There's not a lot of clear information on this error from Google (error in the dex file optimization process.)  There seem to be quite a few folks on the web that have encountered it...reading some of these the common thread appears to be stale files or app install entries that cause Android to think the app is in partially installed/uninstalled state.
 
Some suggestions:
 
Delete data, cache and any instances of connectgb or connectgb-1 apps in Manage Applications.
 
delete /system/sd/app/connectgb*

delete the directory /data/data/connectgb*
delete /data/app/com.connectgb*
edit /data/system/packages.xml removing all entry for connectgb*
 
ADB pull /data/data/com.android.vending/databases/assets.db to a computer,
then open it with a sqlite editing too. Look in the assets10 table for the
row where field package_name matches your apk name, update the field to 'UNINSTALLED'. Push the assets.db file back to its original location,
and reboot.
 
(Some or all of these may fail due to permissions on the Cius, advice gleaned from XDA forums here http://forum.xda-developers.com/showthread.php?t=580303)
 
Keep in mind it looks like both connectgb.apk and connectgb-1.apk may have gotten installed at some point.
 
If none of this helps, a factory reset (or Wipe Data in the emulator) should put everything back to original condition.

Hi all

Unfortunately none of these worked for me. I'd solved my problem by reinstalling Android sdk, Eclipse and cius emulator and also created a new project.

Thanks
