Is it possible to make a wear app that connects to my android app activity(maps)

Question

I have a program that has one activity which the user can record his trip by pressing a button from one place to an other.I want somehow to make a wear app that connects with this activity so the user can press that button from the smartwatch and basically do whatever the android activity does.

Here is the code in case it's helpful

Map.java

Answer 1

Using the Maps SDK for Android, you can create a map-based wearable app

The following code sample enables ambient mode in the app and in the map:

public class MainActivity extends WearableActivity
    implements OnMapReadyCallback, GoogleMap.OnMapLongClickListener {

private MapFragment mMapFragment;

public void onCreate(Bundle savedState) {
    super.onCreate(savedState);

    // Enable ambient support, so the map remains visible in a simplified,
    // low-color display when the user is no longer actively using the app
    // and the app is still visible on the watch face.
    setAmbientEnabled();

    // ... Perform other activity setup processes here too ...
}

/**
 * Starts ambient mode on the map.
 * The API swaps to a non-interactive and low-color rendering of the map
 * when the user is no longer actively using the app.
 */
@Override
public void onEnterAmbient(Bundle ambientDetails) {
    super.onEnterAmbient(ambientDetails);
    mMapFragment.onEnterAmbient(ambientDetails);
}

/**
 * Exits ambient mode on the map.
 * The API swaps to the normal rendering of the map when the user starts
 * actively using the app.
 */
@Override
public void onExitAmbient() {
    super.onExitAmbient();
    mMapFragment.onExitAmbient();
}

}
