Now, you can use the Knox APIs to manage certificates in TIMA CCM.

Create CCM Profile

This method initializes a CCMProfile object, sets its accessControlMethod to default and asks the user if they want to whitelist all the packages in the container.

private void createCCMProfile() {
        // Initialize a CCMProfile object
        mCCMProfileObj = new CCMProfile();
        // Set its accessControlMethod to the default method
        mCCMProfileObj.accessControlMethod = CCMProfile.AccessControlMethod.LOCK_STATE;

        // Proceed to ask the user if they want to whitelist all packages
        whitelistAllPackages();
    }	

Whitelist all packages

This method asks the user if they want to whitelist all the packages in the container. Whitelisting allows them access to the token. If they do, the app skips asking the user to whitelist specific package names and set the CCM profile. If they don't, it asks the user to whitelist specific package names before setting the CCM profile.

private void whitelistAllPackages() {
        // Create a dialog box to show to the user
        new AlertDialog.Builder(this)
                // Set the dialog box's title

                // Set the dialog box's message
                .setMessage(getString(R.string.whitelist_all_packages_message))

                        // Whitelist all the packages, then set the CCM profile
                        mCCMProfileObj.whiteListAllPackages = true;
                        setCCMProfile();
                    }

                whitelistPackagesToAccessToken();
            }
        }).show();
    }

Whitelist specific packages

This method prompts the user to select certain packages in the container to be whitelisted, allowing them to access the token.

        // Convert the list of installed packages to an array
        final String[] installedPackagesArr = installedPackages.toArray(

Add package to the exempt list

This method adds the given package name to the exempt list. This is required in case an app (running in background) needs access to certificates when the device or container is locked, or the user is not expected to enter a password. An example of a package that requires exemption is a third-party VPN application that needs to access certificates without user interaction.

private void addPackageToExemptList (String packageName) {
        // Instantiate the EnterpriseKnoxManager class
        EnterpriseKnoxManager enterpriseKnoxManager = EnterpriseKnoxManager.getInstance(this);
        // Get the ClientCertificateManager where the addPackageToExemptList method lives
        ClientCertificateManager clientCertificateManager = enterpriseKnoxManager.
                getClientCertificateManagerPolicy();

        try {
            // attempt to add package name to exempt list
            boolean result = clientCertificateManager.addPackageToExemptList(packageName);
            if (result) {
                mUtils.log(getString(R.string.package_name_added_exempt_list_success));
            } else {
                mUtils.log(getString(R.string.package_name_added_exempt_list_failed));
            }
        } catch (SecurityException e) {
            mUtils.processException(e, TAG);
        }
    }

Remove package from the exempt list

This method removes the given package name from the exempt list.

private void removePackageFromExemptList (String packageName) {
        // Instantiate the EnterpriseKnoxManager class
        EnterpriseKnoxManager enterpriseKnoxManager = EnterpriseKnoxManager.getInstance(this);
        // Get the ClientCertificateManager where the removePackageFromExemptList method lives
        ClientCertificateManager clientCertificateManager = enterpriseKnoxManager.
                getClientCertificateManagerPolicy();

        try {
            // attempt to add package name to exempt list
            boolean result = clientCertificateManager.removePackageFromExemptList(packageName);
            if (result) {
                mUtils.log(getString(R.string.package_name_remove_exempt_list_success));
            } else {
                mUtils.log(getString(R.string.package_name_remove_exempt_list_failed));
            }
        } catch (SecurityException e) {
            mUtils.processException(e, TAG);
        }
    }

Check CCM Policy for a package

This method checks if a CCM policy is enabled for a package.

private void checkCCMEnabledForPackage (String packageName) {
        // Instantiate the EnterpriseKnoxManager class
        EnterpriseKnoxManager enterpriseKnoxManager = EnterpriseKnoxManager.getInstance(this);
        // Get the ClientCertificateManager where the isCCMPolicyEnabledForPackage method lives
        ClientCertificateManager clientCertificateManager = enterpriseKnoxManager.
                getClientCertificateManagerPolicy();

        try {
            // attempt to add package name to exempt list
            boolean result = clientCertificateManager.isCCMPolicyEnabledForPackage(packageName);
            if (result) {
                mUtils.log(getString(R.string.ccm_policy_enabled_for_package, packageName));
            } else {
                mUtils.log(getString(R.string.ccm_policy_not_enabled_for_package, packageName));
            }
        } catch (SecurityException e) {
            mUtils.processException(e, TAG);
        }
    }

Toggle TIMA Keystore state

This method enables/disables the TIMA Keystore state.

private void toggleTimaKeystoreState () {
        // Instantiate the EnterpriseKnoxManager class
        EnterpriseKnoxManager enterpriseKnoxManager = EnterpriseKnoxManager.getInstance(this);
        // Get the TimaKeystore object where the enableTimaKeystore method lives
        TimaKeystore timaKeystore = enterpriseKnoxManager.getTimaKeystorePolicy();

        try {
            // Check current status of the TimaKeystore
            boolean isTimaKeystoreEnabled = timaKeystore.isTimaKeystoreEnabled();
            mUtils.log("Attempting to toggle. Is enabled? " + isTimaKeystoreEnabled);

            // Enable/disable the Tima Keystore
            boolean result = timaKeystore.enableTimaKeystore(!isTimaKeystoreEnabled);

            if (result) {
                mUtils.log(getString(R.string.toggled_tima_keystore, !isTimaKeystoreEnabled));
            } else {
                mUtils.log(getString(R.string.failed_to_toggle_tima_keystore));
            }
        } catch (SecurityException e) {
            mUtils.processException(e, TAG);
        }
    }

Display TIMA Keystore status

This method displays the TIMA Keystore status as "enabled" or "disabled".

private void isTimaKeystoreEnabled () {
        // Instantiate the EnterpriseKnoxManager class
        EnterpriseKnoxManager enterpriseKnoxManager = EnterpriseKnoxManager.getInstance(this);
        // Get the TimaKeystore object where the enableTimaKeystore method lives
        TimaKeystore timaKeystore = enterpriseKnoxManager.getTimaKeystorePolicy();

        try {
            // Check current status of the TimaKeystore
            boolean isTimaKeystoreEnabled = timaKeystore.isTimaKeystoreEnabled();
            mUtils.log(getString(R.string.tima_keystore_status, isTimaKeystoreEnabled));
        } catch (SecurityException e) {

        }
    }
