This tutorial explains how to how to use Facebook SDK APIs in Android. This tutorial allows user to login to Facebook first and then allows to do following things
- Login to Facebook
- Share status message to Facebook wall
- Share Image to Facebook wall
This example using Facebook SDK 3.0 for Android which is available for free download from the Facebook’s developer console. This Facebook SDK comes with almost all the functionality of the native Facebook app to your own Android app. Follow the below steps
Creating an App on Facebook
Before integrating Facebook SDK to your android app you have to create a Facebook app on your Facebook developer console. Visit Facebook developer console and create a new Facebook application. Once you create the application you will get an app id, which is used to uniquely distinguish your application from others. This AppID will be used along with each of the request we make to Facebook server. Don’t get panic, sometime it takes some time to make your application go live.
Using Facebook SDK in Android
- Now you have created an Facebook app in developer console and you are ready to start with our Android app. You may create a new project or import an existing one.
- Import Facebook SDK to your eclipse workspace and make sure it builds successfully. Once it builds we have to attach the Facebook library project to your Android project. The easiest way to attach the SDK is to add it as an Android library by going to the project’s properties.
- Now do the following changes to your application manifest file. Put the following code before </application> tag. Make sure you are using your own AppID obtained from Facebook developer console.
<activity android:name="com.facebook.LoginActivity"
android:theme="@android:style/Theme.Translucent.NoTitleBar" />
<meta-data android:name="com.facebook.sdk.ApplicationId"
android:value="@string/app_id" />
Note: Make sure that you have give android.permission.INTERNET permission in your application manifest file.
Activity Layout
Now define layout for your activity class. In this example, We have three sample buttons.
<?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/fb_login_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
facebook:confirm_logout="false"
facebook:fetch_user_info="true" />
<TextView
android:id="@+id/user_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="10dp"
android:textSize="18sp" />
<Button
android:id="@+id/update_status"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/update_status" />
<Button
android:id="@+id/post_image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/post_image" />
</LinearLayout>
Activity Java Class
public class FBActivity extends FragmentActivity {
private LoginButton loginBtn;
private Button postImageBtn;

if (state.isOpened()) {

Log.d("FacebookSampleActivity", "Facebook session opened");
} else if (state.isClosed()) {

Log.d("FacebookSampleActivity", "Facebook session closed");
}
}
};
public void buttonsEnabled(boolean isEnabled) {
postImageBtn.setEnabled(isEnabled);
updateStatusBtn.setEnabled(isEnabled);
}
public void postImage() {
if (checkPermissions()) {
Bitmap img = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
Request uploadRequest = Request.newUploadPhotoRequest(
Session.getActiveSession(), img, new Request.Callback() {
@Override
public void onCompleted(Response response) {
Toast.makeText(FBActivity.this,
"Photo uploaded successfully",
Toast.LENGTH_LONG).show();
}
});
uploadRequest.executeAsync();
} else {

com.facebook.widget.loginbutton error in xml showing n also r cannot be resolved to a variable android
com.facebook.widget.LoginButton has been changed to com.facebook.login.widget.LoginButton in version 4 of Facebook SDK. Using that should fix the error with both xml and R.

Looks like some issue with the Facebook sdks. At runtime the sdks is not found. Rebuild or restart eclipse.
Thank you. This is 10 times better than the official facebook documentation.
Don’t have the example but you can refer the api document here
https://developers.facebook.com/docs/reference/android/current
unfortunately stopped in my device
Please do paste the error log. Difficult to trace without it.
thanks a lot

you may store the token.

some methods are pretty confusing ?
Please do refer to official facebook developer portal for complete documentation
https://developers.facebook.com/docs/android
can this be achieved without fragments? Would like to reach earlier devices to Level 11. Thanks!
@Risk, very much doable with simple activity.
Life Saver !
Perfect example… I was messing around on the Facebook dev pages for a few hours and didn’t get very far. This sample exactly what I was looking for.
code works finely…i wanna share url with image on facebook wall.. can you post me the code to do it
but where the user login details taken for new user
i can only run the App successfully once even I commented the sentence “buttonsEnabled(false); “. how can i do if i want to send several status by clicking the button for several times?
Same here…
