Hello, I’ve made a project with a few scripts and graphic settings. Then I installed the Android Works like in the description of the documentation. But it don’t works. At the end of the packaging there it says ‘Unknown Error’. I don’t know what to do. ‘Das System kann den angegebenen Pfad nicht finden’ means ‘The system can’t find the given path’, for them, who don’t speak German.
Ah yes, this issue still exists but a resolution found here works: packaging for android fail on 4.9 (was working on 4.8) - UE4 AnswerHub
Go into Edit->Project Settings in the UE4 Editor.
Scroll down to Android SDK under platforms.
Set SDK API Level to: matchndk
Set NDK API Level to the API level you wish to use - android-19 worked for me.
