I'm with Unity 2018.4.2 and Vuforia 8.3.8.

I have already the core-1.7.0 into the Assets/Plugins/Android



But who doesn't have it, it can be downloaded from here:

https://dl.google.com/dl/android/maven2/com/google/ar/core/1.7.0/core-1.7.0.aar



Just to do Vuforia configuration and set the ARCore requirement to OPTIONAL



Works for me! ;)

maybe downgrade to an old version apknite make it works

This works for me. I just follow the steps in the Vuforia page.

Hello,

With Vuforia Engine 8.3, we've added a new configuration setting to specify whether ARCore is be required, optional, or not used at all in an Android application. This can be found in the DeviceTracker section of the Vuforia configuration.

Thanks,

Vuforia Engine Support

Thank you! Life saver! Been stuck on this one for a while o_o

Hello @nuraisyah,

Aside from other solutions which revolve around exporting your project to Android Studio, I found this suggestion: https://forum.unity.com/threads/vuforia-7-2-20-and-android-submission-arcore-com-google-ar-core-min_apk_version-isnt-in-androidma.538843/#post-3608801

Thanks,

The ARCore dependency minimum version code com.google.ar.core.min_apk_version is missing from the AndroidManifest.xml file although the meta-data tag com.google.ar.core has been specified.

I have the same error. what's the real problem here? Can anyone help me fix this. Thank you

Bonjour

J'ai moi-aussi été confrontée au problème :

"Le code de version minimale de dépendance ARCore com.google.ar.core.min_apk_version est manquant dans le fichier AndroidManifest.xml bien que la balise de méta-donnée com.google.ar.core ait été spécifiée."

Après avoir tenté de modifier le fichier xml j'ai finalement résolu mon problème en suivant la procédure expliquée ici:

https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html

J'espère que cette info vous sera utile.

Pour info: Jusque là (-> fin 2018) avec les versions précédentes je n'avais eu aucun soucis, J'utilise maintenant Unity Version 2018.3.1 et Vuforia 8.0.10

Bonne continuation

@Medabit thanks for all of your help! 



We will wait for the next build. In the meantime, do you think its possible to also provide a general android manifest file that would have the proper provisions in it for this issue? 

Hello all,

It is correct that the Vuforia Extension for Unity will write ARCore parameters into the Android manifest file. This means that unless you export your app into Android Studio and build there, there is no way to remove these from the manifest file when building with Unity.

The team is aware of the issue and is investigating methods to expose this option to developers. We hope to have this resolved in our next commercial release.

Thanks for your patience, and apologies for any inconvenience.

You would have to make the directory then and paste the file there.

In step no. 4 can't find " Assets/Plugins/Android directory" . It does not exist.

Adding the AAR file does work but the only issue is if you are like me and rely on using the torch, the AAR file will cause conflicts and the torch will no longer work.  What is Vuforia going to do about this. It needs to generate the proper manifest files.

That cant be the solution! I dont need ArCore, so why should I include the .aar file? That increases the buildsize. The manifest solution did not work for me :/

The work around suggested by tactic worked for as well.



Thanks :)

Writing "com.google.ar.core.min_apk_version" manually ("19" or "24") didn't work for me. You don't have to write it manually. Just download the .aar file from the Vuforia ARCore manual and put it in Plugins/Android even if you are not using the ARCore. With this file Unity writes everything to the Manifest by itself (it writes "com.google.ar.core.min_apk_version" and "com.google.ar.core").

Unity 2018.2.14, Vuforia 7.5.26

Edit "AndroidManifest.xml", on <Manifest> add this line: xmlns:tools="http://schemas.android.com/tools"

Then, right before <application> add this lines:

<meta-data tools:replace="android:value" android:name="com.google.ar.core.min_apk_version" android:value="19" />

  <meta-data android:name="com.google.ar.core" android:value="optional" />

I added these two lines to the AndroidManifest.xml file, immediately after the <application> line, as eduardFrikiwiki did:

    <meta-data android:name="com.google.ar.core.min_apk_version" android:value="24" />

    <meta-data android:name="com.google.ar.core" android:value="optional" />

And that fixed it.

This Solution worked for me running Vuforia 7.5 and Unity 2018.2.13f1 . Thank you :-)

Dear tactic, please,  could you explain in detail where I can find Android.Manifest.xml? I have a one in Pluguins/ GoogleMobileAdsPlugin /

<?xml version="1.0" encoding="utf-8"?>

<!--

This Google Mobile Ads plugin library manifest will get merged with your

application's manifest, adding the necessary activity and permissions

required for displaying ads.

