IllegalArgumentException：InAppBilling

Question

当我在OnCreate中使用这行代码时：

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

App无法启动，Logcat告诉我：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.niclas.myapplication/com.example.niclas.myapplication.MainActivity}: java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { act=com.android.vending.billing.InAppBillingService.BIND 

我该如何解决这个问题？如果需要更多代码，我将编辑我的问题。

我想在这个上下文中使用这一行代码：

ServiceConnection mServiceConn = new ServiceConnection()
{
    @Override
    public void onServiceConnected(ComponentName name, IBinder service)
    {
        mService = IInAppBillingService.Stub.asInterface(service);
        Log.d("TEST", "mService ready to go!");
        checkownedItems();
    }

    @Override
    public void onServiceDisconnected(ComponentName name)
    {
        mService = null;
    }
};

private void checkownedItems() {
    try {
        Bundle ownedItems = mService.getPurchases(3, getPackageName(), "inapp", null);

        if (ownedItems.getInt("RESPONSE_CODE") == 0) {
            ArrayList<String> ownedSkus = ownedItems.getStringArrayList("INAPP_PURCHASE_ITEM_LIST");
            ArrayList<String> purchaseDataList = ownedItems.getStringArrayList("INAPP_PURCHASE_DATA_LIST");
            ArrayList<String> signatureList = ownedItems.getStringArrayList("INAPP_DATA_SIGNATURE");
            String continuationToken = ownedItems.getString("INAPP_CONTINUATION_TOKEN");

            if (purchaseDataList.size() > 0) {
                //Item(s) owned

                for (int i = 0; i < purchaseDataList.size(); ++i) {
                    String purchaseData = purchaseDataList.get(i);
                    String signature = signatureList.get(i); //Note signatures do not appear to work with android.test.purchased (silly google)
                    String sku = ownedSkus.get(i);


                }
            } else {//Item(s) not owned

                String base64EncodedPublicKey =
                        "myPublicKey";


                mHelper = new IabHelper(this, base64EncodedPublicKey);

                mHelper.startSetup(new IabHelper.OnIabSetupFinishedListener() {
                    @Override
                    public void onIabSetupFinished(IabResult result) {
                        if (!result.isSuccess()) {
                            Log.d("TEST", "In-app Billing setup failed: " + result);
                        } else {
                            Log.d("TEST", "In-app Billing is set up OK");
                        }
                    }
                });
            }
        } else {
            //Error checking owned items
        }
    } catch (RemoteException e) {
        e.printStackTrace();
    }
}
