Easy Login in your app with different social networks. Currently supported:
- Google Plus
To be able to use one of the social network connections you need to create an EasyLogin
instance:
EasyLogin.initialize();
EasyLogin easyLogin = EasyLogin.getInstance();
Also make sure to call through to EasyLogin
in onActivityResult()
of your Activity:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
easyLogin.onActivityResult(requestCode, resultCode, data);
}
Afterwards you can connect to the social networks one by one.
To connect to facebook you need to do the following:
- First of all you need to init a list of permissions you want to take:
List<String> fbScope = new ArrayList<>(); fbScope.addAll(Collections.singletonList("public_profile, email"));
- Add the facebook social network:
easyLogin.addSocialNetwork(new FacebookNetwork(this, fbScope));
- Add the Facebook LoginButton and the listeners:
facebook = (FacebookNetwork) mEasyLogin.getSocialNetwork(SocialNetwork.Network.FACEBOOK); // Use global listener to get notified in onSuccess() or onError() inside Activity facebook.setOnLoginCompleteListener(this); LoginButton loginButton = (LoginButton) findViewById(R.id.facebook_login_button); // Call this method if you are using the LoginButton provided by facebook // It can handle its own state if (!facebook.isConnected()) { // You can also use a local listener per every social login facebook.requestLogin(loginButton, this); }
- In the next step you will get an
onSuccess()
oronError()
callback. The easiest solution is to implement theOnLoginCompleteListener
in your activity and handle all the connections there.
You also need to make sure to add the Facebook ApplicationId in your manifest:
<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
One gotcha of using the Twitter Social connection is to create the TwitterNetwork
before calling to setContentView()
as Twitter would complain otherwise.
// Initialization needs to happen before setContentView() if using the LoginButton!
easyLogin.addSocialNetwork(new TwitterNetwork(this, twitterKey, twitterSecret));
setContentView(R.layout.activity_main);
twitter = (TwitterNetwork) easyLogin.getSocialNetwork(SocialNetwork.Network.TWITTER);
twitter.setOnLoginCompleteListener(this);
twitterButton = (TwitterLoginButton) findViewById(R.id.twitter_login_button);
twitter.requestLogin(twitterButton, this);
You also need to make sure to add the Fabric API Key your manifest:
<meta-data android:name="io.fabric.ApiKey" android:value="@string/fabric_app_id"/>
easyLogin.addSocialNetwork(new GooglePlusNetwork(this));
gPlusNetwork = (GooglePlusNetwork) easyLogin.getSocialNetwork(SocialNetwork.Network.GOOGLE_PLUS);
gPlusNetwork.setOnLoginCompleteListener(this);
gPlusButton = (SignInButton) findViewById(R.id.gplus_sign_in_button);
gPlusButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (!gPlusNetwork.isConnected()) {
gPlusNetwork.requestLogin(MainActivity.this);
}
}
});
You also need to include a valid google-services.json
file in your project to be able to use G+:
For more information you can consult the official docs.
public class MainActivity extends AppCompatActivity implements OnLoginCompleteListener {
[...]
@Override
public void onLoginSuccess(SocialNetwork.Network network) {
// You can check the network by e.g.: if (network == SocialNetwork.Network.FACEBOOK)
AccessToken token = network.getAccessToken();
Log.d("MAIN", "Login successful: " + token.getToken());
}
@Override
public void onError(SocialNetwork.Network socialNetwork, String requestID, String errorMessage, Object data) {
Toast.makeText(getApplicationContext(), errorMessage, Toast.LENGTH_SHORT).show();
}
