Android-Studio-1.2.RC-Proguard-warning-on-Square'；s Okio图书馆参考

使用Android Studio:1.2.RC

我在gradle中启用了proguard： ```

并将这些规则添加到我的proguard-rules.pro中：

并将这些lint规则添加到我的.gradle文件中：

```

但当我尝试在调试模式下运行应用程序时，仍会收到以下警告：

```

```

这太奇怪了，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，我不知道哪里出了问题，也许这是Android Studio的错误？有人对这个问题有任何线索吗

我已在github上打开了一个。您已禁用对的警告

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

但是对于包（如您发布的日志中所示）又如何呢

不管怎样，忽略警告都不是一个好方法

尝试避免将这些类缩小为这样：

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

哦，天哪，我忘了为我的调试构建指定proguard文件，添加“proguardFiles”规则可以解决这个问题：

    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"
        }
    }

其中一个时刻，你努力寻找钥匙，钥匙就在你的口袋里。

你可以忽略这些警告。同样的事情也发生在我身上。我的默认proguard文件名是“proguard android.txt”，我正在“proguard rules.pro”中编写规则。

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

-dontwarn org.codehaus
-dontwarn java.nio

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

    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"
        }
    }
