我正面临这个问题，在构建我的代码时，我遇到了这个异常。我已经尝试在 build.gradle 和 Manifest 文件中增加堆空间，但它们似乎都没有工作。我还更改了 gradle 属性，但效果不佳。

我认为我认为的问题是我正在使用数据绑定和空间，并且在为相同的文件生成文件时以某种方式出现了这个异常。

我有一种情况，我想使用 Room 持久性库将数据插入 Master (store_master) 和 Mapping (store_mapping) 表中的一对多关系。我的实现如下：

@Entity(tableName = "store_master")
class Store {

@PrimaryKey(autoGenerate = true)
public var store_id: Int = 0

@SerializedName("name")
lateinit var store_name: String
}

@Entity(tableName = "store_mapping", foreignKeys = arrayOf(
    ForeignKey(entity = Store::class,
            parentColumns = arrayOf("store_id"),
            childColumns = arrayOf("pic_id"),
            onDelete = CASCADE)))
class StorePicture(@field:PrimaryKey(autoGenerate = true)
          @ColumnInfo(name = "id") var id: Int,
          @SerializedName("pic_id") var pic_id: Int?,
          @SerializedName("image") var storage_picture: String?)

 class StoreWithPictures {
    @Embedded
    var store: Store? = null

    @Relation(parentColumn = "store_id",
        entityColumn = …
