java - 由于没有 @Subcribe 方法，Android EventBus 应用程序在 Release模式下崩溃

Question

该应用程序可以在调试中运行，但不能在发布中运行

这是我的 gradle 文件:https://gist.github.com/rubenwardy/b467d1efd79c671f9a932d98768ff656
这是我的混淆器文件:

-keep class com.androidplot.** { *; }
# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on RoboVM on iOS. Will not be used at runtime.
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions

-keepattributes *Annotation*
-keepclassmembers class ** {
    @org.greenrobot.eventbus.Subscribe <methods>;
}
-keep enum org.greenrobot.eventbus.ThreadMode { *; }

-keepclassmembers class com.rubenwardy.** { *; }

如果我用以下内容替换 proguard，错误仍然发生:

-dontoptimize
-dontshrink
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

我在 MainActivity 中肯定有 @Subscribe 函数:

@Subscribe
protected void onPeriodChange(final Events.PeriodChangeRequestedEvent e) {
    Log.e("MAct", "Period " + e.from.toString() + " to " + e.to.toString());
    filter = new TransactionFilter() {
        @Override
        public boolean isAllowed(Transaction transaction) {
            return transaction.created.getTime() > e.from.getTime() &&
                    transaction.created.getTime() < e.to.getTime();
        }
    };

    filterTransactions();
}

我已经，ofc，用谷歌搜索了这个 - 但找不到任何结果。请询问您是否需要更多信息。

事实证明 @Subscribe 方法需要公开。

@Subscribe
public void onPeriodChange(final Events.PeriodChangeRequestedEvent e) {
    Log.e("MAct", "Period " + e.from.toString() + " to " + e.to.toString());
    filter = new TransactionFilter() {
        @Override
        public boolean isAllowed(Transaction transaction) {
            return transaction.created.getTime() > e.from.getTime() &&
                    transaction.created.getTime() < e.to.getTime();
        }
    };

    filterTransactions();
}
