android - 当我将 Google Map Api v2 用于 map 时，我无法添加 Google Play 服务库

Question

我想使用 Google Map v2 在 map 中显示当前位置。我创建 sha key 并生成 API key ，还与 androidmanifest.xml 集成。我下载以下链接的示例:

http://wptrafficanalyzer.in/blog/showing-current-location-in-google-maps-using-api-v2-with-supportmapfragment/

我还提供了互联网权限和其他但在我的日志猫中显示以下错误。

现在我可以做什么来显示 map ？

Answer 1

map Activity

public class MainActivity extends FragmentActivity {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }



}

activity_main

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>

list 文件

            </intent-filter>
        </activity>

        <meta-data

            android:value="YourKey" />
    </application>`enter code here`

</manifest>

打开sdk manager，在extras下下载google play service，会得到两个库google-play-services_lib.jar和google-play-services.jar。您可以在 extras 的 google play service 下找到这些库。您必须复制这两个库并粘贴到应用程序的 lib 文件夹下，并将这些库添加到 java 构建路径下。
