android.content.res.Resources$NotFoundException:String ressource ID #0x2 Database

lblMin.setText(jour.getmTempMin());
lblMax.setText(jour.getmTempMax());

Du kalder setText(int) der forventer et ressource-id. For at bruge setText(CharSequence) i stedet kan du ændre koden til f.eks.

lblMin.setText(String.valueOf(jour.getmTempMin()));
lblMax.setText(String.valueOf(jour.getmTempMax()));
