How Do I: Hide date, Settings icon in Notification curtain

Greetings all,

CPU: RK3188 1.6GHz Cortex A9 Quad Core

Screen Resolution: 1024*600

OS: Android 4.4.4 kitkat

ROM: Malaysk 20150909

I am new to XDA and HuiFei radios.

I have setup my new radio and am pretty happy with the look.

There is one item I am trying to remove: The date and settings button from the Notification curtain (see attached image).

It only shows when I pull the notification curtain down; when viewing my launcher homepage, THAT date and settings icon do not show--which is good.

Is there any way to remove it?

Thanks!

PS: I cannot add a link because I am new :(

Are you sure it did not work? Did you unzip the MCU image if needed prior to copying it to your gps card? Also, did you check your MCU version in Settings > About. Normally if you can select the sd card in recovery, it will flash the new MCU image even if there are some failed firmware install operations displayed during the update.

If you are able to access recovery and select the sd card, it should work. If you can not access recovery, below are a couple options to gain access.

First make sure you have the unzipped MCU image on your gps card.

1) Press reset button and power button together

2) After about 5 secs release reset button, but keep pressing power button

3) When booting screen appears release power button.

4) It boots into recovery.

5) Once in Recovery, you can use your Power - Volume Button to scroll to the appropriate image location and then press the Power Button for a few seconds to start flashing the new image. That said, I'm not sure of your exact JY unit so you may need to try different button presses to scroll and select.

Another option is to download and install Quick Boot from Google Play, and use it to boot into Recovery. Once in Recovery, again, you can use your Power - Volume Button to scroll to the appropriate image location and then press the Power Button for a few seconds to start flashing the new MCU and or Update image.

Hope this helps...

Best to all,

Hi,

I have the same problem. Same HU behavior on stock and Malaysk ROM. I tested various MCUs with no positive effect. Each time I switch off ACC unit shuts down and I can see USB unmounting (storage unexpectedly removed) message. After a few seconds when I switch on ACC unit starts mounting USBs and restarting services. Daily Records very often fail to restarts (whereas in cold boot it starts fine in 90%), stock music application (if it played before) restarts fine and wait for USB to mount but always starts with the first song on the playlist. If I switch off music apk before switching the ignition off then headunit will remember the last played song when application is started manually (during next boot). I have my music on pendrive, not on GPS card.

I'm wondering whether it's something related to USBs unmounting. Maybe they shouldn't unmount immediately after AAC off.

My car is Suzuki Grand Vitara 2007 year. I tried various cunbus options in factory settings (SWC worked fine in every configuration) but no success with USB .

Is there possibility with PCV to incorporate some delay in starting/restarting services that rely on USB? I'm thinking of DR voyager to wait longer for USB to mount before it starts recording. Can I set it manually in installrecovery file?
[MTCB Android Head Units Q&A] sluden:
Thx for the answer.

when i downloaded the mcu from links on this page it didnt work, then i tried to download mcu and update from Joyings page. Then the mcu worked.

Of course i unzipped it :)

But i still cant flash the update.img not the one from xda links or from the joying site.

i have tried from recovery, it wont work there either.

there where no problem from the original "rom".

strange, it doesnt seem like there are any others with the same problem.
[MTCB Android Head Units Q&A] Babss:
I have a same unit and same car (pumpkin quad core, 800x480 KLD2 and 1999 E46 320Ci)

So you can use the SWC. Can you remapping with these canbus setting?

Now my canbus setting is NONE and working the SWC but I cannot remapping..

The radio setting is different for me (6686 or something similar)

Hi guys.

I just got an OBD2 unit off ebay and I can't get it to work with my unit. Works fine on my Galaxy S5 but when I go to pair it in bluetooth on the unit it doesn't ask me for a pin and says it pairs. In Torque it just says "bluetooth turned off" or something like that and I can't select it from the list of devices.

I looked in the wiki and downloaded and installed xposed with the xposedMTC module. changed the BT OBD override to the name of my device (obd-2), restarted but nothing changes, still the same problems.

can anyone shed some light on this? I'd love to get this working.
[MTCB Android Head Units Q&A] jordanow:
Did you do like in this video ?
[MTCB Android Head Units Q&A] marty_s13:
I did do that yes. My torque version seems a bit different to that though.
[MTCB Android Head Units Q&A] devilsoft:
That option is enabled only for players like Poweramp, Spotify, MX Player, etc.

I can simply change the XML to enable USB mount option for all the apps from the list, no problem.

I'll try to release a new version of the app later today with changed XML.
[MTCB Android Head Units Q&A] marty_s13:
Ok I got the OBD2 working using the .apk from the OEM folder as per the video, is it possible to get dashcommand working instead? I also installed Malaysk rom without the next launcher and love it.

