MODEL 类中的变量名称重复，在 ANDROID STUDIO 中完成混淆时出错



我正在学习混淆我的Android代码，方法是在我的清单文件中制作：minifyEnabled = true。

但是GSON在混淆代码方面存在一些问题。 我试过：

  1. 混淆不应重命名我的模型类和模型类变量。
  2. 在模型类的每个变量上添加了@SerializedName。

但是错误说，我的模型类中有名为 a 的重复变量。 但是我的 Object 类中没有任何重复变量。

build.gradle

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

以下是我的专业保护文件：

proguard-rules.pro

-ignorewarnings
-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
-keepattributes SourceFile,LineNumberTable
-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**
# Gson specific classes
-dontwarn sun.misc.**
# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }
-keep class com.hgs.ruralhealth_new.model.** { *; }
-keep class com.hgs.ruralhealth_new.model.* { *; }
-keep class com.hgs.ruralhealth_new.model.masterdata.* { *; }
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer
-keep class com.hgs.ruralhealth_new.model.** { <fields>; }
-keep class com.hgs.ruralhealth_new.model.masterdata.** { <fields>; }
-keep class com.hgs.ruralhealth_new.model.register.** { <fields>; }
-keep class com.hgs.ruralhealth_new.model.** { *; }
-keep class com.hgs.ruralhealth_new.model.masterdata.** { *; }
-keep class com.hgs.ruralhealth_new.model.register.RegistrationInputData
-keepclassmembers class com.hgs.ruralhealth_new.model.** { *; }
-keepclassmembers class com.hgs.ruralhealth_new.model.masterdata.** { *; }
-keepclassmembers class com.hgs.ruralhealth_new.model.register.** { *; }
-keepclassmembers class com.hgs.ruralhealth_new.model.register.RegistrationInputData
-keepclassmembers enum * { *; }

错误如下：

当我在 Proguard 中复制此错误时，在下面的输出中：

现在登录活动的代码是什么.java：457

public void onResponse(Call<PhysiotherapistResponse> call, Response<PhysiotherapistResponse> response) {
Log.i("Physio Backup==>", new Gson().toJson(response));//This is line 457

以下是我的模型类：

物理治疗师反应.java

public class PhysiotherapistResponse implements Parcelable {
@SerializedName("status")
private String status;
@SerializedName("message")
private String message;
@SerializedName("syncFromId")
private String syncFromId;
@SerializedName("syncToId")
private String syncToId;
@SerializedName("data")
private List<PhysiotherapistInputData> data;
//////////................GETTERS SETTERS GOES BELOW...........

物理治疗师输入数据.java

public class PhysiotherapistInputData implements Parcelable {
@SerializedName("createdDate")
private String createdDate;
@SerializedName("swpNo")
private String swpNo;
@SerializedName("patientName")
private String patientName;
@SerializedName("age")
private String age;
@SerializedName("gender")
private String gender;
@SerializedName("namePhysio")
private String namePhysio;
@SerializedName("painScore")
private String painScore;
@SerializedName("exercieAdvice")
private String exercieAdvice;
@SerializedName("remark")
private String remark;
@SerializedName("isOld")
private String isOld;
@SerializedName("doctorId")
private int doctorId;
//////////................GETTERS SETTERS GOES BELOW...........

将遵循Proguard规则添加到您的ProGuard文件中，它来自这里

-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
# Gson specific classes
-dontwarn sun.misc.**
#-keep class com.google.gson.stream.** { *; }
# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.** { *; }
# Prevent proguard from stripping interface information from TypeAdapterFactory,
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter)
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer
