Login screen: Save username and password
<p>After deciding to get some exposure to android app, i started playing with it but being new to java and new environment is a good learning curve. However after many hours I was able to get the basic android app going. Now I have another dilemma. I dont have a login screen. I can connect to database just fine but I want users to enter their login one time when they start the app. I have these questions</p>

<ol>
<li><p>Any good tutorials that I can find where there is a login screen that I can add on top of the work I already got done and once they login, they get directed to those files</p></li>
<li><p>How do I set the menus. Like if the users setup the login one time and later on they want to change it and use another login, how would I go about setting those?</p></li>
</ol>

<p>Any links to good tutorials about this will be very appreciated</p>
