我最近接手了一个Android Studio项目的工作，该项目的积极开发在18个月前即2018年7月停止

我已经能够构建该产品的调试版本，但还没有发布。构建失败，无法尝试构建我今天添加的新productFlavor。这是生成错误：

Multiple dex files define Landroid/support/v13/view/inputmethod/InputConnectionCompat$OnCommitContentListener;
在与模块应用程序的版本中的版本同步后，将创建新的版本变体。当我选择newFlavorDebug时，我得到了上面的错误。我可以回到localhost风格，仍然可以构建localhostDebug，并将其发送到emulator运行。然而，在经历了许多问题和答案之后，其中一个建议使用Build->Clean项目，现在我无法获得任何构建的味道

我已经从其他答案中尝试了一些东西：

  • 我已将以下内容添加到我的应用程序build.gradle中的android{}块中：
  • 我在android defaultConfig中添加了
这两个都没有帮助

我发现在这个问题上有很多不同的答案，但它们对我的情况没有帮助

以下是我的应用程序build.gradle中的配置和依赖项块：

得到一个警告，有些东西要求版本27.1.1、26.1.0和25.3.1

我从Android Studio终端使用此命令查看依赖项列表：

./gradlew -q :app:dependencies
这似乎是26.1.0的依赖性来源，但它是一个在过去5年中没有更新的代码库：

无法解决我遇到的问题的文章：

    • 添加了preDexLibraries选项，但没有帮助
    • clean build没有任何帮助（事实上，这样做阻止了以前从以前的开发人员那里得到的在clean之前构建的构建风格）
尝试以下操作：

将此代码块添加到build.gradle文件中

dexOptions {
preDexLibraries = false
}
然后清理和重建项目。

项目有两个build.gradle文件：一个在项目级别，另一个在应用程序目录下。当我尝试添加此项时，项目级别的一个会出错。app下的那个已经在android{}块中有了这个。Build->Clean Project，后跟Build->Rebuild Project仍然会失败，并出现上面显示的相同错误。gradle文件中可能有相同的库，但版本不同。好的，您对如何查看该项目以解决此问题有何建议？我已经找到了如何让gradle向我显示依赖关系（如上所述），这帮助我消除了关于不同版本的一些警告，但同样的方法似乎并没有消除其他警告。
