G'day all. I'm trying to get this working on my 2021 Toyota Hilux factory head unit and Samsung S21+ Exynos running Android 11 but it seems like it's not going to happen. I have Torque Pro installed and connecting to my obd2 adapter and displaying data fine in the Torque app. I've tried both the a and b versions of the obd2aa app from the B3IT site. AA works fine for me normally.

I can't do option 1 because apparently the play store version of the app isn't compatible with my device.

Going through option 2 everything seems fine until step 7. I connect to the car, I'm prompted to choose obd2aa as the default app and I do that no problem. But then the phone never actually connects to the car. I've tried 3 different cables including an OEM Samsung data cable. They all work fine normally with AA, but when I try to use them with this process I either get notification straight away: "can't connect - try a different cable", or it just sits at "connecting" forever but never connects. AA never appears as an option on my head unit.

I'm not sure what step 7 actually means? Which tabs are we referring to in step 7? I assume it would be obvious if I could get that far?

Any suggestions, or is it a no-go for me?

Thanks very much.

Just for future reference, on my device (S21+ Android 11) you have to access Android Auto via the main Settings menu and Advanced Features. There's no Android Auto app as such on my device. To activate developer mode you have to scroll all the way to the bottom of the AA settings and tap the version number heaps of times until the developer prompt comes up.

Edit: clarification

So guys, none has been able to find a solution for this? I have a s20 samsung, android 11 and paid 3.6b version. When select obd2aa as default, screen flickers once or twice and that's all. Next is a message on hud saying unable to check whether my pone supports android auto. I'm still hoping Emil will help us sort this out, as this is a real deal breaker for me.

Cheers from Romania

Guys, until few days ago, i had no problem with this app. But today, suddenly i can't even see the OBD2AA icon within android auto program list. If I clear all the data for android auto app on the phone, then after first initialzation i get the OBD2AA icon, but as soon the phone is restarted it is gone.

So, could it be that google somehow prevent 3rd part apps from showin in that program list?

Same for me and solution fixed it as well. So anytime we restart the phone we have to clear and reconfigure AA.

Maybe we sold try with different app name? But I think it all has to be compiled with different name. Do we have a volunteer 😁

I'm having the same problem, I uninstalled AA and reinstalled but now I don't have the ability to open the Android auto app on my phone to start the head unit server, I was able to access it through a system setting but now obd2aa won't show up on my head unit no matter what I do.

I tested the modification of the name we can see the application in Android Auto but impossible to make it work whether it is directly from the application or from Android Auto. Émile must rewrite the application with the new SDK

    App Requirement
    • Torque Pro
    • OBD2 Reader
    • Android Auto compatible headunit or at least a copy of the Headunit Reloaded App (see signature).


    This app will have limited functionality if you are using Android Auto on a your phone, the only functions you will be able to use is to see are notification about the speed cameras and street card!
    Gauges and torque data will NOT work!

    Previous XDA purchases can be reclaimed here: https://www.b3itlabs.com/download.php

    How to purchase:
    1. Visit: https://www.b3itlabs.com/prod.php?id=2

    Instructions on how to get it running:

    Option 1 - Will work on any phone & car/headunit combination, however the following features won't: - AutoPlay Music, 6 Tap limit remover, DPI change

    1. After installing the app from XDA Labs, sign up for beta testing here: https://play.google.com/apps/testing/uk.co.boconi.emil.obd2aa and update the app
    2. Once app is updated, make sure you disable auto-update in PlayStore then please uninstall it and reinstall it from XDA Labs.
    3. With your screen unlocked, plug in the phone to the car, when prompted which app to use make sure you select "Android Auto"


