Task: Create a Hello World application TextField: “Hello World” Add a button below the text Set the text of the button On button click change “Hello World” to “Goodbye world!” When in landscape layout, the place the button to the right of the text !!!State not saved between reorientations!!! android:configChanges= "orientation|screenSize“ application class; global variable public Object onRetainNonConfigurationInstance() getLastNonConfigurationInstance() setRetainInstance() -- Fragments

Is default in Android 3.0 or higher (API level >= 11)

<activity … android:parentActivityName="com.example.myfirstapp.MainActivity" public void onCreate(Bundle savedInstanceState) { … getActionBar().setDisplayHomeAsUpEnabled(true); //getSupportActionBar().setDisplayHomeAsUpEnabled(true); }

Task 1: Add Style Create another button below the first button only for the portrait orientation Add background image and set a text color for the first button Add a background color and change the font style for the second button Task 2: Add Functionality Create another activity with only a TextView Implement the Up button Remove the settings menu Add a “Exit” menu to both activities Add “Toggle Font” menu to the new activity: Switches between Bold and Normal text in the TextView Intent intent = new Intent(Intent.ACTION_MAIN); intent.addCategory(Intent.CATEGORY_HOME); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(intent); Intent intent = new Intent(this, com.example.helloworld.SecondActivity.class) startActivity(intent);

Download and run FragmentExercise application Add the details fragment for the portrait orientation Change the program so you use only dynamic fragments Add a fragment to the bottom displaying the logo Add transition animation to fragments -> setCustomAnimations(int, int, int, int) FragmentTransaction transaction = getFragmentManager().beginTransaction(); getFragmentManager().findFragmentByTag("details"); transaction.replace(R.id.portraitLayout, fragment, "details");

Create a new Android Application that has the following functionality When the application starts it shows a splash screen (video) Then the camera starts The user takes a picture Then a game of “Whack-A-mole” starts the background is the picture previously taken every 10 seconds the user has a special skill that allows to slash. There is a message that shows when this skill is available (FRAGMENTS!!!) Every action creates a different sound (mole hit, mole missed, slashing)
