Vibration effect support: unknown

The hardware doesn't report its supported effects, so we can't determine whether the effect is supported or not.

Constants

VIBRATION_EFFECT_SUPPORT_NO

Added in API level 30
public static final int VIBRATION_EFFECT_SUPPORT_NO

This effect is not natively supported by the underlying hardware, although the system may still play a fallback vibration.

Constant Value: 2 (0x00000002)

VIBRATION_EFFECT_SUPPORT_UNKNOWN

Public methods

areAllEffectsSupported

Added in API level 30
public final int areAllEffectsSupported (int... effectIds)

Query whether the vibrator supports all the given effects. If no argument is provided this method will always return VIBRATION_EFFECT_SUPPORT_YES.

If an effect is not supported, the system may still automatically fall back to a simpler vibration instead, which is not optimised for the specific device, however vibration isn't guaranteed in this case.

If the result is VIBRATION_EFFECT_SUPPORT_YES, all effects in the query are supported by the hardware.

If the result is VIBRATION_EFFECT_SUPPORT_NO, at least one of the effects in the query is not supported, and using them may fall back to an un-optimized vibration or no vibration.

If the result is VIBRATION_EFFECT_SUPPORT_UNKNOWN, the system doesn't know whether all the effects are supported. It may support any or all of the queried effects, but there's no way to programmatically know whether a vibrate(VibrationEffect) call will successfully cause a vibration. It's guaranteed, however, that none of the queried effects are definitively unsupported by the hardware.

Use areEffectsSupported(int) to get individual results for each effect.

Parameters
effectIds int: Which effects to query for. This value cannot be null. Value is VibrationEffect.EFFECT_TICK, VibrationEffect.EFFECT_CLICK, VibrationEffect.EFFECT_HEAVY_CLICK, or VibrationEffect.EFFECT_DOUBLE_CLICK

Returns
int Whether all specified effects are natively supported by the device. Empty query defaults to VIBRATION_EFFECT_SUPPORT_YES. Value is VIBRATION_EFFECT_SUPPORT_UNKNOWN, VIBRATION_EFFECT_SUPPORT_YES, or VIBRATION_EFFECT_SUPPORT_NO

areAllPrimitivesSupported

Added in API level 30
public final boolean areAllPrimitivesSupported (int... primitiveIds)

Query whether the vibrator supports all of the given primitives. If no argument is provided this method will always return true.

If a primitive is not supported by the device, then no vibration will occur if it is played.

Use arePrimitivesSupported(int) to get individual results for each primitive.

Parameters
primitiveIds int: Which primitives to query for. This value cannot be null. Value is VibrationEffect.Composition.PRIMITIVE_CLICK, VibrationEffect.Composition.PRIMITIVE_THUD, VibrationEffect.Composition.PRIMITIVE_SPIN, VibrationEffect.Composition.PRIMITIVE_QUICK_RISE, VibrationEffect.Composition.PRIMITIVE_SLOW_RISE, VibrationEffect.Composition.PRIMITIVE_QUICK_FALL, VibrationEffect.Composition.PRIMITIVE_TICK, or VibrationEffect.Composition.PRIMITIVE_LOW_TICK

Returns
boolean Whether all specified primitives are supported. Empty query defaults to true.

areEffectsSupported

Added in API level 30
public int[] areEffectsSupported (int... effectIds)

Query whether the vibrator natively supports the given effects.

If an effect is not supported, the system may still automatically fall back to playing a simpler vibration instead, which is not optimised for the specific device. This includes the unknown case, which can't be determined in advance, that will dynamically attempt to fall back if the optimised effect fails to play.

The returned array will be the same length as the query array and the value at a given index will contain VIBRATION_EFFECT_SUPPORT_YES if the effect at that same index in the querying array is supported, VIBRATION_EFFECT_SUPPORT_NO if it isn't supported, or VIBRATION_EFFECT_SUPPORT_UNKNOWN if the system can't determine whether it's supported or not, as some hardware doesn't report its effect capabilities.

Use areAllEffectsSupported(int) to get a single combined result, or for convenience when querying exactly one effect.

Parameters
effectIds int: Which effects to query for. This value cannot be null. Value is VibrationEffect.EFFECT_TICK, VibrationEffect.EFFECT_CLICK, VibrationEffect.EFFECT_HEAVY_CLICK, or VibrationEffect.EFFECT_DOUBLE_CLICK

Returns
int[] An array containing the systems current knowledge about whether the given effects are natively supported by the device, or not. This value cannot be null. Value is VIBRATION_EFFECT_SUPPORT_UNKNOWN, VIBRATION_EFFECT_SUPPORT_YES, or VIBRATION_EFFECT_SUPPORT_NO

arePrimitivesSupported

Added in API level 30
public boolean[] arePrimitivesSupported (int... primitiveIds)

Query whether the vibrator supports the given primitives. The returned array will be the same length as the query array and the value at a given index will contain whether the effect at that same index in the querying array is supported or not.

If a primitive is not supported by the device, then no vibration will occur if it is played.

Use areAllPrimitivesSupported(int) to get a single combined result, or for convenience when querying exactly one primitive.

Parameters
primitiveIds int: Which primitives to query for. This value cannot be null. Value is VibrationEffect.Composition.PRIMITIVE_CLICK, VibrationEffect.Composition.PRIMITIVE_THUD, VibrationEffect.Composition.PRIMITIVE_SPIN, VibrationEffect.Composition.PRIMITIVE_QUICK_RISE, VibrationEffect.Composition.PRIMITIVE_SLOW_RISE, VibrationEffect.Composition.PRIMITIVE_QUICK_FALL, VibrationEffect.Composition.PRIMITIVE_TICK, or VibrationEffect.Composition.PRIMITIVE_LOW_TICK

Returns
boolean[] Whether the primitives are supported. This value cannot be null.

Requires Manifest.permission.VIBRATE

getId

Added in API level 31
public int getId ()

Return the ID of this vibrator.

Returns

getPrimitiveDurations

Added in API level 31
public int[] getPrimitiveDurations (int... primitiveIds)

Query the estimated durations of the given primitives.

The returned array will be the same length as the query array and the value at a given index will contain the duration in milliseconds of the effect at the same index in the querying array.

The duration will be positive for primitives that are supported and zero for the unsupported ones, in correspondence with arePrimitivesSupported(int).

Parameters
primitiveIds int: Which primitives to query for. This value cannot be null. Value is VibrationEffect.Composition.PRIMITIVE_CLICK, VibrationEffect.Composition.PRIMITIVE_THUD, VibrationEffect.Composition.PRIMITIVE_SPIN, VibrationEffect.Composition.PRIMITIVE_QUICK_RISE, VibrationEffect.Composition.PRIMITIVE_SLOW_RISE, VibrationEffect.Composition.PRIMITIVE_QUICK_FALL, VibrationEffect.Composition.PRIMITIVE_TICK, or VibrationEffect.Composition.PRIMITIVE_LOW_TICK

Returns
