Facebook login button on Android throwing ExceptionInInitializerError

I am using Android Android SDK. If I add Facebook LoginButton to my xml layout. I get a runtime error: ExceptionInInitializerError

.

<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" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

<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>

My MainActivity:

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

    setContentView(R.layout.activity_main);

    FacebookSdk.sdkInitialize(getApplicationContext());
}

Here is the stack trace:

build.gradle (module: app)

apply plugin: 'com.android.application'

    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}

build.gradle (Project):

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
    }
}

I was unable to determine what is the reason for this Exception. I can create Facebook SDK objects, I just cannot add LoginButton to my interface. Any ideas? Thank.

public void onCreate(final Bundle savedInstanceSate) {
    super.onCreate(savedInstanceSate);
    **FacebookSdk.sdkInitialize(this.getApplicationContext());**
    setContentView(R.layout.activity_main);       
}

Initialize FacebookSdk

before setContentView

in your class.

Edgar prabhu · Answer 2 · 2016-02-17T09:28:52+0000

FacebookSdk.sdkInitialize(this.getApplicationContext());

put this line before setContentView

Neal ahluvalia · Answer 3 · 2015-04-28T05:01:45+0000

Check the sizes of the libraries where you created and the path you copied. Sometimes, when a library is partially copied, this error occurs.

There was the same problem. I fixed this by adding metadata to the manifest and FacebookActivity as described in the following link:

https://developers.facebook.com/docs/android/getting-started#login_share

Make sure you follow all the preliminary steps outlined in this Facebook documentation:

https://developers.facebook.com/docs/facebook-login/android

Then add FacebookSdk.sdkInitialize (this) before setting SetContentView

Remove mavenCentral () from node repos in build.gradle (Project) and add it to build.gradle (Module: app) like

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

repositories {
    mavenCentral()
}

defaultConfig {
    applicationId "com.ehapi.rentapp"
    minSdkVersion 14
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
}
