What do you want from Room when you create a DAO method and annotate it with @Update? Example: @Dao Interface MyDao { @Update Fun updateUsers(vararg users: User) }

If you added to your build.gradle file a room.schemaLocation : android {      defaultConfig {        javaCompileOptions {            annotationProcessorOptions {                arguments = ["room.schemaLocation": "$projectDir/schemas".toString()]            }        }    } } Then, you build your app or module. As a result you got a json file, with such path to it: app/schemas/your_app_package/db_package/DbClass/DB_VERSION.json What are the correct statements about this file? (Choose all that apply.)
