Error on running an application: java.lang.exceptionininitializererror

i have dowloaded an android app source code, and this is the only activity:
package net.itskewpie.freerdp;
import android.app.Activity;
import android.os.Bundle;
public class FreeRDPActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println("111111111111111111111");
String b = test();
System.out.println(b);
}
static{
System.loadLibrary("freerdp");
}
public native String test();
}
when i try to run it i get this:
08-13 14:15:34.307: W/dalvikvm(335): Exception
Ljava/lang/UnsatisfiedLinkError; thrown while initializing
Lnet/itskewpie/freerdp/FreeRDPActivity;
