Hi all,

I have an issue with the Linking Activities Using Intents 'try it out'.

I have created the code and it runs on the emulator, except that I can't close the program down with the Back button. So when I have the Activities screen displayed and I press the Back button nothing happens.

The same behaviour is true of the sample code that I have downloaded.

Does anyone else see this problem and is there a solution?

My emulator is running as Android 2.3.3

Thanks in advance

OK I worked it out myself - why do you have to post a question, to them work out what you need to do.

The problem is caused by the onKeyDown() that is stopping normal behaviour working. So in the MainActivity.java file the relevant code should be:

Code:

    public boolean onKeyDown(int keyCode, KeyEvent event) {
    	if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
    		startActivity(new Intent("net.learn2develop.ACTIVITY2"));
    		return false;
    	}
    	return super.onKeyDown(keyCode, event);

Now I can close my app by pressing the back button.
