Firebase-UI库的Proguard配置 [英] Proguard configuration for Firebase-UI library

问题描述

创建启用了proguard的APK时，从Firebase-UI库（ com.firebaseui：firebase-ui：0.3.0 ）：



  java.lang.RuntimeException：java.lang.NoSuchMethodException：< init> [class android.view.View] 
 at com.firebase.ui.FirebaseRecyclerAdapter.onCreateViewHolder（FirebaseRecyclerAdapter.java:168）
  

调试版本（没有proguard）工作正常。谁有Firebase-UI的工作程序配置？

我目前的proguard配置看起来像这样（只有Firebase相关的部分）：

  -optimizationpasses 5 
 -keepattributes SourceFile，LineNumberTable，Exceptions，Signature，InnerClasses，* Annotation * 
 
 --keepnames class ** {*; } 
 
 -keep class com.firebase。** {*; } 
 -keepnames class com.fasterxml.jackson。** {*; } 
 -keepnames class javax.servlet。** {*; } 
 -keepnames class org.ietf.jgss。** {*; } 
  

解决方案

通过移动 ViewHolder 类被 FirebaseRecyclerAdapter 使用到一个专用包（例如com.mypackage.myapp.viewholders），并在proguard中添加一个规则配置，以防止这个包内的类被proguard混淆：

  -keep class com.mypackage.myapp.viewholders。** {*; } 
  

When creating a APK with proguard enabled, the following exception is thrown when using the FirebaseRecyclerAdapter from the Firebase-UI library (com.firebaseui:firebase-ui:0.3.0):

java.lang.RuntimeException: java.lang.NoSuchMethodException: <init> [class android.view.View]
                                                                              at com.firebase.ui.FirebaseRecyclerAdapter.onCreateViewHolder(FirebaseRecyclerAdapter.java:168)

The debug version (without proguard) works fine. Who has a working proguard config for Firebase-UI?

My current proguard config looks like this (only the Firebase related parts):

-optimizationpasses 5
-keepattributes SourceFile,LineNumberTable,Exceptions, Signature, InnerClasses,*Annotation*

-keepnames class ** { *; }

-keep class com.firebase.** { *; }
-keepnames class com.fasterxml.jackson.** { *; }
-keepnames class javax.servlet.** { *; }
-keepnames class org.ietf.jgss.** { *; }

解决方案

Solved this by moving the ViewHolder classes that are used by the FirebaseRecyclerAdapter to a dedicated package (e.g. com.mypackage.myapp.viewholders) and adding a rule within the proguard configuration to prevent that classes within this package become obfuscated by proguard:

-keep class com.mypackage.myapp.viewholders.** { *; }
