Phonegap - accelerometer app
Phonegap - accelerometer app.Hej jeg er helt ny med at lave apps - har med dreamweaver cs6 lavet nogle app der er mere eller mindre bare er hjemmesider i en app. nu vil jeg gerne prøve at bruge nogle af de muligheder der er i phonegap API og bruge telefonens hardware. til at starte med vil jeg "bare" gerne lave en app som kan vise og gemme data fra accelerometeret i en fil... men da jeg allerede ikke virker med accelerometeret, er det det jeg vil spørge jer om i måske kan fortælle mig havd jeg gør galt i denne kode som bare skal vise data fra accelerometeret.
her er min kode (tyv stjålet fra nogle hvor jeg ka se det virker...)

nogle der kan give et godt bud på hvad jeg gør galt siden at koden, som skulle virke, ikke gør det hos mig?
