public final boolean secure

Whether the surface is secure.

synchronized public static boolean isSecureSupported(Context context)

Returns whether the device supports secure placeholder surfaces.

Parameters
`Context context`	Any `Context`.

Returns
`boolean`	Whether the device supports secure placeholder surfaces.

public static PlaceholderSurface newInstanceV17(Context context, boolean secure)

Returns a newly created placeholder surface. The surface must be released by calling release when it's no longer required.

Must only be called if SDK_INT is 17 or higher.

Parameters
`Context context`	Any `Context`.
`boolean secure`	Whether a secure surface is required. Must only be requested if `isSecureSupported` returns `true`.

Throws
`java.lang.IllegalStateException`	If a secure surface is requested on a device for which `isSecureSupported` returns `false`.
