This post describes how to develop your first QML application on Nokia N9. Unfortunately I have only instructions for Mac users but I assume the steps for other platforms are similar to this.

Setting up environment on your Mac

• Install Xcode (4GB).
• Install Qt SDK (1.2GB).
• Activate developer mode on N9 (Settings > Security > Developer mode). This may take some time to complete. Please make sure the device can access to the internet. It needs to download some applications.
• Also install “Examples” in the Developer mode. You can see almost at the bottom of the screen.
• Settings on Qt Creator
  • • Go to Qt Creator > Preference
    • Click Linux devices section
    • Click “Add” to select Device with MADDE support
    • Give a name to this configuration. e.g MyN9
    • Select “MeeGo 1.2 Harmattan”
    • Select “Hardware Device as the kind of device
    • Do not edit IP address and SSH server port.
    • Press Continue
    • And press “No” in the next dialog. They ask if you already have a passcode.
    • Check Create key and press continue. You will create a passcode to access to N9 from your PC. The passcode is saved to the PC thus you don’t need to type it manually from the PC.
    • Click Create key in the next dialog and press continue
    • It shows “Creating keys … Done” then press continue.
    • Now you need to copy Password from N9.
  • N9
    • Connect N9 and your PC with USB and select SDK mode if dialog appears. If not go to Setting application > Accessories > USB and click “Always ask”. Then disconnect USB and connect it again.
  • Mac OSX
    • You will be asked to open Network window in System Preference on your PC and press apply to add the N9
  • N9
    • Launch SDK connection app and select USB on the N9
    • You can find password on your screen
• Qt Creator
• Go back to the current Qt Creator preference
• Type the password into the dialog on Qt Creator preference and press deploy key
• It shows “Deploying … Done.”
• Press continue and it will automatically check if the configuration works with the N9.
• Press Close if it says “Device configuration okay.”
• Close all preference windows on the Qt Creator
• Update Qt Creator
• There might be an update for Qt Creator. Open Updater by Help > Start Updater. Do this a couple of times.

First QML application on N9

• Create a project (File > New file or project)
• Select Qt Quick Application in Qt Quick project section
• Give a name to the project and press continue. Please use lower cases for all letters. Otherwise it will give a waring when building the app.
• Select Qt Quick Components for Meego/Harmattan and select continue
• Select only Harmattan for the target setup and select continue. You don’t need Qt Simulator either Desktop.
• You can choose your own app icon and press continue
• Keep version control as none and press done
• Qt Creator generates files and press yes in the dialog
• You don’t need to edit the code at all. Just run the code (Build > Run)
• N9 launches your Hello World application after while

Some tips

• When you open this project files in the Qt Creator, open <project name>.pro under <project name> folder.
• Press a small red square button at the bottom of the Qt Creator window to close the app on N9.
