Properly skip login activity if already logged in

Question

My launcher icon currently starts the login activity. I\'ve stored the logged in status in SharedPreferences. Is there any way to properly skip the login activi

Answer 1

You can create a Base Activity that will check if the user's username and password is already in the SharedPreferences and starts the activity if it exist hence not.

example:

public class BeanStalkBaseActivity extends SherlockActivity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);


    if(SavedPreference.getUserName(this).length() == 0)
    {
        Intent intent = new Intent(this,LoginActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        finish();
        startActivity(intent);
    }else
    {
        Intent intent = new Intent(this,MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        finish();
        startActivity(intent);
    }

}

}

BeanStalkBaseActivity should be your Launcher as it only serve as a checker.
