Question on closing apps/ help please.

I've searched the forums for a week and I've found things that are close but, this may be specific...
I have assigned my upper right button (the IE button) to do "Ok/Close" but, it never actually stops the program from running in memory. I've installed Magicbutton and that works for pressing the 'X'. I also installed "Smartkeys" and that works for pressing the 'X'. I trying not to use the touchscreen as much as possible. Does anyone know a way to do this have a button mapped where it actually stops the app from running in memory when pressed.
Thanks. :?:

smartskey does this, edit the .ini file :wink:

VJOkButt can also be used as a simple task closer.
smartskey is a great app though, much more versatility.
V

...'oxios closeapss' closes all programs, except the one currently in use, with only one button which you can easily assign to ie button...

Button, EditText and context menu not correcty drawn

Hi everyone,
Discovering Android development (and I love it), I stumbled across a little problem (that actually is very annoying).
When I run my little application on my cellphone (Android 2.1 update 1, Samsung GT-I5500, aka Galaxy 5), the views are drawn oddly. The left and right borders are drawn lower than the central part. This bug does not appear in an emulator. A picture is worth a thousand words...
A Button or an EditText should be drawn like this:
(Well, there would be an image here if I had been allowed to put one...)
Code:
__________
/ \
| |
\__________/
However, on my phone and for my app, it is drawn like this:
(Same remark)
Code:
______
_| |_
/ \
| ______ |
\_| |_/
Other applications (such as text messages, emails) do no seem to suffer this bug, so it has to come from me. This happens in the two activities I have (a ListActivity and an Activity), and even in AlertDialogs. What could I have done wrong ? Here's a sample activity layout.
Code:
Duh, I can't even put my XML...
Anybody has an idea ? This bug is quite... disappointing.

Actually the solution was pretty simple.
I only had to specify the minimum and target sdk versions in the AndroidManifest.

Tesla style headunit steering wheel key mod

Hi everyone,
I recently caved and bought one of the tesla style PX6 headunits from ali-express.
While the unit seems nice, it is unfortunately NOT an MTC head unit and so the mods that I had for my previous headunits do not work-- including the various steering wheel key mods out there.
As a result I started working on my own and have made quite a bit of progress, but I just need some help getting to the finish line.
Problem: factory steering wheel control app only allows for very limited actions in response to key presses.
Required end result: a user-customizable method of capturing steering wheel key presses and translating them into actions in android.
Current process in factory system: (fairly similar to the MTC headunits)
Key pressed on steering wheel ---> resistance value changes>>>MCU picks up this value and sends serial data to tablet--->App named "Eventcenter.apk" (com.szchoiceway.eventcenter) ---->protected method called startprocessCmdThread (runs on a loop and waits for serial data)----->private processCmd which then reads the serial data and determines (amongst other things) if it is a steering wheel command event---->private onCmdWheelEvent method which puts the byte data in an intent with action "com.choiceway.eventcenter.EventUtils.STEER_WHEEL_INFOR"
in the extras "EventUtils.STEER_WHEEL_INFOR_WPARAM" and "EventUtils.STEER_WHEEL_INFOR_LARAM"
where LPARAM is the actual byte data and wparam is either 4 or 3 (likely keydown vs key up event)
It then broadcasts this intent with permission: com.szchoiceway.permission.broadcast
This intent is picked up by the relevant "choiceway" app like for example the navisettings app which registers a receiver for this intent when you're in the steering wheel study activity and assigns the steering wheel key to one of very limited, pre-defined actions.
While listening for this intent would have been ideal to be able to assign your own actions to steering wheel key presses, unfortunately, the presence of a declared permission makes it impossible to do so without declaring this same permission in your app manifest. And since android 5.0, two apps cannot declare the same permission in their manifest unless they share the same signature.
As a result, in the process above the only solution i can see is either
1) we modify the relevant system apps to NOT require that permission when broadcasting an intent
or
2) create an xposed (or magisk?) module which hooks into the method calls above to capture the direct byte data being put into the intent extras and broadcast it's own intent/perform our desired system actions.
or
3) something else I haven't thought of
I have been trying to do this but have not been able to compile/sign any of the above mentioned apps after making my modifications.
I know xposed modules can do what i'm looking for but since this tablet runs android 9.0, it would have to use edxposed which i'm not as familiar with. Does anyone know if using edxposed is capable of hooking into the above method calls?
Alternatively can magisk modules hook into this method? I've never written a magisk module before so i'm not sure what the capabilities are.
Are there any other solutions you guys can think off in this process to getting this working?
thanks!

