kotlin开发sdk混淆配置踩坑记录

问题1:使用代理by lazy延迟初始化成员变量，混淆后报错问题：

java.lang.AbstractMethodError: abstract method "java.lang.Object kotlin.jvm.functions.Function0.invoke()"
        at kotlin.SynchronizedLazyImpl.getValue(LazyJVM.kt:74)
        at com.ted.floo.connect.Session.getMSessionSet(Unknown Source:2)
        at com.ted.floo.connect.Session.addSessionListener(flooSDK:564)
        at com.ted.floo.service.ImUserService.<init>(flooSDK:59)
        at com.ted.floo.ImClient.<init>(flooSDK:25)
        at com.ted.floo.floodemo.MainActivity$client$2.invoke(MainActivity.kt:81)
        at com.ted.floo.floodemo.MainActivity$client$2.invoke(MainActivity.kt:28)
        at kotlin.SynchronizedLazyImpl.getValue(LazyJVM.kt:74)
        at com.ted.floo.floodemo.MainActivity.getClient(Unknown Source:2)
        at com.ted.floo.floodemo.MainActivity$login$1.run(MainActivity.kt:172)
        at java.lang.Thread.run(Thread.java:923)

解决方法：

-keep @kotlin.Metadata class *
-keepclasseswithmembers @kotlin.Metadata class * { *; }#主要是这一行代码其作用

 问题2:混淆后OKHttp内部类无法调用：

java.lang.AbstractMethodError: abstract method "okhttp3.Response okhttp3.Interceptor.intercept(okhttp3.Interceptor$Chain)"
        at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:142)
        at okhttp3.internal.http.RealInterceptorChain.proceed(RealInterceptorChain.java:117)
        at okhttp3.RealCall.getResponseWithInterceptorChain(RealCall.java:229)
        at okhttp3.RealCall$AsyncCall.execute(RealCall.java:172)
        at okhttp3.internal.NamedRunnable.run(NamedRunnable.java:32)
        at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167)
        at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641)
        at java.lang.Thread.run(Thread.java:923)

解决方法：

//*RetrofitClient$是你自定义的调用了自定义拦截器的类
-keepclasseswithmembers @kotlin.Metadata class com.ted.floo.connect.http.*RetrofitClient$*{
      *;
}

-dontskipnonpubliclibraryclassmembers
-dontskipnonpubliclibraryclasses
-dontoptimize
-allowaccessmodification

#保留行号
-renamesourcefileattribute flooSDK
-keepattributes SourceFile,LineNumberTable
-keepattributes Exceptions,InnerClasses,Signature,EnclosingMethod
#No prechecking
-dontpreverify

# 避免混淆注解
-keepattributes *Annotation*
# 避免混淆枚举的两个方法
-keepclassmembers enum * {
  public static **[] values();
  public static ** valueOf(java.lang.String);
