Hi,
The thing is, if I create an Activity it always will show something on
the screen, rigth?
Even if I do not set any view, like in this code, it always appear the
black screen of the activity. I can call to finish as soon as I read
the tag and I show the toast, but it is not nice.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.main)
}
When you say not to load any xml what do you mean really? It would be
great not to show nothing on screen, just the toast and then call to
finish and the user would not realize that an activity has been
opened.
I am a bit new to Android, so if you can explain me more in detail it
would be great.
Thanks for your time.
