NavUtils.navigateUpTo() does not start any Activity

Question

I have two activities

• MainActivity
• DeepLinkActivity

I set up everything to use the NavUtils for navi

Answer 1

My solution to OPs problem:

public void navigateUp() {
    final Intent upIntent = NavUtils.getParentActivityIntent(this);
    if (NavUtils.shouldUpRecreateTask(this, upIntent) || isTaskRoot()) {
        Log.v(logTag, "Recreate back stack");
        TaskStackBuilder.create(this).addNextIntentWithParentStack(upIntent).startActivities();
    } else {
        NavUtils.navigateUpTo(this, upIntent);
    }
}

isTaskRoot() will return true if DeepLinkActivity is the root of a task (initial launch of application or application was previously terminated through task manager). This way I'm not loosing existing back stack if activity was launched through link when applications task was already in the foreground.
