Open Facebook page from Android app?

2018-12-31 09:44发布

from my Android app, I would like to open a link to a Facebook profile in the official Facebook app (if the app is installed, of course). For iPhone, there exists the fb:// URL scheme, but trying the same thing on my Android device throws an ActivityNotFoundException.

Is there a chance to open a Facebook profile in the official Facebook app from code?

A more reusable approach.

This is a functionality we generally use in most of our apps. Hence here is a reusable piece of code to achieve this.

(Similar to other answers in terms for facts. Posting it here just to simplify and make the implementation reusable)

"fb://page/ does not work with newer versions of the FB app. You should use fb://facewebmodal/f?href= for newer versions. (Like mentioned in another answer here)

This is a full fledged working code currently live in one of my apps:

public static String FACEBOOK_URL = "https://www.facebook.com/YourPageName";
public static String FACEBOOK_PAGE_ID = "YourPageName";

//method to get the right URL to use in the intent
public String getFacebookPageURL(Context context) {
        PackageManager packageManager = context.getPackageManager();
        try {
            int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;
            if (versionCode >= 3002850) { //newer versions of fb app
                return "fb://facewebmodal/f?href=" + FACEBOOK_URL;
            } else { //older versions of fb app
                return "fb://page/" + FACEBOOK_PAGE_ID;
            }
        } catch (PackageManager.NameNotFoundException e) {
            return FACEBOOK_URL; //normal web url
        }
    }

This method will return the correct url for app if installed or web url if app is not installed.

Then start an intent as follows:

Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
String facebookUrl = getFacebookPageURL(this);
facebookIntent.setData(Uri.parse(facebookUrl));
startActivity(facebookIntent);

That's all you need.

try this code:

String facebookUrl = "https://www.facebook.com/<id_here>";
        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 {
                Uri uri = Uri.parse("fb://page/<id_here>");
                startActivity(new Intent(Intent.ACTION_VIEW, uri));
            }
        } catch (PackageManager.NameNotFoundException e) {
            startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookUrl)));
        }

In Facebook version 11.0.0.11.23 (3002850) fb://profile/ and fb://page/ no longer work. I decompiled the Facebook app and found that you can use fb://facewebmodal/f?href=[YOUR_FACEBOOK_PAGE]. Here is the method I have been using in production:

/**
 * <p>Intent to open the official Facebook app. If the Facebook app is not installed then the
 * default web browser will be used.</p>
 *
 * <p>Example usage:</p>
 *
 * {@code newFacebookIntent(ctx.getPackageManager(), "https://www.facebook.com/JRummyApps");}
 *
 * @param pm
 *     The {@link PackageManager}. You can find this class through {@link
 *     Context#getPackageManager()}.
 * @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 = Uri.parse(url);
  try {
    ApplicationInfo applicationInfo = pm.getApplicationInfo("com.facebook.katana", 0);
    if (applicationInfo.enabled) {
      // http://stackoverflow.com/a/24547437/1048340
      uri = Uri.parse("fb://facewebmodal/f?href=" + url);
    }
  } catch (PackageManager.NameNotFoundException ignored) {
  }
  return new Intent(Intent.ACTION_VIEW, uri);
}

After much testing I have found one of the most effective solutions:

private void openFacebookApp() {
    String facebookUrl = "www.facebook.com/XXXXXXXXXX";
    String facebookID = "XXXXXXXXX";

    try {
        int versionCode = getActivity().getApplicationContext().getPackageManager().getPackageInfo("com.facebook.katana", 0).versionCode;

        if(!facebookID.isEmpty()) {
            // open the Facebook app using facebookID (fb://profile/facebookID or fb://page/facebookID)
            Uri uri = Uri.parse("fb://page/" + facebookID);
            startActivity(new Intent(Intent.ACTION_VIEW, uri));
        } else if (versionCode >= 3002850 && !facebookUrl.isEmpty()) {
            // open Facebook app using facebook url
            Uri uri = Uri.parse("fb://facewebmodal/f?href=" + facebookUrl);
            startActivity(new Intent(Intent.ACTION_VIEW, uri));
        } else {
            // Facebook is not installed. Open the browser
            Uri uri = Uri.parse(facebookUrl);
            startActivity(new Intent(Intent.ACTION_VIEW, uri));
        }
    } catch (PackageManager.NameNotFoundException e) {
        // Facebook is not installed. Open the browser
        Uri uri = Uri.parse(facebookUrl);
        startActivity(new Intent(Intent.ACTION_VIEW, uri));
    }
}

Best answer I have found, it's working great.

Just go to your page on Facebook in the browser, right click, and click on "View source code", then find the page_id attribute: you have to use page_id here in this line after the last back-slash:

fb://page/pageID

For example:

Intent facebookAppIntent;
try {
    facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/1883727135173361"));
    startActivity(facebookAppIntent);
} catch (ActivityNotFoundException e) {
    facebookAppIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://facebook.com/CryOut-RadioTv-1883727135173361"));
    startActivity(facebookAppIntent);
}

As of July 2018 this works perfectly with or without the Facebook app on all the devices.

private void goToFacebook() {
    try {
        String facebookUrl = getFacebookPageURL();
        Intent facebookIntent = new Intent(Intent.ACTION_VIEW);
        facebookIntent.setData(Uri.parse(facebookUrl));
        startActivity(facebookIntent);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

private String getFacebookPageURL() {
    String FACEBOOK_URL = "https://www.facebook.com/Yourpage-1548219792xxxxxx/";
    String facebookurl = null;

    try {
        PackageManager packageManager = getPackageManager();

        if (packageManager != null) {
            Intent activated = packageManager.getLaunchIntentForPackage("com.facebook.katana");

            if (activated != null) {
                int versionCode = packageManager.getPackageInfo("com.facebook.katana", 0).versionCode;

                if (versionCode >= 3002850) {
                    facebookurl = "fb://page/1548219792xxxxxx";
                }
            } else {
                facebookurl = FACEBOOK_URL;
            }
        } else {
            facebookurl = FACEBOOK_URL;
        }
    } catch (Exception e) {
        facebookurl = FACEBOOK_URL;
    }
    return facebookurl;
}
