Hallo,
meine erste "größere" App nach Hello World
Einfach ein paar Dinge ausprobieren...
Aber: nach einiger Zeit hängt die App, Home Taste auch im Sekundenbereich.
Fällt jemandem was auf? Was muss anders? Wie grenze ich das Problem ein?
Neben dem Code unten habe ich im Manifest noch Landscape festgeschrieben.
Vielen Dank für die Mühe!
