我正在尝试使用以下 SO 示例中的代码设置重复发生的警报示例：
但是，我收到一条错误消息，指出“无法将上下文解析为变量”：
PendingIntent pi = PendingIntent.getBroadcast(context, 0, Aintent, 0);
有什么建议么？
public class Alarm extends Service {
// compat to support older devices
@Override
public void onStart(Intent intent, int startId) {
onStartCommand(intent, 0, startId);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
// method to check if an alarm must be fired today
String alarm = Context.ALARM_SERVICE;
AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Calendar calendar = Calendar.getInstance();
calendar = Calendar.getInstance();
calendar.set(Calendar.DAY_OF_WEEK, 5);
calendar.set(Calendar.HOUR_OF_DAY, 23);
calendar.set(Calendar.MINUTE, 0);
calendar.set(Calendar.SECOND, 0);
Intent Aintent = new Intent("REFRESH_THIS");
PendingIntent pi = PendingIntent.getBroadcast(context, 0, Aintent, 0);
am.setRepeating(AlarmManager.RTC_WAKEUP,calendar.getTimeInMillis() , AlarmManager.INTERVAL_DAY, pi);
// reschedule to check again tomorrow
Intent serviceIntent = new Intent(Alarm.this, Alarm.class);
PendingIntent restartServiceIntent = PendingIntent.getService(
Alarm.this, 0, serviceIntent, 0);
AlarmManager alarms = (AlarmManager) getSystemService(ALARM_SERVICE);
// cancel previous alarm
alarms.cancel(restartServiceIntent);
// schedule alarm for today + 1 day
// Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.DATE, 1);
// schedule the alarm
alarms.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
restartServiceIntent);
}
@Override
public void onCreate() {

@Override

@Override
