is also present at [com.android.support:appcompat-v7:25.3.1] AndroidManifest.xml:27:9-31 value=(25.3.1).

Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml:22:5-24:41 to override.

Attribute meta-data

解决办法：

configurations.all {

    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == 'com.android.support') {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion '25.3.0'//默认使用的版本
            }
        }
    }
}

在自己app的build.gradle最后加上上面这段话
