Developing Android application with OneAll SDK

OneAll SDK provides tools to use OneAll Social Login features on Android Platform. It allows logging in users and posting messages on social networks using existing OneAll connectors. The library is integrated in a few lines of code and uses native Android integration with Facebook and Twitter where possible.

Integrating SDK

Running Sample Application

In order to run sample application, number of specific settings have to be updated in the code. Open app/src/main/res/values/strings.xml file and update the following values:

• oneall_subdomain- OneAll application subdomain from your application dashboard.
• facebook_app_id- Facebook application ID used for authentication.
• fb_login_protocol_scheme- Facebook login protol scheme. generally should be in format "fb", i.e. "fb1234567890"
• twitter_consumer_key- Twitter application consumer key from Twitter Application Settings.
• twitter_consumer_secret- Twitter application consumer secrect from Twitter Application Settings.

Twitter consumer key and twitter consumer secret are optional and may be omitted if you don't want to use native Android Twitter authentication.

Including Libraries

SDK added to the project with a few lines of code using Gradle.

After opening the project, edit build.gradle file. Add this to Module-level /app/build.gradle before dependencies:

    repositories {
        mavenCentral()
        maven { 'https://maven.fabric.io/public' }
    }

Add the compile dependency with the latest version of the OneAll SDK in the build.gradle file:

    dependencies {
        compile 'com.oneall:oneall-sdk:1.0'
    }

Sync Gradle and build your project. Now you will be able to use com.oneall.OAManager in your code:

    OAManager
        .getInstance()
        .setup(this, "demo", TWITTER_KEY_OR_NULL, TWITTER_SECRET_OR_NULL);

Of course, replace "demo" with the subdomain of your OneAll application.

Setting Up Facebook Integration

This part is required in order for Facebook login to work correct. The instructions here are similar to Facebook Android Getting Started Guide .

Add your Facebook App ID to your project's strings file and update your Android manifest:

1. Open res/values/strings.xml
2. Add a new string with the name facebook_app_id and value as your Facebook App ID
3. Open AndroidManifest.xml
4. Add a uses-permission element to the manifest: <uses-permission android:name="android.permission.INTERNET"/>
5. Add a meta-data element to the application element:

    <application android:label="@string/app_name" ...>
      ...
        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
      ...
    </application>

Next, setup your Facebook application by creating and setting up development hash as described in "Create a Development Key Hash" and "Setting a Release Key Hash" sections of Getting Started Guide

Code Integration

Open the activity class that will use OneAll integration. Add the following into onCreate

    import com.oneall.oneallsdk.OAManager;
    import com.oneall.oneallsdk.rest.models.User;
    import com.oneall.oneallsdk.OAError;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Your initialization code
        OAManager
            .getInstance()
            .setup(this, "demo", TWITTER_KEY_OR_NULL, TWITTER_SECRET_OR_NULL);
        OAManager.getInstance().onCreate(this, savedInstanceState);
    }

This will initialize OneAll module and set it up with your subdomain settings.

Now, pass all activity creation events to the manager:

    @Override
    protected void onResume() {
        super.onResume();
        OAManager.getInstance().onResume();
    }
    @Override
    protected void onPostResume() {
        super.onPostResume();
        OAManager.getInstance().onPostResume(this);
    }
    @Override
    protected void onPause() {
        super.onPause();
        OAManager.getInstance().onPause();
    }
    @Override
    protected void onDestroy() {
        super.onDestroy();
        OAManager.getInstance().onDestroy();
    }
    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        OAManager.getInstance().onSaveInstanceState(outState);
    }
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        OAManager.getInstance().onActivityResult(requestCode, resultCode, data);
    }

Next, use the manager to login into OneAll:

    OAManager.getInstance().login(this, new OAManager.LoginHandler() {
        @Override
        public void loginSuccess(User user, Boolean newUser) {
            Log.v("tag", String.format("OA user %s", user.identity.name.formatted));
        }
        @Override
        public void loginFailure(OAError error) {
         Log.v("tag", String.format("Failed to login into OA: %s", error.getMessage()));
        }
    });

The SDK will show selector of platforms configured for specified OneAll subdomain:

You can use your own native design and login without activating the selector:

OAManager.getInstance().login(this, "facebook", loginHandler);

Posting Messages onto Wall

In order to post message OAManager provides postMessage method:

    public void postMessage(
            String text,
            String pictureUrl,
            String videoUrl,
            String linkUrl,
            String linkName,
            String linkCaption,
            String linkDescription,
            Boolean enableTracking,
            String userToken,
            String publishToken,
            final Collection<String> providers,
            final OAManagerPostHandler handler)

Example usage:

    OAManager.getInstance().postMessage(
            "Me and the elephant",
            "[](https://drscdn.500px.org/photo/57410272/m%3D2048/9e1b37755cc09022b7eb0993379cc6f6)https://drscdn.500px.org/photo/57410272/m%3D2048/9e1b37755cc09022b7eb0993379cc6f6",
            null,
            null,
            null,
            null,
            null,
            true,
            user.userToken,
            user.publishToken.key,
            new string[] { "facebook" },
            new OAManager.OAManagerPostHandler() {
                @Override
                public void postComplete(Boolean success, PostMessageResponse response) {
                    if (success) {
                        Log.v("posted message to user wall");
                    } else {
                        Log.v("failed to post message to user wall");
                    }
                }
            }
    );

Where user object is the same user object that was received via callback on user authentication earlier in the process. This object implements Serializable interface and can be serialized and cached between session to avoid repeated logins on every application run.
