使用不直接提供 APK 的自定义 URL 处理延迟深度 link

Handle deferred deep link with a custom URL that does not directly provides an APK

我正在使用 Branch.io

为我的 Android 应用实施延迟深度 link

我正在处理用户单击 link 但未安装该应用程序的用例(我的 link 在安装该应用程序时已经可用)。 目前,我的应用程序未托管在 Play 商店中,而是托管在 Fabric 中。因此,我已经设置了我的深度 link 以将用户重定向到 url,例如:https://betas.to/... 这样他最终可以下载 Beta,然后下载应用程序。

不幸的是,我无法使以下用例正常工作:

-> 用户从 Android 设备(没有应用程序)点击深度 link

-> 用户访问 Fabric 网页以提供他的电子邮件进行测试

-> 用户打开 Fabric 电子邮件

-> 用户下载测试版(可选)

-> 用户下载 Beta 版应用

-> 应用程序启动,并考虑延迟深度 link

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

我能否期望此流程以某种方式起作用?如果不是,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

我刚刚意识到在测试我的延迟深度 link(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 link 后从 Android Studio 安装应用程序时才会发生此错误。 我觉得有什么东西阻止 Branch 正确捕获应用程序安装事件。

这是我得到的:

下一行是:

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

这里是 Branch 的 Brian。

如果安装应用程序时常规深度 linking 有效,则延迟深度 linking 也应该有效。请确保您在 onStart 方法中初始化 Branch 并覆盖 onNewIntent:

此外,我会通过单击分支 link 并通过 Android Studio 在设备上构建应用程序来测试延迟深度 linking:

自定义URL不需要直接指向APK文件。如果您仍然 运行 遇到问题,请写信给 integrations@branch.io.

TLDR; 你应该总是在 activity :

Branch.getInstance().initSession(BranchReferralInitListener callback, @NonNull Uri data, Activity activity)

即使你有一个空 URI


自从 Branch API 用 @NonNull 注释了这个参数,我就糊涂了。

我检查了源代码并确认 Branch 正确处理了空值。当null为passed-in时,Branch会自动检测是冷启动,还是deferred deeplink.

这是相关的 piece of code from their github :

// In case of a cold start by clicking app icon or bringing app to foreground Branch link click is always false.
if (intent.getData() == null || (!isActivityCreatedAndLaunched && isIntentParamsAlreadyConsumed(activity))) {
    // Considering the case of a deferred install. In this case the app behaves like a cold start but still Branch can do probabilistic match.
    // So skipping instant deep link feature until first Branch open happens
    if (!prefHelper_.getInstallParams().equals(PrefHelper.NO_STRING_VALUE)) {
        JSONObject nonLinkClickJson = new JSONObject();
        try {
            nonLinkClickJson.put(Defines.Jsonkey.Clicked_Branch_Link.getKey(), false);
            nonLinkClickJson.put(Defines.Jsonkey.IsFirstSession.getKey(), false);
            prefHelper_.setSessionParams(nonLinkClickJson.toString());
                isInstantDeepLinkPossible = true;
        } catch (JSONException e) {
             e.printStackTrace();
        }
    }
}

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

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

Branch's gradle file 中查看。

它是在 version 2.17 中添加的,但文档似乎没有跟上。

阅读提交后,此堆栈跟踪可能有点误导。该库捕获 ClassNotFound 异常并记住 class 不可用。它还有助于打印异常。

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。
