Run your app on a phone

You’re almost there; you’ve coded your app and tested it in an emulator to confirm it works as expected. It’s now time to get the app running on a phone. You do this by copying the app’s JAD and JAR files to your phone then installing and running the app, this section explains how.

Please note that the video shows the Nokia Asha SDK 1.0 — the steps and actions are still applicable to the Nokia Asha SDK 1.2.

  1. Package your MIDlet using the Create Package option in the project overview.
  2. Copy the packaged app to your phone.
  3. Install the app on the phone.
  4. Run the app on your phone.
  5. Test your app to ensure it complies with Unified Testing Criteria of the Java Verified Initiative.

Step-by-step — Run your app on a phone

Step 1 — Package the app

First you have to package the MIDlet, which you do by clicking Create package in the MIDlet project’s overview page.

In the MIDlet Package Export dialogue select the Use Deployment directory option.

Click Finish, and your app’s packages are built and saved into the MIDlet project.

Step 2 — Copy your app to your phone

You can now deploy the app to your phone. These instructions apply to a Nokia Asha platform phone, but a similar process can be used for other Asha and Series 40 phones. First connect your phone to your PC using a USB cable and, when prompted, select the Mass storage option on the phone. From the Projects list in Nokia IDE for Java ME copy your app’s JAD and JAR files to the my_downloads folder on the phone’s memory card. Once the files have been copied, disconnect the phone from the USB cable.

You can also send the files over a Bluetooth connection if you wish.

Step 3 — Install the app on your phone

Now you need to install the application. To do this, on your phone open the Files app then locate the app’s JAD file in the Downloads folder of the Memory card. Tap the JAD item to start the installation process.

If you used a Bluetooth connection to transferred the files they’ll be listed in the timeline home screen and can be installed from there.

Step 4 — Run your app

You can now run the app from on the phone’s App launcher home screen, as shown below, simply scroll down to find your app then tap your app to run it.

Java Getting Started figure 15

You have now seen how to create an environment for developing Java app for Nokia Asha platform phones. You installed the Nokia Asha SDK, created a MIDlet from a template in the Nokia IDE for Java ME, ran it in the SDK emulator, and then copied and ran the same app on your Nokia Asha platform phone. You’re now ready to use your Java skills to create applications for Nokia Asha platform phones.

Step 5 — Test against the Unified Testing Criteria

While you don’t need to undertake any additional testing to complete this getting started, when you are building your first real app you’ll need to ensure it complies with Unified Testing Criteria of the Java Verified Initiative.
