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;
import org.apache.http.client.HttpClient;

import org.json.JSONObject;

import com.facebook.android.AsyncFacebookRunner;
import com.facebook.android.DialogError;
import com.facebook.android.Facebook;
import com.facebook.android.FacebookError;
import com.facebook.android.Facebook.DialogListener;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.AsyncTask;
import android.os.Bundle;
import android.util.Log;

@Override
/**

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

/**

*/
btnFacebook.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
/**
* check for network connectivity
*/
if (isNetworkAvailable(context) == true) {
accessTokenFacebook();

} else {
Toast.makeText(MainActivity.this, "No Network Connection",
Toast.LENGTH_SHORT).show();
}

}
});
}

}

/**

public void accessTokenFacebook() {

mPrefs = getPreferences(MODE_PRIVATE);
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);
}

/**
* Only call authorize if the access_token has expired.
*/
if (!facebook.isSessionValid()) {

facebook.authorize(this, new String[] {}, new DialogListener() {
public void onComplete(Bundle values) {
try {

editor.commit();
new getFacebookData().execute();
} catch (Exception e) {
// TODO: handle exception
}
}

public void onFacebookError(FacebookError error) {
}

public void onError(DialogError e) {
}

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

}

/**
* Async class for getting facebook data in background thread
*
* @author manish
*
*/

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

ProgressDialog pd = null;

@Override
protected void onPreExecute() {
pd = ProgressDialog.show(MainActivity.this, "Please wait",
"Loading please wait..", true);
pd.setCancelable(true);

}

@Override
protected String doInBackground(String... params) {

return null;
}

if (Connectiontimeout != true) {

}

/**

while ((webServiceInfo = rd.readLine()) != null) {

imageURL = jsonObjUrl.getString("url");
profilePic = BitmapFactory.decodeStream((InputStream) new URL(
imageURL).getContent());
}

} catch (Exception e) {
Connectiontimeout = true;
}
}

}


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,

  3. Hi Manish ,Good Tutorial but how can i get key hash ??

    ReplyDelete
    Replies
    1. Firstly, to generate your key hash on your local computer, run Java's keytool utility (which should be on your console's path) against the Android debug keystore. This is, by default, in your home .android directory).
      On Linux-
      keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

      On Windows-
      keytool -exportcert -alias androiddebugkey -keystore %HOMEPATH%\.android\debug.keystore | openssl sha1 -binary | openssl base64

      For more help read facebook help page-

    1. It is old Facebook SDK, please follow Facebook developer for latest update.

      And there is no direct Native SDK for debit/credit card implementation. You need any third party library to implement.
