将Unity IAP从1.23.5更新到2.2.4时发生构建错误，Manifest合并失败

Question

看起来Unity IAP从使用Google Play Billing 3.0.0改为3.0.1，现在我不能再构建APK了。

当我尝试为android构建APK时，我得到了这个错误：

* What went wrong:
Execution failed for task ':launcher:processDebugManifest'.
Manifest merger failed : Attribute meta-data#com.google.android.play.billingclient.version@value value=(3.0.1) from [:billing-3.0.1:] AndroidManifest.xml:15:13-34
is also present at [:GooglePlayBilling:] AndroidManifest.xml:15:13-34 value=(3.0.0).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:13:9-15:37 to override.

我尝试添加"tools.replace="；android:value就像建议说的那样，但它仍然不起作用，我不知道我做得对不对。我的自定义AndroidManifest(它是通过在项目设置>播放器>构建中检查"自定义主清单"创建的(看起来像这样：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" package="[packagename]" android:versionCode="1" android:versionName="1.0">

在更新Unity IAP之前，我可以在没有错误的情况下成功构建。我应该如何解决这个问题？我使用的是Unity 2019.4.8f1。我从软件包管理器安装了Unity IAP。这是资产链接：https://assetstore.unity.com/packages/add-ons/services/billing/unity-iap-68207

Answer 1

我想明白了。有2.aar文件都与Google Billing Library有关，导致了冲突。错误消息中提到了他们的名字(方括号中[：GooglePlayBillion:](

Assets\Plugins\UnityPurchasing\Bin\Android\billing-3.0.1aar

和

软件包/com.google.play.billing/Runtime/Plugins/GooglePlayBilling.aar

我删除了billing-3.0.1aar文件，并将Google Play billing Library更新为3.1.0，现在它可以工作了。
