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! :)
