Add facebook app to android

Getting Started with the Facebook SDK for Android

This documentation explains how to get started integrating your Android app with Facebook by using the Facebook SDK for Android. The current version of the Facebook SDK for Android is version 12.0.0 and requires the Android API 15. For more information about versions and features, see Facebook SDK for Android.

Beginning with SDK v13.0, set to release in early 2022, a Client Token will be required for all calls to the Graph API.

You can set up your app to use the Facebook SDK for Android in the following ways:

• By using the Quick Start.
• By setting up your project with the Facebook SDK for Android.

Quick Start

To get a Facebook App ID, configure your app’s settings, and import the Facebook SDK for Android, click on the button below and follow the instructions.

Android Studio Setup

To use the Facebook SDK in an Android Studio project, add the SDK as a build dependency and import the SDK.

1. Go to Android Studio | New Project | Minimum SDK.
2. Select API 15: Android 4.0.3 (IceCreamSandwich) or higher and create your new project.
3. After you create a new project, open Gradle Scripts | build.gradle (Project: and do the following:
   1. Add the following to the buildscript < repositories <>> section of the build.gradle (Project) file:
   2. Save and close build.gradle (Project: ) .
4. Open Gradle Scripts | build.gradle (Module: app) and do the following:
   1. Add the following to the dependencies <> section of your build.gradle (module: app) file to compile the latest version of the Facebook SDK for Android:

      When you use the Facebook SDK, some events in your app are automatically logged and collected unless you disable automatic event logging. For details about what information is collected and how to disable automatic event logging, see Automatic App Event Logging.

      Add Your Facebook App ID and Client Token

      Add your Facebook App ID and Client Token to your project’s strings file and update your Android manifest:

      1. Open your /app/res/values/strings.xml file.

      2. Add a string element with the name attribute facebook_app_id and value as your Facebook App ID to the file. For example

      3. Open /app/manifests/AndroidManifest.xml

      4. Add a uses-permission element to the manifest:

      5. Add a meta-data element to the application element:

      Sending Images or Videos

      If you’re sharing links, images or video via the Facebook for Android app, you also need to declare the FacebookContentProvider in the manifest.

      Append your app id to the end of the authorities value. For example if your Facebook app id is 1234 , the declaration looks like:

      Running Sample Apps

      The following samples come with the Facebook SDK for Android:

      • HelloFacebookSample — Demonstrates profile access, status updates and photo upload.
      • RPSSample — Use Native Share Dialog, Open Graph publishing, pickers, invites, and deep linking.
      • Scrumptious — Login, requests, pickers, picture uploads, and Open Graph publishing.

      You can experiment with samples by importing the Facebook SDK into an Android Studio project. The samples have a project dependency rather than a central repository dependency via maven central or jcenter. This is so that when a local copy of the SDK gets updates, the samples reflect the changes.

      To run samples apps quickly, you can generate key hashes for your development environments. Add these to your Facebook developer profile for the sample apps. Keytool, for generating the key hashes, is included with the Java SE Development Kit (JDK) that you installed as part of setting up your development environment. OpenSSL is available for download from OpenSSL.

      On Windows, you need the following:

      Run the following command in a command prompt in the Java SDK folder. This generates a 28 character string.

      Go to the Facebook Developer site. Log into Facebook and, using the dropdown menu in the top-right, go to Developer Settings:

      

      In your developer settings, select Sample App from the menu, and add and save your key hash into your profile:

      

      You can add multiple key hashes if you develop with multiple machines.

      You can now compile and run all of the samples — including those that use Facebook Login.

      Create a Development Key Hash

      Facebook uses the key hash to authenticate interactions between your app and the Facebook app. If you run apps that use Facebook Login, you need to add your Android development key hash to your Facebook developer profile.

      For the version of your app that you release to you also need to generate and set a Release Key Hash.

      On either OS X or Windows you can get a key hash by generating it or by using the value returned by Settings.getApplicationSignature(Context) . For instructions, see Running Sample Apps .

      Create a Release Key Hash

      To authenticate the exchange of information between your app and the Facebook, you need to generate a release key hash and add this to the Android settings within your Facebook App ID. Without this, your Facebook integration may not work properly when you release your app to the store.

      In a previous step, you should have updated your Facebook Developer Settings with the key hashes for your development environments.

      When publishing your app, it is typically signed with a different signature to your development environment. Therefore, you want to make sure you create a Release Key Hash and add this to the Android settings for Facebook App ID.

      To generate a hash of your release key, run the following command on Mac or Windows substituting your release key alias and the path to your keystore.

      On Windows, you need the following:

      Run the following command in a command prompt in the Java SDK folder:

      Make sure to use the password that you set when you first created the release key.

