[Nexus 6P Q&A, Help & Troubleshooting] toadfist:
Got a new head unit, specifically so I could use AOA 2.0 / USB DAC with my Nexus 6P. Unfortunately, it seems that my new Kenwood DPX792BH has a specific incompatibility with the Nexus 6p? I called Kenwood about this, they didn't seem to care so far... Anyway, here are all the things I have done so far:

1) Tested my Nexus 6p with AOA 2.0 on friend's year old head unit, Kenwood KDC-X599. Sound and control via USB worked as intended.

2) Installed new DPX792BH. Nexus 6p charges over both front and back ports, but both devices wont talk at all. No warnings pop-ups or errors, just charging and nothing.

3) Tested my DPX792BH with multiple other phones. Iphone, Galaxy note 5, and Nexus 5x all work fine/as intended.

4) Tested my DPX792BH with Nexus 5x (USB-C) which also works fine/as intended.

5) Tested a different Nexus 6P. It has the exact same behavior as mine.

6) I have also tried multiple cable combinations... 3 different USB-C to USB-A cables. I used a USB-C adapter to micro USB, and that didn't work either.

Edit: Tried all possible combinations of having the Kenwood app installed or not. Had no affect on phones working or not working.

So at this point I am nearly certain that this is either a Nexus 6P bug, or a Kenwood Firmware bug, but I am not sure how to proceed.

Just to be clear here, I am only interested in this head unit if it plays digital audio via USB with my Nexus 6p. I am going to return the head unit if it will not. In this case, sound over AUX or BT are not acceptable solutions... I wish the 6P had apt-x, but it doesn't.

I guess what I am asking is, has anyone seen this and found a work around, or have any ideas? Should I be submitting a bug report somewhere?

I realize that someone will probably want to see some sort of logs, but I am not sure which ones... Let me know which ones to get and I will update this post. Thanks!

Edit: The response I got to this problem from Kenwood:

Final Edit: So no firmware update from Kenwood, I am running out of time to return this unit. I will be sending it back. I also wanted to add here, if anyone else is wondering, AOA 2.0 did not work with a Nexus 6P and this unit even when I installed CM13 nightly. I then tried with Android N dev preview 5, and had no love there. The OTA Android N final just hit and I have installed it. I will update here if it does work, but if it doesn't (as I expect it will not), I am sending the head unit back an I may forget to update.

I just bought an Android Radio from Pumpkin (Model RQ0264). So, I'm quite satisified with the device itself from technical point of view. The original radio app is also usable, but the user interface is a color mix and not really nice to see in my opinion. So I decided to change the skin because the radio app is used 95% of my time in the car and this is also the app which is visible at the start of the device.

Following improvements:

- The main information is now centered on the screen: Station name or frequence, Radio text and PTY information.

- Presets at the bottom

- Radio frequence search and selection at the top

This version is intented to be clean and not overloaded with useless features. So the modded version doesn't include the following features of the original app:

- No extra list for all stored programs (available in the original app right to the 6 round station buttons)

- No PTY list (Who is using this?)

- No circular frequence indicator, only the linear one. I don't see a reason to have double information.

This radio app should work on RK3188 models. To install this, you have to replace the original app. This is only possible on a rooted device or on a device with a modified custom ROM (e.g. Malaysk ROM).

For MTCB/MTCC devices there is a Bluetooth app from me in similar design available: MTCFlatBluetooth

Changes:

v1.00 (22.Aug 2016, stable, only MTCB/MTCC devices)

- works on both resolutions

v1.01 (20.Sep2016, MTCD, for test purposes)

- improved frequence bar

- seems to be working well so far, please report bugs because I don't own this kind of device

v1.02 (21.Sep2016, MTCB/MTCC, for test purposes)

- improved frequence bar

- stereo indicator added

- TP indicator (traffic program) added

- numberic input of frequences added (see screenshots)

- tested on 1024x600 device, needs to be tested on 800x480. I created one layout file for both resolutions to simplify further updates for all device types. You could see some differences in comparison to v1.00 - please check.
[MTCB Software Development] tipouce:
Hi.

