android - 在 Android Studio 上为 Android 构建 OutsystemsNow 获取 dexException

Question

我已将 Outsystems Now android 应用程序导入到 Android Studio 中。在尝试导入项目并解决所有模块导入的几个小时后。我目前遇到此错误，我无法找出问题所在。

这是我要构建运行的应用程序: OutsystemsNow-Android

Error:Execution failed for task ':dexDebug'.

我已经搜索了类似的错误并尝试了堆栈溢出中提供的大多数解决方案，但没有一个解决了我的问题:\

Answer 1

这类问题的“通用”答案是您的项目包含多个库，并且某些库出现了两次(因为它可能已经包含在您包含的库之一中)。

在这种特定情况下，似乎多次定义了以下类(可能是因为它所属的库被多次包含):

android/support/v7/app/ActionBar$Callback;

您可以通过运行以下 gradle 命令查看您的项目正在使用哪些库:

gradle -q dependencies 

一旦找到重复的库，您可以通过在依赖项部分指定“exclude”来删除它。类似于以下内容:

compile ('com.android.support:appcompat-v7:+'){
    exclude module: 'support-v4'
}