    Option 2 - Might NOT work on some device combination (for sure it won't work on Xiaomi phones), but if this method works all functions of the app are available
    1. Install
    2. Make sure you do not have any other 3rd party app Android Auto app installed.
    3. Open the app and hopefully it will be quite self explanatory on how to set it up (choose colours, set gauge number, etc)
    4. Open Android Auto (on the phone), go to About, tap the "About Android Auto" header 10 times, once you are a developer from the 3 dotted right corner menu select "Start Headunit Server" (ROOT users can skip this step!)
    5. Close Android Auto
    6. MAKE SURE YOUR SCREEN IS UNLOCKED and connect to the car, when prompted which app to use select "OBD2AA" and always (this needs to be done one time only) - If you are a HUR user select Android Auto and always! (If you do not see the prompt to chose, please go to settings -> apps -> all apps -> Google Play Services -> Clear Defaults and then try again)
    7. Select the last tab on the right, by pressing it again you should see an app selector and choose OBD2AA
    8. Give it a bit of time to start pulling the data from Torque.

    Important notes

    Version 3.0 releases 05/07/2018

    • Compatibility fix for AA 3.0 and above.
    • Added option for overriding 6 tap limits
    • Added option for Bluetooth Audio output.
    Important notes

    Thanks to @slash_m_a_x for the support offered on this.

    - Some users have reported choppy audio when using the app, this will mainly be due to the speed of the phone, the buffer on the car/headunit and other factors which are out of my control, if that is the case and you cannot use the app please feel free to contact me for a refund.
    - Bluetooth Audio output might not work on all devices, it does depend how the car/headunit handles the Bluetooth. There will be devices which completely disable A2DP/Bluetooth capabilities of the car when Android Auto is running. In this case all the sound will be heard from the phone speaker rather then the car speakers.
    - Tap limit will be disabled only for cars/headunits which are equipped with a GPS.
    - In rare cases it can happen that after unplugging the phone from the headunit you will see a message which says that you are still connected to Android Auto, simply Force Stop the Google Play Services.
    - You always need to make sure that Headunit Server is running on the phone (unless you have root), if the icon bothers you simply hide it.

    How to use it?
    Open app and select each PID you want to display on your screen, adjust the number or gauges you want to see adjust the preference for each PID. If you want to use custom background/needle and interested on how to, please read HERE

    Locking Pid values
    On some PID's Torque reports wrong min/max values, by default if while using the application a reported value is higher/lower than the initially reported range, the app will adjust the range to the new values. However in some cases this is not desired and you will like to specify manually what is the min and max value for the give PID. In this case, simple edit the minimum/maximum for the pid and they will become locked, meaning the app won't make any adjustments.
    By editing, it means you have to change the min or max value, the lock is triggered by the first keypress on this input fields.
    The lock will be automatically removed when you select a different PID for the same gauge.

    Preferences menu
    • Alternative pulling - Only enable this option if you have difficulties getting gauges updated, it uses an old deprecated method of obtaining data so should not really be used.
    • Enable debugging - Only enable it if you have problems with the app and I requested you to collect a bug report, otherwise it will spam the logs for no reason.
    • Automatically start Torque on Android Auto - Nothing to explain here :)
    • Launch FartKontrol on start - launches a Danish Speed Camera app (useless outside Denmark)
    • Custom Background (any background you will like to use instead of the black color)
    • Demo - When enabled random data is generated for the PID's just to see how things will look (in case you do not have an OBD2 adapter), so don't enable it.
    • Pid Alarms section. You can set up a low level fuel warning (displayed as a heads up notification) and a notification when the engine is warmed up. There a several PID options for both of this, pretty self explanatory.

    TPMS Settings
    - You set up the 4 PID's for TPMS, this will be used to display the tyre pressure values on the TPMS screen inside Android Auto

    Speed Camera
    • Show current street card - Displays information about current street (name and speed limit if know). This information is updated once in 5 seconds and at a minimum distance of 200 meters so it's not 100% accurate it's more for general information.
    • Enable speed camera warnings - This will enable the app to display speed camera warning when driving, like any app which does this it relies on a database, which means it does NOT guarantee that it will warn you of all the cameras, and it might also produce false warnings. All options are pretty self explanatory.

