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);

Click Handler Android Java example source code. Open new class as activity and open URL in browser.
In layout.xml file:

 android:layout_height="wrap_content" android:onClick="@string/clickHandler">

In string.xml

myClickHandler

In MainClass.java file

	public void myClickHandler(View view) {
		switch (view.getId()) {
		// open new class as activity
		case R.id.btnOpenClass: {
				Intent pictureActivity = new Intent(getBaseContext(),
						MyClass.class);
				startActivity(pictureActivity);
		}
		break;			
			
		case R.id.btnAbout: {
			//aboutDialogCreate();
		}
			break;
			
		// open url	
		 case R.id.btnHome: {
		 String url = "//android.okhelp.cz/";
		 Intent i = new Intent(Intent.ACTION_VIEW);
		 i.setData(Uri.parse(url));
		 startActivity(i);
		 }break;

		}

	}// end myClickHandler

// listener .. if click on button will scrolling to mTextView bottom
private OnClickListener mButtonListener = new OnClickListener() {
	    public void onClick(View v) {
	      // do something when the button is clicked
	    int nBottom =	mTextView.getBottom();
	    hScrollView.scrollTo(0, nBottom);
	    }
	};
