Gradle error: “Attribute ”rippleColor“ has already been defined” in android studio

被刻印的时光 ゝ 提交于 2019-11-27 16:00:16

I have same issue , after long search I found there are some libraries use the same attribute rippleColor

Example:

1- Google play service

compile 'com.google.android.gms:play-services:7.8.0'

2- Design Support Library

compile 'com.android.support:design:22.2.0'

3- MaterialDesign

compile 'com.github.navasmdc:MaterialDesign:1.5@aar'

Fix this issue

First to fix this issue replace google play service package (whole package) with specific one you need , please review google site as in Google Wallet there attribute called rippleColor , in my case all I need google maps com.google.android.gms:play-services-maps:7.8.0

Second you can replace Design Support Library compile com.github.navasmdc:MaterialDesign:1.5@aar with compile 'it.neokree:MaterialNavigationDrawer:1.3.2' , if you need to use navigation drawer only

I hope this help

I found the solution here (https://github.com/navasmdc/MaterialDesignLibrary/issues/289 ). The MaterialDesign Library's rippleColor attritube is replaced with mRippleColor attribute and the compiled library is forked here (https://github.com/vajro/MaterialDesignLibrary).

Adding

repositories {
maven { url "https://jitpack.io" }

}

and replacing

compile 'com.github.navasmdc:MaterialDesign:1.5@aar'

with

compile 'com.github.vajro:MaterialDesignLibrary:1.6'

in your build.gradle file should solve the issue.

It seems that in the projects you are using (your own application + the used libraries) the Attribute named rippleColor is used at least two times.

I'd suggest to check through your xml-s containing colors or any attributes (e.g colors.xml, or any other, try search for it in the whole project in your IDE).

Check whether the mentioned rippleColor is used multiple times. If you have it in your project, rename it!

I also met this problem when using Material Design, this is because "rippleColor" conflicts with android support design package. If you downloaded the module and added it as a dependency, you can solved this problem as follows :

  1. Press shift-cmd-R to Replace in Path,
  2. Text to find : rippleColor
  3. Replace with : mrippleColor
  4. Check "Whole words only(may be faster)"
  5. press "find" button to replace

then click Build-Rebuild to rebuild the project, and it could build successfully.

Or you can just use this forked library: link, he did that replace job for you.

I got the same issue because I'm using the MaterialDesign Library in my android application where the rippleColor attribute is defined. Here is the example which shows how I've solved this issue.
