Android-Studio-1.2.RC在Square的Okio库参考上的Proguard警告

Question

与Android Studio:1.2.RC

我在.gradle中启用了proguard:```

minifyEnabled=true

and added these rules to my proguard-rules.pro:

-dontwarn com.squareup.**
-dontwarn okio.**

and added these lint rules to my .gradle file:

warningsAsErrors false
abortOnError false
disable 'InvalidPackage'

```

但是当我尝试在调试模式下运行应用程序时,我仍然会收到这些警告:

```
Warning: okio.DeflaterSink: can't find referenced class org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
Warning: okio.Okio: can't find referenced class java.nio.file.Files

         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedclass)
:app:proguardDebug FAILED

```

这很奇怪,因为我还将这些规则/选项添加到依赖于OkHttp/Picasso的所有库模块中,我不知道哪里出错了,也许这是一个Android Studio错误？有没有人有这个问题的线索？

我在github上打开了一个问题.

Answer 1

您已禁用警告

-dontwarn com.squareup.**
-dontwarn okio.**

但是怎么样的包(如你发布的日志中所示)

-dontwarn org.codehaus
-dontwarn java.nio

无论哪种方式,忽略警告都不是一个好方法.

尝试保持这些类不被缩小:

-keep public class org.codehaus.**
-keep public class java.nio.**

天哪，我忘记为我的调试版本指定 proguard 文件，添加“proguardFiles”规则可以解决问题：

    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        debug {
            debuggable false
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            applicationIdSuffix ".debug"
        }
    }

有一次你费尽心思寻找钥匙，它就在你的口袋里。
