Android 默认Unity gradle中有多个Dex文件

在达到64k方法限制后，我尝试将Unity项目导出为gradle构建。在将其导入Android Studio后，我发现了错误

错误：库使用与此项目相同的包：com.myproject.name

找到这个后，我又加了一句

我的gradle项目。现在我可以在androidstudio中运行这个项目，但是正如在对这个问题的回答中所指出的，当我尝试构建一个APK时，我现在得到了以下错误

多个dex文件定义Lcom/myproject/myappname/BuildConfig

我的gradle文件如下

// GENERATED BY UNITY. REMOVE THIS COMMENT TO PREVENT OVERWRITING WHEN EXPORTING AGAIN
buildscript {
    repositories {
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.3'

在删除不同的插件并尝试构建之后，如果我注释掉最后一个插件unity android资源，我似乎可以构建项目，但当然我的应用程序运行不正常。为什么会出现此错误，以及如何解决此问题？

您的上一个项目unity android resources在AndroidManifest.xml中的packageName与gradle parameter applicationId中的基本应用程序相同。您可以编写任何其他packageName，例如com.example.myapplication.resources。

如何将其导入Android Studio？我使用的是Unity 5.5.0f3，Build System设置为Gradle new，并勾选了导出项目复选框。构建完成后，打开AndroidStudio 2.3.3，导入项目，然后选择构建而不是根文件夹，项目在其中。导入时，Android Studio抛出一个gradle版本错误，所以我将其更新为2.3.3.Ok。你不使用Gradle New导出怎么样。只需导出为ADT遗留。遵循步骤。它将向您展示如何做到这一点，然后将添加gradle。然后按照该步骤导入它。如果失败，则导出为内部默认值，然后按照I链接中的步骤进行操作。别忘了在Android Studio中会出现错误。步骤2A将修复该错误。尝试了一下，但在尝试合并我的清单时出现了一个相当严重的错误：错误：任务的执行失败：bLA:processDebugManifest'>清单合并失败：属性meta-dataandroid.support。VERSION@value[adttest:supportcompat2600alpha1:unspecified]AndroidManifest.xml:28:9-38中的value=26.0.0-alpha1也出现在[com.android.support:support-v4:25.3.1]AndroidManifest.xml:27:9-31 value=25.3.1中。建议：在AndroidManifest.xml:26:5-28:41处的元素中添加'tools:replace=android:value'以覆盖。还有一个相当长的导入摘要，概述了gradle项目中未包含的内容，其中包含来自我的插件的大量清单文件等。感谢您的回复。如果您使用Plugins>Android目录中的'res'文件夹，那么这个包是Unity创建的默认包，您需要它来添加应用程序名本地化。要解决这个问题，您似乎必须创建一个包含本地化名称的插件并导入它，如下所述：
