android - 类未找到异常 : unable to find class "android.support.v4.util.ArrayMap"

Question

我的应用程序的签名 apk 在高于 5.0.1 的 android 版本上运行，但我面临这个问题，我的应用程序在 5.0.1 版本上启动应用程序后立即崩溃，这是我得到的错误 - 引起:java.lang.ClassNotFoundException:在路径上找不到类“android.support.v4.util.ArrayMap”:DexPathList[[zip 文件“/data/app/com.*****1/base.apk"],nativeLibraryDirectories=[/vendor/lib,/system/lib]]

请注意，当我使用 android studio 运行时，该应用程序不会崩溃，但当我运行已签名的 apk 时，它会崩溃。 我不知道该怎么办，我已经经历了很多 stackoverflow 问题，但没有发现可以解决我的问题。这是我的 app.gradle 文件 -

这是我的build.gradle(项目级别)

buildscript {

allprojects {

        }

    }

Answer 1

如果 gradle 版本是 3.x.x 尝试添加 maven { url 'https://maven.google.com' } 到

allprojects {
    repositories {
        //add here
    }
}

代替 google() 和同步 gradle。它应该有所帮助。您可以使用 this link 查看它们之间的区别.
