Q1) Using Android Studio do the following:
a) Run Second Activity Demo and Basic Components, use bitbucket.org to get files.
b) Build APK files.
c) Modify and/or create java code in the MainActivity.java file so that the interface widget implements some "Action" when the application runs.
For example, you might create a simple button, that, when clicked, changes color. Or, you might have a text field that when a button is clicked, the text changes in some way (i.e., is stored, is deleted, etc...). Also, be sure to study and understand how the widgets that you create are described in the activity_main.xml file (This step has to be implemented effectively).
d) Attach screenshots of the following project elements and upload
1.Test of application
2. Activity_main.xml (code and design)
3. MainActivity.java (code)
4. Other screenshots as necessary
