers (e.g. FCC Car launcher) to display album art
    INFO: DAB App now also has a fairly complete implementation of Android's android.media.browse.MediaBrowserService interface
    This allows for using pure Android APIs to view metadata instead of using the proprietary BroadcastIntent
    - Add buttons for PREV and NEXT to Notification and use Media style notification
    - PREV/NEXT steering wheel behavior can be swapped in Settings->General
    - Fixed: Volume adjustment in Settings->Audio is lost after station change
    - Fixed: After several station scans, App completely fails to work until re-install.
    - Fixed: Duplicate entries in station list
    - Removed feature to delay the USB connection on automatic start, which was introduced with ZOU-DAB+180210
    - Removed option to avoid that DAB App is started twice from Settings->General. This is now avoided by using Android manifest launchMode=singleTask
    - Removed feature to download a country-specific station logo zip file and automatically extract it.
    Note: You can still copy an extracted folder of such station logos to /DAB/logos/ folder and after pressing "Sync" button in Settings->Station Logo the logo files will be scanned for a match between filename of a png/jpg file and the name of a station.

    Release ZOU-DAB+170909

    Release of my next major version of the DAB+ App mod.
    ZOU-DAB+170909
    This is not the "master piece" release yet.

    Download: REMOVED

    There are (again) two versions of the App:
    a) the "normal" one
    b) one with no usb_device_filter.xml included, which makes Android remember already granted access of DAB+ App to the USB DAB device.
    However, Android then also starts the DAB+ App whenever it finds the USB DAB device as newly connected, which is the case when you power on the
    head unit.
    Some people don't want that the DAB+ app starts automatically when the DAB USB device is detected at startup. This is the reason why this version exists.
    Note: When running on Android >= 6, this version will most likely ask for permission to access the USB device at *every* start of the app.

    Changes (see also the Changes.txt from the download):

    New:
    - Most (not all) of the texts are now available in: English, Deutsch and Norsk bokmål
    Credits for translation to Norwegian goes to XDA member [B @[email protected][/B]
    - Swipe to right in station list shows a delete button. On swipe left again, delete button disappears. On click on delete button an alert dialog appears to allow the user to confirm. Deletion of stations cannot be un-done. A new scan is needed to get the station back.
    - Additional info (channel and ensemble name) in station list can be deactivated via Settings->Layout
    - "Service Following" feature can be activated in Settings->General. NOTE: This is treated as "Experimental". This activates the original app functionality, which was always in the app, but was not connected to the UI. Do not blame me if you find it not working.
    - Audio recording button can be activated via Settings->General
    - The borders around the slide show picture and around the station list can be deactivated via Settings->Layout
    - A click on the slide show picture creates a large version of the picture. I call this "Large SLS".
    - Swipe left or right on "Large SLS" switches between the picture and some detailled info about the current station.
    - When starting a re-scan one can choose now between "Replace all stations" and "Add new stations"
    - The app sends out broadcast intents containing all information that you can also find on the screen.
    The definition of the intent is in file "BroadcastIntent-definition.txt"

    Changes:
    - Fixed: no audio after standby when using NoKill mods.
    - Fixed: when USB connection suddenly drops, the App remains active but with no audio. My fix is to close the app.
    - Settings layout improved
    - Notification now contains station name instead of "Make DAB+ great again ..."
    - A second way to enter the settings screen is via the "Large SLS" screen
    - Optimization of memory allocations. Results in less Garbage Collector runs, which is good for overall performance.
