public class SignInActivity extends Activity {
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sign_in);
    }

    @Override
    protected void onResume() {
        super.onResume();
        if (Twitt4droid.isUserLoggedIn(this)) {
            startActivity(MainActivity.makeIntent(this));
            finish();
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        switch (requestCode) {
            case WebLoginActivity.REQUEST_CODE:
                switch (resultCode) {
                    case RESULT_OK:
                        startActivity(MainActivity.makeIntent(this));
                        finish();
                        break;
                    case RESULT_CANCELED: break;
                }
                break;
           default: super.onActivityResult(requestCode, resultCode, data);
        }
    }
}

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <com.twitt4droid.widget.LogInOutButton
        android:id="@+id/log_in_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

• Create an Activity called HomeActivity:

public class HomeActivity extends FragmentActivity {

    private LogInOutButton logoutButton;
    
    public static Intent makeIntent(Context context) {
        return new Intent(context, HomeActivity.class);
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        logoutButton = (LogInOutButton) findViewById(R.id.log_out_button);
        logoutButton.setOnLogoutListener(new LogInOutButton.OnLogoutListener() {
            
            @Override
            public void OnLogout(LogInOutButton button) {
                finish();
            }
        });

        getSupportFragmentManager()
            .beginTransaction()
            .replace(R.id.content_frame, HomeTimelineFragment.newInstance())
            .commit();
    }
}

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <com.twitt4droid.widget.LogInOutButton
        android:id="@+id/log_out_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_margin="8dp" />

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@id/log_out_button" />

</RelativeLayout>

• With this you have simple login/logout app with the home timeline.
• Download the source code (Import it in Eclipse as Existing Android Code Into Workspace)

Check out the code in the app/ folder.
