,模型是

import android.support.annotation.Keep;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
import org.parceler.Parcel;

@Parcel @Keep
public class LoginRequest {

static Gson gson = new GsonBuilder().setPrettyPrinting().create();

@SerializedName("username")
@Expose
String username;
@SerializedName("password")
@Expose
String password;

public LoginRequest(){

}

/**
 *
 * @return
 * The username
 */
public String getUsername() {
    return username;
}

/**
 *
 * @param username
 * The username
 */
public void setUsername(String username) {
    this.username = username;
}

/**
 *
 * @return
 * The password
 */
public String getPassword() {
    return password;
}

/**
 *
 * @param password
 * The password
 */
public void setPassword(String password) {
    this.password = password;
}

@Override
public String toString() {
    return gson.toJson(this);
}
}

如果我在gradle文件中有minifyEnabled为true,那么当我调用类的toString()方法时,我会得到一个像{ }这样的空字符串的请求。我尝试了所有可能的解决方案,但没有运气。

尝试将以下行添加到您的proguard规则中:

-keep class com.google.gson.** { *; }

答案 1 :(得分:0)

在我看来,这与GSON无关。如果您使用proguard,请记住proguard可以从类中删除某些字段,例如,如果应用程序不使用class的getter。因此,要解决此问题,只需将规则添加到您的proguard配置中,如:

# Classes that will be serialized/deserialized over Gson
 -keep class com.myclass.data.model.** { *; }

或者更轻松地将注释@Keep添加到您的字段,例如:

@SerializedName("username")
@Expose
@Keep
String username;
@SerializedName("password")
@Expose
@Keep
String password;
