android - AlarmManager 没有在预定时间触发？

Question

我已经在我的 android 应用程序中实现了 alarManager。本次闹钟重复定时时间为 5 秒。但不是一分钟后重复 5 秒警报。

AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

intent.putExtra(Constants.Extra.SERVICE_TYPE, Constants.Extra.SERVICE_TRIGGER);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 123456789, intent, 0);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 5000, pendingIntent);

接收类

@Override
    public void onReceive(Context context, Intent intent) {
        Bundle extras = intent.getExtras();
        if(extras != null){
            String type = extras.getString(Constants.Extra.SERVICE_TYPE);

            if(type != null && type.equalsIgnoreCase(Constants.Extra.SERVICE_TRIGGER)){

                //Triger  

            }
        }
    }

list .xml文件

<uses-permission android:name="com.android.alarm.permission.SET_ALARM" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<!-- Receivers -->
<receiver android:name=".receiver.ServiceTrigger">
    <intent-filter>
        <action android:name="com.project.ServiceTrigger" />
    </intent-filter>
</receiver>

对我有用

使用这个

 alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(),
            pendingIntent);

代替

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 5000, pendingIntent);
