启用ProGuard时HttpResponse发生崩溃问题求助

问题 #

启用ProGuard后，HttpResponse出现崩溃，抛出java.lang.IncompatibleClassChangeError错误，核心原因是Firebase Performance监控工具类尝试将org.apache.http.message.BufferedHeader当作org.apache.http.NameValuePair接口调用getValue()方法，但该类并未实现该接口。

错误信息 #

java.lang.IncompatibleClassChangeError: Class 'org.apache.http.message.BufferedHeader' does not implement interface 'org.apache.http.NameValuePair' in call to 'java.lang.String org.apache.http.NameValuePair.getValue()' (declaration of 'com.google.firebase.perf.network.NetworkRequestMetricBuilderUtil' appears in /data/app/~~mWC7wl-mdiulxrPqJH3MXg==/com.vendsy.tray-5-xmP-bIr7MJZJOfz9feYA==/base.apk) 
at com.google.firebase.perf.network.NetworkRequestMetricBuilderUtil.getApacheHttpResponseContentType(NetworkRequestMetricBuilderUtil.java:62) 
at com.google.firebase.perf.network.FirebasePerfHttpClient.execute(FirebasePerfHttpClient.java:200) 
at com.google.firebase.perf.network.FirebasePerfHttpClient.execute(FirebasePerfHttpClient.java:48)

已尝试的ProGuard规则（未解决） #

-keep class org.apache.http.HttpResponse { *; }
-dontwarn org.apache.http.**
-keep class com.google.firebase.perf.network.** {*;}
-dontwarn com.google.firebase.perf.network.**

解决方案 #

添加以下ProGuard规则，确保Apache Http核心类、接口及Firebase Perf相关类不被混淆或优化：

# 保留所有Apache Http类和接口，避免结构被修改
-keep class org.apache.http.** { *; }
-keep interface org.apache.http.** { *; }
-dontwarn org.apache.http.**

# 保留Firebase Perf网络监控类
-keep class com.google.firebase.perf.network.** { *; }
-dontwarn com.google.firebase.perf.network.**

# 明确保留引发错误的类和接口，防止ProGuard误优化
-keep class org.apache.http.message.BufferedHeader { *; }
-keep interface org.apache.http.NameValuePair { *; }

说明 #

错误根源是ProGuard在混淆过程中，可能删除或修改了NameValuePair接口与BufferedHeader类的关联结构，导致Firebase Perf代码调用时出现类型不兼容。之前的规则仅覆盖了HttpResponse和Firebase类，未包含关键的NameValuePair接口和BufferedHeader类，补充后即可解决类型转换错误。
