在应用内结算BroadcastReceiver内存泄漏

Question

我要打开一个带有ActivityResult的Activity，并在成功购买商品后关闭当前的活动，该活动保存着采购过程并将数据发送回去。但是Leak Canary遇到了关于BillingBroadcastReceiver的内存泄漏。我初始化了计费客户端Index startIndex = 1; Index endIndex = 3; var NewList=CountryList[startIndex..endIndex] ，然后释放OnCreate。

这是我在onDestroy中调用的init方法

OnCreate

billingClient = BillingClient.newBuilder(this).setListener(this).build(); billingClient.startConnection(new BillingClientStateListener() { @Override public void onBillingSetupFinished(int responseCode) { if (responseCode == BillingClient.BillingResponse.OK) { // The billing client is ready. You can query purchases here. loadProducts(); } else { // Error } } @Override public void onBillingServiceDisconnected() { // Try to restart the connection on the next request to Timber.d("Connection Error"); } }); 准备就绪时加载产品信息

billingClient

这是我的释放方法，它在private void loadProducts() { if (billingClient.isReady()) { List<String> skuList = new ArrayList<>(getViewModel().getSkuIdList()); SkuDetailsParams params = SkuDetailsParams.newBuilder().setSkusList(skuList).setType(BillingClient.SkuType.INAPP).build(); billingClient.querySkuDetailsAsync(params, new SkuDetailsResponseListener() { @Override public void onSkuDetailsResponse(int responseCode, List<SkuDetails> skuDetailsList) { if (responseCode == BillingClient.BillingResponse.OK) { Timber.d("SkuList --> %s", skuDetailsList.size()); } else { Timber.d("Can't querySkuDetailsAsync, responseCode: %s", responseCode); } } }); } else { Timber.d("Billing Client not Ready"); } } 中调用

OnDestroy

OnPurchaseUpdated我打了一个服务电话，并根据服务结果关闭此活动。

    if (billingClient != null && billingClient.isReady()) {
        billingClient.endConnection();
        billingClient = null;
    }

我正在使用最新的库进行应用内购买

public void onPurchasesUpdated(int responseCode, @Nullable List<Purchase> purchases) {

    if (responseCode == BillingClient.BillingResponse.OK && purchases != null) { 
        for (Purchase purchase : purchases) {
            billingClient.consumeAsync(purchase.getPurchaseToken(), new ConsumeResponseListener() {
                @Override
                public void onConsumeResponse(int responseCode, String purchaseToken) {
                    if (responseCode == BillingClient.BillingResponse.OK && purchaseToken != null) {
                        Timber.d("onConsumeResponse --> %s", purchaseToken);
                        getViewModel().informPurchase(necessary data);
                    }
                }
            });
        }
    } else if (responseCode == BillingClient.BillingResponse.USER_CANCELED) {
        // Handle an error caused by a user canceling the purchase flow.
        Timber.d("Billing Cancelled");

    } else {
        Timber.d("An Error Occured");
    }
}

成功购买商品并关闭近期活动后，Leak Canary向我显示此错误。如何避免这种内存泄漏？

Answer 1

在if if (ValidateUser(Login1.UserName, Login1.Password)) { e.Authenticated = true; } else { e.Authenticated = false; } 准备就绪之前，活动已被销毁，因此 billingClient将为false，并且将永远不会调用billingClient.isReady，因此不会删除对Activity的引用（Activity是BillingClient的侦听器），并且会泄漏。 >

要解决，只需执行以下操作：

endConnection
