xposedMTC doesn't work

The XposedMTC doesn't work. I use Coudu 4.4.4. rooted firmware. The app doesn't start after the boot. After I started the app, the app doesn"t work.

I installed Xposed framework de.robv.android.xposed.installer_v33_36570c.apk and the newest app: com.dr8.xposedmtc_v164_8feb05.apk

I tried previous version of app, but they didn't work.

You have to activate the main xposed module after you install it and then reboot.
[MTCB Android Head Units Q&A] typos1:
I wasnt suggesting that you were lying or misleading anyone, just that your explanation was wrong and against the established knowledge of these units, although as I ve said, I want it to be right - I d love Viper to affect MTCmusic !

But my point was you have no actual evidence in code that its doing it, just that theres a change in sound when you turn the graphic display on or off and youre assuming its Viper doing it, although I have more confidence in what youre saying now I know youre a developer.

I ll re-install Viper later and see what happens.
[MTCB Android Head Units Q&A] devilsoft:
You need to install the xposed framework from xposed manager app, then you need to enable the XposedMTC module from Xposed Framework Manager -> Modules (check)
[MTCB Android Head Units Q&A] typos1:
Well if theres nothing in this thread theres no answer, although I m pretty sure someone bootlooped and got out of it once, the point is you are being way too over cautious, hardly anyone has got into bootloop, but literally hundreds of people have re-flashed with no problems.
[MTCB Android Head Units Q&A] devilsoft:
Well, my argument was not about the code. I was just discussing about the sound results using Viper FX. I forgot to say, that I was playing with Viper FX settings while MTC Music played in background, so I can see that Viper FX actually does the job, and it does. If I let the graphs (Visualizer) enabled, the Viper FX settings I change has no effect whatsoever. So that's what I mean when I say that the Viper FX works 100% with MTCMusic when Visualizer is off :)

I attachet a screenshot with the video advanced settings. There are no copyright issues enabled.

EDIT:

It seems that the video has a portion of a song in it, which is the reason why you cannot see it :(

This is what appears on my video, audio: Your video is blocked in some countries due to the presence of this song. Removing this song may unblock your video globally. Learn more
[MTCB Android Head Units Q&A] typos1:
You can easily bypass it with an add on for your browser like netvideohunter, videodownloader (this addon can download videos even if Youtube doesnt play them) etc, theres also an addon for Firefox that stops the blocks fro some countries on Youtube videos, I saw it no problem though, it normally says when the addon that stops the block is enabled. Cant think why the US would block Romanian Youtube.

Rom differences

I'm curious, since roms are interchangeable between HUs, what the differences are.

Is it basically the launcher/widgets that are unique to each? Maybe folks running a particular rom could reply to this post with the rom name/version and screen shot so we can know/see the differences.
[MTCB Android Head Units Q&A] wmccann2:
New unit

Hi all,

Just recevied my unit -

KLD-s7 (thought it also has 701 in name - not sure)

Details:

Dual core rockall 3066

1GB, 8GB internal

Ipod control

Digital TV (not HD though)

Dual USB inputs (max 32GB)

Dual micro SD (max 32GB)

Canbus module for Audi A4

External rear camera, front camera

DVD

Works with external HDD (as long as it is powered externally) - 320GB

MCU 2.3

Android 4.4.4

So far works well - some things are bit fiddly (e.g would like a bigger button for task switcher). Netflix etc works great

Far better than my Kenwood 9260BT - this radio was so sluggish it was annoying and while the voice control was good many buttons were not mapped e.g. in ipod next/previous worked but play/pause did not.

Issues:

1) Ipod control can't seem to cope with over 16GB :(

2) Canbus only does volume and channel up/down. - Extra buttons (telephone & R/T) on wheel are not recognised

3) Canbus increases volume by 1 click if I go over the "car" set speed warning, reduces by one click when I go below

4) Canbus - no other info available - assume this is due to

5) Canbus - had to connect reverse wire directly as canbus signal not working

6) Canbus - have to connect illumination wire directly as canbus signal not working.

7) Can't display the screen on the rear screens - only the DVD/Digital TV and a few other internal programs

8) Appears bass is missing from the line outs - sound can be a bit high.

Questions:

1) Has anyone got more info from the Canbus (steering wheel app does not do anything) with and Audi A4 B6 (2003)

2) Any way getting other apps to display on the rear screens - even if they must display on front screen as well?

3) Any way of "auto starting" apps e.g. spotify, Torque etc when radio is switched on - seems to work with some apps?

4) are there TMC and DAB adapters available for these radios?

5) Any way of getting ipod control to work with 160GB ipod?

