Android dependency has different version for the compile

Android dependency 'com.android.support:support-support-v4' has different version 
for the compile (23.1.1) and runtime (27.1.0) classpath. 
You should manually set the same version via DependencyResolution.

我这里是引用了不同版本的v4包造成的。
如果知道是哪个库引用的，一般用下面这个方法就可以

implementation("XXXXX") {
    exclude group: 'com.android.support', module: 'support-compat'
}

如果实在是不知道哪个Library引用的，可以用下面这个方法，放在project 的build.gradle 下

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion '27.1.0'//改这个版本号到你想要的版本
            }
        }
    }
}

具体位置示例

buildscript {

    dependencies {

    }
}
allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
        mavenCentral()
        maven { url 'https://maven.google.com' }
        google()
    }
}
subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion toolVersion
            }
        }
    }
}
