Taskstackbuilder for api 14

My compiler is showing this message ...

Requires API API level 16 (current minimum is 14)

Question: "Does this code work fine in api 14 or not?" because I don't have a device to test this version of the API, because the AVD has no GPS (Requirement) Should I implement a support library or not?

Note

It works fine on API 16 and up

TaskStackBuilder

    PendingIntent contentIntent = TaskStackBuilder.create(this)
            // add all of DetailsActivity parents to the stack,
            // followed by DetailsActivity itself
            .addParentStack(Activity_TrackingMode.class)
            .addNextIntent(new Intent(this, Activity_TrackingMode.class))
            .getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