6) On the back of the radio there is a socket marked Rear USB - I can't get this to work - anyone got any ideas

7) On the back of the radio there are 2 other sockets with no markint - "C" & "E" - anyone know what these are for?

8) Anyway of mixing the subwoofer output with the front line out ?

Any help in answering one or more of these would be great.

Thanks,

W.

I have Xposed framework de.robv.android.xposed.installer_v33_36570c.apk and the newest app: com.dr8.xposedmtc_v164_8feb05.apk

From where can I download the mentioned xposed manager app?
[MTCB Android Head Units Q&A] typos1:
Yeah and some of the icons, there may be some differences in code too, try them and see its easy to do use Titanium backup if you dont want to loose everything, there are plenty of screenshots on here already.
[MTCB Android Head Units Q&A] devilsoft:
If you installed xposed framework, there is a new icon in launcher (check the last page(s)) and click on that.
[MTCB Android Head Units Q&A] typos1:
Right, I see, that certainly does point to what youre saying being correct and it is good news ! Cant try it today too busy, but I ll have a go tomorrow. :)
[MTCB Android Head Units Q&A] Us-Marshal:
I have looked - and while there are lots of random shots it's difficult to keep track of what image is for what rom. Most images are posted to help with a specific issue and not just saying 'here is my rom'. I was simply suggesting consolidating and clarifying what rom is what.

I do have TBU installed and can sure install random roms - but that is one person gaining the experience. I was suggesting that it would be useful to document the differences so everyone can benefit from the shared knowledge.
[MTCB Android Head Units Q&A] typos1:
I ve posted screen shots myself and seen many posted by others and the visible differences we discussed in our previous posts.

Its so easy and quick you may as well flash one of the ROMs yourself if you want to evaluate any other differences - you could have flashed one in the time taken to write your post !!
[MTCB Android Head Units Q&A] Us-Marshal:
As I said, the purpose was for shared knowledge.
[MTCB Android Head Units Q&A] Palinkat:
Thanks a lot mate, would you consider adding this as a feature to MTCxposed?

Cheers
[MTCB Android Head Units Q&A] devilsoft:
it seems that its not romanian related, but it's because of the sound from backround :) Youtube now auto-detects the audio from background, and add copyright issues to the video, unless you choose to remove it from the video. Now i know, so in future, I will choose another background sound :)
[MTCB Android Head Units Q&A] Krisjan89:
1: have you tried playing with canbus type in factory settings?

3: yes you could try adding them in the install file ( search for it in tread)

8: update your rom to coudu kgl 4.4.4 from feburary 2015. The front and rear lineouts are not capped, they just suffer from poor software management in other versions

Has anyone had problems installing Sygic Navigation on a JY HU? It installed OK on my previous KD HU but doesn't seem to like my JY. After installation, you're taken to a Welcome screen with a large Start button at the bottom. It then stops on the screen with "Manage Maps" at the top. At the bottom of the screen it shows I have over 5 gb free. The timer thingy just spins and wont go any further :(
[MTCB Android Head Units Q&A] typos1:
Are you talking about the song your unit is playing ?
[MTCB Android Head Units Q&A] agentdr8:
The MTCMusic app outputs on the "sys" audio channel, which is the same as all other Android apps. Based on that, any software EQ should process the sound prior to it getting processed by the built-in amp's EQ (as controlled in the Settings->Amp). Whether or not there's a perceivable difference, I can't say as I've never used ViperFX on these HUs.

If you're in a bootloop, and don't have TWRP recovery installed, your only option is to flash another update.img from stock recovery.

Will do if it's possible.

Youtube scans uploaded videos for copyrighted music via some proprietary music fingerprinting methods and blocks them if it detects anything.
[MTCB Android Head Units Q&A] typos1:
Really ? I thought all the built in apps werent controlled by Android at all and that this was established long ago ? What about the radio app then ?

Glad I m wrong though, Viper did make a difference but I ve been using the built in app as I cant find any other one I like, so I m very pleased.

Tis a bit OTT of Google, I mean it was only a small piece of the track to demonstrate the difference in sound.
[MTCB Android Head Units Q&A] agentdr8:
Here are the audio output channel names that I've found in the code:

MTCRadio - fm

MTCMusic - sys

MTCMovie - sys

MTCAVIN - line

MTCIpod - ipod

MTCDVD - dvd

MTCATV/DTV - dtv

They all get processed through the built-in amp EQ, unless maybe if the pre-outs are used (I haven't verified this though so I could be wrong). But anything that sends sound via the "sys" av_channel should go through Android's audio routing.
[MTCB Android Head Units Q&A] typos1:
Great, I can use MTCmusic and Viper.

