Game Doesn't Install on Android 12 from Playstore

Hello.

We have recently released our game to the Playstore and i found out (From coments) that people running Android 12 can't install the game. The game has more than 2k installs on other devices running Android 11 or earlier.

The message that the users get is: "Can't Install"
"Try again, and if it still doesn't work, see common ways to fix the problem"

Does anyone experience similar problem? The game was build with Unity 2019...

 

Edit:

Most likely the issue is not having exported flag for the unity activity which is a requirement from Android 12. This can be solved by updating your unity to latest version.

If you can't update or if unity hasn't back-ported to 2019, you can try the below script.

How to use?
1. Copy the contents of the share code into AndroidManifestPostProcessor.cs file
2. Place it under your Assets/Editor folder. (this is folder of your unity project)

 

Hi!

I've updated to 2020.3.25.f1 and I still have get the error when I try to update one existing app: "You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher. See: developer.android.com/about/versions/12/behavior-changes-12#exported"

Also, I've selected "Custom Main Manifest" (Project Settings > Player > Android > Publishing Settings > Build), and added android:exported="false" (one time) and android:exported="true" (another time) in AndroidManifest.xml, but still same error. Tried this with 2020.3.25.f1 and 2019.4.28f1.


I want to try your method, but I'm not very advanced... From my undestanding you said to create a c# file and to add the code you posted? if yes, then where exactly that file need to be placed?

Thank you!

 

1. Copy the contents of the share code into AndroidManifestPostProcessor.cs file
2. Place it under your Assets/Editor folder. (this is folder of your unity project)

 

Thanks for the code but it throws compilation errors on anything referencing "EssentialKit", starting with
namespace VoxelBusters.EssentialKit.Editor.Android. Is there a way to fix this ?

 

Hello, thanks for your help, I followed the steps but I had these errors, any solution? I will be grateful.

Assets\Editor\AndroidManifestPostProcessor.cs.cs(21,24): error CS0103: The name 'EssentialKitSettingsEditorUtility' does not exist in the current context

Assets\Editor\AndroidManifestPostProcessor.cs.cs(15,13): error CS0246: The type or namespace name 'EssentialKitSettings' could not be found (are you missing a using directive or an assembly reference?)

 

I think I have solved it.
I deleted this part of the code that you shared:

Code (CSharp):

1.  
2. EssentialKitSettings settings;
3.              if (!EssentialKitSettingsEditorUtility.SettingsExists)
4.              {
5.                  return;
6.              }
7.              settings = EssentialKitSettingsEditorUtility.DefaultSettings;
8.  

No problem to build, and I was able to update my application.
Do you think I have a problem with the way I edit the code?
Thanks for your help.

 

It doesn't really matter since the bundle still cannot be published for the same reason.
I tested.

 

Your problem must be different from mine because I can publish my app by editing the code in the way I explained before.

 

Can you please explain me what exactly you did?
My issue is that if I try to upload my app bundle to the Play Store, I get this error:

"You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher."

I tried to insert android:exported="true" into AndroidManifest.xml but it didn't solve the issue.
I tried to insert the code above (deleted the part you also deleted) into the Assets > Editor subfolder, but it didn't solve the issue.

What the hell am I supposed to do?

 

go to assets/editor and create a script AndroidManifestPostProcessor.cs paste this:

build new apk/aab and upload

 

I did the same exact thing, no success. Can you share your AndroidManifest.xml file which is inside Assets > Plugin > Android?
Maybe there is something inside which I might have wrong...
Does your game use Google Play Services (achievements or leaderboard)?

 

Thanks for pointing the compilation error. I should have removed it earlier but was in rush
Anyways, I removed those lines and it should be fine for anyone now.

 

Share me the a dummy apk (with no scenes added in the build settings) to have a look at it.

 

I tried everything but unable to upload publish on Google Play.
What I did?
1- Update my unity version
2- I added android:exported="true" in manifest
3- I added your script in editor folder

I didn't understand what I have to do ? Very annoying issue...

 

How are you all adding exported = "true"? It needs to be inside the activity tag.

 

I added as attached.

 

I don't think it's needed inside meta data, but the other one seems correct to me.

 

Problem is here

Code (CSharp):

1. <receiver android:name="com.unity.androidnotifications.UnityNotificationRestartOnBootReceiver" android:enabled="false">
2.             <intent-filter>
3.                 <action android:name="android.intent.action.BOOT_COMPLETED"/>
4.             </intent-filter>
5.         </receiver>

Your mobile notifications need to have android:exported flag as its using intent-filter as per Android 12.
Try checking if you see an update from that plugin. It should resolve it.

 

Thank you very much. I removed Mobile Notifications package and it's fixed. I think this package coming as default. If you don't use you should remove that.

 

Yikes! I didn't expect that

 

Hello

I am having the same problem and used the script above, but doesn't solve this error. Can anyone confirm this is also a problem with 2021.3.26f1?

