Using Facebook SDK in Android Example

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;
	private Button updateStatusBtn;

	private TextView userName;
	private UiLifecycleHelper uiHelper;
	private static final List<String> PERMISSIONS = Arrays.asList("publish_actions");

	private Session.StatusCallback statusCallback = new Session.StatusCallback() {

	};

	public void buttonsEnabled(boolean 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 {
			requestPermissions();
		}
	}

	public void postStatusMessage() {
		if (checkPermissions()) {
			Request request = Request.newStatusUpdateRequest(
					Session.getActiveSession(), message,
					new Request.Callback() {
						@Override
						public void onCompleted(Response response) {
							if (response.getError() == null)
								Toast.makeText(FBActivity.this,
										"Status updated successfully",
										Toast.LENGTH_LONG).show();
						}
					});
			request.executeAsync();
		} else {
			requestPermissions();
		}
	}

	public boolean checkPermissions() {
		Session s = Session.getActiveSession();
		if (s != null) {
			return s.getPermissions().contains("publish_actions");
		} else
			return false;
	}

	public void requestPermissions() {
		Session s = Session.getActiveSession();
		if (s != null)
			s.requestNewPublishPermissions(new Session.NewPermissionsRequest(
					this, PERMISSIONS));
	}

	@Override
	public void onResume() {
		super.onResume();
		uiHelper.onResume();
		buttonsEnabled(Session.getActiveSession().isOpened());
	}

	@Override
	public void onPause() {
		super.onPause();
		uiHelper.onPause();
	}

	@Override
	public void onDestroy() {
		super.onDestroy();
		uiHelper.onDestroy();
	}

	@Override
	public void onActivityResult(int requestCode, int resultCode, Intent data) {
		super.onActivityResult(requestCode, resultCode, data);
		uiHelper.onActivityResult(requestCode, resultCode, data);
	}

	@Override
	public void onSaveInstanceState(Bundle savedState) {
		super.onSaveInstanceState(savedState);
		uiHelper.onSaveInstanceState(savedState);
	}

}

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.
