I am trying test 10 and I have to say that now it is better with widgets. Only sometimes it happens that the scaling sliders do not exactly match the touch but overall it is much better than before. I bought this Launcher because it integrates all the tools inside that you have to install separately such as assigning custom actions to the steering wheel controls or the volume control based on speed without using a specific apk (which no longer works on Android 10). The automatic start of applications after sleep is also important (included only in the Rom mods) but the waiting time should increase a little to at least 5/6 seconds because there are some apks that take longer to start. I have yet to find out more about this Launcher after which I'll give a more certain assessment. Camera ruler view doesn't work for me. Always keep developing, thank you

Here are some intermediate results with a new Alpha - fcclauncher-3.442_test8.apk

1) These widgets are upgraded to the new customisable format:
- TimeDigital
- IconWidget
- TripDistance
- TripAltitude
- TripSpeed
- TripTime
- TripParkingTimeLast (a new separate widget - previously was a part of Trip Combined)
- TripParkingTimeToday (a new separate widget - previously was a part of Trip Combined)
- TripStreetname
- AccVoltage
- VoiceWidget
- SatelliteWidget
- RamWidget
- SpeedLimit
- PageWidget
2) Yandex MapKit migrated from 3.5.0 to 4.0.0

I will continue to upgrade other types of widgets, some of them are quite complex as Player Widget.

Please give a feedback how new widget work as well as the app itself.
Good day.
After upgrading to test10, the Compass widget disappeared.

    you're right, the compass is no longer there .. "Speedfire" you find yourself correcting, you also add an analog spedometer 😜I know I'm repetitive ..
    Sure. All the "analog" type widgets will be added in the next test versions: Analog Time, Analog Speedometer, Compass widgets.
    They are very similar by their nature so they will be added together when ready.

    In the test10 version you can select custom delays between apps in autostart (from 1 second to several minutes).

    No backup is possible in my HU with Android 10. Loading backup is not problem. I use version 3.442 FCC from the market, there is no problem on a tablet with Android 10, it is not possible in HU.
    HU / FCC has a problem with creating Folders, the offline map could not be downloaded, I manually created the MBTitles folder and then downloaded it.
    But backups don't work.

    Test10 keeps asking for default launcher every time I push the home button in my HU
    Also TPMS add-on doesn't start automatically (in background) like it should be if at least one TPMS widget is active

    Are you sure you select "normal FCC launcher" and not split screen?

    With test10 it's possible to edit widget thanks

    Can I suggest to add USB Odb2 also?

      Backup/restore works perfectly for me on t16
      i hope this 8s better
      Yes! This one is good. Congratulations, now you can record proper LogCat logs.
      I will look into it in details soon.
      I didn't find the exact reason for this Home button issue (because I can't reproduce it on my emulators) - please provide more details what OS version and devices you use. Is it only with a Split screen version selected?

      In this version I've made some changes. One of them - I completely removed the "black screen with a logo" showed while Launcher was loading. Do you like this version or the previous one? Which version seems to load faster?

      Will try tomorrow morniing, here in france is 01h06am June 25th

      First of all, let me compliment the dev for a very nice car launcher, I love it.
      Apart from that, I wanted to report a couple of possible bugs.
      1. The media widget gets stuck sometimes, it just shows the same song/album art, even if I change the track; also, the same widget sometimes doesn't show the song/artist info; all these problems are temporarily fixed if I restart/rebuild the widgets;
      2. The artist/song animated band included in the same widget only shows a part of the data (if it's a long title);
      3. I registered on openweathermap.com, but the weather widget doesn't accept the code;
      4. On startup, the system shows the original launcher, even if FCC is the default one. If I press the home button, it immediately switches to FCC.

      PS: using a music player named AIMP on a ZXDZ_01 Android 10 head unit.
      Thank you
      Thanks! I am currently rewriting all the widgets. Player widget will be one of the next. I hope such issues will be resolved.
      Backup / restore should work here: fcclauncher-3.442_test16.apk
      Backup / restore should work here: fcclauncher-3.442_test16.apk
      The test16 version fixed the home button issue on my device! Thanks a lot for this!
      Here is an alpha version with a possible solution for a Home button reload behaviour.
      Please test: fcclauncher-3.442_test12.apk
      Root does not influence this.

      Can you please check this test15 version: fcclauncher-3.442_test15.apk
      It is half-baked. So it should create backups in /sdcard/Download/Fcc_Launcher_Backup/ (please check using any file explorer)
      But it can't see and restore them.

      If it actually creates backup on your device I will continue to work this way to be able to restore.
      test15 tested

      Backups both GDrive and local = OK

      FYI: this version stills asking for default launcher (normal or split) when returning home !

      Hi, all!

      Welcome to the official thread for FCC Car Launcher - a customizable auto launcher for android head units (Rockchip MTCB/MTCD+ and FlyAudio) as well as android smartphones/tablets.

      Its major features:
      - Full function launcher with supports of all standard third party android widgets
      - Deep integration with head units (MCU etc). My mission here is to implement as many functions in the launcher itself as possible. In case of Rockchip devices to get rid of most xposed modules (my deep respect to their authors, great job, but they sometimes slow down the device significantly) and replace them with the normal built-in functions.
      - Customization. The FCC Cat Launcher has some built-in customizable widgets which can help to make your home screen more personal (you can adjust widgets size, colors, features etc).
      - Built-in music widget with support of FM Radio (with ability to give names to radio stations), Spotify, Google Music, PowerAmp, PC Radio, Neutron and Stellio players.
      - One-click navigation widgets with quick route building (supports Waze, Google Maps, Yandex Navigator and other navigation apps).
      - Phone calls via connected phone using 'Ok Google call [name]' request or by clicking on built-in Contact widget.
      - Other features.

