未安装动态功能模块

Question

我正在我的应用上添加按需动态功能模块，但我遇到了问题。

当我安装那个功能模块时

val request = SplitInstallRequest.newBuilder()
    .addModule("ondemandfeature")
    .build()
splitInstallManager.startInstall(request)

打印以下日志

这让我相信动态功能模块已成功安装。但是当我尝试检查已安装的模块时：

splitInstallManager.installedModules

它返回一个空列表。

我有什么遗漏吗？

附加信息：

这是SplitInstallStateUpdatedListener的日志：

// begin
PENDING (printed 4x)
DOWNLOADING (printed 14x)
INSTALLING (printed 1x)
DOWNLOADED (printed 1x)
// end

我还发现，在INSTALLING 日志之后，会打印以下内容：

I/Finsky: [2] dyv.<init>(17): com.package.my is installed but certificate mismatch

什么意思？

附加信息 2：

在 Pixel 3XL (Android 10) 设备上，按需动态功能模块已成功下载并安装。

但是，在摩托罗拉 G5 (Android 8.1) 设备上，仅下载按需动态功能模块，而从未安装。

附加信息 3：

由于某种原因，下载和安装只能在 Android 10 设备上运行，但我不知道为什么。

为了测试该功能，我正在使用内部应用共享工具，我可以在其中上传应用包。

Answer 1

我发现由于我的项目配置错误，我遇到了这些问题。

请确保在您的项目中正确设置了以下内容：

• 使用SplitCompatApplication 作为Application 类；
• 在使用动态功能的Activities 上调用SplitCompat.installActivity(this)；

override fun attachBaseContext(newBase: Context?) {
    super.attachBaseContext(newBase)

    SplitCompat.installActivity(this)
}
