import useBaseUrl from '@docusaurus/useBaseUrl';
import Link from '@docusaurus/Link';

## Android

First, add the <Link to={useBaseUrl("/docs/features/plugins/navigation")}>Navigation plugin</Link> to your Flipper client instance:

```java
import com.facebook.flipper.android.AndroidFlipperClient;
import com.facebook.flipper.plugins.navigation.NavigationFlipperPlugin;

final FlipperClient client = AndroidFlipperClient.getInstance(this);
client.addPlugin(NavigationFlipperPlugin.getInstance());
```

Navigation events in the app can then be recorded by calling `sendNavigationEvent` method of the `NavigationFlipperPlugin` instance from anywhere in the app.
This enables the Navigation Plugin to be integrated into existing navigation frameworks.

### Using Android deep links

The Navigation Plugin can be used with built-in [Deep Links for Android](https://developer.android.com/training/app-links/deep-linking).

To deep link to an activity, edit the AndroidManifest.xml and add the intent filter for the given activity, as follows:

```xml
<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="flipper" android:host="deep_link_activity" />
</intent-filter>
```

This enables the user to jump to `flipper://deep_link_activity` within Flipper.

To log that navigation event in flipper, you can send the navigation event in the Activity's `onCreate` method, as follows:

```java
public class DeepLinkActivity extends AppCompatActivity {
  @Override
  protected void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    NavigationFlipperPlugin.getInstance().sendNavigationEvent("flipper://deep_link_activity/");
    ...
```

### Third party solutions

The Navigation Plugin can easily be integrated into a third-party navigation framework.

#### AirBnB deep link dispatch

[DeepLinkDispatch](https://github.com/airbnb/DeepLinkDispatch) will work out of the box with Flipper for navigating to links, including support for url parameters.

To add logging, simply add a BroadcastReceiver to your app that is called on any incoming deep links:

```java
public class DeepLinkReceiver extends BroadcastReceiver {
  private static final String TAG = "DeepLinkReceiver";

  @Override public void onReceive(Context context, Intent intent) {
    String deepLinkUri = intent.getStringExtra(DeepLinkHandler.EXTRA_URI);
    if (intent.getBooleanExtra(DeepLinkHandler.EXTRA_SUCCESSFUL, false)) {
      NavigationFlipperPlugin.getInstance().sendNavigationEvent(deepLinkUri);
    }
  }
}

public class DeepLinkApplication extends Application {
  @Override public void onCreate() {
    super.onCreate();
    IntentFilter intentFilter = new IntentFilter(DeepLinkHandler.ACTION);
    LocalBroadcastManager.getInstance(this).registerReceiver(new DeepLinkReceiver(), intentFilter);
  }
}
```
