I am trying to execute a function in Java (from C) that has the following signature:

public void execute(int x, int y, int action);

My problem is to define the function signature in GetMethodID:

env->GetMethodID(hostClass, "execute", "(I;I;I;)V");

The problem I ma getting is:

W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V
W/dalvikvm( 1849): Bogus method descriptor: (I;I;I;)V
D/dalvikvm( 1849): GetMethodID: method not found: Lcom/device/client/HostConnection;.execute:(I;I;I;)V

I am not sure how to specify the method signature in GetMethodID (for 3 integers as parameters). I saw people use the ";" to separate parameters in other posts for the String and File class, but nothing with primitives like integer.

What would be the correct way to do this please?

Thank you.
