<wx-open-launch-app
        id="launch-app-btn"
        appid=""
        class="launch-btn"
        extinfo="{'scheme':''}"
      >
        <script type="text/wxtag-template">
            <style>.btn { height: 96px;}</style>
            <div class="btn">打开app1</div>
        </script>
      </wx-open-launch-app>
无法唤起app，但如果app已经在后台运行则可以唤起，监听launch事件是有打印数据的，没有报错