      1. I love MiniMap but can you put other navigation app there?
      Unfortunately this is not possible. MiniMap is part of FCC and is based on Google Maps API for Android. It is not another app (not even a Google Maps app), that can be just replaced within the FCC interface. Android does not allow to integrate third party apps (navigation apps) inside another third party apps (FCC Launcher).
      If your head Unit supports Split Screen (ie can display Two apps at the same time), this can be partially done with split screen.

      2. Is it possible to cache maps for MiniMap for offline use?
      - Yes. In the latest FCC Launcher beta version you can select Offline Mapbox map and download it to your device.
      - For Google Maps - No. Caching is directly prohibited by Google license for using Google Maps API (MiniMap). Moreover, Google even does not provide developers with such a caching API. Therefore you will need a constant internet connection to use MiniMap. The somewhat good news is that the map itself does some short-term caching on your device, so it saves some data (but not too much).

      3. Notifications are only popping up for a split second / flashing. How to fix this?
      That means that animations are disabled on your device.
      - Go to the device's Developer settings: FCC settings - System - Advanced - Developer settings (if it asks for code - it's "7890" for AllWinner T8).
      - Scroll down and change 3 parameters "Window animation scale", "Transition animation scale" and "Animation duration scale" from "Animation off" to "Animation scale 1x".

      4. Routing on Google Maps in MiniMap doesn't work. It asks for API key. What should I do?
      - Turn-by-turn navigation in built-in Google Map fragment is directly prohibited by Google. Therefore it is not possible to use it. .However if you have your own Google Developer account (Google Maps API key) you can use it to draw a simple route line on the MiniMap. Please note that it will NOT have any turn-by-turn data like distance to next turn or estimated time of arrival.
      I do not recommend to purchase Google Developer account just for this feature:
      - Google Developer account will cost money for you (a one-off payment) which is reasonable only if you really want to develop android apps.
      - Routing requests cost money. But currently Google provides a 200$ per month free usage for Maps, Routes, and Places every month which should be enough for individual usage.
      Links: Get API key, Pricing. Don't forget to enable Maps API and Directions API in your Google Cloud Console.


      Translation to your language
      Guys, many of you suggested your help with translation of the app to your native languages.
      I have setup a translation project on OneSky site.

      channel: https://play.google.com/store/apps/details?id=ru.speedfire.flycontrolcenter
      Beta channel: https://play.google.com/apps/testing/ru.speedfire.flycontrolcenter
      (I would suggest to stick with the release channel since beta channel can be really buggy sometimes and is intended for beta testers only)

      As a developer I will be happy to discuss with you any ideas or issues.

      Here is a couple of tutorials:
      1) Quick look on home screen setup process:

      How to write LogCat log:
      You need to have ROOT:
      1. Install LogCat Extreme LogCat Extreme
      2. Select VERBOSE level of details (very important) Video 1
      3. Write and send log: Video 2

      Initial setup (do this if you see black screen):
      Important checkbox during first setup:

      Please make sure to check that checkbox "Always allow FCC Launcher to add widgets..".

      Full setup process:
      pity that the developer is not dedicated to solving several bugs of this fantastic launcher, too many bugs for daily use is not so good unfortunately

      How the Hell can you say that when @SpeedFire- has dedicated 100's , if not 1000's of hours developing this launcher, and for peanuts !!

      I remember a time last year when he was on vacation, and even then, each night he worked on FCC, fixing bugs and greatly improving what was already there.

      FCC is probably one of the most COMPLEX apps on Playstore.

      My understanding is that he basically developed FCC for HIMSELF, because he was not satisfied with what was currently out there, and was good enough to share his work with anyone wanting to try it.

      Because of technical complexities, this launcher is designed and developed for a limited number of Android systems, but that number is increasing all the time as he add new Units to those currently supported.

      If you go out and purchase some obscure, budget China unit, that is not supported, you cannot blame anyone but yourself, if then you experience issues.

      Just because you paid the developer a few dollars because YOU CHOSE TO DO SO does not mean that you OWN him, and can demand that he jumps at your every call ... it's not his work -- it's his HOBBY -- and you probably knew that going in .. so lighten up and stop giving him such a hard time.

      BTW, I am also a developer, and I can tell you, if anyone else got involved in this complex app, it would most likely get totally screwed up, and dye -- that is assuming one could even find someone who would be willing to put in the time for next to nothing, while having the technical ability to actually contribute anything to the project.

      Thank you @SpeedFire- for clearly the best Android launcher on the market, and for all your time and dedication in constantly improving it. It is very much appreciated I am sure by the majority of those using it, and you will always have my full support going into the future.
      It seems that I've found the best solution for Normal / Split-Screen modes. Take a look:

      Here is a short demo of two modes in the alpha version:
      1) Normal mode - launcher does not support split screen (bad) but behaves as a normal launcher and is not visible in the list of recent apps (good).
      2) Split screen mode - launcher supports 50/50 multi window mode (good) but is visible in the list of recent apps (bad).

      Every user can select the preferred mode!
      The app is now returned to the Play Store :)
      New beta is out:
      - All skins are re-designed for 6x10 grid (instead of previous 6x7 grid). You need to re-apply skin if you want to switch to a new skin.
      - You can choose your favourite skin during first time setup process.
      - Time widget has new options to granually change Time and Date font sizes as well as to swap Time and Date positions
      - Re-written code for album arts in Player widget. Hopefully this will fix most issues.
      - Some other fixes.
      - For built-in skins Icons are automatically setup when put on home screen or moved (based on skins' settings for particular Icon slot).
