Question

That might be broad question but I will try to explain best. I will also give code snippets if anything jumps out – please let me know.

I can’t repro this issue but it surface itself like so:

a. Sometime I would be logged in – I hit log out and will see my Activity refreshed. And that can happen many times. What I expect is Activity to close when I hit logout.

b. Sometime I’m on my Activity (already logged in) and started from icon. And I click back and it wouldn’t go to “desktop” and goes to activity again. And this can happen 1-3 times. I expect since this is main activity to go back to desktop when hit back.

c. I noticed similar kind of issue on Yahoo mail app so I’m not sure if that is bug or 2.3.1 issue on my Nexus S?

I have:
1. Main activity
2. Login dialog that is custom dialog.

This is code from my activity:

public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        //If not authorized yet then show sign in dialog
        if (!PreferencesManager.getIsUserAuthenticated(getApplicationContext()))
        {
            showDialog(1);
        }

        Button signOutButton = (Button) findViewById(R.id.SignOutButton);
        signOutButton.setOnClickListener(new View.OnClickListener()
        {
            public void onClick(View view)
            {
                PreferencesManager.setIsUserAuthenticated(false, getApplicationContext());
                **MainActivity.this.finish();**
            }
        });


    }

    @Override
    protected void onDestroy()
    {
        super.onDestroy();

    }

    @Override
    protected void onPause()
    {
        super.onPause();
    }

    protected Dialog onCreateDialog(int id)
    {
        LoginDialog dialog = new LoginDialog(this);

        dialog.setOnDismissListener(new DialogInterface.OnDismissListener()
        {
            public void onDismiss(DialogInterface dialog)
            {
                if (!PreferencesManager.getIsUserAuthenticated(getApplicationContext()))
                {
                    **MainActivity.this.finish();**
                }
            }
        });

        return dialog;
    }

In dialog class – I have regular stuff and “this.dismiss” if Login was successfull.

Your activity is somehow getting created multiple times. This can be do to how it’s being run, if it’s a shortcut from your desktop or the app drawer, or holding home, or some other shortcut.

You might want to look into launchMode at http://developer.android.com/guide/topics/manifest/activity-element.html
