Emulator

Introduction
The webOS SDK includes an emulated webOS device that runs as a virtual machine (VM) in VirtualBox. Using the emulator allows you test applications you develop without the need for a physical device. The emulator also offers some advanced debugging tools not available when running on a device.
Getting Started
To launch the emulator start the palm-emulator command line tool. This command will start VirtualBox and the webOS virtual machine.
Once the emulator is started, you can access its terminal directly by opening up a command window and entering:
novacom -t -d emulator open tty://
Common Emulator Problems
If you allow VirtualBox to suspend the VM that is running webOS you will not be able to connect with the command line tools or Palm Inspector. To fix this, reboot the VM.
Advanced Techniques
Copying Files To The Emulator
On a Mac or Linux PC you can easily copy files to the emulator using the scp command:
scp -P 5522 <local filename> root@localhost:<remote filename>
Root's password is empty (just press enter when prompted). On Windows you must first install WinSCP. To configure WinSCP for Windows, use the following settings:[1]
Host Name: 127.0.0.1 (localhost will not work) Port: 5522 User Name: root File Protocol: SCP Click OK to enter a blank password Click OK to the error that comes up You will also get a warning about the connection, just continue.
Changing The Language
You can test localization of your apps by changing the emulator's language.[2] To change the language, navigate to the third page of apps on the emulator and choose Region Settings. From here you can select the language to test. There is a special English variation called 'Pseudoland' that creates randomized strings for Palm-translated strings so you can see which strings Palm translates for you.
Enabling Sounds
- Note: This only works for .wav and .pcm files.
mv /etc/event.dis/audiod /etc/event.d mv /etc/event.dis/mediaserver /etc/event.d mv /etc/event.dis/pulseaudio /etc/event.d mv /etc/event.dis/systemsoundsloader /etc/event.d
