类型 androidx.appcompat.resources.R$dimen 被定义多次

Question

We have a React Native app where after upgrading to Android Studio 3.6.1 and Gradle plugin 3.6.1 we are seeing this compilation error:

Type androidx.appcompat.resources.R$dimen is defined multiple times: /Users/andrew/Software/project/android/app/build/intermediates/project_dex_archive/productionRelease/out/androidx/appcompat/resources/R$dimen.dex, /Users/andrew/Software/project/android/app/build/intermediates/project_dex_archive/productionRelease/out/15bdf8225afad69777cd7f9bd328ab094900c8289014e0107b56c5c62099dfea_3.jar:classes.dex

Answer 1

遇到同样的问题，只需清理项目并再次重建。

Answer 2

I had same issue after updating gradle version to 3.6.3 from 3.5.2 in Android Studio.

I have multiple Build Variants.

I fixed the issue by first deleting .gradle folder from the project and did Clean Project and Rebuild Project.

If you have multiple build variant you may have to do same thing for each one when you change build variants from one to another.

Answer 3

Igor Montella 对我的问题的评论解决了这个问题——降级到 gradle 插件 3.5.0。

Answer 4

我删除了android/app/build文件夹，因为我的重复项就在那里。

Answer 5

My errors were similar, with a "is defined multiple times" message.

I solved it by downgrading the Gradle plugin to 3.5.0, running the app — or at least trying to — then upgrading to Gradle plugin 3.6.2 again.

I am not sure why, but this seemed to have cleared some caches or dependencies I was not aware of.

Removing ~/.gradle or android/.gradle did not help.

Answer 6

I just run following built in routine in Android Studio:

• File > Sync Project with Gradle Files

And then it worked again :-)

Answer 7

While I was coding on the android studio on native android.Got the same problem

Type androidx.appcompat.resources.R$dimen is defined multiple times:

The problem is because of the Duplication of the BuildConfig which is present inside the JAVA (Generated) Directory

Here is the solution to fix the problem.

You have to delete the duplicate BuildConfig from the android studio by this process

1. Click on java(generated) on the Left side

2. The problem is extra Build Config Created

3. When you click any of the BuildConfig, it will show the same error display in the picture

4. Delete the extra BuildConfig and keep the original BuildConfig.

Problem Solved

Answer 8

文件->无效缓存/重启

Answer 9

I deleted ~/.gradle/caches

seems to work good. I did this because I saw ~/.gradle/caches in my error.

Type androidx.legacy.app.ActionBarDrawerToggle$Delegate is defined multiple times:
/Users/me/.gradle/caches/transforms-3/08344aeb2253f0dce062ee9436d14235/transformed/legacy-support-core-ui-1.0.0-runtime/classes.dex,
/Users/me/.gradle/caches/transforms-3/bde9e50d97f78024fdfcb4b5869842c8/transformed/legacy-support-core-ui-1.0.0-runtime/classes.dex

Answer 10

These answers are all outdated. I used 4.1.2. If you look at the path given in AS, it should point to \\app\\build\\intermediates\\project_dex_archive\\debug\\out. Go to this path, delete all the *.jar files, leaving the most recent one. I tried this and my project worked perfectly.

Don't bother with invalidates caches / restart as it won't work.

Answer 11

在我的情况下我也有同样的问题你有升级依赖它也适用于我

Answer 12

For Googlers:
In my case, I've created a benchmark module (with plugin "com.android.library" ) and made it depend on the app module (with plugin "com.android.application" ).
But library module can not depend on the application module, as Gradle does not support it.

Answer 13

@Wito Divaro, his answer helped me. If you are bothered by "R is defined multiple times.", just try to get rid of 'android/app/buid'. Furthermore, I added this below line to app/build.gradle. If you want to try, try this.

defaultConfig {
   ..............
   multiDexEnabled true
}

dependencies {
    ..............
    implementation 'androidx.multidex:multidex:2.0.1'
}

public class MyApplication extends MultiDexApplication {
    ..............
}