So far I've been using tasker Logcat to listen for the 'iCan key' events. I have been able to toggle play/pause on mute and my now useless onstar button opens google assistant in Headunit Reloaded. I would like to re-map the source/mode button to NOT switch to the FM radio since I never use it. I didn't even think to look at the eventcenter apk, have you had any further luck in the last year?

How to access Engineering Mode for AC8227L

I am brand new to the Head Unit world and have been on a VERY steep learning curve (sadly begun AFTER I purchased a unit #lessonlearned).
I bought on ebay an aftermarket chinese Android head unit and have been pouring over your website (THANK YOU for existing btw) looking for answers to all sorts of questions.
I have found most of what I was looking for between resources here and on Youtube, however, the one that I still need help with is figuring out how to access "Engineering Mode" from my menu. Most videos show it under the Factory Settings menu, but my menu is extremely limited compared to what I've seen on other units.
I've seen tons of videos of people with units very similar to mine, but with different interfaces.
I'm attaching my specs, a screenshot of my Factory settings, and one of the Factory Settings I've seen on other units.
Is anyone familiar with my settings and know of a hidden secret way of accessing the Engineering Mode??
Specifically, I want to figure out how to raise the external microphone volume which is currently so low that it might as well not be there.
I've emailed the seller for assistance, but so far his responses have been one step above useless so I'm not holding out hope that that will change any time soon.
Please let me know if I need to post additional information. Like I said, I'm new to this and don't know what I don't know.
Thank you in advance for your help. I truly appreciate everyone sharing their knowledge so generously.

Engineering mode is activated/accessed with pin code just like entering in factory settings, I don't know what pin is but you should serch for thread about 8227l pin codes on this forum. There are all codes and pins.

Thank you but when I enter my code on Factory settings it takes me to a limited menu, not like the one I've seen in other videos. It looks like the chip is the same, but the interface is different. I was hoping someone here had the same interface and knew how to access Engineering mode.

It is accessed by numeric pad (same as would for factory settings, but only entering specific code in number pad).
Code is 7788 so you must enter it in numeric pad in order to access directly to engineering mode.
Also, there are other codes accessed with numeric pad directly :
Code: 0 - Opens MCU update window (com.ts.can.CanMcuUpdateActivity)

Sadly, these codes work for the units I've seen in videos, but not with my interface.
I've added a video (second video) of the menu I have under factory settings.
None of the other codes I tried worked either (8888, 8877).
The original interface didn't even have the full standard android menu. No access to Apps or Build number for example, but I was able to get around that by installing Agama where those menu options are accessible. Which makes me suspect that Engineering mode menu is in the system. I just can't figure out how to access it from my interface.
With access to build number through Agama I was able to activate Developer mode but I didn't find what I needed there either.
Any ideas?

There are codes for your unit, you must find correct ones.
Try searching the net and youtube for it, enter model of your unit and search for pin codes

Thank you. I've searched but I haven't found any which is why I was hoping someone here had my same unit/interface and could help me.

1234 is for factory setings as I saw in video you posted, developer mode should be 7890+current hour (if now is 08:12 you input like 789008->which 08 is current hour)
In factory settings you can adjsut almost everything but developer mode serves as debugging there is no much to do there. Advanced mode is 123456, there are system settings regarding all configuration of all functions.
This codes are specific for TS10-TS18 units. What unit do you have , provide some info of device from car settings / about device menu.

