Google Play：从IInAppBillingService更新价格

Question

我创建了一个用于在商店中处理订阅的类。一开始，我从服务器收到订阅列表，其中包含价格代码正在运行，在大多数设备上都没有问题。但有些用户没有收回价格。这就像服务器没有响应。我已经研究了Google文档中的实现示例，但我无法理解代码中可能出现问题的位置。我的部分代码：

public class BillingActivity extends AppCompatActivity {

RelativeLayout imageLayout;
View payButton;
// WebView payWebView;
// TextView useCodeButton;

ProgressBar progress1;
ProgressBar progress2;
ProgressBar progress3;

IInAppBillingService inAppBillingService;

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_billing_subscription);
    price_1monthTextView = (TextView) findViewById(R.id.price_1monthTextView);
    relative_1month = (RelativeLayout) findViewById(R.id.relative_1month);
    relative_1month.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (MainActivity.myAccount == null) return;
            if (MainActivity.myAccount.getUniqid() == null) return;
            if (subscription1m != null) {
                try {
                    Log.d("my", "purchase..." + subscription1m.storeName);
                    purchaseProduct(subscription1m);
                } catch (Exception e) {
                    e.printStackTrace();
                    Log.d("my", "purchase error = " + e.toString());
                }
            }
        }
    });


    progress1 = (ProgressBar) findViewById(R.id.progress1);
    startGoogleBilling();
}


private void startGoogleBilling() {
    if (serviceConnection != null) {
        unbindService(serviceConnection);
    }

    progress1.setVisibility(View.VISIBLE);


    serviceConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            inAppBillingService = IInAppBillingService.Stub.asInterface(service);

            getSubscribtionsList();
        }

        @Override
