I have created this page as a work in progress for people like me who only have the emulator to develop on.

Below is a list of differences between the Pre and the SDK emulator.

Differences Currently, the emulator does not support the following:

Accelerometer live data (does support orientation and shaking events)


Bluetooth (UI and any interface-specific APIs do not work in the emulator)


Gesture area




Wi-Fi (UI and any interface-specific APIs do not work in the emulator, but network connectivity works by using the desktop connection)


Messaging does not work on the SDK emulator. (Install http://forums.precentral.net/homebrew-apps/205914-messaging-plugins-live-yahoo-icq.html to make this work)

File System

File system is read only on the Palm Pre. File system is read/write on the SDK emulator.


Palm Pre architecture is armv7. SDK Emulator architecture is i686.


There is no sound in the SDK emulator. You can find a test four sound in the SDK here : how to copy mp3 files in Palm Pre emulator SDK http://forums.precentral.net/webos-apps-software/223899-how-copy-mp3-files-palm-pre-emulator-sdk-translate-music-player-r-french.html
