title: Android simple alert dialog
body: <p>I need to show a little text message to the users that clicks a button on my Android app, on IOS I just had to create an AlertView that it's simple to use but with Android i'm struggling because the solution seems x10 times harder. I saw that I need to use a DialogFragment but I can't understand how to make it work, can someone explain? Also, is my solution right or there is something easier to show a simple text message to users?</p>
