t98 installed. Observations. Map is no longer flashing but took a very long time to find my position even with a 5 bar internet signal. The other minor issue that I have observed today is the clock shrank. It went down from 32pt to 24pt and the secondary line went from 20pt to 12pt. Also the Player widget normally displays DAB, FM and Music, but had decided to add Standard player. This disappeared after a restart but did come back again. It has stopped doing it now. A LogCat will be posted soonest. Thank you
Is it easily reproducible? Can someone post all steps how to repeat this issue?
I don't see this on my device.

You mean the shrinking respectively altering font size of the Clock widget?

I observed this several times after updating FCC, but not every time. Yesterday I e.g. updated to test99 and it didn't happen, so it's not always reproducible.

If you want to try to reproduce it, please use my backup that I posted here and install several test versions and check after each update. The Speed widget and the Clock widget on my first screen should e.g. have the same font sizes, but for me the font size of the Clock widget doesn't always stick.

Maybe the special thing about my configuration is that I have two clock widgets of different font sizes, one on the first home screen and another one on the second?

Not necessarily easily reproduceable but does happen often after an update and sometimes on restart (not reboot). I will do my best to capture it. Thanks. Testing t100 later.

For test100 version this shouldn't be an issue anymore. Please test.
Ok its partially fixed it. The Artist info is there and the logo for station is there. But when the song changes and Album art changes it shows album art for about 10secs and goes back to station logo. The app has the album art displayed the whole time. Let me continue to test and make sure it's not just this station I'm on, I'll report back.

UPDATE: So if I'm on the launcher screen its random if it updates the Album and Artist info from song to song. If I click into the iheartradio app and go back to launcher home screen it's updated. But than disappears, and repeat process to fix it.

t100 tested. Map took ages to lock on to my location. Only is quick if I toggle Wi-Fi, so this may be a ROM issue?? Clock still shrank. New Logcat made and I will upload today. Thank you

Premium user here...
I downloaded and installed t100 to try the split screen thing, but I have no idea how to use it.
Can anyone point me in the right direction?

This depends on your Android OS (some versions do not support split screen).
Here is a tutorial found on youtube:

To be able to use Fcc Launcher in split screen mode go to Fcc Settings - System:
- check Enable spit screen (the top item) if you see it.
- Select Home app and then select Fcc Launcher (split screen).
Then use general tutorial to put apps in split screen mode

@SpeedFire- I don't get any album art issues at all. The only issue I get that is "a problem" is the random resizing of the digital clock and player widget text size. The clock text reduces and the players i.e. DAB, FM etc enlarges and then wraps. And I have just noticed a button I placed to take me to the TPMS app, the background has gone to a solid colour rather than transparent. I will try and capture it and run logcat again. Thanks

    Yes, I know. :)

    Yes, of course. Also double-checked with Titanium Backup, which shows that original Radio app is frozen.

    Both are enabled. But since FCC doesn't use metadata but only notifications according to @SpeedFire-, I disabled metadata for the testings I just did (please see below.)

    Thanks for the quick update. :) It fixes most, but unfortunately not all of the issues I had with the display of NavRadio+ data in the FCC Player widget.

    The remaining bug is that randomly I see the text "Not provided" instead of the station name, even though the NavRadio+ notification correctly provides the data, please see attached video.

    I didn't have such issues and cannot find the source of this "Not provided" title however I explicitly banned it in this new version: fcclauncher-3.442_test123.apk

    Another small issue that I would like to ask you or @KoTiX2 to fix is that the RDS data currently is displayed as "Artist" and the station freq and name is displayed as "Track" in the Player widget. I would like to have it vice versa (or an option to assign it one or the other way), because then it would be the same as DAB-Z data is displayed in the Player widget. I have "Artist" set in a bigger font size than "Track" and usually station freq and name are shorter than the RDS texts, so this assignment would make sense.
    This is better to be done on @KoTiX2 side
    New test version fcclauncher-3.442_test122.apk
    - I noticed that TPMS widget didn't work well. Now it is fixed.
    - Hal9k updates are ignored when NavRadio+ is installed
    The only change in this version compared to test120 is that I updated all the libraries to the latest versions and targeted the latest Google SDK 32 (Android 13?) instead of 31 (Android 12) previously.

