Passing extras from Activity to Intent throws NullPointerException

This is a problem that forked off a different issue.

I'm passing two strings from my main activity to a child service, which is fine, but when the main activity dies, the service throws a NullPointerException trying to grab the two strings.

From MainActivity:

Intent i = new Intent(this, PebbleService.class);
i.putExtra("quote", quote[0]);
i.putExtra("author", quote[1]);
startService(i);

From PebbleService:

public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);

    final String author = intent.getStringExtra("author");
    final String quote = intent.getStringExtra("quote");

    // Define AppMessage behavior
    if (appMessageReciever == null) {
        appMessageReciever = new PebbleKit.PebbleDataReceiver(WATCHAPP_UUID) {

            @Override
            public void receiveData(Context context, int transactionId, PebbleDictionary data) {
                // Always ACK
                PebbleKit.sendAckToPebble(context, transactionId);

                // Send KEY_QUOTE to Pebble
                PebbleDictionary out = new PebbleDictionary();
                out.addString(KEY_QUOTE, quote);
                out.addString(KEY_AUTHOR, author);
                PebbleKit.sendDataToPebble(getApplicationContext(), WATCHAPP_UUID, out);
            }
        };

        // Add AppMessage capabilities
        PebbleKit.registerReceivedDataHandler(this, appMessageReciever);
    }

    return START_STICKY;
}
