Open Facebook page from Android app?

问题


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?


回答1:


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);
}

This works on the latest version:

  1. Go to https://graph.facebook.com/<user_name_here> (https://graph.facebook.com/fsintents for instance)
  2. Copy your id

  3. Use this method:

    public static Intent getOpenFacebookIntent(Context context) {

   try {
    context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
    return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/<id_here>"));
   } catch (Exception e) {
    return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/<user_name_here>"));
   }
}

This will open the Facebook app if the user has it installed. Otherwise, it will open Facebook in the browser.

EDIT: since version 11.0.0.11.23 (3002850) Facebook App do not support this way anymore, there's another way, check the response below from Jared Rummler.

Is this not easier? For example within an onClickListener?

try {
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/426253597411506"));
    startActivity(intent);
} catch(Exception e) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.facebook.com/appetizerandroid")));
}

PS. Get your id (the large number) from http://graph.facebook.com/[userName]

For Facebook page:

try {
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://page/" + pageId));
} catch (Exception e) {
    intent =  new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + pageId));
}

For Facebook profile:

try {
    intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/" + profileId));
} catch (Exception e) {
    intent =  new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/" + profileId));
}

...because none of the answers points out the difference

Both tested with Facebook v.27.0.0.24.15 and Android 5.0.1 on Nexus 4

Here's the way to do it in 2016, works great, and is very easy.

I discovered this after looking into how emails send by facebook opened the app.

// e.g. if your URL is https://www.facebook.com/EXAMPLE_PAGE, you should put EXAMPLE_PAGE at the end of this URL, after the ?
String YourPageURL = "https://www.facebook.com/n/?YOUR_PAGE_NAME";
Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(YourPageURL));

startActivity(browserIntent);



回答6:


this is the simplest code for doing this

public final void launchFacebook() {
        final String urlFb = "fb://page/"+yourpageid;
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.setData(Uri.parse(urlFb));

        // If a Facebook app is installed, use it. Otherwise, launch
        // a browser
        final PackageManager packageManager = getPackageManager();
        List<ResolveInfo> list =
            packageManager.queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
        if (list.size() == 0) {
            final String urlBrowser = "https://www.facebook.com/pages/"+pageid;
            intent.setData(Uri.parse(urlBrowser));
        }

        startActivity(intent);
    }

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.

This has been reverse-engineered by Pierre87 on the FrAndroid forum, but I can't find anywhere official that describes it, so it's has to be treated as undocumented and liable to stop working at any moment:

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClassName("com.facebook.katana", "com.facebook.katana.ProfileTabHostActivity");
intent.putExtra("extra_user_id", "123456789l");
this.startActivity(intent);

            if (versionCode >= 3002850) {

        }



回答11:


To do this we need the "Facebook page id", you can get it :

  • from the page go to "About".
  • go to "More Info" section.

To opening facebook app on specified profile page,

you can do this:

 String facebookId = "fb://page/<Facebook Page ID>";
  startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId)));

Or you can validate when the facebook app is not installed, then open the facebook web page.

String facebookId = "fb://page/<Facebook Page ID>";
String urlPage = "http://www.facebook.com/mypage";

     try {
          startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(facebookId )));
        } catch (Exception e) {
         Log.e(TAG, "Application not intalled.");
         //Open url web page.
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse(url)));
        }

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));
    }
}



回答13:


My answer builds on top of the widely-accepted answer from joaomgcd. If the user has Facebook installed but disabled (for example by using App Quarantine), this method will not work. The intent for the Twitter app will be selected but it will not be able to process it as it is disabled.

Instead of:

context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));

You can use the following to decide what to do:

PackageInfo info = context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
if(info.applicationInfo.enabled)
    return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));
else
    return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/620681997952698"));

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);
}

Intent intent = null;
    try {
        getPackageManager().getPackageInfo("com.facebook.katana", 0);
        String url = "https://www.facebook.com/"+idFacebook;
        intent = new Intent(Intent.ACTION_VIEW, Uri.parse("fb://facewebmodal/f?href="+url));
    } catch (Exception e) {
        // no Facebook app, revert to browser
        String url = "https://facebook.com/"+idFacebook;
        intent = new Intent(Intent.ACTION_VIEW);
        intent .setData(Uri.parse(url));
    }
    this.startActivity(intent);

I have created a method to open facebook page into facebook app, if app is not existing then opening in chrome

    String socailLink="https://www.facebook.com/kfc";
    Intent intent = new Intent(Intent.ACTION_VIEW);
    String facebookUrl = Utils.getFacebookUrl(getActivity(), socailLink);
    if (facebookUrl == null || facebookUrl.length() == 0) {
        Log.d("facebook Url", " is coming as " + facebookUrl);
        return;
    }
    intent.setData(Uri.parse(facebookUrl));
    startActivity(intent);

Utils.class add these method 

public static String getFacebookUrl(FragmentActivity activity, String facebook_url) {

To launch facebook page from your app, let urlString = "fb://page/your_fb_page_id"

To launch facebook messenger let urlString = "fb-messenger://user/your_fb_page_id"

FB page id is usually numeric. To get it, goto Find My FB ID input your profile url, something like www.facebook.com/edgedevstudio then click "Find Numberic ID".

Voila, you now have your fb numeric id. replace "your_fb_page_id" with the generated Numeric ID

 val intent = Intent(Intent.ACTION_VIEW, Uri.parse(urlString))
 if (intent.resolveActivity(packageManager) != null) //check if app is available to handle the implicit intent
 startActivity(intent)

You can open the facebook app on button click as follows:-

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    this.findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            startNewActivity("com.facebook.katana");
        }
    });

}

public void startNewActivity( String packageName)
{
    Intent intent = MainActivity.this.getPackageManager().getLaunchIntentForPackage(packageName);
    if (intent != null)
    {
        // we found the activity
        // now start the activity
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
    else
    {
        // bring user to the market
        // or let them choose an app?
        intent = new Intent(Intent.ACTION_VIEW);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setData(Uri.parse("market://details?id="+packageName));
        startActivity(intent);
    }
}
