Android 项目混淆系列2

项目上线时经常遇到要混淆的情况，上篇文章已经大概介绍了一些常见的坑，以及需要混淆的地方，这篇文章是对上篇的补充，也是最近碰到的一些坑。
首先，讲一下这次遇到的坑，就是环信的。开始已经按官方的混淆，结合网上的一些文章做的混淆，代码如下：
-dontwarn com.easemob.**
-keep class com.easemob.** {*;}
-keep class org.xmlpull.** {*;}
-keep class com.squareup.picasso.* {*;}
-keep class com.hyphenate.* {*;}
-keep class com.hyphenate.chat.** {*;}
-keep class org.jivesoftware.** {*;}
-keep class org.apache.** {*;}
如果使用easeui库，需要这么写
-keep class com.hyphenate.easeui.utils.EaseSmileUtils {*;}
2.0.9后加入语音通话功能，如需使用此功能的api，加入以下keep
-dontwarn ch.imvs.**
-dontwarn org.slf4j.**
-keep class org.ice4j.** {*;}
-keep class net.java.sip.** {*;}
-keep class org.webrtc.voiceengine.** {*;}
-keep class org.bitlet.** {*;}
-keep class org.slf4j.** {*;}
-keep class ch.imvs.** {*;}
-keep class com.easemob.** {*;}
环信3.0
-keep class com.hyphenate.** {*;}
-dontwarn com.hyphenate.**
但是在打包后，总是启动失败，这是很头疼的问题，可能大部分人会想到去写段代码去服务器看错误日志，这里教大家一个小技巧，其实我们不用那么麻烦，只需要用一个root的手机，把日志打开，同时在打包的时候也记得把自己项目的日志打开，在

输入自己的包名，然后就可以查看到报错信息了，之后我就发现是我的环信出了问题//初始化
EMClient.getInstance().init(this, options);
然后就在网上寻找答案，最后是发现还需要加一行混淆代码：

    -keep class com.superrtc.** {*;}

完整如下：

###-----------------环信-------------------#######-dontwarn  com.easemob.**-keep class com.easemob.** {*;}-keep class org.xmlpull.** {*;}-keep class com.squareup.picasso.* {*;}-keep class com.hyphenate.* {*;}-keep class com.hyphenate.chat.** {*;}-keep class org.jivesoftware.** {*;}-keep class org.apache.** {*;}#如果使用easeui库，需要这么写-keep class com.hyphenate.easeui.utils.EaseSmileUtils {*;}#2.0.9后加入语音通话功能，如需使用此功能的api，加入以下keep-dontwarn ch.imvs.**-dontwarn org.slf4j.**-keep class org.ice4j.** {*;}-keep class net.java.sip.** {*;}-keep class org.webrtc.voiceengine.** {*;}-keep class org.bitlet.** {*;}-keep class org.slf4j.** {*;}-keep class ch.imvs.** {*;}-keep class com.easemob.** {*;}#环信3.0-keep class com.hyphenate.** {*;}-dontwarn  com.hyphenate.**-keep class com.superrtc.** {*;}

问题解决~~

最后再教大家一个小技巧，当混淆时，有一些不知道混淆代码的包是，最简单的方法就是

-dontwarn org.apache**-keep class org.apache** { *;}

-dontwarn 包名**-keep class 包名 **  { *;}

基本都可以解决，以上就是我自己的一点项目总结，能力有限，不足之处，敬请拍砖~~，最后祝大家生活愉快！
