Android 地点选择器启动后立即关闭

我正在开发一个android应用程序作为项目的一部分，并使用Google地方API来根据位置显示感兴趣的地方。我正在使用 PlacePicker Inentbuilder 来完成此任务。

但是，当应用程序运行时，地点选择器会启动，然后立即关闭（大约 1-2 秒）。

我已经实施了以下建议（我从其他答案中得到的）：

我已经为 Android 应用程序生成了公共 API 密钥，并将其包含在应用程序清单的元数据标记中。

我已在开发人员控制台上启用了“Google Places API for android”API。

我已将最新的播放服务版本包含在 build.gradle 的依赖项中。

我已经包含了我的代码和下面的 logcat。如果我需要添加其他内容，请告诉我。

Francois Wouts 的解决方案帮助回答了这个问题。谢谢弗朗索瓦...

我用关键字“Places”搜索日志，发现 Places API 确实抛出了异常。它预计com.google.android.geo.API_KEY内<application>Manifest.xml 中的标签。

我已经改为com.google.android.geo.API_KEY in the <activity>标签而不是<application> tag.

现在改为com.google.android.geo.API_KEY并从中删除了相同的行<activity>标签，并让它工作。感觉自己像个白痴，不自己解决这个问题。

元数据标签应读取android:name="com.google.android.geo.API_KEY"
它应该在<application>清单中的标签。
