Dropdown not dismissed on back pressed of device -android

Yes, that may be the case.

Do you also have a question or a problem to be solved?

Is is a problem to be solved.
Dropdown is not dismissed on press back button of device.

there is no solution for that issue

So you want that the dropdown (what element are we talking about?) is dismissed when someone tabs the Android back button, correct? If so: Implement a handler for the back button, emit an event (if there not even is already one), handle the event by dismissing the dropdown.
