SdkExtensions
public
class
SdkExtensions
extends Object
Methods for interacting with the extension SDK.
This class provides information about the extension SDK versions present
on this device. Use the getExtension method
to lookup the version of a given extension.
The extension version advances as the platform evolves and new APIs are added,
so is suitable to use for determining API availability at runtime.

Public methods
getAllExtensionVersions
public static Map<Integer, Integer> getAllExtensionVersions ()
Return all extension versions that exist on this device.
| Returns |
|---|
Map<Integer, Integer> |
a map from extension to extension version.
This value cannot be null. |
getExtensionVersion
public static int getExtensionVersion (int extension)
Return the version of the specified extensions.
This method is suitable to use in conditional statements to determine whether an API is
available and is safe to use. For example:
if (getExtensionVersion(VERSION_CODES.R) >= 3) {
// Safely use API available since R extensions version 3
}
