带有 ProGuard 的 Firebase
Posted
技术标签:
【中文标题】带有 ProGuard 的 Firebase【英文标题】：Firebase with ProGuard 【发布时间】：2019-02-13 18:18:30 【问题描述】：我正在使用 firebase 制作一个应用程序，它运行良好。 直到我打开 ProGuard 甚至 R8。
我基本上尝试了我在互联网上找到的所有 ProGuard 规则组合，我什至尝试过
-keep class com.firebase.** *;
-keep class mypackage.** *;
我有完全相同的项目，只是代码结构不同，它确实可以完美地使用以下规则：
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep public class * extends java.lang.Exception
-keepattributes Signature
-keepclassmembers class com.tritrio.anabi2y.model.** *;
-keep public class * implements com.bumptech.glide.module.GlideModule
-keep public class * extends com.bumptech.glide.module.AppGlideModule
-keep public enum com.bumptech.glide.load.ImageHeaderParser$**
**[] $VALUES;
public *;
-dontwarn com.firebase.ui.auth.**
这里是 StackTrace：

【问题讨论】：
【参考方案1】：R8 是罪魁祸首。
禁用后一切正常。
我已将问题报告给 google 和 firebase。
【讨论】：
救命！我花了几个小时在这个【参考方案2】：你应该使用官方Quickstart Samples中的规则
这些通常是 firebase android 库的规则
-keepattributes EnclosingMethod
-keepattributes InnerClasses
-dontwarn org.xmlpull.v1.**
-dontnote org.xmlpull.v1.**
-keep class org.xmlpull.** *;
-keepclassmembers class org.xmlpull.** *;
【讨论】：
我已经发布了解决方案。我试过了，没用，谢谢解答。以上是关于带有 ProGuard 的 Firebase的主要内容，如果未能解决你的问题，请参考以下文章