Is it possible to remove the persistent head unit service is running etc in the notification drawer though?

Hello,

My JY (dec 2014 RK 3066 800X600) touchscreen is out of order (i can work unit with mouse still) I have gave up negociating with hopeless seller, Mekede.

Has anybody experienced this HW failure ? (Not rom related, flashed twice and back to JY stock rom) is it worth changing screen ? where to buy ? any idea of cost ?

many thanks

Anyhow, I apologise as I didn't fully explain myself properly... The "Security" menu is actually present, however it doesn't allow the user to lock the device on boot. It has 3 sections - Device Administration, Credential Storage & User Experience Program. My mobile phone (Motorola Moto X running Android 4.4.4) has more sections within Security titled Screen Security, Encryption, SIM Card Lock & Passwords.

This evening I installed an app called "Hidden Android Settings" by 0alex. This allowed me to access the screen where the user sets up a unlock pattern, but sadly there does not seem to be a way to activate this on boot. I accessed another hidden menu for SIM lock, but it would not accept a PIN - possibly because the device does not have a SIM. So, it seems the menus are there, but it would be great if we could find a way how to make them fully functional.
[MTCB Android Head Units Q&A] gguevara:
Hi agentdr8,

I'm wondering if you might have a solution. GPS apps like iGO use .ogg files for prerecorded voice driving instructions (turn left, turn right, etc). The android volume setting that is dedicated to the gps app works fine with this combination.

However, when using TTS voices (text-to-speech) for driving instructions, the gps app used the selected android TTS engine. This causes the audio stream to generate from outside the gps app, and instead is coming from the android TTS audio stream. Because of this, the android volume settings dedicated to the gps app do not trigger. So music/radio never mutes when the gps starts talking. They both play at the same time.

Is there any xposed module that overrides android volume settings when the gps is in use (regardless of whether regular voices or TTS voice/engines are used)? Or some type of script/modification that needs to be done on a system file?

Can you please help me with this, if possible? I would like put in a request for this. Donations await :)

Thanks,

ggee
[MTCB Android Head Units Q&A] Gona80:
Hi

I'm new to this thread. I have switched from the C200 because in the end it has lost data every 3rd day.

Now I have bought this unit (Pumpkin rk3188, 4.4.4):

http://www.autopumpkin.com/car-dvd-...-3g-wifi-canbus-7-color-buttons-1024-600.html

Maybe some of my questions have been answered but it's nearly impossible to find something in this mega thread.

1.

My unit has the following version numbers:

MCU; MTCB-KLD-V2.71 build 07082015 09:25:38

Build rk3188-eng 4.4.4 10082015 09:33:29

I was unable to find any download links of that version. All versions I've found are older.

Can anybody tell me were I can find a copy of my version? I want to have a backup before starting to use custom roms.

2.

I was able to enable root with factory key: *#hct#root#

3.

Were can I get 1024x600 TWRP? The download link at the beginning of the thread is dead.

4.

On the back is a USB header for which I don't have supplied connector. Can this connector be used for ADB? Does anybody have a pin layout?

5.

"OK Google" (Google App) is not recognizing the microphone. Should I try to replace the version which is part of the system with the version provided in play store?

6.

When using my navigation app (Navigon) the keyboard block the whole screen. In general everything on the screen is very big. I think the reason is that dpi is too low. How can I change it?

7.

How can I change the subwoofer volume? The slider is missing in equalizer.

Thank you very much for your help
[MTCB Android Head Units Q&A] qtpie70:
Yup, you are right. I used h2testw app to test read/write/verify my microSD and found that it can only read/write 6.5GB, not 32GB. Damn those Chinese Ebay sellers. I thought that I spent $11 for a 32GB Samsung EVO card, and it should be real.... but I got scammed. I ended up buying another Samsung EVO 32GB card from local Walmart, tested with h2testw to make sure all 30GB can be read/written from/to the card. This card works fine in my Head Unit.

Hello guys! I'm working on Androidiani (italian's forum) to implement AF function in radio app. We have obtained good results, but now need a list of alternative frequency, that in source code isn't.

The parameters of radio (quality of signal, info rds etc) are implemented in AudioManager and recalled from the radio app, via getParameters(String key) method.

For example, to get signal quality, there is "sta_radio_signal" string...

I need a correct string or all string used into AudioManager to get a AF list, or another method...do you know how to do that?
[MTCB Android Head Units Q&A] agentdr8:
Hmm, it might be possible to redirect TTS audio to a different stream. By default, if the stream isn't specifically defined in the app that's using TTS, it should go to STREAM_MUSIC. I'm guessing the non-TTS audio is being sent out to STREAM_NOTIFICATION or STREAM_SYSTEM (more likely the latter). If I have a chance I can take a look at the iGO app and see if it's easy enough to redirect the audio there.

