Which statements are true for the Parcelable interface?

Which of these methods are called when the screen changes orientation from portrait to landscape in Android?

Consider the following code:

@Override
protected void onResume() {
    super.onResume();
    mp = MediaPlayer.create(getBaseContext(), R.raw.sound);
    Thread timer = new Thread() {
        @Override
        public void run() {
            try {
                Thread.sleep(1000);
                Intent main = new Intent(Splash.this, MainActivity.class);
                startActivity(main);
                finish();
            } catch (InterruptedException e) {}
        }
    };
    timer.start();
    mp.start();
}

@Override
protected void onPause() {
    super.onPause();
    if (mp != null) {
        if (mp.isPlaying()) {
            mp.stop();
        }
        mp.release();
        mp = null;
    }
}

Select the statements that are correct if the wave file sound is 3 seconds long.

Consider the following image:

Fill in the blanks in the following layout so that it renders like the image above:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="_____________">
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="_____________">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:padding="5dp"
                android:text="User"/>
            <TextView

        </LinearLayout>
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="_____________">
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:padding="5dp"
                android:text="Address"/>
            <TextView
                android:layout_width="wrap_content"

                android:text="Secondary address"/>
        </LinearLayout>
</LinearLayout>

Fill in the blanks, so that changes in the shared preferences are saved:

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", MODE_PRIVATE);
Editor editor = pref.______();
editor.putString("start_message", "Hello!");
editor.putString("end_message", "Goodbye!");
editor.________();
