在我的应用程序中,我需要每隔午夜运行一些代码。这是我第一次开始报警服务,并在网上搜索了一些片段和示例。
下面是我的代码,它没有按预期工作,请帮助我指出我的错误:
设置重复警报
private static void initiateMidnightAlarm(Context context, AlarmManager alarmManager) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 0);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
PendingIntent midnightIntent = PendingIntent.getService(context, 0,
new Intent("com.alarms.MidnightProcess"), 0);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, midnightIntent);
}
在清单中宣布收件人:
<receiver
android:name=".receivers.MidnightProcessReceiver"
android:enabled="true"
android:exported="false">
<intent-filter>
<action android:name="com.alarms.MidnightProcess"/>
</intent-filter>
</receiver>
RECEIVER CODE:
public class MidnightProcessReceiver extends BroadcastReceiver {
public MidnightProcessReceiver() {
}
@Override
public void onReceive(Context context, Intent intent) {
processMidnightLogic(context);
}
public static void processMidnightLogic(Context context) {
Toast.makeText(context,"MidnightProcessReceiver",Toast.LENGTH_LONG).show();
}
}

请帮忙!

由于您需要触发隐式广播,而不是启动服务,因此您需要检索错误类型的PendingIntent。变化:
PendingIntent midnightIntent = PendingIntent.getService(context, 0,
new Intent("com.alarms.MidnightProcess"), 0);
为:
PendingIntent midnightIntent = PendingIntent.getBroadcast(context, 0,
new Intent("com.alarms.MidnightProcess"), 0);
