Your phone’s android version should be >= minimum android version required by ionic. Probably you are using an older phone.

You deploying you application on device ? Or emulator ? I will suggest you to use genymotion emulator. Its very easy to use and have many features as per comparison to android emulator, And you can test your application with different android versions.
