For situations where you don't want / can't hard code the launcher activity this solution works

Intent i = getPackageManager()
    .getLaunchIntentForPackage(getPackageName())
    .setPackage(null)
    .setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);

PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, i, 0);

return new NotificationCompat.Builder(context)
        ...
        .setContentIntent(pendingIntent)
        .build();

The setPackage(null) part was key in my case since without it the app did not resume to previous task. I compared my intent with the intent from the Android launcher and noticed that pkg was not set there so that's how I came up with removing package name from the intent.

My particular situation was that the notification was created in a library so there I could not know what the launcher activity would be.
