Open facebook page from android app (in facebook version > v11)

In Facebook version 11.0.0.11.23 (3002850) fb://profile/ and fb://page/ are no longer supported. I decompiled the Facebook app and was able to come up with the following solution:

java

String facebookUrl = "https://www.facebook.com/JRummyApps";
try {
    int versionCode = getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;
    if (versionCode >= 3002850) {
        Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, uri));;
    } else {
        // open the Facebook app using the old method (fb://profile/id or fb://page/id)
        startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/336227679757310")));
    }
} catch (PackageManager.NameNotFoundException e) {
    // Facebook is not installed. Open the browser
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookUrl)));
}

Edit: It has been some time and it looks like fb://profile and fb://page are no longer supported. Below is the method I have been using in production:

java

/**
 * Intent to open the official Facebook app. If the Facebook app is not installed then the
 * default web browser will be used.</p>
 * 
 * Example usage:</p>
 * <code>newFacebookIntent(context.getPackageManager(), "https://www.facebook.com/JRummyApps");</code></p>
 * 
 * @param pm
 *            Instance of the {@link PackageManager}.
 * @param url
 *            The full URL to the Facebook page or profile.
 * @return An intent that will open the Facebook page/profile.
 */
public static Intent newFacebookIntent(PackageManager pm, String url) {
    Uri uri;
    try {
        pm.getPackageInfo("com.facebook.katana", 0);
        // http://stackoverflow.com/a/24547437/1048340
        uri = Uri.parse("fb://facewebmodal/f?href=" + url);
    } catch (PackageManager.NameNotFoundException e) {
        uri = Uri.parse(url);
    }
    return new Intent(Intent.ACTION_VIEW, uri);
}
