java - Android EventBus app crashes in release mode due to no @Subcribe methods -

the app works in debug, not in release

here's gradle file: https://gist.github.com/rubenwardy/b467d1efd79c671f9a932d98768ff656
here proguard file:

the error still occurs if replace proguard this:

i have @subscribe functions in mainactivity:

@subscribe protected void onperiodchange(final events.periodchangerequestedevent e) {     log.e("mact", "period " + e.from.tostring() + " " + e.to.tostring());     filter = new transactionfilter() {         @override         public boolean isallowed(transaction transaction) {             return transaction.created.gettime() > e.from.gettime() &&                     transaction.created.gettime() < e.to.gettime();         }     };      filtertransactions(); } 

i have, ofc, googled - can't find results. please ask if need more information.

turns out @subscribe methods need public.

@subscribe public void onperiodchange(final events.periodchangerequestedevent e) {     log.e("mact", "period " + e.from.tostring() + " " + e.to.tostring());     filter = new transactionfilter() {         @override         public boolean isallowed(transaction transaction) {             return transaction.created.gettime() > e.from.gettime() &&                     transaction.created.gettime() < e.to.gettime();         }     };      filtertransactions(); }
