Maybe it's just because I'm trying to learn how to integrate Facebook into Android before becoming fluent in Android, but figuring out exactly HOW Facebook wants you to authenticate is extremely frustrating. This code (called from my MainActivity)
code:Session s = new Session.Builder(this).setApplicationId(APP_ID).build();
s.openForRead(new Session.OpenRequest(this));

Thanks for getting back to me.
I pulled it out into another method and created a button to execute it. Same error.

Are you really teaching an intro CS class with Android? That sounds horrible.

I have a spinner with this XML
code: <Spinner
android:id="@+id/spinner1"
android:entries="@array/electronics"
android:prompt="@string/select_device"
android:layout_width="216dp"
android:layout_height="wrap_content" />
I tried this and it didn't work; the spinner is completely blank:
code: electronics = new Spinner(context);
electronics.setId(ELECTRONICS_ID);
electronics.setPrompt(context.getString(R.string.select_device));
ArrayAdapter<String> electronicsAdapter = new ArrayAdapter<String>(context, R.layout. R.array.electronics);
electronicsAdapter.setDropDownViewResource(ELECTRONICS_ID);
electronics.setAdapter(electronicsAdapter);
LayoutParams electronicsLayoutParams = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
