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

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.
Same here, never had wifi problems with this combination. I'm now using PX6 + Hal9k Mod 4.2.1, also no problems.

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.

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.

Have a look at Ubiquity Music Widget on Play Store. It supports many different players, IIRC also DAB-Z.

@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

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...

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

Usually the head unit dims the display if there is a +12V signal on the ILL/ILLU wire. So there is nothing to remember.

    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.

    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.

    To @ Users from Switzerland... please be patient or join the Beta Channel to get 1.9.114 asap.
    Post #1 contains how to join the beta program in Google Play store. Please refrain from sending direct emails or PN. Thank you.

    @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.

    The app is 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

    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:
    up to 1.9.110 <internal memory>/DAB/rec/
    from 1.9.114 on: <internal memory>/Documents/DAB/rec/
    Download them all from the head unit, zip them and send to me.

    Release ZOU-DAB+171119 "Master Piece"

    Release of the "Master Piece" version of the DAB+ App mod.
    ZOU-DAB+171119

    Credits for translation to Norwegian goes to again to XDA member @[email protected]
    Credits for translation to Italian goes to china-rns.com member John Dai

    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+180618 "Master Piece Maintenance Release 4"

    Release of the "Master Piece Maintenance Release 4" version of the DAB+ App mod.

    ZOU-DAB+180618

    Download: REMOVED

    Changes (see also Changes.txt from the download)

    - Fixed: Adopt Station Logo download to new VW website
    - Add a button to Settings->Info to show hints picture about how to use the UI
    12
    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.
