I've an application that you can show and close several Dialogs with:

showDialog(...)
removeDialog(...)

I play a little bit with the application and when there is no any Dialog on the screen, I press the menu button and I go to the main android screen.

After a while, I enter again into my application and sometimes, I get this RuntimeException:

java.lang.IllegalArgumentException: Activity#onCreateDialog did not create a dialog for id 4

Any idea?

Thank you very much.

UPDATE, more information:

The current onCreateDialog implementation is:

protected Dialog onCreateDialog(int id){
 Builder b = new AlertDialog.Builder(this);
 if(id == 4){
  b.setMessage(...);
  b.setItems(items, new DialogInterface.OnClickListener(){
   public void onClick(DialogInterface dialog, int which){
    Intent i = new Intent(Current.this, Another.class);
    startActivity(i);
   }
  });
  return b.create();
 }
 return null;
}

In order to call this function I do:

removeDialog(4);
showDialog(4);

In API level 8, onCreateDialog(int) was deprecated in favor of onCreateDialog(int,Bundle). If you implement only the latter method and run the app on a device with an API level lower than 8, you get the described error message.

The solution is to implement onCreateDialog(int)