-->

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.google.unity.ads"

    android:versionName="1.0"

    android:versionCode="1">

  <uses-sdk android:minSdkVersion="14"

      android:targetSdkVersion="19" />

  <application>

  </application>

</manifest>

Where I need put the string?

Please, could you explain, how to fix this problem. The ARCore dependency minimum version code com.google.ar.core.min_apk_version is missing from the AndroidManifest.xml file although the meta-data tag com.google.ar.core has been specified) in Unity? Thank you

it Works!! Thank you

Ok, I ran into the problem again. Reinstalling Unity seemed to be what fixed it. I think the Vuforia Android Wrapper in the Unity install files becomes corrupted somehow.

JUST ADD THIS LINE IN YOUR MANIFEST

<application

        android:icon="@drawable/app_icon"

        android:label="@string/app_name"

        android:theme="@android:style/Theme.NoTitleBar.Fullscreen"

        android:debuggable="false">

        <meta-data android:name="com.google.ar.core.min_apk_version" android:value="24" />

        <activity android:name="com.unity3d.player.UnityPlayerNativeActivity"

                  android:label="@string/app_name">

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

            <meta-data android:name="unityplayer.UnityActivity" android:value="true" />

            <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="false" />

        </activity>



        <uses-library android:name="com.osterhoutgroup.api.ext" android:required="false" />

    </application>

I was having the same issue. I would get the same error message when trying to put it on the play store. I believe my issue may have been caused by merge conflicts. In the project, there were already several image targets, and I added a few other image targets that were in other projects by throwing them into unity packages and then opened them into my main project. I tried the fixes listed here and it would then break it on my phone. The screen would just go black and under the output logs through android debug bridge, it said that I had the wrong Vuforia key. The only thing that worked for me was deleting the project off of my computer and re-downloading from the unity cloud. I also reinstalled unity, but I don't believe that that had any effect on fixing the issue. I hope this helps someone.

[SOLVED v2]

I had the same problem, I followed all the instructions below and my APK uploaded fine to Google Play but it crashed on my Samsung S8.

I have Vuforia 7.2.23/Unity 2018.1.2f1

Here is what I did to fix it (note that I am NOT using AR-Kit in my project):

1- DO NOT import the .arr file to Assets/Plugins/Android If you have it there... ERASE IT.

2 - Build your APK from Unity as you usually do...

3 - When Unity builds the APK file it creates a manifest file in this path:

YOUR PROJECT/Temp/StagingArea/AndroidManifest.xml

4 - Copy this AndroidManifest.xml file to your Assets/Plugins/Android directory

5 - Edit the Assets/Plugins/Android/AndroidManifest.xml you just copied

6 - Look for the line:

<meta-data android:name="com.google.ar.core" android:value="optional" />

7 - Insert this line just above it:

 <meta-data android:name="com.google.ar.core.min_apk_version" android:value="24" />

8 - Build, test on your S8 and upload to Google Play :)

It seems Vuforia is forgetting to add the line automatically in the manifest file.

I ran into this problem also. Imported the .aar file  to Assets/Plugins/Android directory.

Now I can upload the app to Google Play Store

BUT this version DOES NOT RUN on my testing phone, Galaxy 8 SM-G950U1

Any ideas?

[SOLVED]

I FIXED IT !  =)

1)  Go to https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html   --  Follow the instructions, just download the .aar file and import it into your Assets/Plugins/Android directory.

2)  TURN Multicore Rendering OFF in player settings.

3)  Make sure ARCore is turned OFF and Vuforia is ON.

Save & Build.

I uploaded to the Google Play Store successfully after this!

I have not tried this yet, but maybe importing the AR Core stuff from Vuforia will fix it?

Here is some info on editing the XML file for AR Core.  But I do not have AR Core enabled, just Vuforia....

https://developers.google.com/ar/develop/java/enable-arcore 

I am having the same issue.  I cannot update my Google Play Store app after the latest Vuforia update.

I had the same issue updating the iOS version on the Apple App Store.  There was a quick fix for that one involving editing the Info.plist file in the Vuforia.framework

https://developer.vuforia.com/forum/unity/vuforia-7220-ios-submission 

Now I am facing the same issue with Google Play Store and Android, but I do not know of any quick fix. *See attached image.  I searched for the XML file and edited it, found the location of the ARCORE reference.  I don't know the syntax for this file though.
