I'd like to ask you a question about payment for Android in-app.

        Intent in = new Intent();
        in.putExtra(PAC_INDEX,pIndex);

        Bundle buyIntentBundle = mService.getBuyIntent(3, context.getPackageName(),
                id, "inapp", publicKey);
        PendingIntent pendingIntent = buyIntentBundle.getParcelable("BUY_INTENT");
        ((Activity)context).startIntentSenderForResult(pendingIntent.getIntentSender(),
                BUY_ITEM, in,Integer.valueOf(0), Integer.valueOf(0),
                Integer.valueOf(0));
