Bitly Android SDK

Getting Started

Before integrating the SDK you will need to configure your mobile app in Bitly. To do this go to Brand Manager -> Mobile Apps. When creating the Android app you will need to provide the sha256_cert_fingerprints for your app. You can determine the value using this command

keytool -list -v -keystore my-release-key.keystore

Once the app is created the app ID required later will be available on the app detail panel. Copy it for later in the setup.

To create the Digital Asset Links JSON file, which would be located at https://yourdomain.com/.well-known/assetlinks.json, you must got to Branded Short Domains -> yourdomain.com -> Mobile Behavior and associate the newly created Android App with your domain. After saving the changes you can validate the file exists.

Install the SDK

Add the following to your build.gradle file

implementation 'com.bitly:bitlysdk:1.0.x'

You may need to also add GitHub as a repository

repositories {
   maven {
      url "https://maven.pkg.github.com/bitly/bitly_android_sdk_release"
      credentials{
          username = project.findProperty("gpr.user") ?: System.getenv("GH_USERNAME")
          password = project.findProperty("gpr.key") ?: System.getenv("GH_TOKEN")
      }
  }
}

Configure the App Links

Create an Activity to handle the App Links

Configure the Activity in your AndroidManifest.xml to receive the App Links

<activity android:name=”MainActivity”>
    <intent-filter android:autoVerify="true">
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="http" android:host="yourdomain.com" />
        <data android:scheme="https" android:host="yourdomain.com" />
    </intent-filter>
    <intent-filter>
        <action android:name="android.intent.action.VIEW" />
        <category android:name="android.intent.category.DEFAULT" />
        <category android:name="android.intent.category.BROWSABLE" />
        <data android:scheme="yourscheme" android:host="*" />
    </intent-filter>
</activity>

You cannot combine your launch activity and your App Links activity. These must be two separate activities.

Multiple <intent-filter> can be created to support multiple domains

Configure the SDK for App Links

If your application doesn't already have a custom Application class, create it and configure it in the AndroidManifest.xml
Import the SDK in your Application instance
```
import com.bitly.Bitly;
```

Initialize the SDK on Application creation

@Override
public void onCreate() {
    super.onCreate();

    Bitly.initialize(this, "YOUR_APP_ID", Arrays.asList("yourdomain.com","yourotherdomain.com"), Arrays.asList("yourscheme"), new Bitly.Callback() {
        @Override
        public void onResponse(Response response) {
            // response provides a Response object which contains the full URL information
            // response includes a status code
            // Your custom logic goes here...
        }

        @Override
        public void onError(Error error) {
            // error provides any errors in retrieving information about the URL
            // Your custom logic goes here...
        }
    });
}

You can also provide the access token for shortening in the same initialize method

Import the SDK in your Activity for handling App Links
```
import com.bitly.Bitly;
```

Handle the first intent

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //Handle the intent creating the activity
    Bitly.handleIntent(getIntent());
}

Handle any additional intents after activity creation
```
@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    Bitly.handleIntent(intent);
}
```
If the activity is specified as having an android:launchMode that only allows for the creation of a single instance ("singleTop", etc) then handling intents in protected void onNewIntent(Intent intent) is necessary
Retry on error
```
Bitly.retryError(error)
```
If there are any issues in handling an App Link the operation can be retried using the following line of code in your response handler from step 2

Configure the SDK for Shortening

Configure an OAUTH token for your app http://bitly.com/a/oauth_apps
If your application doesn't already have a custom Application class, create it and configure it in the AndroidManifest.xml
Import the SDK in your Application instance
```
import com.bitly.Bitly;
```

Initialize the SDK on Application creation

@Override
public void onCreate() {
    super.onCreate();

    Bitly.initialize(this, "YOUR_APP_ACCESS_TOKEN");
}

You can combine this initialization with the App Link initialization

You can shorten from anywhere in your application

Bitly.shorten("http://theurlyouwishtoshorten.com", new Bitly.Callback() {
    @Override
    public void onResponse(Response response) {
        // response provides a Response object which contains the shortened Bitlink
        // response includes a status code
        // Your custom logic goes here...
    }

    @Override
    public void onError(Error error) {
        // error provides any errors in shortening the link
        // Your custom logic goes here...
    }
});
