Android Repeat alarm (daily) implementation

Mainactivity as follows:

Package Cc.cc;import Java.util.calendar;import Java.util.locale;import android.os.bundle;import Android.app.activity;import Android.app.alarmmanager;import Android.app.pendingintent;import Android.content.context;import android.content.intent;/** * Demo Description: * Recurring ALARM Implementation * * NOTE: * 1 because we are going to implement the two alarms every morning eight o'clock and eight o'clock in the evening, they are duplicated . * So it's easy to make mistakes in Pendingintent.getbroadcast (). The alarm clock that causes the eight o'clock * is invalid. The main reason is because of the fourth parameter of the method. * Workaround: Set two action for Broadcastreceiver, and use different action when generating intent *, so that two alarms will work. * If there is a better way, please leave a message to say, thank you. * 2 in the Calendar.set (Calendar.hour_of_day, 8) The second parameter of the method * denotes hours, please fill in the 24-hour format. What time does the device take? * Standard (12 hours or 24 hours) * Reference: * 1 htt p://blog.csdn.net/hudashi/article/details/7060837 * 2 http://blog.csdn.net/wdaming1986/article/details/6745655 * 3 http://blog.csdn.net/z1074971432/article/details/17532139 * Thank you very much * */public class Mainactivity extends Ac tivity {@Overrideprotected void onCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (r.layout.main); sendalarmeverYday1 (this); SendAlarmEveryday2 (this);} private void SendAlarmEveryday1 (context context) {Alarmmanager Alarmmanager = (alarmmanager) getsystemservice ( Context.alarm_service);    Calendar Calendar =calendar.getinstance (Locale.getdefault ());    Calendar.settimeinmillis (System.currenttimemillis ());    Calendar.set (Calendar.hour_of_day, 8);    Calendar.set (Calendar.minute, 30);    Calendar.set (Calendar.second, 0);    Calendar.set (Calendar.millisecond, 0);    Intent Intent = new Intent ();    Intent.setaction ("Testalarm0");    Pendingintent pendingintent=pendingintent.getbroadcast (context,0, intent,pendingintent.flag_cancel_current); Alarmmanager.setrepeating (Alarmmanager.rtc_wakeup,calendar.gettimeinmillis (), Alarmmanager.interval_day, pendingintent);} private void SendAlarmEveryday2 (context context) {Alarmmanager Alarmmanager = (alarmmanager) getsystemservice ( Context.alarm_service);    Calendar Calendar =calendar.getinstance (Locale.getdefault ()); Calendar.settimeinmillis (System.currenttimemillis());    Calendar.set (Calendar.hour_of_day, 20);    Calendar.set (Calendar.minute, 30);    Calendar.set (Calendar.second, 0);    Calendar.set (Calendar.millisecond, 0);    Intent Intent = new Intent ();    Intent.setaction ("Testalarm1");    Pendingintent pendingintent=pendingintent.getbroadcast (context,0, intent,pendingintent.flag_cancel_current); Alarmmanager.setrepeating (Alarmmanager.rtc_wakeup,calendar.gettimeinmillis (), Alarmmanager.interval_day, pendingintent);}}
