I tried to use Calendar app (Calendar.apk in system) but I got an empty "Add an account" page.
My device is a PRS-T1 with rupor's AMR and App2SD package.
I copied the apk, removed it from /system/app and tried to reinstall it as an user app (i.e. in /data/app) but when I tried DEXOPT raised an error because the package doesn't contain classes.dex
Is Calendar.apk from stock rom missing something or is my blank screen due to rupor's e-ink friendly theme hack?
Has anyone succeded using the default Calendar app?
