Question

我正在尝试在我的应用中创建每周提醒。为此我使用AlarmManager。这是代码生成警报

pendingIntent = PendingIntent.getBroadcast(SettingsActivity.this, 1234567, new Intent(SettingsActivity.this, WeeklyReminder.class), 0);
AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);                  
Calendar calendar = Calendar.getInstance();       
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.add(Calendar.SECOND, 30);
long updateFreq = 30*1000;//24*60*60*1000;
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), updateFreq, pendingIntent);

这是扩展广播的每周余数类

public class WeeklyReminder extends BroadcastReceiver
{

    @Override
    public void onReceive(Context context, Intent intent) 
    {
        // TODO Auto-generated method stub
        try
        {
            System.out.println("Alarm Initiated");
            Toast.makeText(context, "Recieved Alarm", Toast.LENGTH_SHORT).show();
        } 
        catch (Exception e) 
        {
            Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show();
            e.printStackTrace();
        }
    }

}

在androidmanifest.xml中，我在标记

之前有这个条目

<receiver  android:name="WeeklyReminder">

我希望即使应用关闭也会调用提醒。但现在什么也没发生这是正确的做法吗？感谢

我解决了这个问题，并将其用于将来可能会遇到同样问题的人。在androidmanifest文件中，我错过了'。'即代替“.WeeklyReminder”我使用的是“WeeklyReminder”

所以正确的输入是

<receiver  android:name=".WeeklyReminder">

在Android应用中创建提醒
