报告Android应用安装回Facebook,而不使用他们的api

Question

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.

所以不要这样做

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:

我记录了两个发送到Facebook发布应用程序安装的请求,它们看起来像这样:

请求:

GET /[app id]?format=json&sdk=android&fields=supports_attribution HTTP/1.1

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.

Answer 1

您可以通过简单的调用来完成此操作

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，您才能跟踪应用程序 - 然后您就有 attributionId。如果您想在服务器上发送此请求，您必须将 attributionId 发送到您的服务器。

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