java - IabHelper(类)Dispose(方法)未处理的异常

Question

我正在尝试在我最新的 android 项目中实现应用内购买。为此，我正在关注此 guide .一切都很顺利，直到我使用 dispose 方法关闭与 Play 商店的所有通信。我得到的是以下错误:

Error:(101, 45) error: unreported exception IabAsyncInProgressException; must be caught or declared to be thrown

在下面的代码段中:

@Override
    public void onDestroy() {
        super.onDestroy();
        //Always unbind the with the store connection, otherwise performance degradation of the device may follow.
        if (mHelper != null) mHelper.dispose();
        mHelper = null;
    }

深入了解 IabHelper 类 (Java) 后，我找到了 dispose 方法。方法代码如下:

    /**
     * Dispose of object, releasing resources. It's very important to call this
     * method when you are done with this object. It will release any resources
     * used by it such as service connections. Naturally, once the object is
     * disposed of, it can't be used again.
     */
    public void dispose() throws IabAsyncInProgressException {
        synchronized (mAsyncInProgressLock) {
            if (mAsyncInProgress) {
                throw new IabAsyncInProgressException("Can't dispose because an async operation " +
                    "(" + mAsyncOperation + ") is in progress.");
            }
        }
        logDebug("Disposing.");
        mSetupDone = false;
        if (mServiceConn != null) {
            logDebug("Unbinding from service.");
            if (mContext != null) mContext.unbindService(mServiceConn);
        }
        mDisposed = true;
        mContext = null;
        mServiceConn = null;
        mService = null;
        mPurchaseListener = null;
    }

我应该怎么做才能解决这个错误？我知道我应该捕获和异常，但是我没有足够的信心在这个类中自己更改这个方法。

(感谢您的帮助)

Answer 1

经过更多研究后，我发现这个问题已经被提出并得到了回答。不幸的是，该问题仍被标记为未回答。这里有 link to the original question .

解决方法很简单:

1. 您可以从指南中获得的文件已过时，应改为从 github 下载.

2. 在 onDestroy 方法中，您应该改用以下代码:

   @Override
   public void onDestroy() {
      super.onDestroy();
      //Always unbind the connection with the store, otherwise performance degradation of the device may follow.
      if (mHelper != null) {
         mHelper.disposeWhenFinished();
         mHelper = null;
      }
   }
   

disposeWhenFinished 这是一个比 dispose 更优雅的解决方案。
