Admob testing on emulator issue.
Android Eclipse code warning:
setTesting(boolean) from the type AdRequest is deprecated
Solution:
adRequest.addTestDevice(AdRequest.TEST_EMULATOR);

AdView adView = new AdView(this, AdSize.BANNER, "a14d9..........");//MY_AD_UNIT_ID
AdRequest adRequest = new AdRequest();
		adRequest.setTesting(true); // deprecated

		adRequest.addTestDevice(AdRequest.TEST_EMULATOR); // OK
		adView.loadAd(adRequest);

GregorianCalendar cal = new GregorianCalendar(); Boolean b = cal.isLeapYear(2012); // true, Android example.

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        txtV = (TextView)findViewById(R.id.idLabel);
        cntx = this;
        StringBuilder strBuild = new StringBuilder();
        
         GregorianCalendar cal = new GregorianCalendar();
         Boolean b = cal.isLeapYear(2012); // true
         strBuild.append("Is leap year 2012? " + b + "

");
         b = cal.isLeapYear(2014);         // false
