我目前正在SupportMapFragment使用google-play-services库r3 实现我自己的子类.

我得到一个NullPointerException在图书馆的内部类中的一个,当我尝试我的片段添加到Activity或ViewPager.这是相关的堆栈跟踪:

java.lang.NullPointerException
    at maps.y.p.onResume(Unknown Source)
    at com.google.android.gms.maps.internal.IMapFragmentDelegate$Stub.onTransact(IMapFragmentDelegate.java:115)
    at android.os.Binder.transact(Binder.java:310)
    at com.google.android.gms.maps.internal.IMapFragmentDelegate$a$a.onResume(Unknown Source)
    at com.google.android.gms.maps.SupportMapFragment$a.onResume(Unknown Source)
    at com.google.android.gms.internal.c$1.a(Unknown Source)
    at com.google.android.gms.internal.c.a(Unknown Source)
    at com.google.android.gms.internal.c.onResume(Unknown Source)
    at com.google.android.gms.maps.SupportMapFragment.onResume(Unknown Source)
    at android.support.v4.app.Fragment.performResume(Fragment.java:1503)
    at android.support.v4.app.FragmentManagerImpl.moveToState(FragmentManager.java:947)
    at android.support.v4.app.FragmentManagerImpl.performPendingDeferredStart(FragmentManager.java:807)
    at android.support.v4.app.FragmentManagerImpl.startPendingDeferredFragments(FragmentManager.java:1112)
    at android.support.v4.app.FragmentManagerImpl.execPendingActions(FragmentManager.java:1461)
    at android.support.v4.app.FragmentManagerImpl.executePendingTransactions(FragmentManager.java:461)

显然,此时内部地图为空.

有没有人遇到过这个问题而且有解决方案？
