属性已使用不兼容的格式定义（此处定义了原始属性） [英] Attribute already defined with incompatible format (Original attribute defined here)

问题描述

添加后无法构建项目

compile 'com.android.support:design:24.2.0'

保持以下错误：

似乎，问题在于支持矢量可绘制对象。在某些地方两次添加了某些属性。

Seems like, the problem is with supporting vector drawables. Somewhere some attributes are added twice.

例如，内置的values.xml文件包含：

For instance, built values.xml file contains:

<declare-styleable name="AppBarLayout_LayoutParams"><attr name="layout_scrollFlags"><flag name="scroll" value="0x1"/><flag name="exitUntilCollapsed" value="0x2"/><flag name="enterAlways" value="0x4"/><flag name="enterAlwaysCollapsed" value="0x8"/></attr><attr format="reference" name="layout_scrollInterpolator"/></declare-styleable>

和

<declare-styleable name="AppBarLayout_Layout"><attr name="layout_scrollFlags">
        <flag name="scroll" value="0x1"/>
        <flag name="exitUntilCollapsed" value="0x2"/>
        <flag name="enterAlways" value="0x4"/> 
        <flag name="enterAlwaysCollapsed" value="0x8"/>
        <flag name="snap" value="0x10"/>

我已将此文件添加到gradle文件中：

I have this added to gradle file:

compile 'com.android.support:cardview-v7:24.2.0' + '@aar'
compile 'com.android.support:recyclerview-v7:24.2.0' + '@aar'
compile 'com.android.support:appcompat-v7:24.2.0'
compile 'com.android.support:design:24.2.0'

推荐答案

当应用程序中存在相同库的不同版本时，就会出现问题。在这种情况下，支持库的版本会有所不同。

The problem appears when different versions of the same library present within the application. In this case, different versions of support library.

如果您在gradle文件中看不到它们，则可能会将它们添加为依赖项。在终端中运行以下命令，查看每个库的依赖项：

If you don't see them in your gradle file, then they are probably added as dependencies. Run the following in terminal, to see the dependencies for each library:

./gradlew app:dependencies

然后，找到使用旧版本的appcompat的库，并根据需要进行更新/删除。

Then, find the libraries that use old versions of appcompat and update / remove, whatever suits you.
