启用proguard后，Realm中的ClassNotFoundException

Question

I am getting an exception:

Caused by: java.lang.ClassNotFoundException: Didn't find class "io.realm.Realm"

In build.gradle minifyEnabled true.

proguard-rules.pro:

-keep class io.realm.annotations.RealmModule

-keep @io.realm.annotations.RealmModule class *

-keep class io.realm.internal.Keep

-keep @io.realm.internal.Keep class *

-dontwarn javax.**

-keep class io.realm.{ *; }

-keepnames public class * extends io.realm.RealmObject

-keep public class * extends io.realm.RealmObject { *; }

Any idea?

It seems that you'll have to replace this rule:

-keep class io.realm.{ *; }

With this one:

-keep class io.realm.** { *; }

Everything else that starts with io.realm can then be removed.

Why? The first rule you have here is invalid. The second one will keep everything in io.realm including any sub-packages, methods and fields. This means that it will override all of the other rules.
