我試圖將Google Analytics（分析）實現到我的Android應用程序中，但我遵循示例，它給了我createAppView無法解析或不是字段。我認爲這是因爲它沒有定義 - 但不應該在谷歌的例子中定義它？我不希望他們犯這樣的錯誤，我有一種感覺，我在我的最後做錯了事。createAppView無法解析或不是字段
要看到我使用的是有在「完整的例子，」在這裏看一下例子：

問題是MapBuilder甚至沒有擺在首位存在！即使我已經使用了「import com.google.analytics.tracking.android。*;'，似乎Google的文檔已經過時了v3分析庫，MapBuilder無法解析。 –
感謝你們倆 –
