Hello everyone,
I keep getting a error well exporting my game to a apk file.
I installed the sdk and jdk and put the path in the external tools area.
This is The senario:
with 2 warnings:
This is due to an issue with a recent version of the Android SDK.
You can read how to solve it here: Unity Issue Tracker - Android Build fails when the latest Android SDK Tools 25.3.1 version is used
problem is solved thanks @liortal
