多个dex文件定义了Landroid/support/v4/accessibilityservice/AccessibilityServiceInfoCompat。

If I run gradle assembleDebug from the command line, I am suddenly getting this error:

如果我从命令行运行gradle assembleDebug，我将突然得到这个错误:

If I grep for v4 I see two files inside my build folder.

如果我对v4进行grep，我将在构建文件夹中看到两个文件。

Binary file build/pre-dexed/debug/support-v4-19.0.0-2ba5fdd60a6c3836b3104a863fe42897da1fa9d1.jar matches
Binary file build/pre-dexed/debug/support-v4-r7-227d905d79b23b20866531d4f700446c040a2ccb.jar matches

My gradle file includes only this support library:

我的gradle文件只包括这个支持库:

compile 'com.android.support:support-v13:19.0.0'

I am stumped as to how the r7 library is included somehow. I've run gradle clean and it always appears there when I rerun assembleDebug.

我被难住了r7图书馆是怎么被包括进来的。我已经运行了gradle clean，当我重新运行组装调试时，它总是出现在那里。

If I grep for r7 inside the build directory, I see it inside the file:

如果我在构建目录中为r7 grep，我在文件中看到它:

Binary file build/exploded-bundles/ComGoogleAndroidGmsPlayServices4030.aar/classes.jar matches

If I don't include v13, then other things don't compile.

如果我不包括v13，那么其他的东西就不会编译。

But doesn't v13 include v4 support library?

但是v13不包括v4支持库吗?

Is this an incompatibility between play services AAR bundle and the v13 library?

这是游戏服务AAR bundle和v13库之间的不兼容性吗?

I grabbed the gradle file from gradleplease.appspot.com.

我从gradleplease.appspot.com获得了gradle文件。

Removing play services does not fix it; same error.

删除游戏服务并不能解决问题;同样的错误。

24 个解决方案

Run gradle -q dependencies (or gradle -q :projectName:dependencies) to generate a dependency report. You should see where r7 is coming from, such as:

运行gradle -q依赖项(或gradle -q:projectName:dependencies)生成依赖报告。您应该看到r7的来源，例如:

compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
|    +--- com.actionbarsherlock:actionbarsherlock:4.4.0
|    |    \--- com.google.android:support-v4:r7
|    +--- com.commonsware.cwac:camera:0.5.4
|    \--- com.android.support:support-v4:18.0.+ -> 18.0.0
\--- com.android.support:support-v4:18.0.+ -> 18.0.0

Then, use the exclude directive to block that dependency. In my case, it is coming from my CWAC-Camera library, and so I use:

然后，使用排除指令来阻塞该依赖项。在我的例子中，它来自于我的CWAC-Camera库，所以我使用:

dependencies {
    compile('com.commonsware.cwac:camera-v9:0.5.4') {
      exclude module: 'support-v4'
    }

    compile 'com.android.support:support-v4:18.0.+'
}

(where the second compile statement indicates what version you actually want)

(第二个编译语句表示您实际需要的版本)

That should clear matters up, as you will see if you run the dependency report again:

这应该会很清楚，因为您将看到如果您再次运行依赖项报告:

compile - Classpath for compiling the main sources.
+--- com.commonsware.cwac:camera-v9:0.5.4
|    +--- com.actionbarsherlock:actionbarsherlock:4.4.0
|    \--- com.commonsware.cwac:camera:0.5.4
\--- com.android.support:support-v4:18.0.+ -> 18.0.0

I solved similar error by adding following piece of code to my build.gradle file inside the android block.

我通过在构建中添加以下代码来解决类似的错误。android模块内的gradle文件。

android {
    dexOptions {
        preDexLibraries = false
    }
}

#3

Also to note you can see your android dependencies, by going to your Android Studio Gradle view, and selecting the target "androidDependencies".

还要注意，你可以通过android Studio Gradle视图来查看android依赖项，并选择目标“androidDependencies”。

One more tip: I was having this issue, until I removed the v4 support lib from the libs folder in both the project and my related module/library project(s).

还有一个提示:在我从libs文件夹中删除了v4支持lib之后，我就有了这个问题，我的相关模块/库项目(s)。

In case anyone finds out that the answer from CommonsWare could not be applied to android library project, here is the snippet to fix

如果有人发现来自CommonsWare的答案不能应用到android library项目，那么下面的代码片段就可以解决了。

compile (project(':yourAndroidLibrary')){ exclude module: 'support-v13' }

编译(项目(':yourAndroidLibrary')){排除模块:'support-v13'}

You will find problems

你会发现问题

Unsupported Gradle DSL method found: 'exclude()'

不支持的Gradle DSL方法发现:“排除()”

if you use compile project(':yourAndroidLibrary'){ exclude module: 'support-v13' }

如果您使用compile项目(':yourAndroidLibrary'){排除模块:'support-v13'}

The differences are the bracelet "(" and ")" before "project".

