+
+The first meeting tutorial, building your first Android app!
+
+
+#Step 1 
+
+Installing Android Studio
+
+Go to http://developer.android.com/sdk/index.html and download Android Studio. Install it. Make sure you have the JDK
+installed on your computer: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
+
+#Step 2
+Creating a new Project
+
+Open up Android Studio and Start a new Project...

+
+Gradle should invocate your project, and take you into the activity!
+
+  
+
+#Step 2
+Adding Content
+
+
+Go to your activity_main.xml. the XML specs the appearance of the file, while the Java activities add functionality.
+Drag a Button (under Widgets) onto the screen.

+
+If you go to the Text tab in the XML, you'll be able to see the code generated by Android Studio for the Button.

+
+Run your code if you wish, and you'll see the new Button next to your Hello World!
+
+Now that we have a button, let's make it do something.
+
+
+#Step 3
+Adding functionality to your content
+
+
+Let's define a method in our MainActivity called buttonOnClick, which will execute an action when the Button is clicked.
+

+
+In this method, lets make a TextView variable that will change the Text displayed when the button is clicked.
+You can do this by first linking a TextView variable to the one being displayed, and then updating it.
+It will update when the method is called.
+

+
+Let's add a couple things to our XML to support the actions:
+If it isn't already there, add the line:
+```
+android:id="@+id/textView"
+```
+inside your TextView so that the buttonOnClick function can access and change the View.
+Additionally, add the following line:
+```
+android:onClick="buttonOnClick"
+```
+to your Button. This has your program execute the specified method when the button is clicked.
