在 Android 应用程序中创建提醒
我正在尝试在我的应用程序中创建每周提醒。为此，我使用 AlarmManager。 这是生成警报的代码
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剩余类
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，我在标签之前有此条目，
<receiver android:name="WeeklyReminder">
我希望即使在应用程序关闭时也能调用提醒。但现在什么也没发生 这是正确的做法吗？ 谢谢
I am trying to create a weekly reminder in my app. For this I am using AlarmManager.
Here is the code generating alarm
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);
This is the weekly remainder class which extends broadcast
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();
}
}
}
In androidmanifest.xml I have this entry before the tag
<receiver android:name="WeeklyReminder">
I want the reminder to be invoked even when the app is closed. But now nothing is happening
Is it the right way of doing it?
Thanks

我解决了这个问题，并将其提供给将来可能遇到同样问题的人。
在 androidmanifest 文件中我缺少“.”即我使用的是“WeeklyReminder”而不是“.WeeklyReminder”
所以正确的条目是
I resolved the issue and putting it for someone who may come across the same problem in future.
In androidmanifest file I was missing '.' ie instead of ".WeeklyReminder" I was using "WeeklyReminder"
So the correct entry is