First, sorry for my bad english ;)

Thanks for your apk. It works on my new MTCC (not installed yet) head unit.

It's the only one i found on XDA that works well. Others do crash the launcher

My model :

S07

MTCC-KLD6-V2.91

1024x600

I have only one issu, which is not really a problem, it's about the freqency bar : i show only the fm 65-90Mhz instead 875-107 regardless the setting of the headunit.

Best regards.
[MTCB Software Development] pathfinder78:
Thanks for your feedback. I found the issue in my apk file and uploaded it now. Could you please test the updated version "2016-08-17 MTCFlatRadio.apk", if the problem with the frequence bar is solved now?
[MTCB Software Development] tipouce:
Hi,

Good job. the frequency bar issu is solved as you can see in the video.

https://youtu.be/hQVzHPDVpmE

But maybe you could take a look at the scrolling text : for the long line of text, the restart of the scrolling is not natural and "it stings a bit the eyes" (sorry, that's a french expression = that's a bit annoying).

But apart this little issu, your app is very nice as it is.

Best regards.
[MTCB Software Development] pathfinder78:
Thanks for the video. It seems that the radio text is updated several times and if it is so, the text is starting from the beginning and break the smooth scrolling. The only solution I have is to remove the scrolling. If the radio text is too long, the text will be wrapped to an additional line now.
[MTCB Software Development] bdog720:
Hi [MENTION=7595091]pathfinder78[/MENTION]

Really like the look of it but I don't have a head unit with that resolution

Any chance you could make this for 800x600 resolution?
[MTCB Software Development] tipouce:
Hi pathfinder78,

Thanks for your job on the mod.

Now, all works good for me.

Best regards.
[MTCB Software Development] vettn:
Installed it last night. looks good, but all I get is static on all stations. I tried changing the frequency in the settings to both America 1 and 2 and nothing has changed.
[MTCB Software Development] pathfinder78:
What does it mean 'static on all stations'? Could you explain the problem more in detail, please? Is the frequency search not working (arrow button left and right) or can't you switch between different frequency bands?

Gesendet von meinem Mi-4c mit Tapatalk
[MTCB Software Development] pathfinder78:
Maybe on the next update I can also include the lower resolution. But it will take some time.

Gesendet von meinem Mi-4c mit Tapatalk
[MTCB Software Development] vettn:
no radio stations come in at all. just noise. as if there was no antenna attached to the radio. I can scan or manually select stations. I loaded the original radio app back and the stations are working again.
[MTCB Software Development] pathfinder78:
What kind of RK3188 device do you have? MTCB, MTCC or MTCD? If you have the last one, maybe the app is not working. Could you provide me your originally apk file or a link to a working ROM file of your device? I will have a look on it.

Gesendet von meinem Mi-4c mit Tapatalk
[MTCB Software Development] vettn:
it is the MTCD, with the last (august 10 I think) update from Joying. I'll try to get the original apk in a little while. or the rom is here here
[MTCB Software Development] psxsnake:
I would like to use your "radio skin" on my Pumpkin RQ0264, but i dont know the right path (is the 5.1.1 version)

thanks
[MTCB Software Development] typos1:
Can you guys post some links or pictures of your units and maybe links to any firmware you may have ? - It turns out that the MTCC units are actually MTCB headunits with renamed and updated MCUs meaning that the software is interchangeable.

Can a mod move this post to the MTCB/MTCC forums ?
[MTCB Software Development] halloj:
Installed it in Malaysk Ver. 3 MTCB 5.11. Looks really nice. Sounds good. Thank you.
[MTCB Software Development] pathfinder78:
Hi, please test the last version 2016-08-22. I added support for 800x480 resolution.
[MTCB Software Development] pathfinder78:
I extracted the Radio app from your ROM file and yepp, the radio app for MTCD models is not compatible with MTCB/MTCC models. I added this information to my description, but I can't update the layout of the radio app for MTCD models without to much time. Sorry to say this, but many thanks for your test and information that this is not working for your model.
[MTCB Software Development] pathfinder78:
You have 2 options:

