Parse.com推送通知未发送到所有设备

[英]Parse.com Push notifications not being sent to all devices

原文 2015-03-27 15:01:27 5 1 android/ mobile/ parse-platform/ cloud

I've created an app that is currently being used to notify people about the happenings in and around our college using Parse's push notifications service. 我创建了一个应用程序，该应用程序目前正在使用Parse的推送通知服务来通知人们我们大学内外的情况。 I have close to a 1000 downloads so far. 到目前为止，我的下载量已接近1000。

However, when I send a push it gets delivered to only about 600 devices. 但是，当我发送推送时，它只能传递到大约600台设备上。

Can someone help me with what's happening? 有人可以帮我解决所发生的事情吗？

1 个解决方案

There are a couple possibilities that come to mind: 我想到了两种可能性：

Already mentioned but a good point is that users could have installed, created a user, then uninstalled and are no longer using the app. 已经提到过，但一个好处是，用户可以安装，创建用户，然后卸载并不再使用该应用程序。
Some users could have opted to not receive push notifications and therefore would not be sent push notifications. 一些用户可能选择不接收推送通知，因此不会发送推送通知。

You can check to see how many people have opted to receive push notifications by looking at how many rows you have in the _installations table. 您可以通过查看_installations表中的多少行来查看有多少人选择接收推送通知。 If the number is close to the 600 then likely the rest of the users have opted out of push notifications. 如果该数字接近600，则其他用户很可能已退出推送通知。 If the number is closer to the 1000 mark when they uninstalled your app they would no longer receive the push notifications. 如果该数字在卸载您的应用程序时接近1000，则它们将不再收到推送通知。

You may consider this option as well to see how many users have uninstalled. 您也可以考虑使用此选项，以查看有多少用户已卸载。 This stackoverflow article may help. 这篇stackoverflow文章可能会有所帮助。
