解决Android支持库版本冲突-优快云博客

本文介绍了一种解决Android项目中因使用不同版本的支持库而引发的构建错误的方法。通过在Gradle配置文件中设置统一的支持库版本，可以避免此类问题。

导入
implementation ‘com.jakewharton.rxbinding2:rxbinding-recyclerview-v7:2.1.1’
包后就报错，
这里写图片描述
错误是『『All com.android.support libraries must use the exact same version specification 』』

解决方法：

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '28.0.0-alpha3'
            }
        }
    }
}
dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
    //implementation 'com.android.support:recyclerview-v7:26.+'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
    implementation 'com.jakewharton.rxbinding2:rxbinding-recyclerview-v7:2.1.1'
}
