基本谷歌地圖Android版，2個小錯誤的權限

尊敬的社區，我正在學習在ANDROID谷歌地圖的整合和明白了很多事情，有權限，以及使用最新的GoogleApiAvailability但仍面臨2我無法解決的錯誤。我得到Cannot Resolve Method isUserRecoverableError(int) AND non-static method getErrorDialog cannot be referenced from a static context in the end of code在public boolean ServicesOK()方法。以下是Java代碼：（如果需要其他任何東西，請讓我知道，這樣我可以適當採用Android谷歌地圖的概念:)引導）來自GooglePlayServicesUtil不是來自GoogleApiAvailability基本谷歌地圖Android版，2個小錯誤的權限

isUserRecoverableError方法。但正如您在文檔中看到的，此方法已被棄用，您現在應該使用GoogleApiAvailability.getInstance().isUserResolvableError()而不是

並針對第二個錯誤嘗試訪問getErrorDialog，但這不是一種靜態方法。相反，你應該做GoogleApiAvailability.getInstance().getErrorDialog。

.getInstance（）對我來說就像一個魅力。非常感謝您清除我的概念，先生:) –