    So we can identify bugs (if any) related to this switch.
    New version fcclauncher-3.442_test120.apk

    Finally, ALL the remaining widgets are rewritten to the new format:
    - TripCombined widget rewritten
    - OBD widget rewritten
    - Contact widget rewritten


    Please test.

    Thanks a lot for the two new updates and congratulations that you finished rewriting all widgets now! :cool:(y)

    I updated from test115 to test121 today and can give you the following feedback:
    1. The Bluetooth widget had adifferent layout after the update (bigger space between logo and text), but I could manually change it to its previous look again.
    2. Also the GPS Satelites widget had a different layout after the update (bigger space between logo and text), but I can manually change this as well again.
    3. The TripCombined widget doesn't show the 2nd texts and I didn't manage to get them shown by adjusting the settings. Please compare the attached screenshots from before and after the update. According to the widget settings (which are the same as before the update) the 2nd texts should be shown, but they aren't, so this seems to be a bug.
    4. The Brightness widget doesn't show the "A" anymore when automatic brightness is activated and I couldn't get the "A" to be shown by changing the widget settings, so this seems to be a bug.
    5. Besides this (not test121 related, but checked with test115 on my MTCE head unit) the Brightness widget still doesn't seem to update to the correct icon according to the time of the day, please see attached video. I took the video in the evening, so the icon of the Brightness widget should have been at low brightness already, but it still showed full brightness. Only after cycling through the brightness settings by tapping on the widget, the correct icon is shown, as you can see in the video. The auto brightness function of FCC itself seems to work well, only the icon display is wrong.
    I don't use the OBD widget (which doesn't work on my system) and the Contact widget, so I cannot give you feedback about them.

    Please let me know when you need any more infos or testing. I'm looking forward for the remaining bugs to be fixed, so you can release the new version on Play Store. :)
    This is probably because Google Maps have some interesting bug/feature. It doesn't download new tiles while camera is moving. I leave some time (several milliseconds each second) when camera is not moving during which Google can download data. If mobile speed is not enough it may fail to download everything during this period. When you drag the map camera is not animated and it downloads the data.

    I saw that Google released a completely new Beta of their built-in maps SDK with new rendering capabilities. Now it is deprecated and will be part of a normal library update:
    So maybe I already switched to this new map SDK when updated Google Libraries.
    Today I also checked if the Minimap display bug is still existent in test121 and unfortunately it still is.

    Thanks to @rigattoni's tip I used Mock Location app to record a short video of how this bug looks like, please see attachment.

    As you can see in the video, the map tile ahead isn't fully shown, but just the underlying colored areas. Only when swiping the map (at 0:00:10 in the video), the missing information/layers are immediately shown.

    I actually don't think that this is mobile data (or the speed of it) related, because it also happens with map tiles that should be already in cache.

    Happy New Year @SpeedFire- and all users of FCC Launcher! 🍾🥂
    Happy New Year everyone!
    You are what drives the app development and motivates to change it.
    I am really excited about our community!
    You are the best! Happy New Year! :love:🥳🎉
    Happy New Year @SpeedFire- and all users of FCC Launcher! 🍾🥂
    I tried this now on my phone (Galaxy A5 2017, android 8), clean installed test113, set up new player widget and it is the same as on my head unit. The logo is not fit correctly.
    Here is a fixed version: fcclauncher-3.442_test114.apk
    It turned out that album art was cropped to square by default.
    Now I've added an option to the Player widget settings (crop is now disabled by default)
    Happy New Year @SpeedFire- and all users of FCC Launcher! 🍾🥂
    Yes @SpeedFire- You deserve it from the FCC community

    Thanks! I reproduced this on my Samsung device as well. I will investigate this.

    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).
