android-wear-data-api

I want to make bidirectional data transfer between Android Wear and Handheld. All seems to be good except triggering onDataChanged on Handheld. It triggers only then I plug in\out USB cable, connected to the PC. So I don't understand why it's happen. Here is my code: WearListenerService on Handheld: import android.content.Intent; import android.os.Bundle; import android.support.v4.content.LocalBroadcastManager; import com.google.android.gms.common.ConnectionResult; import com.google.android.gms.common.api.GoogleApiClient; import com.google.android.gms.wearable.DataApi; import com.google

I currently have an android wear watchface developed. I however would now like to create a settings section on the host app that would allow the user to customize the watchface. I am new to the android development so I am curious on the correct way to do this. Is there a way to update a sharedpreference on the host and then push or sync that with the sharedpreference on the wear device? Or is there a totally different way I should be looking at this? You can use the DataApi or MessageApi to sync your watchface configuration between Phone and Watch devices. Please take a look at the
