title: How to detect if my app was uninstalled?
body: <p>I understand that this question has been asked a number of times. But I would like to know if I can open a webpage after my app is uninstalled. </p>
  
  <p>Before you say no, Please note that there are some apps like apus launcher which can detect when their app is uninstalled and can open a webpage after uninstall. </p>
  
  <p>Thanks a lot</p>