 

Share an empty apk or merged manifest file from build folder of Temp/gradleOut once you make an apk/aab.

 

Hey guys! I think I'm having the same issue with Unity Mobile Notifications (UnityNotificationRestartOnBootReceive seems to be the culprit here) but we need mobile notifications! I have the latest version of that package currently (1.3.0) and we're using unity 2018.4... Is there a way to insert exported:true into that single event via postprocessor or anything else?

 

Check this post.

 

Doesn't look like its related to the issue we are talking about in this thread. Share the log details of the crash to explore more details.

 

This is the message I get when trying to upload the apk/aab to the PlayStore:

You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher. See: developer.android.com/about/versions/12/behavior-changes-12#exported

 

The manifest you shared seems to be proper though. I assume some data i missing mostly if you get that error.
Pass me an empty APK (with all scenes disabled from build settings) to look into.

how to work on unity 2019.2.1 androidmanifest file change

 

The script shared above should fix it. Actually it works from 2018.4+
P.S. Please don't use wrong text formatting and make the question more descriptive.

 

Hi, I used the script above using Unity 2019.2 and I finally able to submit the abb.
But the app goes black screen after showing unity logo only on android 12, anyone encountered the same issue?

 

If its exported flag issue, you can't even install the apk on Android 12. Share complete logcat log.

 

I did the same things you described here and Really it worked, You have saved a lot of my production time. thanks a lot man

 

Glad its helpful

 

Im having same issue with UTNotifications package, im adding the android:exported into the manifest file provided with the plugin, but for some reason a dont understand when the apk is built, this android:exported disapears from the merged androidmanifest file inside the apk

 

Strange.
Did you try the script shared above? Thats added at the last step to make sure it exists. Let me know if it doesn't work for you. Also, recent unity versions (including LTS) already have the exported flag by now mostly.

 

Hi there!
Yeah i have added the script from above, but for some reason i have still the same issue, im leaving attached my final merged androidmanifest (Extracted from inside apk, as a txt file since unity forum dont allow me to upload xml files)

On the android manifest file within the plugin i have modified to this

<!-- Restore Scheduled Notifications On Reboot -->
<receiver android:name="universal.tools.notifications.ScheduledNotificationsRestorer" android:exported="false">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>

but for some reason after building:


<receiver android:name="universal.tools.notifications.ScheduledNotificationsRestorer">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>

 

Update your Facebook and vrcore plugins. They seem to miss the exported flag.

 

that's another issue hahahaha, i dont know why theres a vrcore reference there, our app isnt using anything about vr, xr, ar, nothing, its a plane simple 2d game

 

i removed all the manual tags i added on the manifests inside my unity project, and built the game again using this processor, and the result was a bit different

 

exported flags for com.unity.purchasing.googleplay.VRPurchaseActivity and universal.tools.notifications.ScheduledNotificationsRestorer are missing. This can create a launch/install crash.

 

Any hints on how can i add the exported flags for those?
I have added the AndroidManifestPostProcessor.cs to my project and it wont add the exported tags to those fields.

for com.unity.purchasing.googleplay.VRPurchaseActivity I dont find any reference in the entire project, i really dont have a clue about from where this is comming.

but for universal.tools.notifications.ScheduledNotificationsRestorer i have it on an AndroidManifest.xml file in the project, but even adding the tag in that xml, it seems to be gettting deleted from the final merged xml file.

This is driving my crazy and i dont find any solution yet.

Any hints would be really appreciated! Thanks!

 

I Have finally managed to solve it.
From the UTNotifications Plugins, i found there was 2 androidmanifests for the plugin, i've decided to merge them manually and delete the one inside editors folders.

For the VRCore part of the manifest, it was an AndroidManifest.xml that was placed inside GooglePlay.aar inside the unitypurchase plugin, i had to open it with a zip compressor, extracted, edited it and put it again inside the aar file

And problem solved.

Thanks for all of your help!

 

Sorry, i just saw your messages.

There is an alternative where you can add another manifest and use tools override option to overwrite other manifest files.

 

this made me so angry, i tried every way on internet,i wasted 1 day on internet still not found the solution
here my android manifest ;

https://www.dropbox.com/s/r6lgfwk5crg6mg9/manifest.rtf?dl=0

 

You may need to update your OneSignal plugin as receivers declared with intent-filters doesn't explicitly state exported flag.

 

okay i solved problem by target api 30 level,but I will try your solution.
What may I lose if I use target api level 30?

 

Starting November this year, every update on Google Play must be Level 31 at least.

 

How can I disable OneSignal for android?
I am using OneSignal only for iOS

 

Well, I'm not sure if there is a direct way to disable it. Basically just find the android manifest generator/manipulator and try commenting the lines which are adding entries in the manifest. Finally disable the jar/aar related to onesignal in the inspector by selecting that file.
