Retrofit: Enhancement: retrofit proguard rules

[gengjiawen]

For now the progurad rules in http://square.github.io/retrofit/ won't work correctly if you are using proguard-android-optimize.
We need add this to make it work.

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

For more information please see http://stackoverflow.com/questions/35506111/retrofit-2-not-sending-data-when-proguard-is-enabled.

Your rule will prevent methods from being obfuscated which is unnecessary and also unused methods will be kept. This one should be more optimal:

-keepclassmembernames,allowobfuscation interface * {
    @retrofit2.http.* <methods>;
}

It'll stop ProGuard from removing parameters but allow proper obfuscation and shrinking.

Nothing is working

[henrychao24]

Android Studio builded failed if adding following proguard options:
-keepclassmembernames,allowobfuscation interface * { @retrofit2.http.* <methods>; }

No modifier should be added following keepclassmembernames as the manual writes below:

@HenryChao24 怎么解决 我也遇到了 这个链接404了

[henrychao24]

@joker-fu
It's a workaround below.
-keepclassmembers,allowshrinking,allowobfuscation interface * { @retrofit2.http.** <methods>; }

Please use in this lines Dexguard-project.txt file. that's all. Enjoy your coding...

Retrofit

-keep class retrofit.* { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepclasseswithmembers class * {
@retrofit2.http. ;
}
-keepclasseswithmembers interface * {
@retrofit2.http.* ;
}
-dontwarn javax.annotation.Nullable
-dontwarn javax.annotation.ParametersAreNonnullByDefault
-dontobfuscate
-dontoptimize
-dontshrink

No. Those rules are crazy. You're much better off disabling Dexguard than using those rules.
