android - 在 com.projects.fragments.MapFragment.refetch(MapFragment.java:207)

Question

我在以下位置出现错误：

com.projects.fragments.MapFragment.onMapReady(MapFragment.java:200) 在 com.projects.fragments.MapFragment.onMapReady(MapFragment.java:200) 在 com.google.android.gms.maps.SupportMapFragment$zza$1.zza （未知来源）在 com.google.android.gms.maps.internal.zzo$zza.onTransact（未知来源）

发生在运行时这个Mapfragment类
