Solution 1:

You need to uninstall it because you are using a different signature than the original. If it is not working it might be because it is still installed for another user on the device. To completely uninstall, go to Settings -> Apps -> yourApp -> Options (the three dots on top right) -> Uninstall for all users


Solution 2:  run follwoing command that will solve   your problem

  • adb uninstall "yourApp"
  • example: adb uninstall "com.example.myapp"