- The easy one: Install Malaysk ROM for MTCB units http://xdaforums.com/android-auto/mtcb-software-development/rom-malaysk-roms-lollipop-5-1-1-mtcb-t3394209

- The other one: Modify the Original ROM from Pumkin and remove the original radio app inside the ROM. After that you can install your own radio app and also the original again, if needed. This way I have done because the Malaysk ROM was running slow on my device. If I have time, I will provide a instruction for this - but there are out there many descriptions how to modify a ROM and specially a RK3188 ROM.
[MTCB Software Development] psxsnake:
So I can't do on the fly :D with root explorer? hehe
[MTCB Software Development] pathfinder78:
If you are able to root your device, you can do this with root explorer and replace the stock apps. In my case, I was not successful to root my device. Some instructions said that you can root by typing password *#hct#root# (instead of 126) in your car settings and than use "KingRoot" app etc. - this was not working for me.
[MTCB Software Development] psxsnake:
I'm already rooted... thanks
[MTCB Software Development] psxsnake:
to root is right the istructions but the app is KINGO ROOT ;) you did same mistake of me at first time :)

The radio dont work on my, maybe i did something wrong

in /system/app/"radiofolder"/

renamed original in no_****.apk

remaned your in original name.apk

set 644

reboot

no app radio...

maybe i have to let only one apk in same folder?
[MTCB Software Development] pathfinder78:
Ok thanks for the information. I will try that on my device.

This procedure sounds strange for me. If you have really root access:

- Make a backup of the original radio app

- Deinstall the stock radio app (e.g. with this app https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp)

- Install my radio app via normal file explorer or apk installer

If you try to install my radio app without deinstalling the original app, the installation will fail with message "application not installed". This is because the original radio app has another signature than my radio app. To restore the original one, same procedure: first complete deinstallation (now the normal way via settings > apps > deinstall) and after that reinstallation of original app. For the complete installation you don't need to rename any folder or change permissions etc.
[MTCB Software Development] psxsnake:
[MENTION=7595091]pathfinder78[/MENTION] i did, the problem was becouse i let 2 apk inside same folder

work good thanks
[MTCB Software Development] bdog720:
Hey pathfinder

Tested out the 800x600 resolution version. Works great and looks amazing!

Thank you so much!
[MTCB Software Development] pathfinder78:
Could you please make a screenshot how it looks on your device? I would like to add this to the description of the app.

[MTCB Software Development] bdog720:
Hey [MENTION=7595091]pathfinder78[/MENTION]

So not sure how I got this mixed up but it seems the resolution is actually 800x480. Regardless it seems to fit perfectly on the screen (I've attached a screenshot here)
[MTCB Software Development] pathfinder78:
Thank you, looks cool with your background. And yes, I calculated with 800x480 - because your given resolution was strange :)

Hi

This is the best apk for the radio. Clear and nice.

I have one question.

Is it possible to change the Presets (with the name of the station) with a picture of the station?

I thougt i only have to change the picture of the icons, but i don´t find them in the apk.
[MTCB Software Development] Pedaaa:
I would really love to use this app.

Do you consider releasing a MTCD-version of it in future?
[MTCB Software Development] karmacop:
Can you give an ideas on what is involved in making this work with the MTCD radio app? I'd like to have a go as the stock app is pretty terrible!
[MTCB Software Development] ACSlater:
Great work! Finally all those stupid decisions the devs made are corrected. Now if someone would do the same to the even worse DAB radio app...
[MTCB Software Development] vch88:
Nice work. Very clean and useful.
[MTCB Software Development] Octalus:
Same situation here - I have a MTCD and it would be great if you can also optimize the app for this radio!
[MTCB Software Development] pathfinder78:
I created a package for MTCD devices now. Please test this and send me some feedback and screenshots. If it's not working, please keep in mind that I don't have this device. I will fix problems when I receive some feedback from you. Enjoy.
[MTCB Software Development] Pedaaa:
I am going to test it tomorrow morning.

Maybe a stupid question upfront:

How can i save my original radio app, in case yours wont work?!
[MTCB Software Development] pathfinder78:
I recommend APK Installer for backup your original apk (Manage apps -> Backup):

https://play.google.com/store/apps/details?id=com.apkinstaller.ApkInstaller&hl=com
[MTCB Software Development] -=Jeff=-:
I like it!!

