Question

我创建了一个新活动，即地图活动。我想我AndroidManofest.xml有问题。如果我使用地图活动创建新项目，我的手机将完美运行。如果我将它添加到我的项目，它有很多活动，它不起作用。我不知道为什么。

问题在于活动 AndroidManofest.xml

我检查了APU启用的所有内容

AndroidManofest.xml

Answer 1

更改您的Google地图set < string, cmp > genPerm ( const string& );。你不能在不同的项目中使用相同的API key Api

Answer 2

使用备用密钥：

 <meta-data
    android:name="com.google.android.backup.api_key"
    android:value="backupkey" />

Answer 3

转到Google Developer控制台，然后点击启用API和服务＆＃39;选项以及“信息中心”标签顶部的加号图标。然后是“谷歌地图Api”＃39;地图类别下的选项，选择该选项然后有＆＃39;管理＆＃39;选项将启用您的谷歌地图apis。

之后，您可以使用包名为项目创建地图密钥，然后在清单中使用它。

注意 - 使用密钥后，请重新安装应用程序以反映地图更改。

我的手机中没有显示地图活动，因为我有很多活动
