android - Android ProGuard 警告 - 找不到引用的类“com.zhihu.matisse.R$plurals”

Question

将 minifyEnabled 设置为 true 后无法生成签名的 APk。当设置 minifyEnabled 启用 false。我没有问题。是否必须将 minifyEnabled 设置为 true？没有什么问题？

我的 ProGuard 规则在这里..

-dontwarn com.squareup.picasso.**
 -dontwarn com.squareup.okhttp.internal.**
 -dontwarn org.apache.commons.logging.**
 -dontwarn okhttp3.internal.platform.*
 -dontwarn java.lang.invoke.*
 -dontwarn com.bumptech.glide.**

对于APK 的发布版本，强烈建议设置minifyEnabled为 true，这不仅可以最小化您的 apk 的最终大小，还可以帮助您将敏感的包/类混淆成一些混乱的代码形式，使其不会被逆向工程很容易。

根据您的错误信息如下：

com.zhihu.matisse.internal.model.SelectedItemCollection: can't find referenced class com.zhihu.matisse.R$plurals

Means you miss the R package references which usually is the resource class from the android aar library, i.e. the zhihu, check if you are including this lib properly.

Workaround for this problem is as below to find your own strings.xml and put below declaration to cheat proguard.

<plurals name="error_over_count">
        <item quantity="one">You can only select one media file</item>
        <item quantity="many">You can only select up to %1$d media files</item>
</plurals>

ss.com.bannerslider.adapters.SliderRecylcerViewAdapter: can't find referenced method 'void onBindImageSlideView(int,ss.com.bannerslider.viewholder.ImageSlideViewHolder)' in program class ss.com.bannerslider.adapters.SliderAdapter
ss.com.bannerslider.adapters.SliderRecylcerViewAdapter: can't find referenced field 'ss.com.bannerslider.SlideType CUSTOM' in program class ss.com.bannerslider.SlideType
ss.com.bannerslider.adapters.SliderRecylcerViewAdapter$2: can't find referenced field 'ss.com.bannerslider.SlideType CUSTOM' in program class ss.com.bannerslider.SlideType there were 2 unresolved references to classes or interfaces. there were 3 unresolved references to program class members. Exception while processing task java.io.IOException: Please correct the above warnings first.

Means you miss the onBindImageSlideView package references which usually is from other libraries, check if you are including that lib properly.
