我在正确的地方有API密钥，但我得到了上述错误。我已经清理了我的项目并重新安装。下面是我的android清单。我得到了一个“错误膨胀类片段造成的：android.view.InflationException:API key not found ... check that ^（above）.”有人知道为什么或者也遇到过这个问题吗？其他堆栈溢出问题没有帮助，因为我的在正确的位置：（

Also my fragment_map.xml where error happening (at inflating fragment)...

<fragment
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name="com.google.android.gms.maps.SupportMapFragment" />

...my Map.xml...
