[Solved] Android Build Error

Problem fixed here : https://youtu.be/-wQ39MQm990

Hello I am a Korean developer. I also had a headache for 3 days because of this problem. However, it resolved. I build on PC successfully, but the error came out on my laptop. The problem is the library folder within your project. EX) C:/UnityProjects/Bottle Flip Simulator/Library/..

I compared the folder C:/UnityProjects/Bottle Flip Simulator/Library on my PC with C:/UnityProjects/Bottle Flip Simulator/Library on my laptop and found that there were no 'Il2cpp' related folders inside. So I copied the Library folder on the PC, deleted the Library folder on the laptop, and then pasted it.

Paste the library folder in the project that builds successfully.

@dctunity I'm making new game and I'm getting the same error as above. (I gave up building Bottle Flip Simulator) So, I checked Library folder and there is three folders related to 'Il2cpp' . 1. il2cpp_android_arm64-v8a, 2. il2cpp_android_armeabi-v7a 3. Il2cppBuildCache Weird thing is that I succeeded building 3 times. I even tried reinstalling Unity but I get an error. This is the error I'm getting. (I think this is same as error above)

 Exception: Failed running C:\Program Files\Unity\Hub\Editor\2020.3.2f1\Editor\Data\il2cpp/build/BeeSettings/offline/bee.exe --useprebuiltbuildprogram --no-colors

The soludion with deleting cache only works until the next build attempt. I was trying different Unity versions, clearing all possible Temp/AppData folders, with no luck. This error is a sticky shit, can't get it working.
