java - 启动后关闭放置选择器

Question

我正在 Android Studio 上使用 Googleplaces API 来根据位置显示感兴趣的地点。我正在使用 PlacePicker Inentbuilder 来完成此任务。

当应用程序运行时，地点选择器启动，然后立即关闭(大约 1-2 秒)。

• 我已经为 Android 应用程序生成了公共(public) API key ，并将其包含在应用 list 的元数据标记中。
• 我已在开发者控制台上启用了“Google Places API for android”API。
• 我已将最新的 Play 服务版本包含在 build.gradle 的依赖项中。

我已经在下面包含了我的代码和 Logcat。如果我需要添加任何其他内容，请告诉我。

Answer 1

请粘贴您的 logcat 和 manisfest 文件。

元数据标签可能应为 android:name="com.google.android.geo.API_KEY" 它应该在 <application> 范围内 list 中的标记。
