How to compose a deeplink with parameters programmatically ?

Hi,

will be great to introduce API that allows to compose deeplink with parameters programmatically...

1) compose deeplink (pseudo code):
```
return Uri.parse(MainActivity.DEEPLINK_SHOW_ON_MAP)
.buildUpon()
.clearQuery()
.appendQueryParameter("lat", String.valueOf(latLng.latitude))
.appendQueryParameter("lon", String.valueOf(latLng.longitude))
.build();

```

2) trigger deeplink:
```
/** Trigger deeplink resolving over the deep link handler activity. */
@MainThread
public static boolean trigger(@NonNull final Context context, @NonNull final Uri deeplink) {
final Intent intentLink = new Intent(context, DeepLinkingActivity.class)
.setData(deeplink);

context.startActivity(intentLink);

return true;
}

```

Start by tracing the existing deeplink handling around MainActivity.DEEPLINK_SHOW_ON_MAP and DeepLinkingActivity, including the trigger method shown in the issue. Determine how a public API could compose deeplinks with query parameters and trigger resolution; done means the proposed API supports the demonstrated latitude and longitude flow.
