Hi,

I´ve integrated Unity with Eclipse to do a Android project following this tutorial

http://unity3d.com/support/documentation/Manual/Android-Integrating%20Unity%20With%20Eclipse.html

Integration is working OK, I can call Java methods from Unity but i can´t call Unity Methods from Java Classes…It would be wonderfull if somebody could help me…

Thanks a lot and sorry for my poor english.

You can do something like this in Java once you have integrated with eclipse using the SendMessage function.

public class myawesomeanroidapp extends UnityPlayerActivity
{

/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) 
{
	super.onCreate(savedInstanceState);
}

public void SendMessageToUnity()
{
	UnityPlayer.UnitySendMessage("Main Camera","foo",Integer.toString(fooint));
}

}

See this page under example 3 of the Android section. You do it very similarly to how you do it on iOS except that you have to create a JavaObject.
