Android:使用 api 谷歌地图崩溃启动应用程序

Question

我正在关注 https://developers.google.com/maps/documentation/android/start#installing_the_google_maps_android_v2_api学习使用 Google Map API。

这是我的 list :

我下载了 google play 服务并将其添加到我的工作区，但是当我尝试在手机中启动应用程序时，它崩溃了:

05-04 20:11:24.441: E/AndroidRuntime(11190): FATAL EXCEPTION: main 05-04 20:11:24.441: E/AndroidRuntime(11190): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.dude.uniplaces/com.dude.uniplaces.Index}: android.view.InflateException: Binary XML file line #19: Error inflating class fragment

编辑:
正如你所见，我修改了我的 index.xml，然后我以正确的方式添加(思考)谷歌库，但我仍然崩溃!

解决方案:

我解决了添加 import android.support.v4.app.FragmentActivity;
和 chancing 使用 FragmentActivity 扩展 Activity

Answer 1

右键单击项目并选择 Android 工具 -> 添加支持库 ...

并改变这个

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

对此

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

并且只是为了确认您已正确包含谷歌播放服务，右键单击项目并选择属性。在左侧选项卡中选择 Android。在右 Pane 的底部，您应该看到一个带有标签库的框架。如果正确添加了 google play，它将显示为绿色复选标记。还要确保在工作区中打开了 google play 项目。
