使用android.support.v4.app蜂窝兼容包导出签名的应用程序时出现Proguard错误

Question

我在我的项目中使用v4兼容包,但是当我尝试导出已签名的应用程序时,我从Proguard收到以下消息.我整个晚上都用Google搜索,但我找不到解决这个问题的答案.

Answer 1

看起来android.support.v4中的一些clases与android中的某些类不完全兼容.如果您确定这不是问题,您可以指定

-dontwarn android.support.v4.**

然后,ProGuard将忽略这些问题并继续处理代码.

请参阅ProGuard手册>故障排除>警告:找不到引用的字段/方法

Answer 2

这就是我在proguard.cfg中使用的内容:

-dontwarn **CompatHoneycomb
-keep public class * extends android.support.v4.app.Fragment

更一般的是:

-dontwarn **CompatHoneycomb
-keep class android.support.v4.** { *; }

但它会导致更大的APK大小,所以只有在第一个不起作用时才使用.
