具有动态功能的即时应用程序始终显示带有1个选项的消歧对话框 [英] Instant app with Dynamic Features always show Disambiguation dialog with 1 option

问题描述

我正在尝试动态功能和Instant Apps。
要在各种功能之间导航，请使用深层链接。

I'm experimenting with Dynamic Features and Instant Apps. To navigate between various features, I use Deep Links.

每次导航到另一个活动时，都会看到消歧对话框少于1秒，其中包含列出了1个应用。请注意， Once和 Always（在荷兰语中）的选项是如何变灰的。

Each time I navigate to another Activity, I see the disambiguation dialog for less than 1 second, with 1 app listed. Notice how the options for "Once" and "Always" (in dutch) are greyed out.

示例Github项目

我创建了最小样本，它与我在Github上的当前结构相匹配。需要Android Studio 3.5-RC2

I created a minimalistic sample, that matches my current structure on Github. Requires Android Studio 3.5 - RC2

某些上下文：

我非常有信心，深层链接配置正确。但是既然你们还是想检查一下，这里是配置：

I'm quite confident, the deeplinks are configured correct. But since you guys want to check that anyway, here's the configuration:

1-清单：

<activity
            android:name=".ProfileActivity">

        <intent-filter
                android:autoVerify="true"
                android:priority="100">

            <action android:name="android.intent.action.VIEW" />

            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />

            <data
                    android:host="giddy.entreco.nl"
                    android:pathPrefix="/profile"
                    android:scheme="http" />
            <data android:scheme="https" />

        </intent-filter>

    </activity>

2-资产链接
我的域包含可公开访问的< a href = https://giddy.entreco.nl/.well-known/assetlinks.json rel = nofollow noreferrer> assetlinks.json

3-Sha是正确的
我使用的sha是正确的

3 - Sha's are correct The sha's I use are correct

所有支票均通过

5-测试URL意图
也可以！唯一的问题是我在短暂的时间内看到了消歧对话框。

5 - Testing a URL intent Also works! The only problem is I see the disambiguation dialog for a brief period.

其他信息

• 我在所有模块中都使用了 apply插件：'com.android.dynamic-feature'（<$ c $除外） c> app 当然）

Android Studio：3.5 RC2； Android-gradle-plugin：3.5.0-rc02

Android Studio: 3.5 RC2; Android-gradle-plugin: 3.5.0-rc02

我的设备是OnePlus6-带有氧气9.0.7& Android 9

My Device is a OnePlus6 - with Oxygen 9.0.7 & Android 9

google官方样本还显示我的设备上的这种行为

某些Samsung设备的行为不同。它没有显示使用1消除歧义选项，而是列出了我的应用两次，并且会一直等到您选择一次或始终。 （请注意，我是从Play商店的发布前报告中获得的）
< img src = https://i.stack.imgur.com/t9djg.png alt =在此处输入图片描述>

Some Samsung devices, behave different. Instead of showing the Disambiguation with 1 option, it lists my app twice, and will keep waiting until you either select Once or 'Always'. (Note, I got this from the pre-launch reports in the play store)

无论我构建APK，应用程序捆绑包还是通过Google Play下载，我都会看到这种行为。总是一样。

I see this behaviour, no matter if I build an APK, an App Bundle or download through Google Play. It's always the same.

有什么建议可以消除烦人的对话框吗？
当我分析apk /捆绑包时，我确实看到了两个特定于 Activity 的条目。不仅在基本模块的清单中，而且在配置文件模块的清单中。我对Android / PlayStore在安装模块时如何合并这些清单几乎一无所知，但我想在这种情况下查看对话框可能很有意义。

Any suggestions to get that annoying dialog out of the way? When I analyse the apk/bundle, I do see two entries for the specific Activity. Once in the base module's manifest, but also in the profile module's manifest. I have little understanding of how Android/PlayStore merges those manifests while installing modules, but I guess it could make sense to see the dialog in this case.

推荐答案

所以是的...我相信我以前已经看到过，从一种动态功能导航时，这是一种奇怪的行为。通过URL意向（即时）到另一个（非即时）。

So yes... I believe I have seen this before, it is some odd behavior when navigating from one dynamic-feature (instant) to another (non-instant) via a URL intent.

在解决此问题之前，我不建议您使用URL意向在模块之间导航，使用反射直接进入另一个模块的活动，例如：

Until this gets addressed, I don't recommend using a URL intent to navigate between modules, instead, use reflection to directly get to the other module's activity, example:

if (doesModuleExist()) {
    val intent = Intent()
        .setClassName(getPackageName(), "com.sample.ProfileActivity")
        .addCategory(Intent.CATEGORY_DEFAULT)
        .addCategory(Intent.CATEGORY_BROWSABLE)
    startActivity(intent)
}

其中 doesModuleExist（）检查是否有以下情况：

Where doesModuleExist() checks if either:

1. 正在检查示例清单，看来您的个人资料模块不属于您的示例模块即时应用程序 dist：instant = false ，因此您将永远无法访问它e您可以简单地执行 isNotInstantApp（）来检查，并且永远不会在作为即时应用程序时尝试启动。

1. examining your sample manifest, it looks like your profile module is not part of your instant app dist:instant="false", so you would never have access to it, therefore you could simply do a isNotInstantApp() check instead and never attempt the launch while as instant app.

一旦在已安装的应用程序中运行，则从技术上讲您无需检查，因为它始终是 include = true

once in your installed app, then you technically don't need to check, as it is always include="true"

，但是如果您的配置文件模块是onDemand模块，或者只是出于安全预防措施，则应使用 splitInstallManager.getInstalledModules（），请参见 / app-bundle / playcore＃manage_installed_modules （注意，您也可以在您的即时应用中使用此API）

but if your profile module is an onDemand module, or just for safety precautions, you should utilize splitInstallManager.getInstalledModules(), see /app-bundle/playcore#manage_installed_modules (note, you can also use this API in your instant app)

设备，这可能意味着它们在拦截和处理该URL意图方面实现了细微的差异，并且/或者它只是一个不同的Android版本（pre-O与O +）。

And since it looks like this odd behavior varies between different devices, that might mean they've implemented subtle differences in intercepting and handling that URL intent, and/or it's just a different Android version (pre-O vs O+).

也是，关联多个软件包名称到 common.handle_all_urls 的单个网站域时，当系统尝试在您的应用上线时尝试验证关联时，可能会导致其他一些不当行为。

Also yes, associating multiple package names to a single website domain for common.handle_all_urls might cause some additional misbehavior when the system tries to verify the association when your app goes live.
