Android 生成Release版本时，混淆问题的解决

今天在生成release版本的apk时，出现了编译失败，百度以后，发现是混淆配置出现错误

Warning:com.squareup.picasso.OkHttpDownloader: can't find referenced class Warning:com.squareup.picasso.OkHttpDownloader: can't find referenced class com.squareup.okhttp.Request
                  .........
    Warning:okio.Okio: can't find referenced class java.nio.file.Files Warning:okio.Okio: can't find referenced class java.nio.file.Path
                .........
    Warning:rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef: can't find referenced class sun.misc.Unsafe Warning:rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef: can't find referenced

从上面的log中可以看到有三个包配置不正确，第一个是okhttp,第二个是okio,第三个是rx,打开app下proguard-rules.pro，配置如下内容，便可以编译成功。

## okhttp ##

# okhttp
    -keepattributes SourceFile,LineNumberTable -keep class com.parse.*{ *; } -dontwarn com.parse.** -dontwarn com.squareup.picasso.** -keepclasseswithmembernames class * {     native <methods>;
    }

## okio ##

# Okio
    -dontwarn com.squareup.**
    -dontwarn okio.**
    -keep public class org.codehaus.* { *; }
    -keep public class java.nio.* { *; }

## rx ##

# RxJava RxAndroid
    -dontwarn sun.misc.**
    -keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* {
        long producerIndex;
        long consumerIndex;
    }
    -keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef {
        rx.internal.util.atomic.LinkedQueueNode producerNode;
    }
    -keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef {
        rx.internal.util.atomic.LinkedQueueNode consumerNode;
    }

通过如上配置，可以正常生成release版本的apk了。以后出现类似的问题，只要找到对应的混淆规则添加，就可以了。。。希望对大家有用，下一篇文章，我会整理一下一些实用频率很高的混淆配置。
