这是您的gradle中存在重复或可传递依赖项的情况。要检查复制是从何处产生的，请始终首先构建依赖关系树

这是通过

allDependencies

gradle任务完成的。在Android Studio的右侧栏上，单击Gradle>app>Tasks>Android>androidDependencies。gradle控制台现在将以

在这里，检查树中任何地方是否存在冲突的库版本。 排序后，您可以通过以下方式排除冲突的DEP

compile("com.crashlytics.sdk.android:crashlytics:2.5.1") {
            transitive = true
            exclude group: "com.android.support" // Conflicting dep removed here
