How to fix mixed version in android build.gradle? (libraries must use the exact same version)

Question

I have a problem in gradle configuration, I get this error

All com.android.support libraries must use the exact same version specification (mixing versions can lead to runtime crashes). Found versions 28.0.0-alpha1, 27.1.1, 27.0.2. Examples include `com.android.support:animated-vector-drawable:28.0.0-alpha1` and `com.android.support:cardview-v7:27.1.1`

How do I fix this problem?

Here is the complete buil.gradle configuration.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.sakan"
        minSdkVersion 15
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation fileTree(dir: 'libs', include: ['*.jar'])

}

I think one of the dependencies is using a different target version, I don't know how to fix this problem.

Answer 1

Add this to the very end of your build.gradle (Module:app):

configurations.all {
    resolutionStrategy.eachDependency { details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '27.1.1'
            }
        }

    }
}

Make sure that you replace '27.1.1' with the version of the android support library that you want to use for all the dependencies , it should not be lower than your complile sdk version

than re sync gradle

I found this answer in : here

Answer 2

try to change config in build.gradle, as below

configurations.all {

    resolutionStrategy {
        force 'com.android.support:design:27.0.2'
        force 'com.android.support:support-v4:27.0.2'
        force 'com.android.support:appcompat-v7:27.0.2'
    }
}

It makes forcefull changed to stated version, sometimes this is needed for signed apks

EDIT 1: The error which is shown in image, won't bother builiding apk.

The error here is of aapt2. By default aapt2 is enabled from gradle version 3.0+, you need to disable it by adding android.enableAapt2=false to gradle.properties file.

If it doesn't work, look for solution for aapt2 errors.

I have run build apk with above, by forcing support version as above, works fine for me, although error line didn't disappear

Answer 3

Change build.gradle to -> dependencies {

implementation 'com.android.support:appcompat-v7:27.1.1'

implementation 'com.android.support.constraint:constraint-layout:1.1.0'

}
