Android-> android.view.InflateException: Binary XML file line #2: Error inflating class fragment

Question

我已经尝试了类似问题中给出的所有解决方案，但仍然无法消除使用地图时膨胀类片段的错误。事实上，我的代码与类似问题的解决方案之一中给出的代码完全相同，但代码仍然无法运行。

Answer 1

您应该尝试使用SupportMapFragment 而不是MapFragment。

另外，请确保您的 build.gradle 具有
com.google.android.gms:play-services-maps:8.3.0

---

编辑
尝试使用

android:name="com.google.android.gms.maps.SupportMapFragment"

而不是

class="com.google.android.gms.maps.SupportMapFragment"

Answer 2

我花时间完整阅读了 logcat 错误日志，发现它告诉我将其添加到我的清单文件中 -->>

  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

它就像一个魅力......我正在寻找一天的解决方案......但我所要做的就是完整阅读错误日志......
