what is the best way to add a log out button in android?
I tried with kill the activity? is it good way ?

What does "log out" mean for the app? Into what would a user be logged in?

[shawn peter]

i have no clear idia about log out in android as android doesn't maintain session like Web.

[Ulf Dittmer]

Well, if you can't articulate what being logged in means, then it's impossible to advise how logging out might work.

Ideally the app should have (at a minimum) two sets of functionality. One which is available to logged in users and the second to all users (Of course this is generic, and would solely depend on what your app does)
Logging out would typically take the user to the non logged in functionality screen which can be anything (welcome screen, login screen, whatever.) Again it depends on your application.
Since you are the only one who knows what the application does, its for you to decide.

in my app users must login to do anything.But my problem is how to log out after login. Currently i am clicking back button and go to login page.

Which brings us right back to this still unanswered question:

user loged into aapplication.

Okay. That was easy after all. So, your logout button should either end the application or take the user to the login page. That would be your choice.

1)how to end the application?

2) i tried with direct to login page.But my username and password already there ?how to remove them when i direct to login page ?

[Maneesh Godbole]

From the login screen before you start the next activity, clear the login / password so that when the user comes back, its blank.

thanks

when i direct to login page it work fine.Anyway when i try to login again iti didn't login.I think its related to Oncreate method as it doesn't run twice.

below is my login code

Button login = (Button) findViewById(R.id.btnLogin);
		Email = (EditText) findViewById(R.id.ETEmail);
		Password = (EditText) findViewById(R.id.ETPassword);

		login.setOnClickListener(this);


@Override
	public void onClick(View v) {

		Global global = ((Global) getApplicationContext());

		String txtusername = Email.getText().toString();
		String txtpassword = Password.getText().toString();

		global.setUsername(txtusername);

		String userType = checkUserType(txtusername);

		if (txtusername != null & txtpassword != null) {

			if (userType.equalsIgnoreCase("PM")) {
				Toast.makeText(this, "Login Successful", Toast.LENGTH_LONG)
						.show();
				Intent i = new Intent(getApplicationContext(), PM_Home.class);
				Email.setText("");
				Password.setText("");
				startActivity(i);
			} else if (userType.equalsIgnoreCase("NU")) {
				Toast.makeText(this, "Login Successful", Toast.LENGTH_LONG)
						.show();
				Intent i = new Intent(getApplicationContext(),
						Member_Home.class);
				Email.setText("");
				Password.setText("");
				startActivity(i);
			}
		} else {
			Toast.makeText(this, "Login Error", Toast.LENGTH_LONG).show();
		}
		// if(Email.e)
