Solution 1

This might help you

// Custom button
private Button fbbutton;

// Creating Facebook CallbackManager Value
public static CallbackManager callbackmanager;

@Override
protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Initialize SDK before setContentView(Layout ID)
    FacebookSdk.sdkInitialize(getApplicationContext());

    setContentView(R.layout.activity_main);

    // Initialize layout button
    fbbutton = (Button) findViewById(R.id.button2);

    fbbutton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // Call private method
            onFblogin();
        }
    });

}

// Private method to handle Facebook login and callback
private void onFblogin()
{
    callbackmanager = CallbackManager.Factory.create();

    // Set permissions 
    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("email","user_photos","public_profile"));

    LoginManager.getInstance().registerCallback(callbackmanager,
            new FacebookCallback<LoginResult>() {
                @Override
                public void onSuccess(LoginResult loginResult) {

                    System.out.println("Success");
                    GraphRequest.newMeRequest(
                            loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
                                @Override
                                public void onCompleted(JSONObject json, GraphResponse response) {
                                    if (response.getError() != null) {
                                        // handle error
                                        System.out.println("ERROR");
                                    } else {
                                        System.out.println("Success");
                                        try {

                                            String jsonresult = String.valueOf(json);
                                            System.out.println("JSON Result"+jsonresult);

                                            String str_email = json.getString("email");
                                            String str_id = json.getString("id");
                                            String str_firstname = json.getString("first_name");
                                            String str_lastname = json.getString("last_name");

                                        } catch (JSONException e) {
                                            e.printStackTrace();
                                        }
                                    }
                                }

                            }).executeAsync();

                }

                @Override
                public void onCancel() {
                    Log.d(TAG_CANCEL,"On cancel");
                }

                @Override
                public void onError(FacebookException error) { 
                    Log.d(TAG_ERROR,error.toString());
                }
    });
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    callbackmanager.onActivityResult(requestCode, resultCode, data);
}

In manifest add following,

<application
    android:allowBackup="true"
    android:icon="@drawable/app_icon"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    .
    .
     <!-- [START Facebook] -->
    <activity
        android:name="com.facebook.FacebookActivity"
        android:configChanges="keyboard|keyboardHidden|screenLayout|screenSize|orientation"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />

    <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/facebook_app_id" />
    <!-- [END Facebook] -->
    .
    .
</application>

Solution 2

The best solution is to log in by using LoginManager. Here is how I managed this ( on click is made with ButterKnife ):

 @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        
    mCallbackManager = CallbackManager.Factory.create();
}

@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);
    LoginManager.getInstance().registerCallback(mCallbackManager, this);
}

@OnClick(R.id.facebook_login_button)
@SuppressWarnings("unused")
public void loginWithFacebookAccount() {
    LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile", "email"));
}

@Override
public void onSuccess(LoginResult loginResult) {
    Bundle parameters = new Bundle();
    parameters.putString("fields", "id,name,last_name,link,email,picture");
    GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), (jsonObject, graphResponse) -> {
        String id = null;
        if (jsonObject != null) {
            try {
                id = jsonObject.getString("id");
            } catch (JSONException e) {
                e.printStackTrace();
            }                
        }
    });
    request.setParameters(parameters);
    request.executeAsync();
}

@Override
public void onCancel() {

}

@Override
public void onError(FacebookException e) {
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == Activity.RESULT_OK) {
        mCallbackManager.onActivityResult(requestCode, resultCode, data);           
    }
}

So this is how I've made it. Feel free to ask ;)

Solution 3

public class AuthWFacebookSDKFour extends Activity implements View.OnClickListener,FacebookCallback<LoginResult>   {

    List<String> permissionNeeds=Arrays.asList("user_photos","friends_photos", "email", "user_birthday", "user_friends");

    //facebook callbacks manager
    private CallbackManager cm;
    private LoginButton mFbLoginButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        //init facebook sdk and 
        FacebookSdk.sdkInitialize(getApplicationContext());

