Android Place Picker在启动后立即关闭 [英] Android Place Picker closes immediately after launch
问题描述
我正在开发一个Android应用程序作为项目的一部分，并且正在使用Google places API根据位置显示感兴趣的地方.我正在使用PlacePicker Inentbuilder来完成此操作.
I am developing an android application as part of a project, and am using Google places API to display places of interest based on location. I am using the PlacePicker Inentbuilder to accomplish this.
但是，运行该应用程序时，地点选择器会启动，然后立即关闭(大约1-2秒).
However, when the app is run, the place picker launches and then closes immediately (about 1-2 seconds).
我已经实施了以下建议(从其他答案中得到的建议):
I have already implemented the below suggestions (that I got from other answers):
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meta-data标签中.
I have generated the public API key for android applications, and am including this in the meta-data tag in the app manifest.
我已在开发人员控制台上启用了适用于Android的Google Places API" API.
I have enabled the "Google Places API for android" API on the developers console.
我在build.gradle的依赖项中包括了最新的Play服务版本.
I have included the latest play services version in dependencies in build.gradle.
我在下面包含了我的代码和logcat.让我知道是否需要添加其他内容.
I have included my code and the logcat below. Do let me know if I need to include anything else.

推荐答案
Francois Wouts的解决方案有助于回答这一问题.谢谢弗朗索瓦...
Francois Wouts' solutions helped answer this. Thank you Francois...
我使用关键字"Places"搜索了日志，发现Places API确实抛出了异常.期望Manifest.xml中<application>标记内的com.google.android.geo.API_KEY.
I searched the logs with keyword 'Places' and found that Places API was indeed throwing an exception. It expected the com.google.android.geo.API_KEY within the <application> tags in the Manifest.xml.
我已将<activity>标记中的内容更改为com.google.android.geo.API_KEY，而不是<application>标记中的内容.
I had changed to com.google.android.geo.API_KEY in the <activity> tag and not the one in the <application> tag.
现在更改为com.google.android.geo.API_KEY，并从<activity>标记中删除了相同的行，并使其起作用.感觉像个白痴，因为我自己没有解决这个问题.
Now changed to com.google.android.geo.API_KEY and removed the same lines from <activity> tag, and got it working. Feel like an idiot for not working this out by myself..
元数据标签应显示为
android:name="com.google.android.geo.API_KEY"
它应该在清单的<application>标记内.
The meta-data tag should read
android:name="com.google.android.geo.API_KEY"
It should be within the<application>tag in the Manifest.