I need to try this on my MTCD unit
[MTCB Software Development] -=Jeff=-:
So I installed this tonight.. I have a Joying UL-135 MTCD Unit. I was running Malaysk V6, but Had to install V4 to get the radio app to install. For some reason in V6 I was unable to install any radio apk. this one, OEM, any.

I REALLY like the clear look and I can see my wallpaper. A direct tune would be great as I find the seek/search buttons are annoying when trying to tune a weaker station. but overall I like it.. I had to uninstall the radio APK, then install yours.. worked fine. I will get some pictures if you would like
[MTCB Software Development] pathfinder78:
Yes, please provide me a picture please. I would like to see, if anything is in place as expected. For the direct tune - I prefer to tap directly into the freqencebar and slide the indicator to the right frequence. However, I have not the right idea until now, where to place the button for the numberic input. I will notice this request for further updates.
[MTCB Software Development] Pedaaa:
Hello, i also tried to install your app on my MTCD, but i wasn´t able to.

It simply does not install.

I uninstalled the original app, and i also tried to delete it complete from the system/radio folder.

But it just won´t install.

Maybe i have some different MTCDradio version, thats not compatible??

i have attached my original app and also a picture of my HU-version

Edit:

i don´t have Malaysk ROM installed. I just rooted with Kingoroot
[MTCB Software Development] -=Jeff=-:
I will get some pictures for you soon. What if you moved the FM and AM buttons up on the screen and added a button below AM for 'Direct'. I too used the bar at the top to tune in a station, but my fingers are not as accurate as I would have hoped. I know if I hold the arrows down I can step it, but there seems to be a short time that if I am not fast enough it will go back to 'seek' for the next station.
[MTCB Software Development] pathfinder78:
I checked your apk file. It's exactly the MTCD app which I modified - so it should be compatible with your HU. I also doesn't have MalayskROM installed.

The installation itself should run in any case, if the app is compatible with your device or not, e.g. for test purposes I installed the app on my mobile phone - there is no detection for compatibility.

So I think, the old app isn't deinstalled properly before. Because the installer shows "not installed", if the signature of the previous apk is not the same like the actual apk which you want to install. For whatever reasons your system still knows the old app. Maybe you find an explanation and some ideas for complete uninstall here: http://android.stackexchange.com/questions/92025/how-to-completely-uninstall-an-app-on-android-lollipop. See point 3 and try to uninstall via adb - I would suggest.
[MTCB Software Development] karmacop:
Unfortunately I seem to be having he same issue on my MTCD unit. I am, running Malaysk's ROM and get the app not installed message. I froze the previous version of the Radio App with titanium before i tried the install, are there any other radio components that need to be frozen/removed?
[MTCB Software Development] Pedaaa:
Got it to work somehow. I tried like 50 ways to uninstall...

After re-installing the original radio app with the standard apk installer, i was able to see the app in the apk-installer also.

Once uninstalling from there, it seemed to be removed completely.

Then installation of the new app was possible.

It looks great.

The only issue i could find:

The app is not showing an radio station name.. I only see the frequency and "fm1", but no name..
[MTCB Software Development] dongali:
Got it to work on stock Joying mid August rom rooted with Kingoroot apk.

Attempting to install the MTCFlatRadio apk on top of the radio didn't work for me; here's what I did.

1. Removed stock radio app with ES File Exporer Pro

2. Reboot system by holding power button until LEDs on unit flashes 3x then let go

3. Install MTCFlatRadio.apk with stock app called APK Installer- this will fail

4. Install the apk a second time and it should go through successfully
[MTCB Software Development] -=Jeff=-:
Picture (MTCD)

I will get a couple screen shots too

Oh another useful button would be one to access the EQ..

Attached are a Screen Capture and then a photoshopped Capture showing an idea for the EQ and Direct buttons..

Am i the only one, who has non-working radiostation-names on MTCD???
[MTCB Software Development] pathfinder78:
Hi Pedaaa, was the station names working with the original app that you send me yesterday?