    Export & Import
    - Allows you to export your current app configuration file which can later be imported (grate way of saving time of re-doing everything) after a clean install or so. The format use for Export & Import is JSON so if you want you can manually edit/adjust the values. Please see following post for more details about the sturcture/value/meanings


    Permissions
    • Read notification permission - Only required so the app can read the notifications from CamSam and display them on AA scren
    • Locations - Only required if you want the app to overwrite the day/night theme based on sunset/sunrise
    • Storage - Only needed if you want to use your personal image as a background and/or planning to import/export settings

    Can I create my own layout for the gauges?
    - Yes, see instructions below:

    Here is an example of the XML structure required, once you created the XML please send it over by email to [email protected] and I will include it in the next build.

    Code:
          <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:tag="wrapper_layout">
            <!-- Left column -->
    
            <View
                android:layout_width="226dp"
                android:layout_height="226dp"
                android:layout_gravity="center_vertical|start"
                android:tag="gauge_2"
                />
    
            <!-- Middle column -->
            <View
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="center"
                android:tag="gauge_1" />
    
            <!-- right column -->
    
            <View
                android:layout_width="226dp"
                android:layout_height="226dp"
                android:layout_gravity="center_vertical|end"
                android:tag="gauge_3" />
    
        </FrameLayout>

    Important
    • Each view must contain a tag, which is formated like in the example, where the number corresponds to the Gauge number from the setting screen.
    • The layout which wraps everything together must have a tag called: wrapper_layout
    You are free to use any Layout you want, except ScrollView.


    How to produce bug report?

    Step 1 you need to enabled debugging in OBD2AA app, then follow this instruction set:

    2. Enabling Developer Mode
    1. Open Settings > About phone.
    2. Scroll down to the Build number.
    3. Tap the Build number 7 times in quick succession until "You're now a developer" appears.
    4. Return to the Settings menu and select Developer options.
    5. At the top of the screen, make sure 'Developer options' is set to On (green).
    6. Scroll down to Debugging and enable both USB debugging and Bug Report Shortcut on (green).
    7. Tab on Logger buffer sizes: Default setting is 256K. Select 16M to help capture more information for debugging. Of note, it can affect the apps performance especially with lower spec phone, so change it back after you have finished submitting bug reports.

    3. Capturing a Bug Report
    It's very important to do this right after you experience the issue again, so your device can log at least one occurrence of the issue.
    1. Hold the Power button down until the menu appears.
    2. Select Take bug report. and wait for the device to capture the bug report.
    3. Tap the 'Bug report captured' notification when it appears.
    4. Share the bug report. (I recommend to email it to yourself.)
    5. Download the bug report to your computer.
    6. Send the bug report by email to [email protected]


    I have decided to open up my software, meaning I have made the source code available on GitHub, but it's only available for personal use, and you are not allowed (under any form) to redistribute your own version of the app. You can download and compile it yourself if you wish to do so, and you can implement your own changes for your own personal use, but you cannot create clones of the software which you redistribute under your own name. Source can be found here: https://github.com/borconi/obd2aa.
    Due to the fact that there are some irresponsible developers out there, who created video apps for moving cars, which was one of the main reasons Google blocked 3rd party apps, I won't be updating the code on github any more, to try to prevent those developers to use my technique to overcome the limits. If you are developing a 3rd party app and you will like to know more about how I have done this, you are always welcome to contact me. If your project is something useful, I will be more then happy to share things with you.

    This does not mean it is now a free app and apk can be freely shared!

    Thanks all, this is what keeps me going :) don't worry I haven't given up, finally today I had my exams (passed both) so I will be hitting the road in a couple of hours (1600 miles or 2700km with a few stopovers) so I should be home by Tuesday evening. Once home I'm sure I will find some time for more development.
    17
    I made some really good progress, with the app.
    All you guys with non-rooted phone can expect a public beta this week.
    16
    Non-Root users a gimps of hope for you too as well, today I have managed to move forward from where I was stuck since February with the hack, so hopefully I will be able to make further progress and get it back online in the next couple of weeks for everybody.
    16
    Hi guys. Back in the UK and I'm working on it. Currently still stuck at the same point (SSL related) I will update you as soon as I can, at least testing is much easier now.
