Make sure you have declared the fragment in your layout. 确保已在布局中声明了片段。 Like following. 喜欢以下。
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>
Also that you have added Google Play services library in your project. 另外，您已在项目中添加了Google Play服务库。
Follow these instruction step by step : https://developers.google.com/maps/documentation/android/start 请按照以下说明进行操作： https : //developers.google.com/maps/documentation/android/start

I had the same problem and I did the mistake to only add one of the 2 following tags. 我遇到了同样的问题，但我犯了一个错误，只添加了以下两个标签之一。 Note that you are also missing one of these two 请注意，您也缺少这两个之一
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="<YOUR VALUE>"/>
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
The actual error is really misleading, as you might be thinking of some API level UI issue. 实际的错误确实会引起误解，因为您可能会想到一些API级别的UI问题。
