Android 4.3 Android版Android API V2问题

时间:2014-01-14 18:18:23

标签: android google-maps

我是谷歌地图的新手。只需点击此链接http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/ 当我启动我的应用程序时,会出现以下错误:

Unfotunately Googlemapsv2 has stopped

我在stackoverflow上经历了很多帖子,但仍未解决问题所在。

activity_main.xml中

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

</RelativeLayout>

编辑: 当我在清单文件中进行以下更改时

<meta-data android:name="com.google.android.gms.version" android:value="AIzaSyBAjfcxZvbt_COHjy7igHZnLBfsO1cfoM8" />

请帮我找出解决方案。

5 个答案:

答案 0 :(得分:2)

正如你对@gokhan回答的评论,你应该做

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

但是,你还需要做

<meta-data
    android:name="com.google.android.maps.v2.API_KEY"
    android:value="@string/app_key" />

其中app_key是您的Key

我建议您在ids.xml文件夹中创建一个values文件,其内容如下:

<resources>
    <string name="app_id" translatable="false">1234567890</string>

可能您忘记添加google_api_key,您必须添加密钥才能使用此服务

你应该添加你的密钥AndroidManifest.xml

<application>

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="xxxxxxxxxx" />

</application>
像这样。

我希望这对你有帮助

我认为你需要下载谷歌播放服务r10甚至r12。那你就不需要了

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

为了更好地理解,请按照link

进行操作

答案 3 :(得分:0)

在我的清单文件中添加这两行之后就可以了。

对于eclipse,请添加:

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

    <meta-data android:name="com.google.android.maps.v2.API_KEY"
              android:value="Your KEY" />

如果您使用的是带有gradle0.7 +的Android Studio,请添加以下行:

<meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="Your Key" />
