Question

我正在尝试在我的应用程序中实施Google Maps api v2。

我在此处关注Google的文档link

但有时我的应用程序崩溃很遗憾，没有向我显示地图。

然后我按照本教程实施Google地图link

但我的问题仍然没有改变。请一些人建议我如何解决我的问题。我在此处附加了错误日志。 enter image description here

修改： - 我的错误日志 link

Answer 1

添加xml片段

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

也在

<meta-data
android:name="com.google.android.gms.version"
android:value="4.1.32" />

尝试使用value =“4132500”

Answer 2

如果您的xml文件是这样的，

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

在类文件而不是片段活动中使用SupportFragmentActivity

XML： -

   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".MainActivity" >


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