Ionic run android is not building apk

I shifted development of my ionic app from windows to ubuntu 14.04 now. I installed everything new. “Ionic build android” command is working but when i run “ionic run android” or “ionic emulate android” it only starts emulator no BUILD SUCCESS and LAUNCH SUCCESS is shown in console. Also app does not get installed in emulator.

ajeet@samsung:~/deployments/mobile_app/chmapp$ ionic run android
Native thread-sleep not available.
This will result in much slower performance, but it will still work.
You should re-install spawn-sync or upgrade to the lastest version of node if possible.
Check /usr/lib/node_modules/ionic/node_modules/ionic-app-lib/node_modules/cross-spawn/node_modules/spawn-sync/error.log for more details
