As you are creating the app, you need to make sure you are debugging it. The tool you’ll want to use for this is the QNX Momentics IDE. This gives you a testing and debugging environment that offers you the opportunity to ensure that your code is working properly. It’s good to note that you can debug code that you have created in either C++ for QML. Make sure that you are using this tool, and debugging your code in chunks as you create the application, or you may find yourself with a lot of problems at the end.<\/p>\n

Security in Your Apps<\/h2>\n

When creating an app for BlackBerry phones, it’s important to take security into consideration. If you’re creating your app in Cascades, there are two safe string classes you can use. For ASCII strings, you can use QByteArray, and for Unicode strings, you can use QString. Keep in mind you should never use C strings when creating applications in Cascades. Be careful about the fields and paths that you use; make sure that you validate paths that come from an untrusted source.<\/p>\n
