Интеграция полосы с приложением для Android

Я пытаюсь поддерживать страйп-платежи из своего приложения для Android, но оно не запускается. Ява несовместима? Мой код и ошибки ниже:

package io.noq.kiosk.android;

import android.util.Log;

public class OnSwipeActivity extends Activity {
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Stripe.apiKey = "the secret (intentionally omitting)";
        Map<String, Object> chargeMap = new HashMap<String, Object>();

        chargeMap.put("amount", 100);
        chargeMap.put("currency", "usd");

        Map<String, Object> cardMap = new HashMap<String, Object>();
        cardMap.put("number", "4242424242424242");
        cardMap.put("exp_month", 12);
        cardMap.put("exp_year", 2013);
        chargeMap.put("card", cardMap);

        try {
            Charge charge = Charge.create(chargeMap);
            System.out.println(charge);
            Log.i("Status is: " + "exiting try onCreate-PayActivity", "let's see what goes out....");
            System.out.println("Status is: "+ "exiting try onCreate-PayActivity");
        } catch (CardException e) {
            // Since it's a decline, CardException will be caught
            System.out.println("CardException is: " + e.getCode());
            System.out.println("CardException is: " + e.getParam());
            Log.i(OnSwipeActivity.class.getName(), "e.getCode() ...." + e.getCode());
        } catch (InvalidRequestException e) {

            Log.i(OnSwipeActivity.class.getName(),"e.getCode() ...." + e.getCause());
        } catch (AuthenticationException e) {
            // Authentication with Stripe's API failed (maybe you changed API keys recently)
            System.out.println("AuthenticationException: " + e.getMessage());
            Log.i(OnSwipeActivity.class.getName(), "e.getCode() ...." + e.getCause());
        } catch (APIConnectionException e) {
            // Network communication with Stripe failed
            System.out.println("APIConnectionException: " + e.getMessage());
            Log.i(OnSwipeActivity.class.getName(), "e.getCode() ...." + e.getCause());
        } catch (StripeException e) {
            // Display a very generic error to the user, and maybe send yourself an email
            System.out.println("StripeException: " + e.getMessage());
            Log.i(OnSwipeActivity.class.getName(), "e.getCode() ...." + e.getCause());
        } catch (Exception e) {
            // Something else happened, completely unrelated to Stripe
            System.out.println("Exception: " + e.getMessage());
            Log.i(OnSwipeActivity.class.getName(), "e.getCode() ...." + e.getCause());
        }
    }
}
