这是我的build.gradle文件。

从我读到现在我得到的错误是由于V4库和V7库之间的冲突。但我怎么解决它。我也尝试排除V4库但仍然没有运气。 我导入的项目也使用V4库，并且依赖于V4库。

dependencies {
     compile 'com.android.support:support-v4:20.0.0'
}

任何帮助将不胜感激。 感谢。

这不是v4-support和v7-appcompat之间的冲突，但如果你有后者则不需要前者。无论如何，它所抱怨的重复类并非来自那里。您应该能够在Android Studio中找到导航＆gt;在Escaper中的类和类型，您应该能够看到定义它的多个库。

我做了一个示例项目，其中我只包含了来自项目的包含来自jcenter的可下载依赖项的包含，我可以看到这个库提供了它的副本：

compile 'oauth.signpost:signpost-commonshttp4:1.2.1.2'

虽然它是通过signpost-core-1.2.1.2.jar文件进入的。如果我查看该库的pom文件（http://search.maven.org/remotecontent?filepath=oauth/signpost/signpost-commonshttp4/1.2.1.2/signpost-commonshttp4-1.2.1.2.pom），我可以看到它已经将signpost-core作为传递依赖：

<dependencies>
    <dependency>
        <groupId>oauth.signpost</groupId>
        <artifactId>signpost-core</artifactId>
        <version>${project.version}</version>
        <scope>compile</scope>
    </dependency>

稍后在构建文件中，将其作为显式jar文件包含在内，这是冗余的来源。通过包含signpost-commonshttp，不必包含signpost-core。

顺便说一下，

路标根本不应该重新分发这些文件 - 这看起来像是图书馆中的包装错误。

请注意，如果所有内容都使用可下载库而不是显式jar文件，则构建系统通常能够避免冗余文件出现问题。如果你通过这个包括signpost-core：

compile 'oauth.signpost:signpost-core:1.2.1.2'

而不是直接包含它的jar文件，你不会看到这个问题。

一旦你解决了这个问题，你就会遇到其他问题。 httpmime与Android提供的那些文件的版本发生冲突，这个库可能是多余的，但您可以接下来跨过该桥。
