Answer 1

Your app doesn't need to be "on" to receive a message, just to be installed. If you want to see if the message is received, add a WearableListener on your handheld and add a specific behaviour by overriding the onMessageReceived() method.

More infos here : https://developer.android.com/training/wearables/data-layer/messages.html and here : https://developer.android.com/reference/com/google/android/gms/wearable/MessageApi.html

I think you can use the onPeerConnected() method from WearableListenerService to check if both devices are connected, before you send the message to your handheld. So you wont send message to your handheld, if it is off.

You can read the documentation of WearableListenerService.
