您可以尝试清理项目，重新生成它。可能还可以。

1.尝试清除缓存并重新生成 在路径文件>清除缓存>清除缓存并重新启动

在应用程序级gradle中添加多索引支持 默认配置中的multudex true，如下所示

dexOptions{
javaMaxHeapSize“4g”
}
默认配置{
多索引启用真
}

添加multidexEnabled true后是否清除了缓存的可能重复项？另外添加'dexOptions{javaMaxHeapSize“4g”}@uwaisaleem请检查编辑的答案希望它有助于我在添加multidexEnabled后清除缓存，并且dexoption已经添加了javaMaxHeapSize“3g”，但在使其成为4g之后，我收到了相同的错误和一些其他错误。请尝试删除应用插件：“com.google.gms.google services”。删除应用插件“com.google.gms.google services”后，它可能与其他库发生冲突。相同的问题是：“com.google.gms.google services”
