Why do I have a NullPointerException here? I checked my code for 5 times…
When I install my app on my Galaxy S it works. But when I rebuild it without changing the code it crashes. Could you explain me why? Thanks in advance!

Typical non-initialization stuff… gewicht is null, probably not initialized.
EDIT: You call
onProgressChanged()(triggered whenseek_gewichtt.setProgress(gewicht_mark_int);)before
