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

So I was trying out the material design support library and when I added the dependency, compiled, and I got this error. I looked at similar problems and tried their solutions but it would not get fixed so I hope you can help me.

Here's my logcat:

C:\Users\Jan\AndroidStudioProjects\SwagCalculator3\app\build\intermediates\exploded-aar\com.android.support\appcompat-v7\22.2.0\res\values\values.xml
Error:(1) Attribute "rippleColor" has already been defined

and here is my build.gradle:

apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion "22.0.1"

defaultConfig {
    applicationId "com.raptor.swagcalculator.swagcalculator"
    minSdkVersion 21
    targetSdkVersion 22

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

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:design:22.2.0'
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:support-v4:22.2.0'
compile 'com.android.support:cardview-v7:22.2.0'
}

Solution

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
