DLP sample application

DLP sample application demonstrates usage of <Text /> and <TextInput /> UI components together with DLP policy option on UEM. If DLP is on, it will not be possible to do cut-copy-paste operations over data from "Dynamics" to "non-Dynamics" application and vice-versa.

How to prepare the app

Open the sample app directory in Terminal window: $ cd <path>/SampleApplications/DLP

Install dependencies: $ yarn

NOTE: DLP sample is based on 0.70.0 version of React Native. There is a possibility to upgrade to 0.70.x, 0.71.x, 0.72.x versions (0.70.1 - 0.70.10, 0.71.0 - 0.71.13, 0.72.0 - 0.72.4) by running one of following commands: $ npx react-native upgrade 0.70.x for example: $ npx react-native upgrade 0.70.10 or $ npx react-native upgrade 0.71.13 or $ npx react-native upgrade 0.72.4

Generate ios and android directories: $ npx react-native eject

There is a known issue with loading Metro server on 0.72.0 and 0.72.1 versions when the error message is displayed during app load in Metro server: "Cannot read properties of undefined (reading 'addHelper')". The issue can be fixed by adding the following devDependency to the project: $ yarn add @babel/traverse@7.22.8 --dev

Dynamics modules

Prerequisites

There are some dependencies that need to be installed before using BlackBerry-Dynamics-for-React-Native-Base module. More information can be found here.

How to integrate Dynamics into application

$ yarn add <path>/modules/BlackBerry-Dynamics-for-React-Native-Base

Integrates Dynamics based on your current identifiers - iOS Bundle ID and Android Package Name.

$ yarn set-bundle-id (Optional step, but required for sample applications)

Allows to update an identifier (required) and name (optional) for your application. This identifier is your iOS Bundle ID or Android Package Name. It will also be used as the Entitlement ID for entitling and activating your application with the BlackBerry UEM management console.

How to secure <Text /> UI component

$ yarn add <path>/ui-components/BlackBerry-Dynamics-for-React-Native-Text

NOTE: BlackBerry-Dynamics-for-React-Native-Text should be the last package added to your project dependencies. Adding modules or UI components after BlackBerry-Dynamics-for-React-Native-Text can override some important configurations that may cause following exception during application launch: "Text strings must be rendered within a <Text> component". If this is the case please run yarn set-text-config command to put needed configurations back. This action should be repeated when add/remove other packages.

How to secure <TextInput /> UI component

$ yarn add <path>/ui-components/BlackBerry-Dynamics-for-React-Native-TextInput
iOS

Different ruby versions might be install on the machine. Especially it is related to React Native v0.70.x projects. Depending on your Mac configuration following error can occur when running pod install command:

Traceback (most recent call last):

More details can be found here.

$ bundle install - needed on some 0.70.x versions to fix the issue above
$ cd ios
$ pod install
$ cd ..

How to secure react-native-elements

react-native-elements is cross-platform React Native UI toolkit. There are many ready-to-use UI components that can extend React Native application.

react-native-elements are implemented using original Text and TextInput components which means DLP is not supported by default. In order to enable DLP within react-native-elements it is required to update imports in <app_name>/node_modules/react-native-elements/src/* according to following principle:

import {Text, TextInput} from 'react-native';

should be replaced with

import Text from 'BlackBerry-Dynamics-for-React-Native-Text';
import TextInput from 'BlackBerry-Dynamics-for-React-Native-TextInput';
