i hope u did a ionic build android / ios before deploying…
all the changes made to www folder (in the project root and NOT the one inside platform folder ) would require a ionic build to implement changes. Also on android its better to remove(uninstall) the APK from the emulator and on eclipse do a clean , and then run on emulator, sometimes the apk in NOT reinstalled without the clean
