7. UCAConstants.java

	// 진동 세기 저장

    public static final String SAVE_VIBRATION_PATTERN_CHECKBOX = "SAVE_VIBRATION_PATTERN_CHECKBOX";

2. 사용법

1. 퍼미션

<uses-permission android:name = "android.permission.VIBRATE"/>

2. 기본코드

    Vibrator vibrator = (Vibrator) context.getSystemService(context.VIBRATOR_SERVICE);
        AudioAttributes audioAttributes = new AudioAttributes.Builder()
                .setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
                .setUsage(AudioAttributes.USAGE_ALARM)
                .build();
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O && Build.VERSION_CODES.R >= Build.VERSION.SDK_INT) {
            vibrator.vibrate(VibrationEffect.createWaveform(timing, amplitudes,-1), audioAttributes);
        } else if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.O){
            vibrator.vibrate(timing,-1, audioAttributes);
        } else {
            vibrator.vibrate(VibrationEffect.createWaveform(timing, amplitudes, -1), audioAttributes);
        }

1. 반복횟수 -1은 1번, 0은 무한반복

2. timing

timing은 진동 패턴이다

long[] timing = new long[]{0,100,50,100,500,100}; //ms 타이밍

ms단위의 시간으로 진동의 길이와 끊어주는 시간을 만들 수 있다.

3. AudioAttributes

설정을 해주지 않으면 백그라운드에서 동작하지 않는다.

4. amplitudes

amplitudes는 진동세기이다

  int[] amplitudes = new int[]{0,125,0,125,0,125};

기본적으로 처음 진동세기는 지정해주어도 동작하지 않는다
0으로 시작하는 것이 좋다

5. 버전

버전별로 진동의 기능지원이 다르다.

Build.VERSION.SDK_INT >= Build.VERSION_CODES.O && Build.VERSION_CODES.R >= Build.VERSION.SDK_INT

Build.VERSION.SDK_INT <= Build.VERSION_CODES.O

"O버전 <= 지금버전 <= R버전"의 경우

VibrationEffect가 도입되었다.
기본 : VibrationEffect.createWaveform(timing, amplitudes,-1)
똑같이 timing는 패턴, amplitudes는 진동세기, -1는 반복횟수(1번)/0은 무한반복

"지금버전 <= O버전

vibrate를 가지고 바로 구현하면 된다

그외(R버전보다 클 때)

VibrationEffect 사용하면 된다
