annotationProcessor("com.github.bumptech.glide:compiler:4.14.2")</code></pre>&nbsp;AndroidManifest.xml<pre><code><uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/></code></pre>&nbsp;&nbsp;

Room db kotlin 관련질문

일부오류는 사라졌으나 아래부분에서 오류가 발생합니다addButton.setOnClickListener( db.todoDao().insert(Todo(todoEdit.text.toString())) resultText.text = db.todoDao().getAll().toString() )&nbsp;<img src="https://cdn.inflearn.com/public/files/posts/22c38aa6-9da1-475f-9872-7415ba3afeba/q2.png" alt="q2.png" title="q2.png">
