Android Proguard「找不到引用」

Question

我想生成已簽名的apk。但我達到了64k的方法限制，所以我搜索了一些解決方案，其中一個是使用proguard。 我編輯的build.gradle這樣的：

buildTypes { 

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

    } 

當我再嘗試生成APK簽署我得到了很多的警告：

所以，問題似乎是我實現了資源庫。我讀過，我必須配置proguard-rules.pro文件，但我從來沒有使用過，並不知道語法。 我該如何解決這個問題？

EDIT 依賴關係：

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'

Answer 1

有兩個問題的庫：

RoundCornerProgressBar

MPAndroidChart

第一個問題是與類com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar。有克服這個問題，通過向Proguard的一個解決方案here：

-dontwarn com.akexorcist.roundcornerprogressbar.TextRoundCornerProgressBar 

第二個是簡單地通過增加兩個語句解決了ProGuard的，該庫的作者清楚地描述here：

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

您的Proguard文件應該包含這些行，問題應該消失。
