Android Proguard问题

Question

我一直在使用android jetpack，调试工作完全正常，但是一旦我尝试建立启用minify的签名apk，我就面临此问题

java.lang.NoClassDefFoundError: Failed resolution of: Lq0;
    at java.lang.Class.getDeclaredFields(Native Method)
    at com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.a(SourceFile:10)

保护规则如下

-dontnote

-dontskipnonpubliclibraryclasses

-forceprocessing

-optimizationpasses 5

-assumenosideeffects class android.util.Log {
   public static boolean isLoggable(java.lang.String, int);
   public static *** d(...);
   public static *** v(...);
   public static *** i(...);
   public static *** w(...);
   public static *** e(...);
}

-assumenosideeffects class com.highorbit.jobseeker.util.helperUtils.Logger {
   public static *** d(...);
   public static *** e(...);
}

-dontwarn retrofit2.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-dontwarn javax.annotation.**
-dontwarn java.nio.file.*
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
-dontwarn okio.**
-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}
-keepclasseswithmembers interface * {
    @retrofit2.http.* <methods>;
}
-keep class sun.misc.Unsafe { *; }
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer

-keepclassmembers enum * { *; }
-keepclassmembers enum * { *; }

-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable

-keep public class * extends java.lang.Exception

-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**


-keep class * extends androidx.fragment.app.Fragment{}

另外，我无法解决的另一件事是，我无法获取崩溃的确切文件名和行号。我已经为crashlytics添加了所有proguard规则，但仍然没有成功

Answer 1

// all classes in a package
-keep class com.example.app.json.** { *; }
// or a specific class
-keep class com.example.app.json.SpecificClass { *; }
