Почему служба Android аварийно завершает работу с NullPointerException?

Вот код:

public class BillingService extends Service implements ServiceConnection {
...
    @Override
    public void onStart(Intent intent, int startId) {
        handleCommand(intent, startId); // line 361
    }

    /**
     * The {@link BillingReceiver} sends messages to this service using intents.
     * Each intent has an action and some extra arguments specific to that action.
     * @param intent the intent containing one of the supported actions
     * @param startId an identifier for the invocation instance of this service
     */
    public void handleCommand(Intent intent, int startId) {
        String action = intent.getAction();
        if (Debug.Yes) {
            Log.i(TAG, "handleCommand() action: " + action);
        }
        if (Consts.ACTION_CONFIRM_NOTIFICATION.equals(action)) {
            String[] notifyIds = intent.getStringArrayExtra(Consts.NOTIFICATION_ID);
            confirmNotifications(startId, notifyIds);
        } else if (Consts.ACTION_GET_PURCHASE_INFORMATION.equals(action)) {
            String notifyId = intent.getStringExtra(Consts.NOTIFICATION_ID);
            getPurchaseInformation(startId, new String[] { notifyId });
        } else if (Consts.ACTION_PURCHASE_STATE_CHANGED.equals(action)) {
            String signedData = intent.getStringExtra(Consts.INAPP_SIGNED_DATA);
            String signature = intent.getStringExtra(Consts.INAPP_SIGNATURE);
            purchaseStateChanged(startId, signedData, signature);
        } else if (Consts.ACTION_RESPONSE_CODE.equals(action)) {
            long requestId = intent.getLongExtra(Consts.INAPP_REQUEST_ID, -1);
            int responseCodeIndex = intent.getIntExtra(Consts.INAPP_RESPONSE_CODE,
                    ResponseCode.RESULT_ERROR.ordinal());
            ResponseCode responseCode = ResponseCode.valueOf(responseCodeIndex);
            checkResponseCode(requestId, responseCode);
        }
    }
