大家好我正在开发一个应用程序，它在其中一个活动中显示地图和文本视图。但是当我运行 activity 应用程序停止运行ning 并抛出此消息时：

我在清单中声明了密钥，我也尝试用新密钥更改 api，但我得到了同样的错误。

我觉得这行很有趣：

Check that <meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/> is in the <application> element of AndroidManifest.xml

这是我的清单：

我尝试将我之前引用的那行与 api 放在一起，但仍然无法正常工作。我在互联网上看到了很多，但是 none 给出的解决方案可以解决这个问题。我希望你能找到我做错了什么。提前致谢

Answer 1

您需要添加以下行：

<meta-data android:name="com.google.android.geo.API_KEY" android:value="your API key"/>

在 <application> 和 </application> 标签之间，如错误所述。当然，您需要将 "your API key" 替换为 api 密钥。如果您不知道 api 密钥，请检查 this

Answer 2

您似乎已将 API_KEY 替换为 android:name 属性中的实际 api 密钥，这是错误的。

所以，替换为：

   <meta-data
        android:name="com.google.android.geo.AIza*******************"
        android:value="AIza*****************"/>

有了这个：

   <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="AIza*****************"/>

API 键错误