Gesendet von meinem Mi-4c mit Tapatalk
[MTCB Software Development] Pedaaa:
Yes, worked fine.

Maybe i have uninstalled too much of it?! ;)
[MTCB Software Development] Octalus:
Names are working on my side with a mtcd unit. The Radio looks great with a dark background! Thanks alot :)

Btw with dark live wallpaper even better!
[MTCB Software Development] Pedaaa:
Oh, it really seems, that i have uninstalled too much. I now again tried it with the original radio app, which also doesnt find any names anymore.

I also deleted one app that was called com.android.radio or similar... I think this is the issue...

Could please someone check, if this app is still active somewere in the background?? Is it possible that someone could provide me the files required for this program?!

Many thanks!!!
[MTCB Software Development] pathfinder78:
I can give you only 1 suggestion: Did you uninstalled other packages starting with "MTC..." or "com.microntek..."? The Radio app itself is called "MTCRadio4" or "com.microntek.radio". Only this app needs to be deinstalled, then reboot and install the new radio app. If you deinstalled other packages, reinstall all of these.
[MTCB Software Development] Pedaaa:
Yes, exactly it was "com.microntek.radio"

First i uninstalled the radio app, but then this com.microntek.radio was still there. So i also uninstalled this one. Nothing else...

Very strange
[MTCB Software Development] psxsnake:
Is better you reinstall the firmware without wipe... Should restore app deleted
[MTCB Software Development] Pedaaa:
Thanks to everbody!

I found a workaround. I enabled/disabled RDS in the factory settings a few times. Now it works again :) i have no idea why, but it does not matter. Now it works :)
[MTCB Software Development] pathfinder78:
Hi Jeff. I added the numberic input in new v1.02 for MTCB. You asked for it for a MTCD unit and I tried to implement this there too. But the original apk file I have, doesn't have this numberic input. Could you please provide me your original apk file which had this numberic keys? Thanks. Another question about your screenshot. Do you have a modified dpi-value at your device, because all ui elements are smaller than expected?
[MTCB Software Development] -=Jeff=-:
I might have a modified DPI, I know I messed with that at one point, but I reflashed the V4 the other night and did not change that. I don't think the MTCD had the direct tune, but I will find the OEM APK and send it

Any chance to add the EQ button?
[MTCB Software Development] -=Jeff=-:
Here are pictures of MTCD 1.01. I don't see anywhere that I changed resolution for the radio. I also attached a shot of my home screen for resolution reference

Looking at the info from the Malaysk Post, I don't think the MTCD has Direct Access.. if it cannot be done not a big deal, but the EQ Access would be nice
[MTCB Software Development] Pedaaa:
Hi,

here are screenshots from my MTCD 1024X600 unit.

My icons look a bit bigger than on Jeffs unit.

regarding the EQ button:

would be nice, but i won´t use it too much anyhow, as i have a good setting and usually don´t change it.

But if you add this feature, you could place it on the left side above the AM FM buttons. Then it would have a nice symetrical look, with 3 buttons on each side.
[MTCB Software Development] -=Jeff=-:
I have no idea why my buttons are smaller.. They are still a good size to use, but that is weird
[MTCB Software Development] karmacop:
I got this working on my MTCD unit in the end! This does look much better than the standard radio app, however it still doesnt display the RDS data properly. Is this something to do with how the RDS data is provided to the app via the MCU do we think?
[MTCB Software Development] KMA_is_here:
Any ideas why I wouldn't be able to install the MTCD version of this apk on my MTCD HU? I have Unknown Sources enabled. I installed MTCD Tools just a few minutes before without issue.

Thanks!
[MTCB Software Development] -=Jeff=-:
Stock ROM or?
[MTCB Software Development] KMA_is_here:
Yeah, latest stock ROM for Volsmart HU.

If I select the apk it says it can not open it. If i try to install it using the installer app, it churns on it and just returns "not installed". I downloaded it multiple ways and put it in several folders on internal and external storage.
[MTCB Software Development] sslt:
I like this version. Can I download it?
