TaskStackBuilder and extras for the back stack

This line:

sBuilder.addParentStack( ActivityC.class );

adds all parents declared for ActivityC in AndroidManifest.xml in <meta-data>. I don’t know what it is, I haven’t used it. I doubt you need it.

This line adds intent to an array:

sBuilder.addNextIntent(launchIntent);

then the array of intents is used to create PendingIntent, probably with PendingIntent.getActivities, I couldn’t find the implementation, which is then started somewhere with Context.startActivities.

I think you just need to create set of intents, there you can add extras:

Intent activityA = new Intent(context, ActivityA.class);
activityA.putExtra(key, valueA);
Intent activityB = new Intent(context, ActivityB.class);
activityB.putExtra(key, valueB);
Intent activityC = new Intent(context, ActivityC.class);
activityC.putExtra(key, valueC);

and add them to builder:

sBuilder.addNextIntent(activityA);
sBuilder.addNextIntent(activityB);
sBuilder.addNextIntent(activityC);
pIntent = sBuilder.getPendingIntent( 0, PendingIntent.FLAG_ONE_SHOT );

I haven’t tested it, this is only a result of my fast research, I hope someone will correct me if I’m wrong.
