Only debug.apk get installed on devices


After i build meteor app for android. I was able to install on device only the debug.apk after meteor build --debug
All the other versions have errors on installation. Are there some more steps for them to get them working??
On emulator (bluestack) it popups message “Error with Certifications”. In browsers the app working fine.

Please i would appreciate your help!!
