Sugar ORM生成单个表的速度非常慢(没有类加载器的燕麦文件。已弃用的DexFile API?)

我有一个简单的实体,叫做 Dog (狗),它位于包“ com.plat.model”

public class Dog extends SugarRecord<Dog> implements Parcelable {

String name;

public Dog() {}

public Dog(Parcel in) {
    this.id = in.readLong();
    this.name = in.readString();

}

@Override
public void writeToParcel(Parcel dest, int flags) {

    if (this.id != null) {
        dest.writeLong(this.id);
    } else {
        dest.writeLong(-1);
    }
    dest.writeString(this.name);

}

public static final Creator CREATOR = new Creator() {
    public Dog createFromParcel(Parcel in) {
        return new Dog(in);
    }

    public Dog[] newArray(int size) {
        return new Dog[size];
    }
};

@Override
public int describeContents() {
    return 0;
}
}

我在清单文件和应用程序的类中启动了Sugar ORM:

<application

    android:name="com.plat.app.MyApp"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

    <meta-data
        android:name="DATABASE"
        android:value="platinum_dogs.db" />
    <meta-data
        android:name="VERSION"
        android:value="11" />
    <meta-data
        android:name="QUERY_LOG"
        android:value="false" />
    <meta-data
        android:name="DOMAIN_PACKAGE_NAME"
        android:value="com.plat.model" />

//...

应用程序类别:

public class MyApp extends SugarApp {

@Override
public void onCreate() {
    super.onCreate();

}
}

当我启动该应用程序时,糖罐的负载就像永远一样。我有一个只有名称属性的表,并且它的生成时间超过30秒。与表创建和表升级相同。

这是什么'W / zygote64:在没有类加载器的情况下打开燕麦文件。您正在使用不推荐使用的DexFile API吗?警告?

我使用糖球已有多年了,但是我从未见过。

该应用程序的 targetSdkVersion compileSdkVersion 28

可能是什么问题?

谢谢。
