如何解决Android Room：应用程序突然崩溃致命信号11SIGSEGV，代码1SEGV_MAPERR，错误地址0x0
我的问题是，我的应用突然崩溃了，我也不知道为什么。这种情况不定期发生，但我认为这与我的房间数据库有关。我尝试提供尽可能多的信息：
数据库
@Database(entities = [ProductCacheEntity::class],version = 1)
@TypeConverters(Converters::class)
abstract class ShoppingCartDatabase : RoomDatabase() {
abstract fun shopDao(): ShoppingCartDao
companion object {
const val DATABASE_NAME = "shop_db"
}
}
DAO
@Dao
interface ShoppingCartDao {
@Insert(onConflict = OnConflictStrategy.IGnorE)
suspend fun insert(productCacheEntity: ProductCacheEntity): Long
@Transaction
suspend fun upsert(productCacheEntity: ProductCacheEntity) {
val id = insert(productCacheEntity)
if (productExists(id)) increaseQuantityById(productCacheEntity.id)
}
@Query("UPDATE products SET quantity = quantity + 1 WHERE ID = :id")
suspend fun increaseQuantityById(id: Int)
@Query("UPDATE products SET quantity = quantity - 1 WHERE ID = :id")
suspend fun decreaseQuantityById(id: Int)
@Query("DELETE FROM products WHERE id = :id")
suspend fun deleteProductById(id: Int)
@Query("SELECT * FROM products")
