MODEL类中的变量名称重复，在ANDROID STUDIO中进行混淆处理时出错

标签： android gson obfuscation

我正在通过在清单文件中使minifyEnabled = true来混淆我的Android代码。

但是GSON的混淆代码存在一些问题。 我尝试过：

  1. 迷惑不应该重命名我的Model类和Model类变量。
  2. 在Model类的每个变量上添加@SerializedName。

但是错误提示，我的Model类中有重复的变量，名为a。 但是我的Object类中没有任何重复的变量。

  

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，LoginActivity.java：457中的代码是什么 

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

以下是我的模特课程：

  

PhysiotherapistResponse.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...........
  

PhysiotherapistInputData.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;

将遵循proguard规则添加到您的proguard文件中，它来自here 

   -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
