아래처럼 수정하니 Glide 부분에 에러가 사라지는군요 왜 그럴까요 ??? build.gradle.kts implementation("com.github.bumptech.glide:glide:4.14.2") annotationProcessor("com.github.bumptech.glide:compiler:4.14.2") AndroidManifest.xml
질문&답변
아차 제실수이군요 AndroidManifest.xml 부분을 입력하지 않았습니다 죄송합니다

해당코드를 viewModel = ViewModelProvider(this)[MainViewModel:: class. java ] 로 변경하니 오류가 사라지네요 캄사합니다

질문&답변
일부오류는 사라졌으나 아래부분에서 오류가 발생합니다 addButton.setOnClickListener( db.todoDao().insert(Todo(todoEdit. text .toString())) resultText.text = db.todoDao().getAll().toString() )
