Hi! On running this code, I get the following error: An abstract DAO method must be annotated with one and only one of the following annotations: Insert,Delete,Query,Update,RawQuery Please help me with this

CodePudding user response：

@JesúsBarrera from the comments is correct. check your imports. the annotation should be like this

@Delete

android studio will probably import this

import androidx.room.*

if not already present

CodePudding user response：

You entered wrong annotation

replace

@DELETE

@Delete
