Open Instagram User Profile

Question

I managed to open the Twitter and Facebook user profile from my app. But I can not find any references to Instagram.

Is There a way to open Instagram in order to show a user profile like in twitter or facebook?

For instance, in order to get the Intent to launch the twitter application I do:

public Intent getOpenTwitterIntent(Context context) {

    try {
        return new Intent(Intent.ACTION_VIEW,
                Uri.parse("twitter://user?screen_name="
                        .concat(twitterUsername)));

    } catch (Exception e) {
        return new Intent(
                Intent.ACTION_VIEW,
                Uri.parse("https://twitter.com/#!/".concat(twitterUsername)));
    }

}

How can I achive something similar with Instagram? Thanks in advance.
