谷歌地图Android的API V2 - 样品code崩溃 [英] Google Maps Android API v2 - Sample Code crashes

问题描述

我想获得的样品code Android的谷歌地图Android的API V2'的工作。我得到建没有错误的项目。然而，当我尝试在我的Galaxy Nexus的（带USB连接到我的笔记本电脑）运行的应用程序，该应用程序立即崩溃。

I'm trying to get the sample code of Android 'Google Maps Android API v2' working. I get the project built without errors. However, when I try to run the app on my Galaxy Nexus (connected with usb to my laptop), the app crashes immediately.

• 在我填写在AndroidManifest.xml中
我自己的地图API密钥
• 在我建立针对安卓4.1.2

• I filled in my own Maps API Key at the AndroidManifest.xml
• I built against Android 4.1.2

这是记录：

没有任何人有一个提示如何解决这个或我可能是做错了？

Does anybody have a hint how to solve this or what I might be doing wrong?

推荐答案

按照垛板非常，非常小心：

Follow the crib sheet very, very carefully:

在特别的，我想你需要：

In particular, I think you need to:

• 导入为谷歌播放services_lib项目实际出处及链接它作为一个机器人库。
  • 请通过此项目 - >属性 - > Android的 - >库，添加 - >谷歌播放services_lib（你可以右键点击你的项目，并选择属性，然后选择Android的）。
  • 请不可以添加为通过Java构建路径为您的项目相关的项目，这并没有为我工作。
  • Import the actual source for the "google-play-services_lib" project and link it as an Android library.
    • Do this through Project -> Properties -> Android -> Library, Add -> google-play-services_lib (you can right click on your project and choose Properties, then select Android).
    • Do not add it as a dependent Project through the "Java Build Path" for your project, that didn't work for me.

    我发现这第二个步骤是必要的，因为我试图使用示例code击球时完全相同的错误，因为你。第一步是要避免的NoClassDefFoundError 在 com.google.android.gms.R $设置样式在我的现实项目。

    I found this second step was necessary as I was hitting the exact same error as you when trying to use the sample code. The first step was necessary to avoid a NoClassDefFoundError in com.google.android.gms.R$styleable in my real project.

    我还需要前样品code的工作做一个干净的构建，并从设备上删除应用程序（从早期的测试中尝试）。

    I also needed to do a Clean build and Uninstall the app from the device (from an earlier test attempt) before the sample code worked.
