我的应用程序在混淆之前工作正常,但是当我启用proguard时,我收到以下错误:

我的proguard配置包含以下内容:

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

那么Parcelable应该保持正确吗?它投掷的无效长度实际上是我请求的另一部分,所以它正在读取错误的数字。我是否还必须保留我的HttpResponse课程?还有什么呢?

2 个答案:

答案 0 :(得分:3)

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

不保留您班级的所有内容,只保留班级名称和CREATOR方法。

尝试在Parcelable类中保留字段,添加如下内容:

-keepclassmembers class * implements android.os.Parcelable {
 public <fields>;
}

答案 1 :(得分:-1)

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

它只保留班级名称和创作者。

您应该将其更改为

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

默认的android规则包含上述指令,如果保留默认生成的gradle定义,它也将应用于您的项目:

proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
