警告说如果或者，您可能必须指定选项 -dontskipnonpubliclibraryclassmembers

这是我的 proguard.cfg

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper

-keepclasseswithmembernames class * {

-keepclasseswithmembers class * {

}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {

    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

【问题讨论】：

  • 通过在 proguard.cfg 上添加 -dontwarn android.support.v4.** -dontwarn com.google.android.gms.** 解决

标签： android proguard


【解决方案1】：

这就是我在我的 proguard 中为 android 支持所做的事情

#########--------Android Support--------#########
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-dontwarn android.support.**

如控制台日志中指向ProGuard Troubleshooting page 的链接所示，您应该将 project.properties 中的目标更改为包含缺失类的目标。在这种情况下：“android-18”或者可能是“Google Inc.:Google APIs:18”。

您仍然可以在 AndroidManifest.xml 中指定不同的 minSdkVersion。

您不应指定任何 -libraryjars 选项，因为 Android 构建过程已经为您指定了这些选项——您现在只会看到有关重复类的警告。事实上，Android 构建过程也为您指定了大多数其他选项。

【讨论】：

  • 如果它不起作用，可能是你的 gradle 有问题。如果设置正确，请检查你的 android 版本、minSdkVersion、android 依赖项
【解决方案2】：

尝试将此行添加到您的 proguard 文件中：

-dontwarn android.support.v4.**

【讨论】：

  • 你确定你有同样的错误吗？ @SiriusKuddo
  • 是的，但是在我添加后 -dontwarn com.google.android.gms.** 警告错误消失了
  • 干得好！ @SiriusKuddo
