Running Projects Simultaneously on a Single Device

MSA-compliant devices are capable of running multiple virtual machines.You can test this behavior in the emulator. Be sure the output window is visible in the SDK (select Window > Output > Output). To test this feature, follow these steps:

1. Open the sample projects Games and AudioDemo.

2. In the device selector, choose an MSA-compliant device and run Games. When the emulator launches run AudioDemo on the same device.

   As each MIDlet loads, the AMS automatically launches it.

3. In AudioDemo, launch the Audio Player, and play the JavaOne theme.

   Select AudioPlayer, then from the soft menu, select 1, Launch. Select JavaOne Theme and press the Play soft button.

   Select SunSamples - Games. From the soft menu, select 1, Open. The music continues to play while you are able to simultaneously launch and play games.

5. Select Application > AMS Home, or press F4. Highlight AudioSamples, and from the soft menu, select 2, Bring to foreground. Press the Pause soft key. The music stops playing.
