How can I populate a menu using intents?

How can I populate a menu using intents? I didn't understand that thing.

Or is there any better way for that?

Update:

Suppose I have an application that need to resize the image,and there are many other applications that have a capability of resizing the image. How can I show the list of applications on a menu in my application so that when clicking on a particular option it will invoke the intent associated with that application. Simply saying I could resize the image in my application with out bothering about how that will get done.

Here you have an example, using the onOptionsItemSelected that appears with the menu button you control what the menu does:

public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
      case HISTORY_ID: {
        AlertDialog historyAlert = historyManager.buildAlert();
        historyAlert.show();
        break;
      }
      case SETTINGS_ID: {
        Intent intent = new Intent(Intent.ACTION_VIEW);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
        intent.setClassName(this, PreferencesActivity.class.getName());
        startActivity(intent);
        break;
      }
}

But we create the menu with this code:

public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    menu.add(0, SETTINGS_ID, 0, R.string.menu_settings)
        .setIcon(android.R.drawable.ic_menu_preferences);
    menu.add(0, HELP_ID, 0, R.string.menu_help)
        .setIcon(android.R.drawable.ic_menu_help);
    menu.add(0, ABOUT_ID, 0, R.string.menu_about)
        .setIcon(android.R.drawable.ic_menu_info_details);
    return true;
  }
