앱만들기

• 이번에는 Basic Activity이용

• 이전에 버전업이되어서 최소 SDK를 26이상 해야 실행이됨

res/layout/frament.xml

before

    <TextView
        android:id="@+id/textview_first"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_first_fragment"
        app:layout_constraintBottom_toTopOf="@id/button_first"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

after

    <TextView
        android:id="@+id/tvVoice"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_first_fragment"
        android:textSize="20dp"
        app:layout_constraintBottom_toTopOf="@id/button_first"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

Sync, Asynce

• 동기
  • 함수가 올때 까지 기다리고
• 비동기
  • 함수 호출하자마자 다른 함수 호출되서 다른 화면이 실행하면서도 화면이 실행이되는것
  • 다른 행동을 할떄 다른것도 동작을 하게 하기 위해서 사용함

중요한것은 마이크 설정

• 가상 머신이라면 저렇게 해야 실행시 제대로 동작함

• 이렇게 일단 나옴

• 위와 같이 제대로 동작함을 알 수 있음
