上面是代码
但是我的context。和WdGameSDK的实例都打印了都不是空代码如下
private void meiTuLogin(final Context context) {
// TODO Auto-generated method stub
Toast.makeText(context, WdGameSDK.getInstance().toString(), Toast.LENGTH_LONG).show();
Log.e("meiTuLogin", WdGameSDK.getInstance().toString());

    WdLoginListener wdLoginListener=new WdLoginListener() {

        @Override
        public void onCallBack(int arg0, UserInfo arg1) {
            // TODO Auto-generated method stub

        }
    };
    Toast.makeText(context, "WdLoginListener"+wdLoginListener.toString(), Toast.LENGTH_LONG).show();
    Log.e("WdLoginListener", wdLoginListener.toString());

    WdGameSDK.getInstance().login((Activity) context, new WdLoginListener() {
        @Override
        public void onCallBack(int paramInt, UserInfo paramInfo) {
            if (paramInt == WdResultCode.LOGIN_SUCCESS) {
                String uid=paramInfo.getUid();
                String access_token=paramInfo.getSessionid();
                bindUser(context,uid,access_token);
            } else if (paramInt == WdResultCode.LOGIN_CANCEL) {
                loginFailCallback("登录取消");
            } else {
                loginFailCallback("登录失败");
            }
        }
    });
}

@Override
public void login(Context context) {
    Toast.makeText(context, "login"+context, Toast.LENGTH_LONG).show();
    Log.e("login", context.toString());
    meiTuLogin(context);
}