不同之处是在“项目”之前的手链“(”和“)”。

I had the same problem and it seems that my app had too many methods because of the libraries: http://developer.android.com/tools/building/multidex.html

exclude module: 'support-v4'

Would not work for me with a project dependency, the only way I could get it to work was via the following syntax:

对于一个项目依赖项，我不会为我工作，我唯一能让它工作的方法是通过以下语法:

configurations {
    dependencies {
        compile(project(':Android-SDK')) {
            compile.exclude module: 'support-v4'
        }
    }
}

Where :Android-SDK is your project name.

其中:Android-SDK是您的项目名称。

I started getting this error when upgrading to ButterKnife 8.5.1. None of the other answers here worked for me.

升级到ButterKnife 8.5.1时，我开始犯这个错误。这里的其他答案都不适合我。

I used gradle -q :app:dependencies to see the tree, and then looked through jar files until I found the conflict. The conflict was that butterknife's dependency on com.android.support:support-compat:25.1.0 contains a version of the accessibility class, and com.android.support:support-v4:23.1.1 also contains the class.

我使用了gradle -q:app:依赖关系来查看树，然后查看jar文件，直到找到冲突为止。支持:support-compat:25.1.0包含一个可访问类的版本，以及com.android.support:support-v4:23.1.1还包含类。

I solved it by changing my dependency from this:

我通过改变依赖关系来解决这个问题:

compile 'com.jakewharton:butterknife:8.5.1'

to this:

:

compile('com.jakewharton:butterknife:8.5.1') {
    exclude module: 'support-compat'
}

It doesn't seem to affect ButterKnife's operation so far.

到目前为止，这似乎并没有影响到ButterKnife的操作。

Edit: There is a better solution, which was to upgrade my android support libraries to match ButterKnife's:

编辑:有一个更好的解决方案，就是升级我的android支持库来匹配ButterKnife的:

compile('com.android.support:appcompat-v7:25.2.0')
compile('com.android.support:design:25.2.0')
compile 'com.jakewharton:butterknife:8.5.1'

I had this same error but it was because I had recently changed from using v4 to v13. So all I had to do was clean the project.

我有同样的错误，但这是因为我最近从使用v4变成了v13。所以我要做的就是清理这个项目。

#10

I had the same error on a legacy project. My fault was that the support-library was included twice: Once inside google-play-services lib, and another as standalone.

我在遗留项目上有相同的错误。我的错误是支持库包含了两次:一次是在google-play-service lib中，另一次是独立的。

This is how I fixed it:

我就是这样修正的:

BAD build.gradle:

坏build.gradle:

dependencies {
   compile files('libs/android-support-v4.jar') 
   compile files('libs/core-2.2.jar')
   compile files('libs/universal-image-loader-1.8.5-with-sources.jar')
   compile 'com.google.android.gms:play-services:3.2.65'
}

GOOD build.gradle:

好build.gradle:

dependencies {
   // compile files('libs/android-support-v4.jar')  // not needed 
   compile files('libs/core-2.2.jar')
   compile files('libs/universal-image-loader-1.8.5-with-sources.jar')
   compile 'com.google.android.gms:play-services:3.2.65'
}

In my case the problem was caused by version inconsistency:

A similar dex issue resolved method

一个类似的dex问题解决方法。

gradle.build was containing:

gradle。构建包含:

compile files('libs/httpclient-4.2.1.jar')
compile 'org.apache.httpcomponents:httpclient:4.5'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'

The issue was resolved when i removed

我移走后，问题就解决了。

compile files('libs/httpclient-4.2.1.jar') 

My gradle now looks like:

我现在的等级是:

apply plugin: 'com.android.application'

android {

compileSdkVersion 24
buildToolsVersion "24.0.3"

defaultConfig {
    applicationId "com.mmm.ll"
    minSdkVersion 16
    targetSdkVersion 24
    useLibrary  'org.apache.http.legacy'
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'

compile 'org.apache.httpcomponents:httpclient:4.5'
compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'
}

There was a redundancy in the JAR file and the compiled gradle project

JAR文件和已编译的gradle项目有冗余。

So keenly look for dependency and jar files having same classes.

如此强烈地寻找具有相同类的依赖项和jar文件。

And remove redundancy.
This worked for me.

并去除冗余。这为我工作。

I'm using com.google.android.gms:play-services-analytics:8.3.0 and android-support-v13.jar and could not get exclude module: 'support-v4' to work.

我正在使用com.google.android.gms:play-service -analytics:8.3.0和android- supportv13。jar和不能排除模块:“supportv4”工作。

My problem was i was including a library by "+" version in build.gradle. Latest version of library contained one of older dex and bang.

我的问题是，我在build.gradle中加入了一个“+”版本的库。最新版本的库包含了一个旧的dex和bang。

I reverted to older version of library and solved it.
