FirebaseApp中没有虚拟方法zzbzo（）Z；或者它的超类

2 月 Questions & Answers 2615

在我的安卓应用程序中，编译应用程序时出错。我在最新的安卓 studio中工作，使用Firebase UI Auth和Firebase数据库，所有版本都在同一个应用程序级别的文件中，那么为什么会出现此错误

错误：

    Process: com.example.varunwadhwa.myapplication, PID: 12383
    java.lang.NoSuchMethodError: No virtual method zzbqo()Z in class Lcom/google/firebase/FirebaseApp; or its super classes (declaration of 'com.google.firebase.FirebaseApp' appears in /data/app/com.example.varunwadhwa.myapplication-G6TbLS-JLKb6r1uvHa6XnQ==/split_lib_dependencies_apk.apk)

建造。梯度误差一切顺利。安卓支持库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。找到了版本28.0.0、27.1.0、27.0.2。例如com。安卓支持：动画矢量绘图：28.0.0和com。安卓支持：ExiFinInterface:27.1.0以下。。。(⌘F1）有些库、工具和库的组合是不兼容的，或者可能导致bug。其中一个不兼容之处是编译时使用的Android支持库版本不是最新版本（尤其是低于targetSdkVersion的版本）。问题id：GradleCompatible

构建。gradle（项目：我的应用程序）

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
