Hi Larry
It is hard to tell what is going on. It appears that when Activity2 is launched there is an error. Check the manifest file and be sure that it is correct. If you can't figure it out, post your code so we can check it.

still cant find anything that wouldn't let activity to switch to activity 2

Code:

package larryv1979.activity;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.KeyEvent;
 

public class MainActivity extends Activity {
	String tag = "Events";
	
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        
        setContentView(R.layout.main);
        Log.d(tag, "In the onCreate() event");
    }
    
    public boolean onKeyDown(int keyCode, KeyEvent event)
    {
    	if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER)
    	{
    		startActivity(new Intent("larryv1979.activity2"));
    		
    	}
		return false;
    }
    {
    	
    }
    public void onStart()
    {
    	super.onStart();
    	Log.d(tag, "In the onStart() event");
    }
    public void onRestart()
    {
    	super.onRestart();
    	Log.d(tag, "In the onRestart() event");
    }
    public void onResume()
    {
    	super.onResume();
    	Log.d(tag, "In the onResume() event");
    }
    public void onPause()
    {
    	super.onPause();
    	Log.d(tag, "in the onPause() event");
    }
    public void onStop()
    {
    	super.onStop();
    	Log.d(tag, "In the onStop() event");
    }
    public void onDestroy()
    {
    	super.onDestroy();
    	Log.d(tag, "In the onDestroy() event");
    	
    	
    	
    	
    }
}

Hi Larry
I don't see anything wrong in the code. The error says 'activity not found'.
I had the same problem. Mine was in the Manifest file. Look closely at the names of activity2, larryv1979.activity2, and what is in the Manifest file. It seems the Manifest name should be all uppercase. What I have in mine is:

MainActivity: startActivity(new Intent("net.learn2devlop.ACTIVITY2"));
Activity2: Activity2
Manifest: // new activity 2
<activity
android:label="Activity 2"
android:name ="Activity2"
>
<intent-filter >
<action android:name="net.learn2devlop.ACTIVITY2" />
<category android:name="android.intent.category.DEFAULT" />

Note the uppercase!
Hope this helps
Cliff
