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.

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.

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.

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

The splash screen replaces the previous small popup only covering a small portion of the screen, which allowed the wallpaper to be visible.
Because this looks (on some devices) as if the Launcher had crashed, I decided to introduce a splash screen instead.
The splash screen is shown only as long as necessary and does not slow down the start of the app.
So, the "time to first audio output" is not impacted by the splash screen.
Because I also decided to show the status of the App startup as text on the splash screen, this results in the text (not really interesting anyway) being nearly not readible, especially on fast devices.
Therefore ... here is a slow motion of the splash screen :)



P.S. No, I am not affiliated with "ANTENNE BAYERN" and also do not earn any money by showing them quite often on my material for DAB-Z.

DAB-Z release 1.9.116 BETA

* 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
Thanks for the new beta version. :)

There are some issues with the new splash screen:
  1. 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).
  2. 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. :)

P.S. No, I am not affiliated with "ANTENNE BAYERN" and also do not earn any money by showing them quite often on my material for DAB-Z.

Hehe. Also I'm not affiliated with "WDR", which is shown in my videos, it's just my "Haus und Hof Sender". ;)

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.

@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.

@NogenLunde Could you execute this command in order to see what CPU governor is configured for your device?
Bash:
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.

@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.

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...

"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.

    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.

    Record button *always* records live audio only, never timeshift.

    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?

    Release notes of currently active release on Google Play 1.9.115
    Release notes of currently active PUBLIC BETA on Google Play: 1.9.116
    If you want to become beta user, subscribe in Google Play or open this link from the device : https://play.google.com/apps/testing/com.zoulou.dab

    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

    Compatible devices:

    all DAB USB dongles with VID/PID = 16C0/05DC (decimal 5824/1500) ("VOTI", "Van Ooijen Technische Informatica", "shared ID for use with libusb", "[email protected]")
    Examples (for sure not complete!)
    XTRONS USBDAB01
    Joying DAB+
    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

    Download: REMOVED

    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.
