我正在使用retrofit，gson和realm，我真的不知道导致此错误的原因，但它只发生在版本apk中{{ 1}}是minifyEnabled，所以我猜它已经发布了，但我不确切知道这个问题是什么。
这是我的错误：

@SerializedName("posts")
private List<Post> posts;
public List<Post> getPosts() {
return posts;
}
public void setPosts(List<Post> posts) {
this.posts = posts;
}
}
：
Post.java我的 @RealmClass

private int commentCount;
@SerializedName("likesCount")
private int likesCount;

private int shareCount;
@SerializedName("picUrl")
private String picUrl;
@SerializedName("voiceUrl")
private String voiceUrl;
@SerializedName("creationDate")
@JsonAdapter(TimestampDeserializer.class)
private Date creationDate;
@SerializedName("comments")
private RealmList<Comment> comments;
public Post() {
}
public Post(String picUrl, String caption, int voiceDuration) {
this.picUrl = picUrl;
this.caption = caption;
this.voiceDuration = voiceDuration;
}
public String getCreatedFrom()
{
return Utility.getCreatedFromString(creationDate);
}
public int getPostId() {
return postId;
}
public String getPicUrl() {
return picUrl;
}
public void setPicUrl(String picUrl) {
this.picUrl = picUrl;
}
public int getVoiceDuration() {
return voiceDuration;
}
public void setVoiceDuration(int voiceDuration) {

}

}
public UserDto getUserDto() {
return userDto;
}
public void setUserDto(UserDto userDto) {
this.userDto = userDto;
}
}
课程：
UserDto这是我的改装配置：
@RealmClass
public class UserDto implements RealmModel {
@PrimaryKey
@SerializedName("userId")
private int userId;
@SerializedName("fName")
private String fName;
@SerializedName("lName")
private String lName;
@SerializedName("pictureLocation")
private String pictureLocation;
public UserDto() {}
public UserDto(int userId, String fname, String lname, String pictureLocation) {
setUserId(userId);
setfName(fname);
setlName(lname);
setPictureLocation(pictureLocation);
}
public int getUserId() {
return userId;
}
public void setUserId(int userId) {
this.userId = userId;
}
public String getFName() {
return fName;
}
public String getLName() {
return lName;
}
public String getPictureLocation() {
return pictureLocation;
}
public void setfName(String fName) {
this.fName = fName;
}
public void setlName(String lName) {
this.lName = lName;
}
public void setPictureLocation(String pictureLocation) {
this.pictureLocation = pictureLocation;
}
}
最后我的Proguard文件：
private Retrofit.Builder createRetrofitBuilder() {
HttpLoggingInterceptor httpLoggingInterceptor = new HttpLoggingInterceptor();
if(BuildConfig.BUILD_TYPE.equals("release")) {
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.NONE);
} else {
httpLoggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
}
OkHttpClient client = new OkHttpClient.Builder()
.addInterceptor(httpLoggingInterceptor)
.build();
GsonBuilder gsonBuilder = new GsonBuilder();
return new Retrofit.Builder()
.baseUrl(BASE_URL)
.client(client)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create(gsonBuilder.create()));
}
答案 0 :(得分：7)
似乎Retrofit在方法getPosts()中失败，很可能是由于找不到Post类。您似乎并未包含Realm特定的ProGuard规则：
-keep class io.realm.annotations.RealmModule
-keep @io.realm.annotations.RealmModule class *
-keep class io.realm.internal.Keep
-keep @io.realm.internal.Keep class *
-dontwarn javax.**
-dontwarn io.realm.**
强制所有使用@RealmModule注释的类在混淆和修剪期间保留。将这些规则添加到ProGuard文件应该可以解决问题。
