Android混淆器"Can't find referenced"

Question

我想生成一个签名的 apk。但是我达到了 64k 方法的限制，所以我搜索了一些解决方案，其中之一是使用混淆器。我这样编辑 build.gradle：

 buildTypes {

        release {
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

    }

当我尝试生成签名的 apk 时，我收到了很多警告：

所以问题似乎出在我实现的存储库上。我读到我必须配置 proguard-rules.pro 文件，但我以前从未使用过它并且不知道语法。我该如何解决？

编辑依赖项：

compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:24.2.1'
    compile 'com.android.support:design:24.2.1'
    compile 'com.android.support:recyclerview-v7:24.2.1'
    compile 'com.android.support:cardview-v7:24.2.1'
    compile 'com.bignerdranch.android:expandablerecyclerview:2.1.1'
    compile 'com.github.lzyzsd:circleprogress:1.1.0@aar'
    compile 'com.github.PhilJay:MPAndroidChart:v2.2.3'
    compile 'net.qiujuer.genius:ui:1.5.2'
    compile 'com.akexorcist:RoundCornerProgressBar:2.0.3'
    compile 'com.rengwuxian.materialedittext:library:2.1.4'

Answer 1

buildTypes {

    release {
        debuggable false
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }


    debug {
        debuggable true
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

Answer 2

有两个有问题的库：

RoundCornerProgressBar

MPAndroidChart

第一个问题是 class com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar。有一个解决方案 here 可以解决这个问题，方法是添加到 Proguard：

-dontwarn com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar

第二个很简单，在Proguard中添加两条语句，库的作者明确描述here:

-keep class com.github.mikephil.charting.** { *; }
-dontwarn io.realm.**

您的 Proguard 文件应该包含这些行，问题应该会消失。
