Example 11 with TrustedCertificateStore

use of com.android.org.conscrypt.TrustedCertificateStore in project platform_frameworks_base by android.

the class KeyChain method getCertificateChain.

/**
     * Returns the {@code X509Certificate} chain for the requested
     * alias, or null if there is no result.
     * <p>
     * <strong>Note:</strong> If a certificate chain was explicitly specified when the alias was
     * installed, this method will return that chain. If only the client certificate was specified
     * at the installation time, this method will try to build a certificate chain using all
     * available trust anchors (preinstalled and user-added).
     *
     * <p> This method may block while waiting for a connection to another process, and must never
     * be called from the main thread.
     * <p> As {@link Activity} and {@link Service} contexts are short-lived and can be destroyed
     * at any time from the main thread, it is safer to rely on a long-lived context such as one
     * returned from {@link Context#getApplicationContext()}.
     *
     * @param alias The alias of the desired certificate chain, typically
     * returned via {@link KeyChainAliasCallback#alias}.
     * @throws KeyChainException if the alias was valid but there was some problem accessing it.
     * @throws IllegalStateException if called from the main thread.
