android - 使用不直接提供 APK 的自定义 URL 处理延迟深层链接

Question

我正在使用 Branch.io 为我的 Android 应用实现延迟深层链接

我正在研究用户单击链接但未安装应用程序的用例(安装应用程序时我的链接已经可以使用)。目前我的应用程序未托管在 Play 商店上，而是托管在 Fabric 中。因此，我设置了深层链接以将用户重定向到如下网址: https://betas.to/ ...这样他最终就可以下载 Beta，然后下载应用程序。

不幸的是，我无法使以下用例发挥作用:

-> 用户从 Android 设备(无应用)点击深层链接

-> 用户访问 Fabric 网页并提供他的电子邮件进行测试

-> 用户打开 Fabric 电子邮件

-> 用户下载 Beta(可选)

-> 用户下载 Beta 版应用

-> 应用程序启动，并考虑延迟的深层链接

最后一步出现问题:不再考虑初始深层链接。我猜这是因为应用程序最终没有从链接打开。

我可以期望这个流程以某种方式工作吗？如果没有，我想知道我在 Branch 仪表板中提供的 URL 是否必须直接指向 APK 文件。

更新1

我刚刚意识到，当我测试延迟的深层链接(在 Branch deferred deeplink testing procedure 之后)时，我遇到了与分支相关的错误。仅当我在单击链接后立即从 Android Studio 安装应用程序时，才会发生此错误。我觉得有些东西正在阻止 Branch 正确捕获应用程序安装事件。

这是我得到的:

下面一行是:

BranchSDK: Failed resolution of: Lcom/android/installreferrer/api/InstallReferrerClient;

Answer 1

缺少的类 (com.android.installreferrer.InstallReferrerClient) 是 Branch 的依赖项，但不会自动包含。您必须自己将其添加到您的构建中。

implementation 'com.android.installreferrer:installreferrer:1.0'

参见 Branch's gradle file .

已添加到 version 2.17 ，但文档似乎没有跟上。

在阅读提交之后，这个堆栈跟踪可能有点转移注意力。该库捕获 ClassNotFound 异常并记住该类不可用。它也有助于打印异常。

但是，install referrer package涉及跨安装跟踪引荐来源网址，因此与您的重现步骤相符。
