Questions:

I know this is a very common question, btu I have read through all the stack overflow questions without finding an answer.

I’m trying to integrate the Facebook Login Button using Facebook SDK 4.0.1 added through Gradle, but I get the following error.

  java.lang.RuntimeException: Unable to start activity ComponentInfo{se.speedle.android/com.bryderi.speedle.android.activity.MainActivity}: android.view.InflateException: Binary XML file line #26: Error inflating class com.facebook.widget.LoginButton

I can see the LoginButton class in Android Studio, so it kind of works

Here’s my build.gradle dependencies

dependencies {

aspects 'org.robobinding:robobinding:0.8.9'
compile 'org.springframework.android:spring-android-rest-template:2.0.0.M1'
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:21.0.3'
compile 'com.android.support:support-v13:21.0.3'

compile 'com.android.support:recyclerview-v7:21.0.3'
compile 'com.fasterxml.jackson.core:jackson-databind:2.3.2'
compile 'com.jakewharton:butterknife:6.1.0'
compile 'com.facebook.android:facebook-android-sdk:4.0.1'
compile 'me.alexrs:recyclerview-renderers:1.0.3'
compile 'com.google.android.gms:play-services:6.5.87'
}

Here’s my layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:padding="20dp" >

    <com.facebook.widget.LoginButton
        android:id="@+id/connectWithFbButton"
        style="@style/com_facebook_loginview_default_style"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_gravity="center_horizontal"
        android:text="  connect_with_facebook"/>
</LinearLayout>

And the relevant parts of my activity

@Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        FacebookSdk.sdkInitialize(getApplicationContext());


        callbackManager = CallbackManager.Factory.create();


        setContentView(R.layout.activity_main);

        // Set a Toolbar to replace the ActionBar.
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        // Find our drawer view
        dlDrawer = (FragmentNavigationDrawer) findViewById(R.id.drawer_layout);
        // Setup drawer view
        dlDrawer.setupDrawerConfiguration((ListView) findViewById(R.id.lvDrawer), toolbar,
                R.layout.drawer_nav_item, R.id.flContent);
        // Add nav items
        dlDrawer.addNavItem("Home", "First Fragment", ClassifiedsFragment.class);
        dlDrawer.addNavItem("Favourites", "Favourites", ClassifiedsFragment.class);
        dlDrawer.addNavItem("My Items", "Items", ClassifiedsFragment.class);
        dlDrawer.addNavItem("Settings", "Settings", ClassifiedsFragment.class);


        //dlDrawer.addNavItem("Second", "Second Fragment", SecondFragment.class);
        //dlDrawer.addNavItem("Third", "Third Fragment", ThirdFragment.class);
        // Select default
        if (savedInstanceState == null) {
            dlDrawer.selectDrawerItem(0);
        }
    }

How to&Answers:

In facebook sdk 4.0.1, LoginButton class is not inside com.facebook.widget package. It is inside com.facebook.login.widget package. So your xml declaration should look like this:

  <com.facebook.login.widget.LoginButton
    android:id="@+id/connectWithFbButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:layout_gravity="center_horizontal"
    android:text="  connect_with_facebook" />

Answer：

Caused by: The SDK has not been initialized, make sure to call
FacebookSdk.sdkInitialize() first.

Make sure you initialized facebook SDK before setContentView.

FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_main);

Answer：

Only add this methods of your app’s Application class::

FacebookSdk.sdkInitialize(getApplicationContext());

AppEventsLogger.activateApp(this);

Befeore: setContentView in onCreate Activity.

In dependencies import:

compile 'com.facebook.android:facebook-android-sdk:[4,5)' or smaller

Enjoy 🙂

Answer：

hey friends all your code is right. follow below instructions.

put FacebookSdk.sdkInitialize(getApplicationContext());
before setContentView();

and put following line in your xml parent layout

xmlns:facebook=”http://schemas.android.com/apk/res-auto”

like,

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:facebook="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

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


</RelativeLayout>

Answer：

Make sure that your Facebook SDK is initialized before setContentView
FacebookSdk.sdkInitialize(getApplicationContext()); setContentView(R.layout.activity_main);

Answer：

The SDK has not been initialized, make sure to call FacebookSdk.sdkInitialize() first

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    FacebookSdk.sdkInitialize(this.getApplicationContext());            
    setContentView(R.layout.activity_main1);
}

Answer：

Don’t forget to added the android app id in the android manifest inside the
application xml tag

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

Answer：

On Facebook docs the package is outdated.
For new versions, 4 and up the new package for the button is com.facebook.login.widget.LoginFacebook.

dependencies:

compile 'com.facebook.android:facebook-android-sdk:4.5.0'

activity_login.xml:

<com.facebook.login.widget.LoginButton
    android:id="@+id/connectWithFbButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:layout_gravity="center_horizontal" />

Enjoy!

Answer：

FacebookSdk.sdkInitialize(); is deprecated. Don’t use it anymore.

And follow this tutorial here:
https://developers.facebook.com/docs/facebook-login/android
without using the com.facebook.login.widget.LoginButton.

Try to use a normal button using this code:

/**
 * Setup Facebook Login Button
 */
@Override
public void setupFacebookLoginButton() {
    Button btnFacebook = mActivityReference.findViewById(R.id.btnFacebook);
    Drawable leftDrawable = AppCompatResources.getDrawable(mActivityReference, R.drawable.ic_facebook_icon);
    btnFacebook.setCompoundDrawablesWithIntrinsicBounds(leftDrawable, null, null, null);

    // Start Facebook integration
    LoginManager fbLoginManager = com.facebook.login.LoginManager.getInstance();
    mFaceCallbackManager = CallbackManager.Factory.create();
    fbLoginManager.registerCallback(mFaceCallbackManager, new FacebookCallback<LoginResult>() {
        @Override
        public void onSuccess(LoginResult loginResult) {
            AccessToken accessToken = loginResult.getAccessToken();
            // Your accessToken is here
        }

        @Override
        public void onCancel() {
            Log.d("asd", "asd");
        }

        @Override
        public void onError(FacebookException e) {
            Log.d("asd", "asd");
        }
    });

    btnFacebook.setOnClickListener(v -> fbLoginManager.logInWithReadPermissions(
        mActivityReference,
        Arrays.asList("email", "public_profile", "user_birthday")));
}

/**
     * Facebook Call Back
     *
     * @param requestCode request code
     * @param resultCode  result code
     * @param data        data
     */
    @Override
    public void facebookCallBack(int requestCode, int resultCode, Intent data) {
        if (mFaceCallbackManager != null) {
            mFaceCallbackManager.onActivityResult(requestCode, resultCode, data);
        }
    }
