Hi everyone. I'm teaching myself Android and it's been nothing but trouble. I'm having difficulty even doing some of the simplest tasks. Anyways, I've created a login screen, and when the user presses "OK", I want to switch activities, but it's not working. Here're my Logcat erros:

Here's my XML file I think it's referring to:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    android:name="Main Menu">
    <item android:id="@+id/set_sched_form_prefs"
        android:title="@string/set_sched_form_prefs" />
    <item android:id="@+id/set_notifications"
        android:title="@string/set_notifications" />
    <item android:id="@+id/update_calendar"
        android:title="@string/update_calendar" />
</menu>

And here's the code that's supposed to call the new Activity:

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        Button ok = (Button)findViewById(R.id.ok);
        ok.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                Intent intent = new Intent(LoginActivity.this, MainMenu.class);
                startActivity(intent);
            }
        });
    }

Does anyone have any ideas? I've done a bit of research on this error, but the only solutions I could find involved reducing image sizes, but my app doesn't have any images yet.

Thanks for your help, and have a better day than I'm having! :)

If R.layout.activity_login is the menu XML as posted above then you are doing it wrong since you cannot force menu resource instead of layout resource in place where layout resource expected. Layout have to use one of available layout classes (LinearLayout, RelativeLayout, GridLayout etc). Where menu on other hand is inflated in public boolean onCreateOptionsMenu (Menu menu)
