请参考： -keep class com.jeremyliao.livedatabus.* { ; } -dontwarn com.jeremyliao.livedatabus.**

由于以下部分使用了反射获取mObservers、mVersion及mLastVersion，所以不能混淆android.arch.lifecycle.LiveData及android.arch.lifecycle.LiveData.ObserverWrapper

        private void hook(@NonNull Observer<T> observer) throws Exception {
            //get wrapper's version
            Class<LiveData> classLiveData = LiveData.class;
            Field fieldObservers = classLiveData.getDeclaredField("mObservers");
            fieldObservers.setAccessible(true);
            Object objectObservers = fieldObservers.get(this);
            Class<?> classObservers = objectObservers.getClass();
            Method methodGet = classObservers.getDeclaredMethod("get", Object.class);
            methodGet.setAccessible(true);
            Object objectWrapperEntry = methodGet.invoke(objectObservers, observer);
            Object objectWrapper = null;
            if (objectWrapperEntry instanceof Map.Entry) {
                objectWrapper = ((Map.Entry) objectWrapperEntry).getValue();
            }
            if (objectWrapper == null) {
                throw new NullPointerException("Wrapper can not be bull!");
            }
            Class<?> classObserverWrapper = objectWrapper.getClass().getSuperclass();
            Field fieldLastVersion = classObserverWrapper.getDeclaredField("mLastVersion");
            fieldLastVersion.setAccessible(true);
            //get livedata's version
            Field fieldVersion = classLiveData.getDeclaredField("mVersion");
            fieldVersion.setAccessible(true);
            Object objectVersion = fieldVersion.get(this);
            //set wrapper's version
            fieldLastVersion.set(objectWrapper, objectVersion);
        }
    }

所以混淆规则为：

-dontwarn android.arch.lifecycle.LiveData
-keep class android.arch.lifecycle.LiveData { *; }

这个写在README里面吧， @JeremyLiao ，我也踩了这个坑

混淆规则为： -dontwarn android.arch.lifecycle.LiveData -keep class android.arch.lifecycle.LiveData { ; } -keep class android.arch.lifecycle.LifecycleRegistry { ; } -keep class android.arch.core.internal.SafeIterableMap { *; }

好的，多谢提醒

因为Android对反射加强管理了，版本兼容容易出现问题，所以一直不太希望代码中过多的使用反射去实现功能，所以这几天参考作者的思路对项目进行了重构，重构基于作者的两个项目进行了合并，如有好的建议欢迎大家一起讨论

混淆怎么配置？ #8