The code 7890+hour didn't work on my unit, however messing around in the Car Launcher FREE settings, I found an icon for Car Settings (different from the one under factory settings). In there, I found 3 sub menus. Under the "other" menu, I found Engineer mode!!! I forgot to take a picture, but I this is a screenshot from a youtube video to showing the same menu options I see.
Once there, you scroll over to Hardware testing and then Audio. That's where you find ALL the audio levels you need. I'm still playing around with it as I haven't gotten the mic to the level I want, but at least I'm one step closer.
I've also seen other threads where folks have had better success after disabling the front facing mic.
I don't know if I have the guts to open it up and cut the connections, but I've done crazier things so ... we'll see.
THANK YOU everyone for your help. I hope my post can help anybody after me looking for a same info.

So you have JCAC system version from 2019 as I saw in image, that changes a few things... like PIN codes.
Will find correct ones for your system.
PINS FOR ANDROID
Try with these.
Play arround , enter each one and see what PIN activaes what menu. Eventually you will find correct one.

What is AppSwitcher?​
AppSwitcher enhances your steering wheel key to switch between apps.
Hereby you can select which apps should be offered and you can choose stock apps (e.g. the radio app) and 3rd party apps like your favorite mp3 or DAB player. You can switch between media and navigation app by only one key press.
Additionally AppSwitcher offers a lot of options:
- start the last used media app after boot and after sleep automatically.
- long button press to cancel (if dialog is shown) or to jump to home screen.
- reactivate accessibility service of Automate and start initial Automate Flow to realize your own automations
- enable/disable DuraSpeed to prevent the head unit from killing your apps
- change system property to make Android status bar visible (work as on other Android devices)
- automatic screen dimming based on sunset / sunrise information
- allows to start the (Junsun) equalizer app
- supports SWC key "mode" even if CAN box is in place (if modded MainUI gets used)
- ...

How it works​
AppSwitcher has two options to register for a SWC key. A basic understandinghow it works will help you to do the initial setup of AppSwitcher.
Option 1 - GPS​
The head units main app (MainUI) writes by default a log message on each key press. AppSwitcher can listen to the Android log and react on a log message.
This will not overwrite the standard behavior of the original key function but we can configure a SWC key and assigned it to "open navigation app". With a special app (AppSwitcherStarter) set as navigation app there is no need to modify system files or system apps.
This will only work if
a) a dedicated SWC key to start the navigation app is present. If no CAN box is used every SWC key can be configured
b) a dedicated SWC key to switch between apps (mode button) is present AND the radio app is not used/required
Option 2 - MainUI​
Replacing the head units main app (MainUI) with a modded version.
In this version, the SWC mode key is disabled so that its functionality can be overridden (replaced) by AppSwitcher.
Additionally the modded version starts AppSwitcher after boot / sleep and sends a broadcast on each key press. This allows AppSwitcher to register for the broadcasts to receive a trigger. Other apps (e.g. Automate) can also register for these broadcasts.
This will only work if
a) a modded version of MainUI is available
b) you are not afraid of replacing a system app and know how to flash a firmware in case of problems. You're replacing the system app at your own risk.

Installation​
Option 1 - GPS​
Please read previous post to check if this is the best installation type for you.
Spoiler
- Install AppSwitcher AND AppSwitcherStarter.
- Enable automatic start of navigation app in factory settings
and let your device reboot.
Please be aware that changing factory settings will reset some settings on your device like equalizer and radio station presets. This is not an issue of AppSwitcher(Starter).
- Open AppSwitcher and select your navigation and media apps. Additionally activate the log listener:
- Set 'AppSwitcher Starter' as navigation app:
Don't set AppSwitcher itself as navigation app.
- Configure one button of steering wheel to start navigation app (if not already done)
With this setup the head unit will start AppSwitcherStarter after each reboot/sleep whereby AppSwitcherStarter will start the service of AppSwitcher.
Pressing the SWC navigation key will also start AppSwitcherStarter but this will have no effect if the service is already running. Nevertheless the AppSwitcher service will recognize the log entry and can present the AppSwitcher dialog.
The log entry can vary from head unit to head unit so it may be required to adjust the log listener settings https://forum.xda-developers.com/t/...-devices-incl-autostart.4593865/post-88620913
​Option 2 - MainUI​
Please read previous post to check if this is the best installation type for you.
You choose this way of installation at your own risk. It may lead to a bootloop and you should be familiar how to flash a firmware to restore your device in case of problems.
Spoiler
- First you need to check if a suitable modded version of MainUI is available for your device.
You can find a list of modded versions here: https://forum.xda-developers.com/t/...-devices-incl-autostart.4593865/post-88620949
- Download the modded MainUI version, place it in the "Download" folder on the device and rename it to MainUI.apk
- Install MainUiUpdater and perform the replacement of MainUI system application. If the device freezes after the update simply use the reset hole to force a reboot.
- Install AppSwitcher
- Open AppSwitcher and select your navigation and media apps.
Ensure the log listener is disabled.
- Reboot your device. E.g. by using the Reboot.apk from here: https://forum.xda-developers.com/t/...r-aux-bt-music-carinfo-from-launcher.4237797/

