Setting up Facebook
Following the SPiD 2.7 release, login and signup through Facebook is now supported. The SPiD SDK uses the Facebook SDK to enable login. The currently supported version of the Facebook SDK is 3.2. This also requires a FacebookApp to be setup for your application.
For information about downloading the SDK, adding it to the project and creating a Facebook app see Facebook getting started with Android.
The next step is to add the login action and handler which is described in detail at Facebook authentication.
To use the facebook sdk the LoginActivity and ApplicationId should be added to AndroidManifest.xml, the application need permission to access internet and phone state.
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<application ...>
<activity android:name="com.facebook.LoginActivity"/>
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="your-facebook-app-id"/>
</application>
Then we define the callback for when the WebView or Facebook app finishes. This should be added in your main activity.
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
Next we need to add the actual login call, this example uses a simple LoginButton from the facebook sdk. On successfully facebook login the token is passed to the SPiD SDK for SPiD login.
LoginButton authButton = (LoginButton) findViewById(R.id.authButton); // Get button from layout
authButton.setReadPermissions(Arrays.asList("email")); // email is needed by SPiD
authButton.setSessionStatusCallback(new Session.StatusCallback() {
@Override
public void call(Session session, SessionState state, Exception exception) {
if (exception != null) {
// Handle exception from Facebook
}
if (session.isOpened()) {
SPiDConfiguration config = SPiDClient.getInstance().getConfig();
SPiDFacebookTokenRequest tokenRequest;
try {
tokenRequest = new SPiDFacebookTokenRequest(session.getApplicationId(), session.getAccessToken(), session.getExpirationDate(), new SPiDAuthorizationListener() {
@Override
public void onComplete() {
// Successful login
}
@Override
public void onSPiDException(SPiDException exception) {
// Handle SPiDException (server errors)
}
@Override
public void onIOException(IOException exception) {
// Handle IOException (connection problems)
}
@Override
public void onException(Exception exception) {
// Handle general Exception (fatal errors, should never happen if SPiDClient is correctly configured)
}
});
tokenRequest.execute();
} catch (SPiDException e) {
// Handle SPiD error(most likely configuration issues)
}
}
}
});
Also be sure to logout from both facebook and SPiD.
SPiDClient.getInstance().apiLogout(new SPiDAuthorizationListener() {
@Override
public void onComplete() {
Session.getActiveSession().closeAndClearTokenInformation(); // Remove facebook token
// Logout complete
}
@Override
public void onSPiDException(SPiDException exception) {
// Handle SPiDException (server errors)
}
@Override
public void onIOException(IOException exception) {
// Handle IOException (connection problems)
}
@Override
public void onException(Exception exception) {
// Handle general Exception (fatal errors, should never happen if SPiDClient is correctly configured)
}
});
