谷歌地图 API v2。安卓

Question

我正在尝试开发一个 android 应用程序，它可以在 google 地图上显示我的当前位置，但我在模拟器上显示地图时遇到了困难。从昨天开始我一直在处理这个问题，我尝试通过浏览类似的线程来寻找解决方案，但我无法弄清楚我的代码有什么问题。

这是我的日志：

这是我的 activity_main.xml

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

在 Eclipse IDE 中创建 AVD 时使用 google api 19 版本的模拟器。

地图仅在 google api 模拟器中可用。如果问题仍然存在，请将模拟器的 SDK 更新到最新版本，然后重试。

Answer 2

是的，您也可以在模拟器中获取地图。要实现这一点，请按照我在另一篇文章中回答的逐步过程this 进行操作

Answer 3

在您的清单中： 元数据 必须在应用程序块之外 你必须添加：

<meta-data android:name="com.google.android.gms.version>     android:value="@integer/google_play_services_version"/>