Is this something youve just found out, or have I mis-understood the way it works for months ? :(

Thanks for bringing it to my attention [MENTION=3744488]devilsoft[/MENTION]
[MTCB Android Head Units Q&A] agentdr8:
As far as I know, it's always been like this. I thought I had mentioned it in the past when I was researching the mode switching.
[MTCB Android Head Units Q&A] DRidilla:
I'd love if Waze could lower the radio to give alerts or if the radio volume was normalized with the android volume, because right now it is wayyyy louder. My assumption is because of the radio being seperate from the android stuff that it's hard to get them to co-exist well? Like spotify playing should kill the FM radio and vice versa.
[MTCB Android Head Units Q&A] agentdr8:
If you set Waze as the GPS app to monitor under Settings->GPS, and have it set to mix with a negative value, it should lower the volume when there are alerts/directions.

You'll also want to play with the audio settings for radio and sys in the Settings->Factory Settings to try and normalize/equalize them.

These headunits weren't designed to be used with media players that aren't MTCMusic/MTCMovie. Those particular apps have the means to switch to the "sys" (android) output when launched, and turn off the previous av_channel. All the current android media players available are only aware of one single output source, and that's android's audio routing, so they don't know to "turn off" other audio sources.

I think I could probably extend XposedMTC to include a service that watches for pre-defined media players (via a preference list) and if they are launched while the av_channel is anything other than "sys", exit that av_channel and activate the android audio. Now that I think about it, this would probably be a better implementation than the current My{Music,Videos,Radio} alternate activities.
[MTCB Android Head Units Q&A] Netconn:
Na, Waze don't work for some reason. It won't lower the radio / music volume. I switched back to Igo because of this. And Maps shuts off the music all together.

Hi to everyone, I have ordered this unit, but I really don't know how long it's gonna take to arrive here..

I have followed this thread for some time and I have to say it's pretty impressive. Thanks to everyone involved.

I'm a professional graphic designer and might be willing to contribute with modding the skin(s). I'm not purely a UI designer, but I have some serious experience with mobile UI's and stuff, so I could try to do at least something.

As I told, I don't have the unit yet... Could someone send me the decompiled app so I could take a look at it? Just send me a private message to deal about the transfer.
[MTCB Android Head Units Q&A] 1-2-Hak:
If you use apkmultitool to decompile and compile - options 9 and 11 (system apk) There is no resigning needed :)

When you pick option 11 choose No then Yes when prompted during compile.
[MTCB Android Head Units Q&A] kwalsh24:
Makes sense to me! Google+Android hmm makes perfect sense lol, Thanks for the little tutorial :)
[MTCB Android Head Units Q&A] 1-2-Hak:
Well the head unit is back in the car. Now wired up with 4 sony xplod speakers and a Vibe 8: 300W RMS sub.

This thing now rocks....

I was planning on getting the torque running and a front cam to do some drive recording but although they tested on the bench - dont want to work in the car - typical.

I have put a powered usb hub on the front so now I can charge my phone and plug in usb keys at will :)

I have had a lot of Car radio setups over they years but this one is now my best one yet.

(I dont need my loud switch to turn on anymore either..)
[MTCB Android Head Units Q&A] brownstein72:
How did you power your USB hub? mine takes 5V so I don't want to wire it straight up to a 12V acc.
[MTCB Android Head Units Q&A] 1-2-Hak:
Really easy. I have a cigarette lighter usb charger that runs at 2A. I just ran a usb male to male cable to the hub.

The hub has 5 ports on the front and 2 on the back. I mounted it so you can plug into the front 5 ports and the back ones go to my usb ODB2 adapter and the radio.
[MTCB Android Head Units Q&A] parazit26:
this is my advantage of using and arduino in my car. i have wired up all sw buttons to the arduino and connected it to my nexus 7 via bt so i have all signals and can map all buttons. Since Fiat has this box so called "blue & me" i can't get all buttons to work via a can bus adapter. Volume + - Next previous and mute are working. But i have more buttons such as escape, pick up calls, up and down....that would be such a pitty if i cant use them.

I read that there are two cables which are responsible to deliver the signals to the blue & me box. i could attach them to the radio/can-bus adapter, but don't if this will work or how to do it :(

Its a HuiFei unit, no one else has reported the clip problem since, so its up to you.
[MTCB Android Head Units Q&A] sciallo:
The way I understand it (correct me if I'm wrong) that arduino project senses resistance for SWC, the same as key1 key2 on these units. so whatever the arduino can do with a tablet the unit should be able to do as well, but also communicate with the MCU. Though I assume with the arduino you would be able to map buttons to more "things android" as there is a "limited" set of functions you can map buttons to. with the built in key1-key2 you'd be able to map MCU functions that you can't with the arduinno (unless you figure out how to trigger them programmatically, there should be a way).

