Realtime data exchange between Android Wearable and Handheld -

i working on simple app run on both wearable(samsung gear live) , handheld(moto g). want display info wearable's heart rate sensor, accelerometer , gyroscope on handheld. best way accomplish this. using dataapi, since updating info each second, allocating much memory, , killed os. here service runs on wearable

try using message api instead of info api. create message containing info , send on other device : http://developer.android.com/reference/com/google/android/gms/wearable/messageapi.html
