我在Android Studio上使用Google Places API来根据位置显示感兴趣的地方。我正在使用PlacePicker Inentbuilder来实现这一目标。
当应用程序运行时,位置选择器启动然后立即关闭(大约1-2秒)。
我已将我的代码和Logcat包含在下面。如果我需要包含其他任何内容,请告诉我。
的Manifest.xml:

答案 0 :(得分:1)
请粘贴您的logcat和manisfest文件。
可能是元数据标记应该是android:name="com.google.android.geo.API_KEY"
它应该在Manifest中的<application>
标记内。
