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：

```

         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.

```

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Android Studio的错误？有没有人有这个问题的线索？

我在github上打开了issue。

Answer 1

您已禁用

的警告

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

但是对于包（如发布的日志中所示）

-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.**

哦基督，我忘了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"
        }
    }

你努力寻找钥匙的那一刻，它就在你的口袋里。
