Android Build Keeps Failing

Hey everybody, I am rather frustrated with this… I would like to build my entire game and test it on a device. I followed the documentation step by step, reinstalled the unreal engine etc. For some reason my build always fails when I build for android. It builds for windows perfectly fine without any errors, but as soon as I want to build it for android it fails. I am still rather new to the engine itself so I am not exactly sure how to read the output log I get. Not sure what else I could do… Any help is greatly appreciated, as I am almost ready for a early demo release but I can’t test the game on an actual device…
