VibrationEffect

DEFAULT_AMPLITUDE

static val DEFAULT_AMPLITUDE: Int

The default vibration strength of the device.

Value: -1

EFFECT_CLICK

static val EFFECT_CLICK: Int

A click effect. Use this effect as a baseline, as it's the most common type of click effect.

Value: 0

EFFECT_DOUBLE_CLICK

static val EFFECT_DOUBLE_CLICK: Int

A double click effect.

Value: 1

EFFECT_HEAVY_CLICK

static val EFFECT_HEAVY_CLICK: Int

A heavy click effect. This effect is stronger than EFFECT_CLICK.

Value: 5

EFFECT_TICK

static val EFFECT_TICK: Int

A tick effect. This effect is less strong compared to EFFECT_CLICK.

Value: 2

createOneShot

open static fun createOneShot(
    milliseconds: Long, 
    amplitude: Int
): VibrationEffect!

Create a one shot vibration.

One shot vibrations will vibrate constantly for the specified period of time at the specified amplitude, and then stop.

createPredefined

open static fun createPredefined(effectId: Int): VibrationEffect

Create a predefined vibration effect.

Predefined effects are a set of common vibration effects that should be identical, regardless of the app they come from, in order to provide a cohesive experience for users across the entire device. They also may be custom tailored to the device hardware in order to provide a better experience than you could otherwise build using the generic building blocks.

This will fallback to a generic pattern if one exists and there does not exist a hardware-specific implementation of the effect.

createWaveform

open static fun createWaveform(
    timings: LongArray!, 
    repeat: Int
): VibrationEffect!

Create a waveform vibration, using only off/on transitions at the provided time intervals, and potentially repeating.

In effect, the timings array represents the number of milliseconds before turning the vibrator on, followed by the number of milliseconds to keep the vibrator on, then the number of milliseconds turned off, and so on. Consequently, the first timing value will often be 0, so that the effect will start vibrating immediately.

This method is equivalent to calling createWaveform(long[],int[],int) with corresponding amplitude values alternating between 0 and DEFAULT_AMPLITUDE, beginning with 0.

To cause the pattern to repeat, pass the index into the timings array at which to start the repetition, or -1 to disable repeating. Repeating effects will be played indefinitely and should be cancelled via Vibrator#cancel().

createWaveform

open static fun createWaveform(
    timings: LongArray!, 
    amplitudes: IntArray!, 
    repeat: Int
): VibrationEffect!

Create a waveform vibration.

Waveform vibrations are a potentially repeating series of timing and amplitude pairs, provided in separate arrays. For each pair, the value in the amplitude array determines the strength of the vibration and the value in the timing array determines how long it vibrates for, in milliseconds.

To cause the pattern to repeat, pass the index into the timings array at which to start the repetition, or -1 to disable repeating. Repeating effects will be played indefinitely and should be cancelled via Vibrator#cancel().