        //instantiate callbacks manager
        mCallbackManager = CallbackManager.Factory.create();


        mFbLoginButton=(LoginButton)findViewById(R.id.FBBUTTONID);

        //set permissions mFbLoginButton.setReadPermissions(ApplicationContext.facebookPermissions);
        // register callback
        //means hey facebook after login call onActivityResult of **this**  
        mFbLoginButton.registerCallback(mCallbackManager, this);

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {

        super.onActivityResult(requestCode, resultCode, data);
        //manage login result
        mCallbackManager.onActivityResult(requestCode, resultCode, data);
    }


    @Override
    public void onSuccess(LoginResult loginResults) {


        //login ok  get access token 
        AccessToken.getActiveAccessToken();   

    }
    @Override
    public void onCancel() {

        Log.e(TAG(),"facebook login canceled");

    }


    @Override
    public void onError(FacebookException e) {



        Log.e(TAG(),"facebook login failed error");

    }






}

remember to insert in manifest

<activity
 android:name="com.facebook.FacebookActivity"
 android:label="@string/app_name"
 android:theme="@android:style/Theme.Translucent.NoTitleBar"
                />

Solution 4

For Facebook SDK version 4.X, In your activity or fragment (generally on onCreate() method):

// Initialize Facebook Sdk before UI
    FacebookSdk.sdkInitialize(getApplicationContext());

    callbackManager = CallbackManager.Factory.create();
    loginButton = (LoginButton) findViewById(R.id.login_button);
    loginButton.setReadPermissions("user_friends");

    // Callback registration
    loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            // App code
            Log.v(TAG, "fblogin onSuccess");

        }

        @Override
        public void onCancel() {
            // App code
            Log.v(TAG, "fblogin onCancel");
        }

        @Override
        public void onError(FacebookException exception) {
            // App code
            Log.v(TAG, "fblogin onError");
        }
    });

And also dont forget to pass facebook activity result to manager:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    ...

    callbackManager.onActivityResult(requestCode, resultCode, data);
}

Solution 5

Using Android facebook SDK 4.X Login with faceboook Default Login_button

public class FbDefaultBtnLogin extends AppCompatActivity {

private CallbackManager callbackManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(getApplicationContext());
    setContentView(R.layout.activity_fb_default_btn_login);
    callbackManager = CallbackManager.Factory.create();
  //  LoginButton loginButton=(LoginButton)findViewById(R.id.login_button);


LoginManager.getInstance().logInWithReadPermissions(this,Arrays.asList("email","user_photos","public_profile"));
         LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

            }

            @Override
            public void onCancel() {

            }

            @Override
            public void onError(FacebookException e) {

            }
        });
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        callbackManager.onActivityResult(requestCode, resultCode, data);
    }


<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.jitendra.facebooklogin.FbDefaultBtnLogin">

<!--<com.facebook.login.widget.LoginButton-->
    <!--android:id="@+id/login_button"-->
    <!--android:layout_width="wrap_content"-->
    <!--android:layout_height="wrap_content"-->
    <!--android:layout_gravity="center_horizontal"-->
    <!--android:layout_marginTop="30dp"-->
    <!--android:layout_marginBottom="30dp" />

</RelativeLayout>

In Mainifest:-

 <meta-data
        android:name="com.facebook.sdk.ApplicationId"
        android:value="@string/app_id" />
 <activity
        android:name="com.facebook.FacebookActivity"
        android:theme="@style/AppTheme" >
 </activity>

Is there any tutorial or example showing how to login using own Button using Facebook SDK 4.0 in Android? I am not getting anywhere and using facebook developers site it is difficult to understand.Like below when calling FBlogin button I want to check go for login if user has not logged in or if logged in I want the access token to get facebook profile information and user likes.

FBlogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
             //Facebook login Code to get profile info and user likes  
        }
    });

I have tried also loginButton Facebook.

  <com.facebook.login.widget.LoginButton
            android:id="@+id/login_button"
            android:layout_width="244dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:layout_marginTop="30dp"
            android:layout_marginBottom="30dp" 

/>

But it is showing error in xml :-
