java.lang.NoClassDefFoundError（解析失败：Lcom / google / android / gms / common / internal / zzbp）

一身转战三千里，一剑曾当百万师。这篇文章主要讲述java.lang.NoClassDefFoundError：解析失败：Lcom / google / android / gms / common / internal / zzbp相关的知识，希望能为你提供帮助。
我不明白这里出了什么问题。我一直在寻找修复，但我找不到任何东西。谁知道什么是错的？

答案这可能是因为您尚未启用多索引。您需要向gradle添加以下依赖项。

implementation 'com.android.support:multidex:1.0.3'

并在multiDexEnabled true中设置defaultConfig以打开多索引。
另一答案如果app支持的android版本低于20 [minSdkVersion 19]，这些库需要Multidex。
Enable Mutidex
试试这个，它会起作用。
另一答案要解决此问题，请更改以下实现：

implementation 'com.google.firebase:firebase-core:16.0.1' implementation 'com.google.firebase:firebase-firestore:11.4.2' implementation 'com.google.firebase:firebase-auth:16.0.1' implementation "com.google.android.gms:play-services-base:15.0.1" implementation "com.google.android.gms:play-services-gcm:15.0.1"

至

implementation 'com.google.firebase:firebase-core:16.0.7' implementation 'com.google.firebase:firebase-firestore:18.0.0' implementation 'com.google.firebase:firebase-auth:16.1.0' implementation "com.google.android.gms:play-services-base:16.1.0" implementation "com.google.android.gms:play-services-gcm:16.0.0"

在您的顶级build.gradle文件中，请务必使用最新版本的Google Service插件：
