The import com.google cannot be resolved
提问by Josh Boothe
I am trying to do a Map View in android (migrating from iOS). In the android SDK pannel I have google APIs (API 17) installed, which I was hoping would fix the problem. So in my source code I have:
我正在尝试在 android 中执行地图视图（从 iOS 迁移）。在 android SDK 面板中，我安装了 google API（API 17），我希望它可以解决问题。所以在我的源代码中，我有：
import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
And its giving me the error: The import com.google cannot be resolved. I have searched google for a result, but they havent worked (most of them were making sure the Google API is installed.
它给了我错误：The import com.google cannot be resolved. 我已经在谷歌上搜索了结果，但他们没有工作（他们中的大多数人都确保安装了谷歌 API。

You have to add the library to your project.
您必须将库添加到您的项目中。
You can find the .jar file in your sdk
sdk\add-ons\addon-google_apis-google-17\libs\maps.jar
您可以在 sdk 中找到 .jar 文件
sdk\add-ons\addon-google_apis-google-17\libs\maps.jar

You also need to set the build target (Project > Properties > Android) to be a build target that has the Google APIs in it, to use Maps V1.
您还需要将构建目标（项目 > 属性 > Android）设置为包含 Google API 的构建目标，以使用 Maps V1。
That being said, Raghunandan is correct -- you should be using Maps V2, as you can no longer get Maps V1 API keys. Note that Maps V2 does notrequire you to have a "Google APIs" build target.
话虽如此，Raghunandan 是正确的——您应该使用 Maps V2，因为您无法再获得 Maps V1 API 密钥。需要注意的是地图V2并没有要求你有一个“谷歌的API”构建目标。
