• Add apply plugin: 'com.google.gms.google-services' in your app level build.gradle

3. Twitter

<meta-data android:name="io.fabric.ApiKey"
				android:value="@string/fabric_api"
				/>

• Add these lines build.gradle at App level

buildscript {
  repositories {
    maven { url 'https://maven.fabric.io/public' }
  }

  dependencies {
    classpath 'io.fabric.tools:gradle:1.+'

  }
}

repositories {
  maven { url 'https://maven.fabric.io/public' }
}
buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'me.tatarka:gradle-retrolambda:3.5.0'
  }
}

repositories {
  mavenCentral()
}

apply plugin: 'io.fabric'
apply plugin: 'me.tatarka.retrolambda'
 
android {
  compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
  }
}

Step 2:

• Intialise the Login Manager in Application Class.

public class App extends Application {

  @Override public void onCreate () {
    super.onCreate ();
    LoginManager.init (this);
  }
}

Step 3:

• Add the following code to Activity to which you want to use.

public class LoginManagerActivity extends Activity {
 
  String TAG = LoginManagerActivity.class.getName ();

  @Override protected void onCreate (Bundle savedInstanceState) {
    super.onCreate (savedInstanceState);
    setContentView (R.layout.activity_login_manager);
    findViewById (R.id.tv_facebook).setOnClickListener (new View.OnClickListener () {
      @Override public void onClick (View v) {
        loginFacebook();
      }
    });
    findViewById (R.id.tv_google_plus).setOnClickListener (new View.OnClickListener () {
      @Override public void onClick (View v) {
        loginGooglePlus();
      }
    });

    findViewById (R.id.tv_twitter).setOnClickListener (new View.OnClickListener () {
      @Override public void onClick (View v) {
        loginTwitter ();
      }
    });

  }

  private void loginFacebook(){

    try {
      LoginManager.getInstance (this)
          .choose (Platforms.FACEBOOK)
          .login ()
          .subscribe (socialUser -> {
            Intent intent = new Intent (LoginManagerActivity.this,InfoActivity.class);
            intent.putExtra ("name",socialUser.getFullName ());
            intent.putExtra ("profile_url",socialUser.getUserProfileUrl ());
            startActivity (intent);

          }, error -> {
            Log.d (TAG, "error: " + error.getMessage ());
          });
    }catch (SocialPlatformNotFound spf){
      spf.printStackTrace ();
    }

  }

  private void loginGooglePlus(){
    try {
      LoginManager.getInstance (this)
          .choose (Platforms.GOOGLE_PLUS)
          .setClientId (getString (R.string.google_app_id))
          .login ()
          .subscribe (socialUser -> {
            Intent intent = new Intent (LoginManagerActivity.this,InfoActivity.class);
            intent.putExtra ("name",socialUser.getFullName ());
            intent.putExtra ("profile_url",socialUser.getUserProfileUrl ());
            startActivity (intent);
          }, error -> {
            Log.d (TAG, "error: " + error.getMessage ());
          });
    }catch (SocialPlatformNotFound spf){
      spf.printStackTrace ();
    }
  }

  private void loginTwitter(){

    try {
      LoginManager.getInstance (this)
          .choose (Platforms.TWITTER)
          .setClientId (getString (R.string.twitter_public))
          .setClientSecretId (getString (R.string.twitter_secret))
          .login ()
          .subscribe (socialUser -> {
            Intent intent = new Intent (LoginManagerActivity.this,InfoActivity.class);
            intent.putExtra ("name",socialUser.getFullName ());
            intent.putExtra ("profile_url",socialUser.getUserProfileUrl ());
            startActivity (intent);
          }, error -> {
            Log.d (TAG, "error: " + error.getMessage ());
          });
