关于AndroidStudio混淆打包 proguard-rules.pro 的配置

最近在搭建一个APP的时候，使用了混淆打包的方式，然后发现死活打包不上。后来求爷爷告奶奶才搞正常了，这里记录一下，其实关键点就是在这个 proguard-rules.pro 文件里面 ，一下是我自己的配置，大家看着，就知道怎么配置了。

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\Android\sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}
-dontusemixedcaseclassnames  
-dontskipnonpubliclibraryclasses  
-verbose  
-ignorewarnings 

-dontshrink  
#指定代码的压缩级别  
-optimizationpasses 5  

#包明不混合大小写  
-dontusemixedcaseclassnames  

#不去忽略非公共的库类  
-dontskipnonpubliclibraryclasses  

 #优化  不优化输入的类文件  
-dontoptimize  

 #不做预校验  
-dontpreverify  

 #混淆时是否记录日志  
-verbose  

 # 混淆时所采用的算法  
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*  

#保护注解  
-keepattributes *Annotation*  

# 保持哪些类不被混淆  
-keep public class * extends android.app.Fragment  
-keep public class * extends android.app.Activity  
-keep public class * extends android.app.Application  
-keep public class * extends android.app.Service  
-keep public class * extends android.content.BroadcastReceiver  
-keep public class * extends android.content.ContentProvider  
-keep public class * extends android.app.backup.BackupAgentHelper  
-keep public class * extends android.preference.Preference  
-keep public class com.android.vending.licensing.ILicensingService  
#如果有引用v4包可以添加下面这行  
-keep public class * extends android.support.v4.app.Fragment  

#-keeps
-keepattributes Signature, Annotation
-keep class com.google.gson.** {*;}
#-keep class sun.misc.Unsafe { *; }
-keep class okhttp3.** { *; }
-keep class okio.** { *; }
-keep class com.alibaba.** { *; }
-keep class retrofit2.** { *; }

#忽略警告  
-ignorewarning  

##记录生成的日志数据,gradle build时在本项目根目录输出##  

#apk 包内所有 class 的内部结构  
-dump class_files.txt  
#未混淆的类和成员  
-printseeds seeds.txt  
#列出从 apk 中删除的代码  
-printusage unused.txt  
#混淆前后的映射  
-printmapping mapping.txt
