The concept is controversial! There is a package in android called widget, which contains all the controls provided by android, such as listView, TextView, EditText, Button, etc. We can say that these are widgets in android.
When it comes to this, someone must ask, what is the name of the android desktop applet? I tell you, android desktop applet can be called APP widget! In most cases, widget refers to a desktop applet!
For me, it is first understood as a control.
