Android 计费 v3 - BillingClientImpl.java 中的 NullPointerException :668

Question

我对 Google Play Billing Library v3 有异议。 我在 onDestroy Activity 方法中释放计费客户端。

有人遇到过这个问题吗？

Fatal Exception: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String android.content.Context.getPackageName()' on a null object reference

计费客户端连接调用代码:

private com.android.billingclient.api.BillingClient billingClient;

public AppBillingManager(Context context) {
    billingClient = new BillingClient.Builder(context)
            .setListener(this)
            .build();
}

public void doConnect(final Runnable postConnection) {
    billingClient.startConnection(new BillingClientStateListener() {
        @Override
        public void onBillingSetupFinished(int resultCode) {
            isConnected = BillingClient.BillingResponse.OK == resultCode;
            notifyConnectivityState();
            if (isConnected) {
                postConnection.run();
            } else {
                listener.onConnectedToBillingService(resultCode);
            }
        }

        @Override
        public void onBillingServiceDisconnected() {
            isConnected = false;
            listener.onDisconnectedBillingService();
        }
    });
}

public void release() {
    this.billingClient.endConnection();
}

Google 最近发布了新版本的计费库。看看这个。这应该是固定的。 https://android-developers.googleblog.com/2017/09/google-play-billing-library-10-released.html
