Answer 1

Easier solution: set the environment variable USE_SDK_WRAPPER=1, or hack tools/android.bat to add the line "set USE_SDK_WRAPPER=1". This prevents android.bat from popping up a "y/n" prompt, which is what's confusing Unity.

Answer 2

In my case, I was trying to build and get APK for an old Unity 3D project (so that I can play the game in my Android phone). I was using the most recent Android Studio version, and all the SDK packages I could download via SDK Manager in Android Studio. SDK Packages was located in

C:/Users/Onat/AppData/Local/Android/Sdk And the error message I got was the same except the JDK (Java Development Kit) version "jdk-12.0.2" . JDK was located in

C:\Program Files\Java\jdk-12.0.2 And Environment Variable in Windows was JAVA_HOME : C:\Program Files\Java\jdk-12.0.2

After 3 hours of research, I found out that Unity does not support JDK 10. As told in https://forum.unity.com/threads/gradle-build-failed-error-could-not-determine-java-version-from-10-0-1.532169/ . My suggestion is:

1.Uninstall unwanted JDK if you have one installed already. https://www.java.com/tr/download/help/uninstall_java.xml

2.Head to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

3.Login to/Open a Oracle account if not already logged in.

4.Download the older but functional JDK 8 for your computer set-up(32 bit/64 bit, Windows/Linux etc.)

5.Install the JDK. Remember the installation path. (https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/)

6.If you are using Windows, Open Environment Variables and change Java Path via Right click My Computer/This PC>Properties>Advanced System Settings>Environment Variables>New>Variable Name: JAVA_HOME>Variable Value: [YOUR JDK Path, Mine was "C:\Program Files\Java\jdk1.8.0_221"]

7.In Unity 3D, press Edit > Preferences > External Tools and fill in the JDK path (Mine was "C:\Program Files\Java\jdk1.8.0_221").

8.Also, in the same pop-up, edit SDK Path. (Get it from Android Studio > SDK Manager > Android SDK > Android SDK Location.)

9.If needed, restart your computer for changes to take effect.

Answer 3

I solved the problem by uninstalling JDK 9.

Answer 4

The issue is due to incompatibility of unity with latest Android build tools. For MacOS here's a one liner that will get it working for you:

cd $ANDROID_HOME; rm -rf tools; wget http://dl-ssl.google.com/android/repository/tools_r25.2.5-ma‌​cosx.zip; unzip tools_r25.2.5-macosx.zip

Answer 5

For Mac OS Users :

Go to your Android SDK folder and delete the tools folder (I recommend you to make a copy before deleting it, in case this solution does not solve the problem for you)

Then download the tools folder here :

http://dl-ssl.google.com/android/repository/tools_r25.2.5-macosx.zip

You can find all tools zip version here :

Then unzip the download file and place it in the Android sdk folder.

Hope it helps

Answer 6

Linux Users:

cp -r Android AndroidUnity
cd AndroidUnity/Sdk
rm -rf tools
wget http://dl-ssl.google.com/android/repository/tools_r25.2.5-windows.zip
unzip tools_r25.2.5-windows.zip

In Unity preferences change to this newly created sdk folder.
