android - What happens when two apps define same BroadcastReceiver class in their manifest? -
i have android library project broadcastreceiver class , scheduler class defines methods setting repeating pendingintent broadcastreceiver
//delay alarmmanager setrepeating method in seconds //id requestcode pendingintent public static void schedulebroadcast(context context,int delay,int id){ intent intent = new intent(context, superreceiver.class); intent.putextra(key_delay, (long)(delay * 1000)); intent.putextra("app_name", context.getpackagename()); long timegap = (long)(delay * 1000); pendingintent alarmintent = pendingintent.getbroadcast(context, id, intent, pendingintent.flag_cancel_current); alarmmanager alarmmanager = (alarmmanager) context.getsystemservice(context.alarm_service); alarmmanager.setrepeating(alarmmanager.rtc_wakeup, system.currenttimemillis() + timegap, timegap, alarmintent); } the receiver
@override public void onreceive(context context, intent intent) { log.e("chirag-library","superreceiver received!"); long delay = intent.getlongextra(bscheduler.key_delay, -1); log.e("chirag-library","delay "+delay+" ms"); log.e("chirag-library", "by app called "+ intent.getstringextra("app_name")); log.e("chirag-library",context.getpackagename()); } i using project dependency in 2 of apps define receiver in manifest in exact same way
<receiver android:name="com.chirag.library.superreceiver"/> i call schedulebroadcast() both of apps different delay value.
in com.chirag.appone
bscheduler.schedulebroadcast(getapplicationcontext(), 10,111); in com.chirag.apptwo
bscheduler.schedulebroadcast(getapplicationcontext(), 60,999); is onreceive() called both apps when 1 of pendingintent fired?
is because pendingintents have same receiver intent?
logcat shows logs in onreceived fired @ same time seconds

what happening here?
is onreceive() called both apps when 1 of pendingintent fired?
no. here's why: intent fed pendingintent explicit intent , makes onreceive application context specific , hence both apps have own receiver same name.
what more confusing me why 10s delay appone fired once between 60s delay apptwo?
after bug research on setrepeating() , found https://code.google.com/p/android/issues/detail?id=161244
which says on api >= 21 setrepeating() interval value reset 60s if less 60s(this not documented) happened case.
hence first time seem fire off @ different time intervals(currenttime + 10s , currenttime + 60s respectively) , later both fired @ intervals of 60s.also setrepeating() not yield seconds accurate events both of onreceive seemed fired @ same time leading confusion
