在proguard-rules.pro中加入以下代码，基本可以涵盖所有。（注意：#younghare注释部分是我的xposed插件配置，你可以不需要这部分代码）
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in D:\android_sdk\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 *;

studio中混淆代码时报错处理
Error:Execution failed for task ':app:transformClassesAndResourcesWithProguardForReleaseMinifyEnabled'.
> java.io.IOException: Please correct the above warnings first.
这个问题是在说你在混淆打包的时候有些类有可能找不着,所以会报错,和warning
解决的办法:
找到报warning的类都给他在你的proguard-rules.pro混淆器文件中
添加代码-dontwarn 包名+类名.**给取消掉warning就可以了,如果你不想那个类被混淆,那就添加代码:-keep class 包名+类名{*;}或者包名.**{*;}
-dontwarn org.dom4j.** -dontwarn org.bouncycastle.** -dontwarn org.apache.commons.logging.impl.** -keep class com.ObjBlockCipherParam{ *; } -keep class org.apache.commons.logging.impl.**{*;}
