Question

I'm using Jelly Bean's rich notification system and I'm adding two actions to my notification. The problem I have is the actions seem to be disabled.

The idea is to set a PendingIntent to each one of the actions and get notified in a BroadcastReceiver which I registered to handle the actions in the two intents.

Here is the code for creating the notifications:

        Intent startIntent = new Intent(Notifications.START);
        Intent resetIntent = new Intent(Notifications.RESET);

        PendingIntent startPendingIntent = PendingIntent.getBroadcast(ctx,
                whichOne, startIntent,
                Intent.FLAG_RECEIVER_REPLACE_PENDING);
        PendingIntent resetPendingIntent = PendingIntent.getBroadcast(ctx,
                whichOne, resetIntent,
                Intent.FLAG_RECEIVER_REPLACE_PENDING);

        [...]

        notificationBuilder = new Notification.Builder(ctx)
                .setContentTitle(s)
                .setContentText("")
                .setContentIntent(appIntent)
                .setSmallIcon(R.drawable.ic_launcher)

                .addAction(R.drawable.play,
                        ctx.getString(R.string.START), startPendingIntent)
                .addAction(R.drawable.reload,
                        ctx.getString(R.string.RESET_TIMER),
                        resetPendingIntent);
        [...]

Then I register the Receiver like this:

IntentFilter filter = new IntentFilter();
    filter.addAction(Notifications.START);
    filter.addAction(Notifications.RESET);

    receiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            Toast.makeText(context, intent.getAction(), Toast.LENGTH_LONG)
                    .show();

        }
    };

    registerReceiver(receiver, filter);

The problem I have is the actions seems to be disabled. I cannot click them and they are displayed with the typical disabled alpha text color.

You should remove the Intent.FLAG_RECEIVER_REPLACE_PENDING flag from your PendingIntent for both actions and replace it with 0. That flag is most commonly used with sticky broadcasts where the most recent value is the only one that matters (eg checking battery level).

Removing that flag will re-enable your actions. If your intent was to only make one action available at any given time then I suggest using a static ID for that notification so that only one notification of that type can be used at any given time.
