Provides interfaces for third party app developers to get capabilities info of extension functions.

Summary

Nested classes
	EffectMode The effect mode options applied on the bound use cases
	ExtensionsAvailability

Public methods
static ListenableFuture<ExtensionsManager.ExtensionsAvailability!>	init(@NonNull context: Context) Initialize the extensions asynchronously.
static Boolean	isExtensionAvailable(@NonNull effectMode: ExtensionsManager.EffectMode, lensFacing: Int) Indicates whether the camera device with the lensFacing can support the specific extension function.
static Boolean	isExtensionAvailable(@NonNull klass: Class<*>, @NonNull effectMode: ExtensionsManager.EffectMode, lensFacing: Int) Indicates whether the camera device with the lensFacing can support the specific extension function for specific use case.
static Unit	setExtensionsErrorListener(@Nullable listener: ExtensionsErrorListener?) Sets an ExtensionsErrorListener which will get called any time an extensions error is encountered.

Public methods

init

@NonNull static fun init(@NonNull context: Context): ListenableFuture<ExtensionsManager.ExtensionsAvailability!>

Initialize the extensions asynchronously.

This should be the first call to the extensions module. An application must wait until the ListenableFuture completes before making any other calls to the extensions module.

isExtensionAvailable

static fun isExtensionAvailable(
    @NonNull effectMode: ExtensionsManager.EffectMode, 
    lensFacing: Int
): Boolean

Indicates whether the camera device with the lensFacing can support the specific extension function.

Parameters
effectMode	ExtensionsManager.EffectMode: The extension function to be checked.
lensFacing	Int: The lensFacing of the camera device to be checked.

Return
Boolean	True if the specific extension function is supported for the camera device.

isExtensionAvailable

static fun isExtensionAvailable(
    @NonNull klass: Class<*>, 
    @NonNull effectMode: ExtensionsManager.EffectMode, 
    lensFacing: Int
): Boolean

Indicates whether the camera device with the lensFacing can support the specific extension function for specific use case.

Parameters
klass	Class<*>: The ImageCapture or Preview class to be checked.
effectMode	ExtensionsManager.EffectMode: The extension function to be checked.
lensFacing	Int: The lensFacing of the camera device to be checked.

Return
Boolean	True if the specific extension function is supported for the camera device.

setExtensionsErrorListener

static fun setExtensionsErrorListener(@Nullable listener: ExtensionsErrorListener?): Unit

Sets an ExtensionsErrorListener which will get called any time an extensions error is encountered.

Parameters
listener	ExtensionsErrorListener?: The ExtensionsErrorListener listener that will be run.
