Error when install ionic app on Android device

I have create my ionic app and run on Android emulator (Android 7.x).it work correctly,but when I try to install on Android box (Android 6.0.1) i got error
Make sure your testing device is on the same version of your compiled apk sdk or it is in a version ahead of it.
For example, an app built for Android 7.1.0 will not run on Android 6.1.0 but an app built for Android 6.1.0 will run on both 6.1.0 and 7.1.0 and so on.
As a default approach the newer versions of ionic cli ships aways with the latest Android sdk version, which current is 7.1.0, if youl'd like to use an older one you need to remove the platform and add it again, you can do it within these commands:
Remove the platform
ionic cordova platform remove android
Then add it again with your desired android version
ionic cordova platform add android#6.1.0
For this example I'm using the 6.1.0 version but feel free to change it to another sdk version.

how to add android and ios platform in ionic cli 3.3.0

I update ionic and trying to add android and ios platform but i could not add it. it shows me following message in console.
js20#js20:~/Desktop/project$ ionic platform add android
The platform command has been renamed. To find out more, run:
ionic cordova platform --help
My ionic version
js20#js20:~/Desktop/project$ ionic -v
3.3.0
we can simply use following commands
ionic cordova platform add android
or
ionic cordova platform add ios
to run
ionic cordova run android --device
ionic cordova run ios
ionic cordova run ios --prod --release
to build
ionic cordova build android
ionic cordova build ios
ionic cordova build ios --prod --release
If are you facing any problem while adding and removing platform.
Recently I am unable to remove and add platform using
ionic cordova platform add android
It is not get add in project.
Then finally i add platform using cordova commands
cordova platform add android
