android - 在应用程序计费没有 ui

Question

我想学习 App Billing。我创建了一个测试应用程序。我可以使用 getSkuDetails 看到我的应用内产品已插入到 Play Console 中，但是当我启动 launchPurchaseFlow 时，购买应用内产品的界面没有启动，我只能看到日志(Log its ok)

public class MainActivity extends Activity implements View.OnClickListener {

    Button compra,click,controllo;
    private IabHelper.QueryInventoryFinishedListener mQueryFinishedListener;

    IInAppBillingService mService;

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

        @Override
        public void onServiceConnected(ComponentName name,
                                       IBinder service) {
            mService = IInAppBillingService.Stub.asInterface(service);
        }
    };

    private static final String TAG="INappBILLING";
    IabHelper mHelper;

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

        compra=(Button) findViewById(R.id.buybtn);
        compra.setOnClickListener(this);
        click=(Button)findViewById(R.id.clickbtn);

        controllo.setOnClickListener(this);



        String base64EncodedPublicKey="mykey";

我认为您的代码几乎是正确的。发生的事情是你的 mPurchaseFinishedListener 没有触发，因为你将它放在一个函数 controlloaq() 中，因此它只会在你调用 controlloaq() 时执行>.

看官方Google In App Billing sample ，你不应该将它包含在一个函数中，除非你知道你在做什么。

// Callback for when a purchase is finished
    IabHelper.OnIabPurchaseFinishedListener mPurchaseFinishedListener = new IabHelper.OnIabPurchaseFinishedListener() {
        public void onIabPurchaseFinished(IabResult result, Purchase purchase) {
            Log.d(TAG, "Purchase finished: " + result + ", purchase: " + purchase);

            // if we were disposed of in the meantime, quit.
            if (mHelper == null) return;

            if (result.isFailure()) {
                complain("Error purchasing: " + result);
                setWaitScreen(false);
                return;
            }
            if (!verifyDeveloperPayload(purchase)) {
                complain("Error purchasing. Authenticity verification failed.");
                setWaitScreen(false);
                return;
            }

            Log.d(TAG, "Purchase successful.");

            if (purchase.getSku().equals(SKU_GAS)) {
                // bought 1/4 tank of gas. So consume it.
                Log.d(TAG, "Purchase is gas. Starting gas consumption.");
                try {
                    mHelper.consumeAsync(purchase, mConsumeFinishedListener);
                } catch (IabAsyncInProgressException e) {
                    complain("Error consuming gas. Another async operation in progress.");
                    setWaitScreen(false);
                    return;
                }
            }
            else if (purchase.getSku().equals(SKU_PREMIUM)) {
                // bought the premium upgrade!
                Log.d(TAG, "Purchase is premium upgrade. Congratulating user.");
                alert("Thank you for upgrading to premium!");
                mIsPremium = true;
                updateUi();
                setWaitScreen(false);
            }
            else if (purchase.getSku().equals(SKU_INFINITE_GAS_MONTHLY)
                    || purchase.getSku().equals(SKU_INFINITE_GAS_YEARLY)) {
                // bought the infinite gas subscription
                Log.d(TAG, "Infinite gas subscription purchased.");
                alert("Thank you for subscribing to infinite gas!");
                mSubscribedToInfiniteGas = true;
                mAutoRenewEnabled = purchase.isAutoRenewing();
                mInfiniteGasSku = purchase.getSku();
                mTank = TANK_MAX;
                updateUi();
                setWaitScreen(false);
            }
        }
    };