As far as the box and can bus, is there is no way to get those to work through can bus adapter, it wouldn't work for either solution (I'm guessing?) BUT you should always be able to tap into the wires before canbus.... the SWC tend to always be resistive or voltage based because of the need for wires to go through a spring or brushes at the sterring wheel and only 2 wires are used in these configurations. I've red of people checking that with a meter and connecting their key1 and/or key2 at the steering column, before it goes into the canbus...

Edit:

A bit on how to check for resistive:

key1 and key2 allow for two separate sets of buttons, some cars use just 1, some cars (with more buttons) will use two. On resistive SWC you're sensing resistance (ohms) between a wire and ground, at the steering column it might be between two wires, in some case it's voltage but that would typically not be at the steering column if you disconnected it, it would still be resistance (I hope I'm making sense so far).

To check if that's the case it's simple, find the connector that attaches the SWC in your car, perhaps you can find schematics online to help with that. I would attach one probe of the meter to a ground point (anyhwere on the body of the car, you can check it's a good ground by setting it on volts DC and touching a 12v point (eg center of cigarette lighter).

Now set your meter on Ohms and attach the other probe to one of the wires coming from the SWC. Press one of the buttons and record the value, if no value try another wire, if no values are shown with any of the wires it might not be to ground and you'll have to start testing combinations of wires.

Once you see a value, you should see different values for each button you press that's your "key1" IFsome buttons don't work for example right side buttons register a value but the left side ones don't try another wire until you find the one that works with the other set of buttons, that's your "key2"

Just ordered this yesterday, http://www.aliexpress.com/item/Capa...Stereo-DVD-Video-Audio-Player/1517447202.html

I would like to root this unit. Is this what I should do?

1. Install Root Master v1.3.6, do not update to v2.1.1

2. Run Root Master then press Mulai Root

3. Press Root when see popup

4. Press Purple button when see another popup

5. Uninstall Root Master

Do I need to install RockChip for bootloader? I do not see a guide to unlock bootloader unless i miss looked.

Can only hear caller with line level audio outputs (not RCAs)

Hi all,

I thought I would mention that I blew up my internal amp. So I bought an external amp and connected up the amp to the RCA audio outputs.

Then I found out that the bluetooth wouldn't work. I confirmed it was due to the rca audio outputs, as I bought a new head unit and tried both the line out outputs as well as the rca outputs. Only the line level outputs would play the callers voice through the car speakers. The microphone was still working as I checked this with a caller.

Is there a way to get the mcu to play bluetooth phone calls through the rca outputs as well as line level outputs?
[MTCB Android Head Units Q&A] MMouse:
Sorry for the very late reply, I could not get to the IGO folder, everything was in the car, I noticed I did not have a backup upstrairs.

Any way, this should be the line : screen_xy="1280_800:864x555/600x800,1280_720:864x555/600x800,1024_600:864x555/600x800,960_540:960x499/540x888,854_480:854x442/480x816,800_480:800x442/480x762,480_320:480x295/320x455,400_240:400x225/240x385,320_240:320x221/240x301"

Your Data zip needs to have a reference to this.

Also I found a few other items that might help you, they are disabled for me though:

[android]

;fullscreen=1

;tablet=1

;has_physical_home_button=1

In any way, you need to make sure that the resolution you want to use in DATA.zip exists.

Then point the actual resolution, in this case 864x555 (so minus 45 on the horizontal lines) to make it show the buttons on the lower bar, so it takes the software buttons into account

In fact, I did a terrible mistake yesterday, I did a short circuit in my unit and now it is down :(

So, until I make it fixed, I will stop working on the any mods

There's an app called Tablet Talk. It's a software designed to be able to receive and send sms remotely from an android device as a tablet or an head unit by wifi with an android phone.

This app has a build-in call interface that looks like the android native one, and it allows to see the name and the picture of the caller.*

Maybe it will be suitable to what you want.

[MTCB Android Head Units Q&A] pakidermo5000:
No need for strange transfers. The app is pretty small.
[MTCB Android Head Units Q&A] agentdr8:
Well it really depends on where the audio is coming from. If you have an android media player in the background, it's up to it to determine what action(s) will take place when another android app (Waze in this case) tries to play audio. Poweramp has its own settings to handle the music when other apps try to take audio focus temporarily and permanently. MTCMusic has no such settings.

It also makes a difference if the nav app outputs sound on the proper audio stream; not all nav apps output directions/alerts on STREAM_NOTIFICATION. I haven't actually looked to see which stream(s) is/are being monitored by the GPS monitor.
[MTCB Android Head Units Q&A] patagonia1:
It would be an excelent adition! I usually end with radio and spotify/jetaudio mixing together :laugh:
