我正在开发一个具有活动MapReminderActivity的应用程序，负责在片段id映射中显示地图，但是当渲染活动时，我得到的只是一个空白片段。我的Logcat声明了一些身份验证问题。我检查了Api键甚至重新生成它并尝试使用那个，但仍然是空白片段。
MapReminderActivity：

答案 0 :(得分：0)
尝试从manifest.xml文件中删除以下行
<uses-permission android:name="com.afifagroup.gps.permission.MAPS_RECIEVE" />
并检查你的layout.xml应该是：
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
