java - How can i set an alarm with AlarmManager set() -

i have tried set alarm in android app. failed. have read tutorials don't work me, don't see mistake.

here code:

manifest :

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="com.byethost6.jessy_barthelemy.planificate">      <uses-permission android:name="com.android.alarm.permission.set_alarm"/>      <application         android:allowbackup="true"         android:icon="@mipmap/ic_launcher"         android:label="@string/app_name"         android:supportsrtl="true"         android:theme="@style/apptheme">           <activity android:name=".createtask"></activity>          <receiver android:name="com.byethost6.jessy_barthelemy.planificate.hourreceiver" android:process=":remote"/>      </application>  </manifest> 

i set alarm :

        alarmmanager alarmmanager;         pendingintent alarmintent;         alarmmanager = (alarmmanager)context.getsystemservice(context.alarm_service);         intent intent = new intent(context, hourreceiver.class);         alarmintent = pendingintent.getbroadcast(context, 0, intent, pendingintent.flag_one_shot);          calendar calendar = calendar.getinstance();          calendar.set(calendar.hour_of_day, hours);         calendar.set(calendar.minute, minutes);           alarmmanager.set(alarmmanager.rtc_wakeup, calendar.gettimeinmillis(), alarmintent);         toast.maketext(context, "alarm set", toast.length_short).show(); 

and broadcast receiver :

package com.byethost6.jessy_barthelemy.planificate;  import android.content.broadcastreceiver; import android.content.context; import android.content.intent; import android.widget.toast;  import com.byethost6.jessy_barthelemy.planificate.enumeration.triggerenum; import com.byethost6.jessy_barthelemy.planificate.helper.task;  public class hourreceiver extends broadcastreceiver{     @override     public void onreceive(context context, intent intent) {         toast.maketext(context, "alarm triggered", toast.length_long).show();     } } 

could please me? :)

this alarm in mainactivity

alarmmanager = (alarmmanager)getapplicationcontext().getsystemservice(context.alarm_service); intent intent = new intent(getapplicationcontext(), mybroadcastreceiver.class); pendingintent = pendingintent.getbroadcast(getapplicationcontext(), 0, intent, 0);  // set alarm start @ time. calendar calendar = calendar.getinstance(); calendar.settimeinmillis(system.currenttimemillis()); int curhr = calendar.get(calendar.hour_of_day);  // checking whether current hour on 14 if (curhr >= 13) {     // since current hour on 14, setting date next day     calendar.add(calendar.date, 1); }  calendar.set(calendar.hour_of_day, 13); calendar.set(calendar.minute, 30);  // setrepeating() lets specify precise custom interval--in case, // every day alarmmanager.setrepeating(alarmmanager.rtc_wakeup, calendar.gettimeinmillis(),                 alarmmanager.interval_day, pendingintent); 

and broadcastreceiver

public class mybroadcastreceiver extends broadcastreceiver {      @override     public void onreceive(context context, intent intent)     {         powermanager pm = (powermanager) context.getsystemservice(context.power_service);          powermanager.wakelock wl = pm.newwakelock(powermanager.partial_wake_lock, "tag");          //acquire lock         wl.acquire();          log.v("adebugtag", "it work!");          //release lock         wl.release();     } } 

with code in log can see "it work" when alarm fire!

the manifest

<uses-permission android:name="android.permission.wake_lock" /> <uses-permission android:name="com.android.alarm.permission.set_alarm" /> <receiver android:name=".mybroadcastreceiver" />
