The Android runtime is entirely correct.
This code:
public class SubLauncher extends Activity {
/** Called when the activity is first created. */
private static final String TAG = "NSubLauncher1";
public void onCreate(Bundle savedInstanceState) {
* Intent helloworldIntent = new Intent ("com.needham.helloworld", null);*
... creates the Intent using this constructor:
publicIntent(String
<http://developer.android.com/reference/java/lang/String.html>action,Uri
<http://developer.android.com/reference/android/net/Uri.html>uri)
Since:API Level 1
<http://developer.android.com/guide/appendix/api-levels.html#level1>
Create an intent with a given action and for a given data url. Note
that the action/must/be in a namespace because Intents are used
globally in the system -- for example the system VIEW action is
android.intent.action.VIEW; an application's custom action would be
something like com.google.app.myapp.CUSTOM_ACTION.
The hello world manifest does not specify an intent filter with action =
"com.needham.helloworld", thus the error.
I believe you probably meant to create your intent with explicit package
and class names. To do that, create an empty intent first, then call
setClassName(String packageName, String className).
It might find it useful to spend some time reading the docs on Intent
and intent matching.

I need to have an bootup app call another app and while the bootup app
appears to work, the second app cannot be found? The NLauncher was
derived from another thread "start at boot app gives

resolve and I thank all concerned.
I added some debug statements to help isolate the problem.
Thanks in advance to all.
