After device reboot alarms set in Alarm manager are cleared - docs
You need to initialize Alarm manager again in your on BOOT_COMPLETED receiver. You can use sharedPrefference to store the time you need to set your alarms
In onClick of the activity add
SharedPreference preference = PreferenceManager.getDefaultSharedPreference(this);
preference.edit.putInt("timeInterval",INTERVAL).apply;
Then in onReceive in the receiver:
SharedPreference preference =
PreferenceManager.getDefaultSharedPreference(this);
int interval = preference.getInt("timeInterval", 4000);
alarm.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),interval, pintent);
