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.

(Select all acceptable answers.)

MainActivity will be started after 4 seconds.
finish() will close the current activity.
While MediaPlayer is playing, startActivity(main) is blocked.
MediaPlayer will play only the first second of the song.
Removing the call to startActivity(main) will close the application if there are no other activities in the application's back stack.

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
