Did you ever figure this out? I'm receiving the same error...

 

Maybe it is a similar problem to one I had at some point.

You could try reinstalling the unity editor through unity hub and make sure you have Android build support checked during the installation.
Your settings seem fine. My guess it has to do something with the android NDK or SDK not installed properly.

Look at this thread to see the problem I had:
https://forum.unity.com/threads/ans...ects-with-il2cpp-enabled.708401/#post-4736906

 

I solved this by unchecking the use custom gradle template option. This is in Project Settings > Player > Build > Custom Gradle Template. This is because I had upgraded my unity version and to get it to work I needed a custom gradle file, which had set the gradle plugin version to "classpath 'com.android.tools.build:gradle:3.0.1'", but it needed a higher version. Once I unchecked the use custom gradle template option, the generated "Temp/gradleOut/build.gradle" file set the plugin version to 3.4.0 and it fixed the problem.

 

"android.defaultConfig.versionCode is set to 0, but it should be a positive integer."
I think this is the reason for your error. Change your version code to value > 0

 

Where did you find android.defaultConfig.versionCode ?

 

I am facing this problem with no workaround I got the same error from unity 2019 and I have updated to version 2020 still the same error please give me the solution thank everyone

hello
go to Assets\Plugins\Android and remove all content then
in unity editor in Assets menu go to Play Service Resolver(or external play resolver) >Android Resolver>Resolve
now everyThing is oK!

 

this isnt ideal, but i shift deleted the entire gradle cache, it worked!
C:\Users\you\.gradle\caches

 

Try to update all the packages in the package manager. I helped me to resolve the issue.
Window -> Package Manager

 

Thank you this solution worked for me

 

Where did you find android.defaultConfig.versionCode ?

 

file -> build settings -> player settings -> under other settings section(Bundle Version Code)

 

file > build settings > player settings > minimun API Level and up one Version Api And Test,

sometimes a pluggin needs a newer Api version

 

I just had this with Unity 2020.3.5f1 where we had Onesignal SDK in which required a custom gradle file but after doing a build during the same session, then removing onesignal and then unticking the custom gradle file tickbox, Unity didn't clear out the cached version in the Temp folder when we tried to build after!

 

maybe it will help someone. I had a similar error with HMS plagin, I redid a lot of tips and nothing helped, it helped that I demolished firebase from the project and the error disappeared.

 

I cant find cache in my gradle folder

 

I faced similar problems when integrated Applovin Max and tried to build Android app on Unity 2020.
Solved by setting

classpath 'com.android.tools.build:gradle:3.6.0'

in custom gradle file. Didn't work with 3.4.0

 

ac hacnge in gradle version? can u olease tell where to find the path?

 

I'm getting the same errors on an Oculus Quest 2 project I am trying to build. The build ran successfully yesterday, but randomly stopped working with these errors even though I did not change the settings. I've tried several solutions mentioned here but nothing has worked.

 

I had similar problem.
All I did was lower the Target API Level to something like Android 10.0.
And it built successfully.

 

It worked to me. Thank you

 

I also only started getting this error after importing firebase into my project. I solved it by generating a .aab instead of a .apk. To do this, go to File->Build Settings and check the box for "Build App Bundle (Google Play)" then when you do a Build or Build and run, you'll notice that it asks you where to save the .aab instead of .apk

 

Still having the error

 

How to troubleshoot build failures:

First, make a blank project with a single blank scene and prove that it builds successfully.

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

Android build not building:

Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

https://forum.unity.com/threads/cant-build-for-android.1306098/

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

Android Gradle errors and other related stuff:

https://forum.unity.com/threads/unity-gradle-bug-please-help.1368018/#post-8625789

 

Hello, I was having the same issue. It started after update to unity 2022.2.1.
Tried like 10 solutions i was able to find, the only one that helped was to go to C/Users/<yourname>/.gradle and purge the entire folder. On next build unity rebuild the folder and it seems to work fine now.

 

Similar issues. I deleted the /Assets/Plugins/Android folder and then selected "Clean Build..." instead of just hitting "Build". The build succeeded! I'm not sure if both steps were necessary. I'm on 2022.2.11



UPDATE: I had the same project (at the same git commit) on both my laptop and desktop and tried this:
DESKTOP:
- Deleted Android folder and ran "Clean Build" - success
LAPTOP:
- Tried just running "Clean Build" - failed
- Tried deleting "Android folder and running a normal build - success

I'd first try deleting the folder with the manifest, then if that doesn't do it, try a build again with "Clean Build".

 

The problem is that the SDK folder needs to be readable on Windows explorer, and Windows always makes the folder read-only automatically. I used to be able to make the folders non-read-only which made my code compile, but now it is not letting me change the status of the SDK from read-only to readable.

 

So basically, I copied the SDK folder to documents, uniticked the read only, and changed SDK the folder on Unity preferences. Apparently there is a lock on the usual unity java SDK folder, so by moving it to folders I was able to bypass this issue and make my code compile.

 

On Unity 2023 I had this issue and updated the manifest to a C# template and it worked.

 

Could you elaborate a bit on how to do that ?

 

tnx to @donat_01 now i got the build.
i raised the "Minimum API Level" to Android13.0 then it gave me an update option for the SDK, did the update now i can build with every API Level. ty very much <3
Unity Version: 2022.3.7f1 LTS

 

This is what fixed it for me too in 2022.3.2f1.

Thank you!

 

That one just worked fine for me as well.
Thanks a lot

 

Worked for me too. Thank you very much.

 

This also fixed it for me, 2022.3.9!!! thank you !!!

 

Thank you so much. This fixed my problem

 

Yep, exactly the same, raised it to Android13.0, it offered an update when I hit Build, and after three agonising days, I got it to build the apk. Thanks @donat_01 for the answer to this problem!!
