从我的Android应用程序中，我想将其安装发布回Facebook，以便为他们的新移动应用安装广告进行转换跟踪，但我希望不使用他们的api进行转换。
所以不要做
com.facebook.Settings.publishInstall(context, appId);
我想将带有所需参数的HTTP请求发送到某个URL。
编辑：
我记录了发送到Facebook以发布应用安装的两个请求，它们看起来像这样：
请求：

我在我的应用程序中包含了一个精简版的facebook api，它不能做任何事情，但只是发送这两个请求。我会尝试一下并报告它是如何工作的。
最理想的情况是，我想从服务器发送请求，而不是从手机发送请求。

您可以通过简单的呼叫
来完成此操作FacebookHelper.appInstall(this.getApplicationContext(), "<com.your.package>",
"<your facebook app id>");
和下面的图书馆。
请记住，只有安装了facebook应用程序才能跟踪应用程序 - 然后你就拥有了originId。 如果您想在服务器上发送此请求，则必须将attributionId发送到您的服务器。

这个库使用guava checkArgument和checkNotNull如果你不使用guava，你可以跳过这些行。

如果不集成我们的SDK，就无法做到这一点。对于应用安装广告，SDK必须与您的应用集成。如果您转到应用信息中心＆gt;促进＆gt; Android Feed，有一条消息说明：
注意：这仅在您集成Facebook SDK for Android时才有效。每当有人看到您的广告时，您都会被收取费用。
