This guide will walk you through working with the Apache Cordova BlackBerry repository. It will describe the repository’s structure and the purpose of each file and directory. In addition, it will describe how to deploy an application using the command line tools.
If you haven’t deployed to a BlackBerry device before, you should first read the BlackBerry Getting Started Guide in order to have everything ready to go.
Note: The devices this guide will be able to deploy to include BlackBerry 5-7, PlayBook, and the new BlackBerry 10.
However, on the BlackBerry platform, there exists a framework called WebWorks. Instead of Cordova setting up the infrastructure for the chromeless browser and packaging, WebWorks handles this.
Furthermore, WebWorks exposes a lot of the native BlackBerry APIs through JS calls. A way to think about WebWorks is to consider it as Cordova, but created by BlackBerry and for the BlackBerry platform.
It depends. Developers who are only interested in deploying to the BlackBerry platform might just want to use WebWorks. However, if a developer wants to deploy to multiple platforms, then using Cordova makes a lot of sense. This is because the JS APIs that Cordova offers are unified across the platforms. Therefore, the changes required when porting your app to other mobile platforms can be reduced by a fair amount.
Our first step is to clone the repo from the Apache hosted Git repository.
Here’s what the structure of the repo looks like:
Now open up your terminal and cd into the repo’s directory. Using the Cordova scripts will allow you to build a new project. For example,
./bin/cordova/create [path_of_project] will create a new basic project at the path specified, otherwise it will create a new example project from where you call it.
To note, if you create a new example project and run the script again, it will throw an error telling you that the existing example project already exists.
This is what the output of the
bin/create scripts looks like:
├── example | # | # ant file for building BlackBerry OS 5-7 | # | ├── blackberry.xml | # | # The top level ant file for building BlackBerry projects (ie, calls the | # sub-ant files for the specific platform you're building on) | # | ├── build.xml | # | # Contains the Cordova scripts for running and building BlackBerry projects. | # These are aligned with the other Cordova platforms and rely on the ant files | # to build a BlackBerry project. | # | ├── cordova | │ ├── build | │ └── run | # | # Contains an ant library and the native code for BlackBerry (gets copied in from | # the root) | # | ├── lib | │ ├── ant-contrib | │ └── cordova.2.3.0 | # | # ant file for building Playbook | # | ├── playbook.xml | # | # Config file for specifying where your BlackBerry Webworks SDK files are, | # signing passwords, device ips, etc | # | ├── project.properties | # | # ant file for building BlackBerry 10 | # | ├── qnx.xml | # | # the app folder | # | └── www
Let’s cd into the
www/ folder. This folder should contain all of your app’s assets. When you build an app, it’ll launch with the “Hello World” app so there’s a fair amount of stuff in there that you actually don’t need to worry about. I’ll just make points on the things you should worry about:
├── www | ├── LICENSE | ├── NOTICE | ├── README.md | ├── VERSION | # | # This is where all of the configuration settings go for your BlackBerry app. | # For example, the name of the app, version, permissions, and whitelisting goes. | # See this page for a complete listing of what elements you can use: | # https://developer.blackberry.com/html5/documentation/config_doc_elements.html | # | ├── config.xml | # | # The cordova JS file | # | ├── cordova-2.3.0.js | ├── css | │ └── index.css | # | # These ext folders are copied in from one level above | # | ├── ext | │ └── cordova.2.3.0.jar | ├── ext-air | │ └── Cordova_Network | ├── ext-qnx | │ └── readme.md | ├── img | │ └── logo.png | # | # This is the initial start page of your app | # | ├── index.html | ├── js | │ └── index.js | ├── json2.js | ├── plugins.xml | ├── res | │ ├── icon | │ ├── resourceBundles | │ └── screen | ├── spec | └── spec.html
If this is your first time deploying a BlackBerry app, I highly recommend reading the BlackBerry Getting Started Guides After following that guide, you should have all the necessary pieces to start developing your app.
The basic flow I usually go through in deploying an app is to cd into the BlackBerry repo and create a new project using
./bin/create. Then I’ll cd into the project folder I just made and update the project properties so it points to the right SDK and has the correct signing key passwords. Typically I like to copy & paste a saved version of the
project.properties with all of the correct information, but you can actually deploy a new project with the correct
project.properties file every time if you just update that in the
repo_root_folder/bin/templates/project/project.properties. Of course, the problem with this is that if you decide to pull from the repo in the future, Git will say you unstaged commits or may accidentally commit this file to a Git repo with your valuable signing passwords.
In any case, after updating the
project.properties file, cd into the
www/ folder and change the
config.xml. In that file, update your app name otherwise it’ll default to
cordovaExample. You may also wish to update your whitelisting URLs. You may notice that it says this within the
<!-- Expose access to all URIs, including the file and http protocols --> <access subdomains="true" uri="*" />
I find that in most cases, you’ll actually need to specify the specific url to get that whitelisting to work. So don’t rely on the wildcard and actually put in the urls your app will be accessing.
Once that’s done, connect your BlackBerry device to your computer or turn on your simulator. It’s important to note that you need to turn on development mode otherwise your build will fail to install onto the device. Then type
./cordova/run [platform] where platform can by
This will go through the install process and perform the various tasks that a BlackBerry app needs to install on your device. You will need an internet connection since your apps will need to be signed with the BlackBerry server. Once that’s done, it should install on your device. To note, the basic
./cordova/run command will also instantiate debug mode so you can use the remote web inspector to debug your application. You will find this to be immensely useful in figuring out errors on your device. The default url should be at
126.96.36.199:1337. So if you type that into your computer’s address while it’s hooked up to your device over USB, it should launch the remote web inspector.
I hope this guide helps you in your BlackBerry developing endeavors!
