Question

I have a question regarding android activity.

I have my first loginscreen(MainActivity) and from there go to Secondscreen, now when I am pressing escape button from the secondscreen I want to close the application(or android home screen) and next time open the application I want to start application with secondscreen.

i tried this code on my second screen but it does not working

public boolean onKey(DialogInterface dialog, int keyCode, KeyEvent event) 
{
    if (keyCode == KeyEvent.KEYCODE_BACK || keyCode == KeyEvent.KEYCODE_ESCAPE)                                 
    {      

        //My logic here

        return true;
    } 
    return false;
}

Answer 1

What I assume you are trying something like below:

Frist installation#

LoginScreen>SecondScreen, when you press escape it will close entire app.

Second Time#

When you open app it will start from second screen instead loginScreen.

Solution

Phase1#

Store your login info in database or sharepreference when first time login has been made, and finish() loginscreen while opening second screen.

Phase2#

When you open second time your app, check your login info, if it is exists then redirect to second activity else open loginScreen.
