when i click back button password and username still there

[sam liya]

in my app when i login it goes to home page.when i am in home page if i click back button it goes to login page,but username and password is still there.What is the stander ed way to avoid this ?

[Ulf Dittmer]

Removing it after login, of course. As long as you think about "pages", that's the wrong metaphor. Think about activities instead (in the Android sense of the word).

i tried with below.Anyway its working fine.But i think username should be there in login screen.

@Override
	public void onBackPressed() {
		Intent intent = new Intent(getApplicationContext(), LoginActivity.class);
    	startActivity(intent);
	    return;
	}

Starting a new activity doesn't remove the credentials on the old one, you'll just end up with two login activities. Why don't you just finish the login activity after you're done with the login? Is there a point in keeping it around after a successful login?

[sam liya]

your suggestion if better ULF,but in future i am going to implement the Stay signed facility.

[Ulf Dittmer]

What's a "stay signed facility", and what is its relationship with what happens to the login activity after a successful login?

[sam liya]

Stay signed in means hen user login it reminds the user crerdentials.when next time it run no needs to enter username and password.

[Ulf Dittmer]

In that case there really is no connection between that, and what happens to the login activity (which may thus safely be terminated).

Thanks ULF,anyway please tell me how to enable the Signed in facility in android,i think to use preference .is it better?
