Not able to get serialized bundle in an activity

Question

I have a class public class Alarm implements Serializable. This has a method in it:

public void schedule(Context context) {
    setAlarmActive(true);

    Intent myIntent = new Intent(context, AlarmAlertBroadcastReciever.class);

    Bundle bundle = new Bundle();
    bundle.putSerializable("alarm", this);
    myIntent.putExtras(bundle);
    //myIntent.putExtra("alarm", this);

    Alarm alarm = (Alarm) bundle.getSerializable("alarm");

    if(alarm !=null){
        Log.d("Alarmdebug", "alatm is not null");
    }

    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, myIntent,PendingIntent.FLAG_CANCEL_CURRENT);

    AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

    alarmManager.set(AlarmManager.RTC_WAKEUP, getAlarmTime().getTimeInMillis(), pendingIntent);                 
}

Elsewhere I have this code. Which is not able to get the serialized extras. This is invoked but alarm is always null.

    Bundle bundle = intent.getExtras();

    final Alarm alarm = (Alarm) bundle.getSerializable("alarm");

    if(alarm==null){
        Log.d("Alarmdebug", "alarm is null 2");
    }

Can you please tell me what is the issue with this code? I tried the solution here: Passing data through intent using Serializable but it doesn't work for me.

Thank you

EDIT

Anyone looking for the solution can find it below now.

It seems serialized bundles don't work on some devices. Had to to byte[]

Answer is here:

Pass Serializable Object to Pending Intent

Send it like this:

//AlarmService.java
Intent myIntent = new Intent(getApplicationContext(), AlarmAlertBroadcastReciever.class);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
ObjectOutputStream out = null;
try {
    out = new ObjectOutputStream(bos);
    out.writeObject(alarm);
    out.flush();
    byte[] data = bos.toByteArray();
    myIntent.putExtra("alarm", data);
} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        bos.close();
    } catch (IOException ex) {
        ex.printStackTrace();
    }
}

PendingIntent pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, myIntent, PendingIntent.FLAG_CANCEL_CURRENT);

AlarmManager alarmManager = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmManager.set(AlarmManager.RTC_WAKEUP, alarm.getAlarmTime().getTimeInMillis(), pendingIntent);

Receive it like this:

//AlarmAlertBroadcastReceiver.java

@Override
public void onReceive(Context context, Intent intent) {
   ByteArrayInputStream bis = new ByteArrayInputStream(intent.getByteArrayExtra("alarm"));
    ObjectInput in = null;
    Alarm alarm = null;
    try {
        in = new ObjectInputStream(bis);
        alarm = (Alarm)in.readObject();
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            if (in != null) {
                in.close();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}
