Guten Tag ich bin es mal wieder,
ich habe nun ein Problem. Ich möchte gerne eine neue Activity aufrufen per ButtonClick, das Problem welches ich jedoch habe ist, dass mir ADT/Eclipse keinerlei Fehler ausspuckt. Die App jedoch abschmiert sobald ich auf den Button drücke.
AndroidManifest.xml
Code
<?xml version="1.0" encoding="utf-8"?>

jedoch kann ich doch rein theoretisch alles dabei lassen wenn ich die Button bzw. das Layout auf/in der activity_main.xml ausarbeite oder? =)
