Question

大家都在更改build.gradle属性后minifyEnabled true我收到了以下错误。我读过如果我们使用minifyEnabled true那么

The ProGuard tool shrinks, optimizes, and obfuscates your code by removing unused code and renaming classes, fields, and methods with semantically obscure names. The result is a smaller sized .apk file that is more difficult to reverse engineer

我想使用上述好处。

如何解决此问题。任何建议将不胜感激。提前谢谢。

您需要找到一个带有proguard规则的文件（默认情况下为proguard-rules.pro），并为其添加以下行：

-keep class butterknife.** { *; }
-dontwarn butterknife.internal.**
-keep class **$$ViewInjector { *; }

-keepclasseswithmembernames class * {
    @butterknife.* <fields>;
}

-keepclasseswithmembernames class * {
    @butterknife.* <methods>;
}

-keepattributes *Annotation*,EnclosingMethod,Signature
-keepnames class com.fasterxml.jackson.** { *; }
 -dontwarn com.fasterxml.jackson.databind.**
 -keep class org.codehaus.** { *; }
 -keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
 public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *; }
-keep public class your.class.** {
  public void set*(***);
  public *** get*();
}

-dontwarn com.squareup.okhttp.**

your.class替换为序列化/反序列化的那个。

这可能不足以消除所有与proguard相关的错误，但有些事情要开始。

正如@Deividi Cavarzan所指出的，如果您使用其他库，我建议您搜索他们推荐的proguard设置以避免进一步的问题。如果不存在这样的配置，但您仍然可以尝试从库的类中获取错误：

-keep class com.[library package].** {*;}。

此外，并非所有的proguard副作用都是在构建时捕获的，您可以轻松地将缩小版本与运行时错误一起崩溃，其中调试版本可以顺利运行，因此之后需要进行测试。

minifyEnabled true生成许多警告
