无法检索相同的挂起意图。

Question

即使传递了相同的意图ID，我也无法检索相同的意图。

我已检查广播接收器在创建待定意图时使用的上下文是否完全相同。

public class AlarmReceiver extends BroadcastReceiver {

public static String NOTIFICATION_ID = "notification-id";
public static String NOTIFICATION = "notification";
public static MediaPlayer mMediaPlayer;
public static NotificationManager notificationManager;
public static Notification notification;
public static int id;
Context ctx;

@Override
public void onReceive(final Context context, Intent intent) {
    ctx = context;

    Log.d("WTF", ""+intent.getAction());

    if (intent.getAction() != null) {
        String action = intent.getAction();
        switch (action) {
            case "SNOOZE":
                Log.v("shuffTest", "Pressed Snoozed");
                break;
            case "STOP_ACTION":
                Log.v("shuffTest", "Pressed Stop");
                mMediaPlayer.stop();
                notificationManager.cancel(id);
                stopReceiverServices();
                break;
        }
    } else {
        notificationManager = (NotificationManager) context.getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = intent.getParcelableExtra(NOTIFICATION);
        id = intent.getIntExtra(NOTIFICATION_ID, 0);
        notificationManager.notify(id, notification);
        playAlarmSound();
    }

    // This is the Intent to deliver to our service.
    //Intent service = new Intent(context, SimpleWakefulService.class);
    // Start the service, keeping the device awake while it is launching.
    //startWakefulService(context, service)
}

public void stopReceiverServices(){
    Intent notificationIntent = new Intent(ctx.getApplicationContext(), AlarmReceiver.class);
    notificationIntent.putExtra(AlarmReceiver.NOTIFICATION_ID, 123);
    notificationIntent.putExtra(AlarmReceiver.NOTIFICATION, notification);
    Log.d("TAG", "Context A1: "+ctx.getApplicationContext().toString());
    Log.d("TAG", "Context A2: "+ctx.toString());
    AlarmManager alarmManager = (AlarmManager) ctx.getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    Log.d("TAG", "AlarmManager Before: " + alarmManager);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx.getApplicationContext(), 987654321, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    Log.d("TAG", "PendingIntent Before: " + pendingIntent);
    alarmManager.cancel(pendingIntent);
    pendingIntent.cancel();
    Log.d("TAG", "AlarmManager After: " + alarmManager);
    Log.d("TAG", "PendingIntent After: " + pendingIntent);
}
/..
}

创建PendingEvent时。

void setAlarm(Context context) {
    mContext = context;
    Intent notificationIntent = new Intent(context, AlarmReceiver.class);
    notificationIntent.putExtra(AlarmReceiver.NOTIFICATION_ID, 123);
    notificationIntent.putExtra(AlarmReceiver.NOTIFICATION, getNotification("Wake Up! Wake Up"));

    AlarmManager alarmManager = (AlarmManager) context.getApplicationContext().getSystemService(Context.ALARM_SERVICE);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context.getApplicationContext(), 987654321, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

    Calendar calendar = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
    calendar.set(Calendar.MINUTE, minuteOfHour);

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

    Log.d("TAG", "AlarmManager After setting : " + alarmManager);
    Log.d("TAG", "PendingIntent After setting : " + pendingIntent);

    Log.d("Ctx setAlarm1 ", context.getApplicationContext().toString());
}

Answer 1

在alarmManager和PendingEvent中删除GetApplicationNext（）

void setAlarm(Context context) {

...

AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context), 987654321, notificationIntent, PendingIntent.FLAG_UPDATE_CURRENT);

...
}
