PendingIntent from second action overwrites the first action and the contentIntent for Notification

Question

The code:

int id = 0;
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
  .setContentTitle(context.getString(R.string.notification_on_the_move_gps_title))
  .setContentText(context.getString(R.string.notification_on_the_move_text));

builder.setStyle(new NotificationCompat.BigTextStyle().bigText(context.getString(R.string.notification_on_the_move_gps_big_text)));

Intent mainIntent = new Intent(context, MainActivity.class);

Intent turnOffIntent = new Intent(context, MainActivity.class);
turnOffIntent.putExtra(MainApp.KEY_TURN_OFF_NOTIFICATION_ID, id);

TaskStackBuilder mainBuilder = TaskStackBuilder.create(context);
mainBuilder.addParentStack(MainActivity.class);
mainBuilder.addNextIntent(mainIntent);
PendingIntent mainPendingIntent = mainBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(mainPendingIntent);

TaskStackBuilder turnOffBuilder = TaskStackBuilder.create(context);
turnOffBuilder.addParentStack(MainActivity.class);
turnOffBuilder.addNextIntent(turnOffIntent);
PendingIntent turnOffPendingIntent = turnOffBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);

builder
  .setSmallIcon(R.drawable.ic_stat_notification)
  .setLargeIcon(BitmapFactory.decodeResource(context.getResources(), R.drawable.ic_launcher))
  .setAutoCancel(true)
  .setLights(Color.BLUE, 500, 500)
  .setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
  .addAction(R.drawable.ic_stat_notification, "Open", mainPendingIntent)
  .addAction(R.drawable.ic_stat_notification_off, "Turn off", turnOffPendingIntent);

NotificationManager nm = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
nm.notify(id, builder.build());

The problem:

Clicking on the unexpanded or expanded notification body or on the Open action button always transfers the intent with (KEY_TURN_OFF_NOTIFICATION_ID) extra.

I've tried ditching the TaskStackBuilder and creating PendingIntents simply:

Intent mainIntent = new Intent(context, MainActivity.class);
PendingIntent piMain = PendingIntent.getActivity(context, 0, mainIntent, 0);

Intent turnOffIntent = new Intent(context, MainActivity.class);
turnOffIntent.putExtra(MainApp.KEY_TURN_OFF_NOTIFICATION_ID, id);
PendingIntent piTurnOff = PendingIntent.getActivity(context, 0, turnOffIntent, 0);

but, to same effect :(

If I ommit setContentIntent(), naturally, tapping on the notification body does nothing.

If I set setContentIntent() after setting actions, then the extra is never received in the MainActivity.

From the doc:

Because of this behavior, it is important to know when two Intents are considered to be the same for purposes of retrieving a PendingIntent. A common mistake people make is to create multiple PendingIntent objects with Intents that only vary in their "extra" contents, expecting to get a different PendingIntent each time. This does not happen. The parts of the Intent that are used for matching are the same ones defined by Intent.filterEquals. If you use two Intent objects that are equivalent as per Intent.filterEquals, then you will get the same PendingIntent for both of them.

So you have to make those intents different as in Intent.filterEquals method:

That is, if their action, data, type, class, and categories are the same. This does not compare any extra data included in the intents.

As a side note, I had the same problem while working on the download notifications of firefox for android here
