public class AAActivity extends Activity {     /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);     }         static {         System.loadLibrary("libjnigraphics");//这里写成绝对path也是不行的/system/lib/libjnigraphics.so     } }