Can you link me your specific iGO apk? There's a chance that all of them use the same methods, but this way I have some way to test the expected behavior as it applies to your use-case.
[MTCB Android Head Units Q&A] gguevara:
Hi agentdr8,

First I want to say thank you so much for helping :laugh: :good:

I have been reading a lot of the gps forums and working with some to see if there is a final solution to this. This issue is not just specifically an iGO issue. It affects many of the other GPS apps that use android TTS engines. iGO8, iGO Primo, Sygic, TomTom, Navigon (just to name a few). And it also doesn't matter if you select the default google TTS engine, or install a 3rd party TTS engine and select that one instead (SVOX, Ivona, Nuance, etc). Even though I am looking for a solution for our head units, there are also many reports of this issue affecting other android smartphones and tablets as well.

Anyways - as you know, under Android\Settings\GPS - you can select your GPS app (in my case iGO Primo v9.6.7), and you can also select the volume option (Switch or Mixing). Switch simply mutes the music stream (radio, iPod, MP3, CD) when the GPS is talking. Mixing lowers the music stream to a user preset volume when the GPS is talking. Both these processes work fine when the GPS app is set to use non-TTS voices (regular voices - .ogg). However, when the GPS app is set to use TTS voices, then the android TTS engine synthesizes the voice. This TTS voice synthesis comes from outside the GPS audio stream. Therefore, the Android\Settings\GPS volume settings never get triggered. The outcome for our head units is that the GPS talks over the music at the same time and at the same volume (fighting to be heard).

Just for your info I have a KLD S07 (universal 6.2inch model) / RK3188 / KitKat 4.4.4 / MCU MTCB-KLD2-V2.67 / 800x480 resolution. I use iGO Primo v9.6.7 in my GPS SDcard (it does not matter if it is installed internally or on the SD card).

As you requested I will send you a PM with the link.

Thanks again,

ggee :)

OK to answer my own question. Dashcommand doesn't appear to work and simply doesn't see the paired Bluetooth OBD2 controller. Seems like only the torque version in the OEM .apk works for whatever reason. Shame as I prefer the look of dashcommand but whatever works, its only a Camry.

Thanks for guidance. I decided to install poweramp (use it as main music player), deployed newest PVC and so far it looks promising. Problem with restarting mysic player always with first song on the list is gone.

I still need to test some various options, because DVR often not restarting (even with usbmnt command) after sleep (starting well from cold boot). I suspect it may be related somhow to that poor quality DVR camera sold with these headunits. (although if start of recording is successful it never unmounts). I plan to temporarly disable Daily Roads and see if there will be any issue with other early start/restart of services. I also noticed that poweramp toast not always restart whereas petrow's service always restart first without failure. I need more observation to draw conclusions.

So theres no app or tweak that lets an app take exclusive control of the audio that you know of?
[MTCB Android Head Units Q&A] agentdr8:
Yep. The headunit basically turns off the screen and any audio output, but it's basically powering everything else.

If you can believe it, these headunits were designed around using

just

the MTC apps, even though it has Play store support, and not everyone likes the included music and video apps. Audio switching between different sources (radio, android, bluetooth, aux, dvd, ipod, atv/dtv) is controlled by each individual MTC app, which signals the MCU to switch the physical audio output.

Depending on your use-case, XposedMTC might help. It comes with a few "wrapper" launchers called MyMusic, MyVideo, MyRadio, which basically send the needed AudioManager parameters to switch audio from one source to another, and utilizes your preferred music and video player apps set in the module's preferences. It's limited to just those 3 apps though.

I put it in the system/app folder and even used a tool app to set it on boot, and in the Odometer app itself I checked the "start on boot" option but still doesn't start.

Hi all, I have just installed my new KLD quad core 1024x600 in replacement of an S150. Almost everything ok, except SWC. The HU model is for Subaru legacy 2010, with previous S150 the SWC were OK, now with the RK 3188 they don't work. Subaru SWC is resistor type into the factory menu in CanBus the HU was set with the 5 option GM, I tried some other settings like Toyota and Kia but without success. The two wires connected should be OK (4 and 13 of Subaru 20-pin Receiver Wiring Harness) but I'm not sure about the presetting of CanBus (5 GM). So, can somebody suggest me something that can fix the problem? What' should be the correct setting for Subaru Legacy 2010? And can the HU manage the SWC1 and SWC2 commands from my car? I guess yes... Are the wires correctly connected from the Chinese factory cable?
