我已经尝试了教程在我的应用程序中实现一个谷歌地图。 http://www.androidhive.info/2013/ 08 / Android的工作与 - 谷歌 - 地图-V2 /
I've tried a tutorial to implement a Google Maps in my application. http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/
我会尝试的例子,但它崩溃在这个级别:的setContentView(R.layout.activity_main);
I would try the example, but it is crashing at this level : setContentView(R.layout.activity_main);
我正确地按照政党成员,而且通常没有API的关键问题。
I correctly follow the tuto, and normally there is no API Key problem.

您错过在你的清单文件中新的强制性元标记,它是写在logcat中。
You're missing a new mandatory meta-tag in your manifest file, it's written in the logcat.
添加下面一行在您的清单文件,在应用程序
部分:
Add the following line in your manifest file, in the application
section:
<meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
此外,还有在你的清单另外一个问题,你已经复制您的活动的元标记 com.google.android.maps.v2.API_KEY
,同时应在应用程序设置
部分也是如此。
Also, there's another issue in your manifest, you have copied the meta-tag com.google.android.maps.v2.API_KEY
in your activity, while it shall be set in the application
section as well.
