UnitySendMessage on Android

How do you implement this on Android?

I have import com.unity3d.player.UnityPlayerActivity (no problem)

but for some reason I cannot seem to use UnityPlayerActivity.UnitySendMessage …

cannot find symbol
[javac] symbol : method UnitySendMessage(java.lang.String,java.lang.String ,java.lang.String)
[javac] location: class com.unity3d.player.UnityPlayerActivity
[javac] UnityPlayerActivity.UnitySendMessage(“Main Camera”,“FingerTouch”,“ypi”);

The UnitySendMessage is not located in the UnityPlayerActivity but in the UnityPlayer.
So:
UnityPlayerActivity.UnitySendMessage
Should be:
UnityPlayer.UnitySendMessage
