Sign up with Facebook in Android | Getting Facebook user detail in Android | Facebook Integration In Android

Hello friends,
        Today I am going to share very important code for Signup/Login with facebook in our application(Getting Facebook access token, user-id, user-name, email-id, gender, birthday etc). For that I am using Facebook graph API. Step by step process is given below hope it will help some one-

1)Print Screen:
a)Main page:

b)After Facebook button clicked:

2)Second step go to Facebook developer web-sight and create an app from below url-
http://developers.facebook.com/

a)For new application click on Apps button first-

b)After that click on "+Create New App"-

c)Then fill App Name: button below and press continue button-

d)Finally copy App ID/API Key

3)Create a new android application
4)Create a new Activity class "MainActivity.java"and copy below code-

package com.example.signupwithfacebook;

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.URL;

import org.apache.http.HttpResponse;

if (isNetworkAvailable(context) == true) {
accessTokenFacebook();

} else {

Toast.LENGTH_SHORT).show();
}

}
});
}

access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
// Log.e("Facebook token", access_token);

if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}

/**

*/
if (!facebook.isSessionValid()) {

} catch (Exception e) {

}

public void onFacebookError(FacebookError error) {
}

public void onError(DialogError e) {
}

public void onCancel() {
}
});
} else {
new getFacebookData().execute();
}

}

/**

*/

public class getFacebookData extends AsyncTask<String, Void, String> {

ProgressDialog pd = null;

@Override
protected void onPreExecute() {

profilePic = BitmapFactory.decodeStream((InputStream) new URL(
imageURL).getContent());
}

} catch (Exception e) {

}
}

}

5)Create a layout "activity_main.xml" and copy below code-

<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=".MainActivity" >

    <Button
        android:id="@+id/btn_facebook"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:background="@drawable/ic_launcher" />

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/textView"
        android:layout_marginTop="20dp"
        android:orientation="vertical" >

        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_below="@+id/textView1"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="20dp"
            android:text="user name:" />

        <TextView
            android:id="@+id/textView4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/textView3"
            android:layout_alignLeft="@+id/textView2" />

        <TextView
            android:id="@+id/textView5"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:layout_below="@+id/textView3"
            android:layout_marginLeft="10dp"
            android:layout_marginTop="20dp"
            android:text="your gender:" />

        <TextView
            android:id="@+id/textView6"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBottom="@+id/textView5"
            android:layout_alignLeft="@+id/textView4" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_alignRight="@+id/textView3"
            android:layout_marginTop="5dp"
            android:text="your name:" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/textView1"
            android:layout_alignBottom="@+id/textView1"
            android:layout_centerHorizontal="true" />

        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:layout_alignLeft="@+id/textView6"
            android:layout_below="@+id/textView6"
            android:layout_marginTop="17dp"
            android:scaleType="fitXY"
            android:src="@drawable/camera_image" />
    </RelativeLayout>

    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/btn_facebook"
        android:layout_alignBottom="@+id/btn_facebook"
        android:layout_centerHorizontal="true"
        android:text="Click facebok button"
        android:textSize="20sp" />

</RelativeLayout>

6)And now open your manifest.xml file and give below two permission-

<uses-permission android:name="android.permission.INTERNET" />
 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

7)Last and Important step run your application and enjoy :)

Thanks,
