Question

Android

When compiling a project on android in Unity, it gives the following error:
Failed to recompile android resource files
Full error:

CommandInvokationFailure: Failed to recompile android resource files.
C:/Program Files/Java/jdk-14.0.2\bin\javac.exe -bootclasspath "C:/Users/zZaKko64/AppData/Local/Android/Sdk\platforms\android-30\android.jar" -d "C:\Users\zZaKko64\Desktop\SuperMegaCaseSimulator\Temp\StagingArea\bin\classes" -source 1.6 -target 1.6 -encoding UTF-8 "com\google\unity\R.java" "com\google\unity\ads\R.java" "com\unity3d\EditorPlugin\R.java" "com\zzakko\casesimulator\R.java"

stderr[

stdout[

UnityEditor.Android.PostProcessor.Tasks.TasksCommon.Exec (System.String command, System.String args, System.String workingdir, System.String errorMsg, Int32 retriesOnFailure)
UnityEditor.HostView:OnGUI()

I searched Google for a solution, but I couldn't figure out why it was, and in the end I didn't understand how to solve it.
If someone has come across or knows a solution, I will be grateful!

Answer 1

Install jdk 8 instead of the current one. And change it in Unity.
