開始 - 我已經閱讀了50個不同的線程，但是如果我嘗試實現它們，它們都是過時的或者充滿了錯誤。 此外 - 這個應用程序是不是商業用途，但只爲我自己的實踐項目。如何使用最新版本將Google地圖添加到Android？
我也跟着上starndard指南：https://developers.google.com/maps/documentation/android/start
的主要區別是，我已經有這是工作的應用程序。非常簡單 - 起始頁有5個按鈕，它們啓動intent（不是片段）來獲取有關不同方面的信息。
我想要做的是添加一個「找到我們」 - 谷歌地圖按鈕。每當我嘗試一個解決方案（Stackoverflow線程和其他指南）應用程序崩潰，我甚至不會看到錯誤，因爲我的logcat填充了十億條消息，因爲手機已連接，但應用程序不再運行（因爲它墜毀）。

「我甚至沒有看到錯誤，因爲我的logcat填充了十億條消息，因爲手機已連接，但應用程序不再運行」 - 然後使用搜索字段搜索對應用程序的引用，比如搜索'danieboy'，這是不太可能在其他地方使用的。 – CommonsWare