      This command should generate a 28 characher string. Copy and paste this Release Key Hash into your Facebook App ID’s Android settings.

      

      You should also check that your Facebook App ID’s Android setting also contain the correct package name and main activity class for your Android package.

      Use the Facebook SDK for Android with Maven

      You can declare the Maven dependency with the latest available version of the Facebook SDK for Android.

      Troubleshooting Sample Apps

      If you have a problem running a sample app, it may be related to the key hash. You may see one of the following scenarios:

      • A native Login Dialog appears but after accepting the permissions you are still in a logged out state. The logcat also contains an exception:
      • A non-native Login Dialog appears with an error message: »..App is Misconfigured for facebook login. ».

      Check your key hash and you can make sure you use the correct key hash. I

      You can also manually modify the sample code to use the right key hash. For example in HelloFacebookSampleActivity class make a temporary change to the onCreate() :

      Save your changes and re-run the sample. Check your logcat output for a message similar to this:

      Save the key hash in your developer profile. Re-run the samples and verify that you can log in successfully.

      Getting started with the Facebook for Android SDK

      

      Many mobile apps allow the user to post content to popular social media platforms, such as Facebook, Twitter and LinkedIn.

      This kind of social sharing can be a great way to promote your app, and can improve the user experience by creating a connection between your application and the user’s favorite social media networks.

      To promote social sharing, many of the major social platforms have created tools that specifically target app developers – and Facebook is no exception!

      In this article, I’ll show you how to add Facebook integration to your Android applications, using the Facebook for Android SDK (Software Development Kit). Once you’re connected to the official Facebook SDK, you’ll have access to a wide range of features, but in this article we’ll be focusing on two of the most popular: authenticating with Facebook, and social sharing.

      By the end of this article, you’ll have created an application that allows users to authenticate their identify using their Facebook credentials, and then share your app’s content, by posting it to Facebook.

      

      What is the Facebook for Android SDK?

      Every social media platform wants to drive user engagement, and enabling users to share content from a range of sources is a powerful way to keep them engaged with your platform.

      The official Facebook SDK for Android helps you create apps that integrate with Facebook, and provides access to several key features, including Facebook authentication, and reading and writing to the platform’s APIs.

      The Facebook SDK for Android compromises of the following components:

      • Analytics. Provides access to aggregated and anonymized data, so you can analyze how people are using your app.
      • Login. Allows people to sign into your app using their Facebook credentials. If the user is already signed into the Facebook for Android mobile app, then they won’t have to re-enter their username and password, in order to authenticate with your application. Once a user is signed in with Facebook, you can retrieve information and perform actions on their behalf, such as displaying their Facebook profile pic inside your app, or posting status updates.
      • Account Kit. Makes it possible for users to authenticate their identify, using just their phone number or email address. Account Kit doesn’t require a Facebook account, which makes this a viable authentication method for any users who haven’t signed up to Facebook.
      • Ads. If you want to monetize your application, then you can use this component to create and run ad campaigns.
      • App events. Allows you to track a range of user actions and events within your app. You can use this information to evaluate the effectiveness of your Mobile App Ads, or to identify the users who are most likely to respond to your adverts.
      • App Links. Imagine a user has just posted some of your app’s content to Facebook; App Links let you specify what happens, when someone interacts with this content. For example, they might get forwarded to your app’s Google Play listing, or your company’s website. Alternatively, if someone already has your app installed on their device, then you may respond by launching your application, and taking them to an Activity related to this content.
      • Graph API. By integrating with the Facebook Graph API, you can retrieve data from the Facebook platform, and add data such as posting new stories and uploading photos.

      What are the benefits of Facebook integration?

      For developers, the Facebook for Android SDK has several benefits.

      1. Seamless sign up

      Depending on your application, users may need to authenticate their identity before they can access certain features. Even if your application only requires an email address and password, there’s always going to be a percentage of mobile users who decide this is too much hassle, and exit your application.

      There’s several reasons why we’re much less likely to complete a registration form on a mobile device, compared to our laptop or computer. Firstly, we tend to use smartphones and tablets on the go, and often under time constraints, for example you might spend a few minutes playing on your phone while you’re waiting at the doctor’s office, in line at the supermarket, or at your local bus stop. None of these scenarios are ideal for completing an in-app form!

      In addition, typing on your mobile device’s small, virtual keyboard can be time-consuming and frustrating, particularly for users who have manual dexterity issues, or anyone who’s prone to typos. Typing a password that contains a mixture of symbols, numbers, and upper and lowercase letters, can feel like a huge effort on your smartphone or tablet.

      By adding Facebook login to your application, you can replace an in-app registration form, with single-tap authentication.
