Class Overview

Network security policy.

Network stacks/components should honor this policy to make it possible to centrally control the relevant aspects of network security behavior.

The policy currently consists of a single flag: whether cleartext network traffic is permitted. See isCleartextTrafficPermitted().

public boolean isCleartextTrafficPermitted ()

Added in API level 23

Returns whether cleartext network traffic (e.g. HTTP, FTP, WebSockets, XMPP, IMAP, SMTP -- without TLS or STARTTLS) is permitted for this process.

When cleartext network traffic is not permitted, the platform's components (e.g. HTTP and FTP stacks, DownloadManager, MediaPlayer) will refuse this process's requests to use cleartext traffic. Third-party libraries are strongly encouraged to honor this setting as well.

This flag is honored on a best effort basis because it's impossible to prevent all cleartext traffic from Android applications given the level of access provided to them. For example, there's no expectation that the Socket API will honor this flag because it cannot determine whether its traffic is in cleartext. However, most network traffic from applications is handled by higher-level network stacks/components which can honor this aspect of the policy.

NOTE: WebView does not honor this flag.
