Question Android build fails for normal build but works if "Development Build" option is checked

Hi all,
Unity started acting weird when I try to build my project after implementing ADMob and then I tried to implement in-app purchase. Somehow gradle is broken.
If I chose Development build I can build but the project size become 300 mb (4x normal!!!)
It gives the error messages below;

and api 33

 

Important notice it wasn't api 33 saving my project it was "changing API from one thing to another"
Because then it also happened again (without any clear reason) I changed my API level to 30 then build. Then I changed back to 33 to build it in the latest api.

 

did you solve it ?

 

kinda, I use several packages admob facebook etc. they all use gradle and they all try to install their gradle version with them (1.64 1.72 etc) this time, first I erased the folder "External dependencies" and the folder "Androind (under plugins)) then I installed the last external dependency package and after that didn't let any other pack (by unchecking while installation) any to implement their version.

 

This work out for me.
My problem was when ever i change build version and try to build it failed. so every time when i change version i also change target api to lower version and select api 33 again. and some how build created.

 

Hello,

\Library\Bee\Android\Prj\IL2CPP\Gradle
Deleting 2 gradle folders and all .gradle files in this folder fixed my issue.

Thanks.

 

This works fine! Thanks !

 

I recommend most of the time, when you encounter some build error out of the blue. Just leave the Assets, Packages and Project Settings folder and delete everything else. When you open the project again, it will regenerate the rest.

That fixed this problem for me:
* What went wrong:
Execution failed for task ':launcher:dexBuilderRelease'.
> java.lang.UnsupportedOperationException: This feature requires ASM7

 

Having this issue on Cloud build, so the only solution is to do Clean Builds every so often to stop it from coming back

 

This is worked for me too. Thanks

 

"Clean Build"

 

Set Minimum API Level To "Android 6.0 (API level 23)" because "Android Version 5.0" is not suported Release R8.

 

I've deleted the folder \Temp\gradleOut and then build worked

 

I recommend checking if you haven't suddenly set a parameter in the release build in the 'Project Settings' section "Other Settings" -> Minify. Don't forget to enable debug mode here and disable release mode
