Pre-requisite detail:
- Have to use Unity Version 3.5.7 (I can’t use a newer version because this is a school project and the school is unwilling to upgrade or purchase a new license for newer versions)
PROBLEM : (STATED BELOW)
Keep getting error even when building empty scene
Error building Player: Exception: android (invokation failed)
ERROR: unknown error
cmd:android list target -c
stdout;
stderr:
Exception in thread “main” java.lang.NullPointerException
at SDKMain.main(SDKMain.java:62)
I have searched all over the Unity forums and they have all told me to use Revision 21 of Android SDK and I have tried but still get the same error. I am unsure if the reason for failing is because I cannot seem to update my Android SDK platform tools. As seen by the picture below, when i install the Android SDK platform- tools , it is still shown as not installed. Help please. This project will only end when i publish this app.
Extra Info: Even thought the android sdk platform tools says that its not installed, the platform tools folder seem to have installed the information. I am really confused if it was successful or not. If it was succesful, why is Revision 21 not solving the issue of invokation failed. Thanks for the answers in advance.
