Simulate API 29 Vibrations in 26 and below

Question

I want to simulate API 29 vibration effects:

EFFECT_CLICK
EFFECT_DOUBLE_CLICK
EFFECT_HEAVY_CLICK
EFFECT_TICK

in version 26 and lower as well. Does anybody know how these translate?

Answer 1

Here is what I did. I am only covering two types of vibrations which will have to do. A longer single one and two short ones, which may translate to CLICK and DOUBLE_CLICK:

private void vibrate(int vibrationMessageId) {

    long[] doubleClickPattern = {0, 75, 75, 75};

    if (Build.VERSION.SDK_INT >= 26) {
        Log.d(TAG, "vibrate: SDK 26+ " + Build.VERSION.SDK_INT);

        switch (vibrationMessageId) {
            case Constants.VIBRATION_HEAVY_CLICK:
                ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createOneShot(200, VibrationEffect.DEFAULT_AMPLITUDE));
                break;
            case Constants.VIBRATION_DOUBLE_CLICK:
                ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createWaveform(doubleClickPattern,-1));
                break;
        }


    } else {
        Log.d(TAG, "vibrate: SDK <26 " + Build.VERSION.SDK_INT);

        switch (vibrationMessageId) {
            case Constants.VIBRATION_HEAVY_CLICK:
                ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(200);
                break;
            case Constants.VIBRATION_DOUBLE_CLICK:

                ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(doubleClickPattern,-1);
                break;
        }
    }
}
