Facebook分析无法识别平台

我为iOS和Android应用程序配置了FB分析 . 在正确查看事件时，它确实识别iOS平台 . 但是对于Android来说，它只有30％的资格才能成为android . 这里's how those events are shown in FB analytics debugging screen: ('innewartości' stands for '其他'）

我想知道FB如何表彰？通过广告ID？阅读文档，但没有找到任何关于此的信息 .

这是一个被识别为android的FB响应:(混淆了一些细节）：

    "url": "https://graph.facebook.com/v2.6/000000000/activities",

}

这个被 not 识别为android：

我看不到任何有趣的变化，这将指向一个Android平台 .

更新

正如Ramkumar所建议的那样，我尝试用FB sdk发布事件，但确实有效 . 我发送给FB的段落中缺少'd really like to keep using segment, so keeping this as solution is not possible in my app. I wonder what' . 这是因为session_id在使用FB SDK时存在但在段请求中不存在？ See gist with dump from adb logcat when using FB SDK
