我是Android应用程序的新手，正在我的Android应用程序上显示Google地图。我正在使用Min SDK：8＆amp;目标SDK：18。我搜索所有可能的解决方案，但没有用。我得到了同样的致命错误，“无法找到主要”。我在我的工作空间中导入了google-play-services lib项目。
我发布的代码供参考。

应用错误
不幸的是app停止了，我试图清除我的应用程序管理器中的缓存和数据。
我想知道我哪里出错了，为什么会出现这个错误。如果有人能在这种情况下帮助我，那将是很棒的。
答案 0 :(得分：1)
第一个问题出在您的清单文件中。你必须将下一段代码放在应用程序标签中（因为现在你已将它放在外面）。
<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyBE3g9WqWo5iiBOuuc03Osu7jEbHOF_8IQ" />
这是我看到的第一件事。尝试它是否有效。如果我们不检查整个代码。
PD：永远不要发布您的API密钥。
