EffectFactory


open class EffectFactory
kotlin.Any
   ↳ android.media.effect.EffectFactory

The EffectFactory class defines the list of available Effects, and provides functionality to inspect and instantiate them. Some effects may not be available on all platforms, so before creating a certain effect, the application should confirm that the effect is supported on this platform by calling isEffectSupported(java.lang.String).

Instantiate a new effect with the given effect name.

Return
Effect! A new Effect instance.
Exceptions
java.lang.IllegalArgumentException if the effect with the specified name is not supported or not known.

isEffectSupported

Added in API level 14
open static fun isEffectSupported(effectName: String!): Boolean

Check if an effect is supported on this platform.

Some effects may only be available on certain platforms. Use this method before instantiating an effect to make sure it is supported.

Parameters
effectName String!: The name of the effect.
Return
Boolean true, if the effect is supported on this platform.
Exceptions
java.lang.IllegalArgumentException if the effect name is not known.
