Hi @Sahithi,

Could you please elaborate more your question. do you want to develop a application which provide background running apps information or you just want to know background running apps information in your mobile?

If you just want to know background running apps in your mobile then watch this video

OutSystems mobile applications don't have much access to system-level information like running processes due to restrictions on permissions and privacy protection. 

some device information you can get using plugins and JS code.

for example:

Device: https://success.outsystems.com/documentation/11/reference/outsystems_apis/javascript_api/device/

Kind regards,
