Alaram not firing

Question

내 경보가 전혀 발사되지 않습니다.

MainActivity :

final Context context = this; 

    Calendar calendar = Calendar.getInstance(); 
    calendar.setTimeInMillis(System.currentTimeMillis()); 
    calendar.set(Calendar.HOUR_OF_DAY, 13); 
    calendar.set(Calendar.MINUTE, 30); 

    Intent intent = new Intent(context, AlarmReceiver.class); 
    PendingIntent alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0); 

    AlarmManager alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
    alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),AlarmManager.INTERVAL_DAY, alarmIntent); 

AlarmReceiver :

public class AlarmReceiver extends BroadcastReceiver { 

    public static String NOTIFICATION_ID = "notification-id"; 
    public static String NOTIFICATION = "notification"; 

    @Override 
    public void onReceive(Context context, Intent intent) { 

     NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); 

     Notification notification = intent.getParcelableExtra(NOTIFICATION); 
     int id = intent.getIntExtra(NOTIFICATION_ID, 0); 
     notificationManager.notify(id, notification); 

    } 
} 

매니페스트 :

<uses-permission android:name="android.permission.WAKE_LOCK"/> 
    <uses-permission android:name="android.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=".MainActivity"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 

       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
     <receiver android:name=".AlarmReceiver" /> 
    </application> 

</manifest> 

사용 : compileSdkVersion 25의 minSdkVersion 23 targetSdkVersion을 25

API (23)의 경우와 위

Answer 1

는) setAndAllowWhileIdle를 (사용할 수 있습니다

는

그래서 당신의 코드를 변경 :

if (Build.VERSION.SDK_INT >= 23) 
     alarmManager. setExactAndAllowWhileIdle(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); 
else if (Build.VERSION.SDK_INT >= 19) 
    alarmManager.setExact(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); 
else if (Build.VERSION.SDK_INT >= 16) 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), 1 * 1000 * 60 * 60 * 24, pendingIntent); 

하고 작업인지 여부를 확인합니다.
