Android 混淆问题记录can't find superclass or interface

今天用了AS混淆项目，工程使用了fastjson解析数据，混淆出现以下问题：

然后网上查找一下，发现都说加上-keep class javax.ws.rs.* { ; }

和-ignorewarnings就可以了

#忽略警告
-ignorewarnings
-keep class javax.ws.rs.** { *; }
-dontwarn com.alibaba.fastjson.**
-keep class com.alibaba.fastjson.** { *; }

然后发现也不行，一直在混淆中，1个小时过去提示：

PSI and index do not match:PSI and index do not match

又按网上说的Invalidate Caches/Restart…

还是不行！



后面发现build.gradle配置的问题！！！

getDefaultProguardFile(‘proguard-android.txt’), “proguard-rules.pro”

一定要加一个”proguard-rules.pro”，之前一直把混淆放在proguard-android.txt：getDefaultProguardFile(‘proguard-android.txt’)。

proguard-rules.pro名字可以随便取，然后把混淆放里面！

buildTypes {
release {
buildConfigField "boolean", "LOG_DEBUG", "false"  // 不显示Log
minifyEnabled true  // 混淆
//            shrinkResources true // 移除无用的resource文件
proguardFiles getDefaultProguardFile('proguard-android.txt'), "proguard-rules.pro"
signingConfig signingConfigs.release
//            defaultConfig {
//            }
}
debug {
buildConfigField "boolean", "LOG_DEBUG", "true"  // 显示Log
signingConfig signingConfigs.debug
//            defaultConfig {
//            }
}
}
