What is the correct proguard?

Hi, team, when my project is using StateSaver in Activity/Fragment, it’s fine, because default proguard will keep the name for system views. but when I use for custom file, it can not find injector because of obfuscate.

I check the README, it shows This library comes with a ProGuard config. No further steps are required, but all necessary rules can be found here.

I checked the sample, it’s

-dontwarn com.evernote.android.state.**
-keep class com.evernote.android.state.** { *; }
-keep class **$$StateSaver { *; }
-keepclassmembers class * {
    @com.evernote.android.state.StateReflection <fields>;
}

it will keep the generate class, but it won’t keep the class with @State annotation, I don’t know what is StateReflection.

then I change it to

-dontwarn com.evernote.android.state.**
-keep class com.evernote.android.state.** { *; }
-keep class **$$StateSaver { *; }
-keepclasseswithmembernames class * {
    @com.evernote.android.state.* <fields>;
 }
-keepnames class * { @com.evernote.android.state.State *;}

it works.

Yes, the rule -keepnames class * { @com.evernote.android.state.State *;} seems to be necessary. Good catch!

The downside is that this rule also preserves the variable names, although they could be obfuscated. But I didn’t find a proguard rule that only keeps the class name and not variable names although they’re matching.
