This message is e.g. shown if you have a license key that is not valid for a certain SDK version. If you e.g. have a key for SDK 7.0 and you try with SDK 7.1 you'd get this message.
Please check the versions and for which versions the license key is valid. If you have any non-technical questions, please send an email to sales[ at ]wikitude.com.

Hello,
im trying to setup the example scene for android studio, but it keeps saying "license key missing". The key is working fine in the unity example.
I've setup a new project and followed the instructions accourding to https://www.wikitude.com/external/doc/documentation/7.0/android/setupguideandroid.html#setup-guide-android
Anyone got the same problem?
