创建Activity

public class Activity implements NativeListener {
    protected void onCreate(Bundle savedInstanceState) {
        // 设置Activity全屏
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
             WindowManager.LayoutParams.FLAG_FULLSCREEN);
        int vis = getWindow().getDecorView().getSystemUiVisibility();
        getWindow().getDecorView().setSystemUiVisibility(vis|
            View.SYSTEM_UI_FLAG_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_IMMERSIVE);
        // 设置Activity方向
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
    // 实现NativeListener的接口
    public void onVmiEngineEvent(int event, int reserved0, int reserved1, int reserved2, int reserved3, String additionInfo){
       switch (event) {
         // 处理上报事件
         ...
       }
    }
}
