Как это можно решить?

Answer 1

Изменить эти строки:

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
     .findFragmentById(R.id.map); 
mapFragment.getMapAsync(this); 

для этого строки кода:

MapFragment map = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)); 
    map.getMapAsync(this); 

Answer 2

Я думаю вместе с ответом W.Kurek, это может понадобиться:

Вы можете либо изменить ваш SupportMapFragment to MapFragment, как предложено W.Kurek ИЛИ, внесите изменения в свой XML-макет, как показано ниже, и продолжайте использовать тот же Ja va в вашей деятельности.

<fragment 
      android:id="@+id/map" 
      class="com.google.android.gms.maps.SupportMapFragment" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" /> 

Обратите внимание, что я использовал class="com.google.android.gms.maps.SupportMapFragment" вместо android:name="com.google.android.gms.maps.SupportMapFragment"
