适用于Android支持库(v4& v7)的Proguard规则 [英] Proguard rules for Android support library (v4 & v7)

问题描述

我在我的应用中使用了android支持库v4和v7.我只使用了支持库中的几个小部件(不是全部).但是在最终版本的API中，支持库中包含18K函数. (附屏幕截图) 如何减少它们?

I use, android support library v4 and v7 in my app. I am using only few widgets from the support library (not all of them). But in final release API, 18K functions are included from support libraries. (screenshot attached) How to reduce them?

以下是我的proguard配置.

Following is my proguard config.

推荐答案

最后，我发现了使用proguard配置产生的问题.看起来Proguard会在我们的应用程序中自动添加这些规则.因此，我们不需要添加任何特定于android/google软件包的内容.除了以下几行，我删除了所有其他内容.

Finally I found out the problem I made with the proguard config. Looks like proguard automatically add these rules in our app. So we dont need to add anything specific for android/google packages. Except the following lines, I have removed everything else.

-optimizationpasses 5
-keepattributes SourceFile,LineNumberTable

对于所有第三方罐子，我们应该添加一条规则.如果第三方库来自Gradle，则有时他们会附带Proguard规则.

For all the 3rd party jars, we are supposed to add a rule. If the 3rd party library comes from Gradle, sometimes they have attached proguard rules along with it.
