Unity 2017.3.1f1 CommandInvokationFailure: Unable to list target platforms.

Hey there, I have tried everything I can find. I've tried reinstalling the SDK and some other stuff. There has to be something I'm not doing or seeing. Whenever I try to export to an APK I get 4 errors. I'm not really sure what to do at this point so i you guys have any suggestions that would be greatly helpful.

This is the main error.

CommandInvokationFailure: Unable to list target platforms. Please make sure the android sdk path is correct.
C:/sdk\tools\bin\avdmanager.bat list target -c

I got the same problem. This method from Stackoverflow does not work. https://stackoverflow.com/questions...player-for-android-in-unity/36959457#36959457

 

I found the solution.

The tools directory inside the Android SDK directory needs to be replaced from the one that we can download from here: https://dl.google.com/android/repository/tools_r25.2.3-windows.zip?hl=id

 

This actually worked! Thank you so much!

 

También me funcionó muchas gracias!!

 

what jdk are you using? Last version 8 (http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) ? The jdk path should be this one, not AndroidStudio stuff right?

I tried this method several times but still doesn't work, can som1 do a step by step tutorial how to get this working? Stack and Forums aren't helping...

 

For me with latest Android build tools and latest JDK worked with 2017.x and 2018.1x / 2018.2x versions by setting JAVA_HOME and below ANDROID_HOME paths.

set ANDROID_HOME=C:\ installation location \android-sdk

set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools

 

Worked for me !

 

Worked for me! I set environment variables and this solution worked even without restarting Windows 10