Adjust the log listener​
Installation type "Option 1 - GPS" may require to adjust the log listener settings. They are pre-configured for systems without CAN box and a SWC key assigned to the GPS function (see Installation instruction on previous posts).
First you have to identify which log entries get written as soon as you press the SWC key. I suggest to use "Logcat Reader" from Google Playstore to identify usable log messages.
The log listener settings​
Log tag: Tag of the log entry. On most systems this is "MainUI".
Short button press log entry: If this log entry occurs AppSwitcher will show the dialog or jump to the next app.
This is the most important entry.
If you get a set of log entries as soon as you push and release a SWC key "Short button press log entry" should be set to the log message which gets written as soon as you release the key after a short amount of time.
Optional:
On button press log entry: This log message gets written as soon as you push down the SWC key. AppSwitcher will stop the countdown as soon as this message gets detected. This allows to set a very short countdown time.
Long button press log entry: If you hold down the button you can cancel the AppSwitcher dialog or jump to the home screen / launcher if the dialog is currently not visible.
The log entries need not to contain the whole message. It's sufficient to enter a substring if this is unique and not part of other log messages.

Modded MainUI​
For MTK825X​
MainUI_825X_1.3.apk​Version 1.3 from 8259P_军灿UI02v1280x720-国外_v81_20230427
Changelog
23/6/18
- Allow remap of SWC keys even if CAN box is in place
For 8667​To bring this version on the same level as 825X I need your testing support!
MainUI_8667_1.1.apk​Version 1.1 from 8667Q军灿UI02-国外-1280x720_v28_20230302.zip

Remap SWC keys​
If a CAN box is in place Junsun devices doesn't allow to remap SWC keys and assign other functions to it. But if you install a modded MainUI it is possible to define a config file with a mapping according to your needs.
The mapping file must be called "keyMapping.ini" and must be stored on the top level of the memory next to the "Download" folder.
The file is a simple text file containing key code mappings:
Code:
[from value 1]:[to value 2]
[from value 2]:[to value 1]
[from value 3]:[to value 4]
This is an example to swap the volume keys:
Code:
19:20
20:19
The most used key codes:
Mode = 10
Vol + = 19
Vol - = 20
next track = 44
prev track = 45

Sure. You can help to let the magic happen:

If you want to test the SWC key remapping via config file, let me know...

I can install MainUI on my unit (8667L), I need to know if the 8667L version is compatible or only for 8667. If it is compatible, is key mapping available for this version?

Could you please let me know which firmware you have currently installed by providing a link to the firmware zip file?
Key mapping can be made available but I need you to test because I don't have a 8667(L) unit.

Unfortunately I can't extract the firmware with the same tools I use for 8867 and 825X.
Could you please install MainUiUpdater and perform replacement without a MainUI.apk in Download folder? This should create a backup of your MainUI.apk file you can share here.

Hello TorstenH, I have a Junsun 8667Q and I would like to reassign the steering wheel keys, I have a 2019 kia Sportage with CAN, does your MAINUI work for my radio?
The VOICE button opens the google search for me and I would like it to open the google assistant.
Thank you so much
