谷歌地图 v2 '错误膨胀类片段'

【问题标题】：Googlemaps v2 'Error inflaing class fragment"谷歌地图 v2 '错误膨胀类片段'
【发布时间】：2014-05-02 11:19:21
【问题描述】：

即使是打开一个简单的地图应用程序（无论是在 AVD 虚拟设备上还是在真正的 Android 手机上），我都遇到了真正的麻烦。使用 Eclipse/ADT 最新安装。

代码或多或少直接来自 GoogleMaps v2 的一本书章节（Wei-Meng Lee / Wrox 的“Android 应用程序开发手册”）。几周前 SSD 发生故障之前，我曾短暂运行过类似的代码。我没有修改书中的代码 - 下载/导入等。其他简单的 helloworld 和其他应用程序在 AVD 等上运行良好。

我有：

  • 添加了 google-play-services-lib
  • 获得了我的 GoogleMapsv2 API 密钥 - 保持包名称不变
  • 在这里和其他地方浏览了大量文章/问题，并比较了代码/检查了错误。

似乎没有任何帮助。在经历了 4 周的挫折之后，我现在请求帮助（如果这是一个简单的错误，可能会得到宽恕！）

我的清单文件内容如下：

}

我真的认为在在这里寻求帮助之前我已经尝试了所有方法。 （我曾经在 1980 年代初手写 Z80 汇编代码并将其手动转换为十六进制 - 与此相比，这太简单了......）

非常感谢你们的帮助！

  • 授予访问网络状态权限，然后检查并告诉我

标签： android eclipse google-maps fragment


【解决方案1】：

05-02 07:33:32.377: E/AndroidRuntime(1058): 由: java.lang.SecurityException：地图 API 需要额外的 在 AndroidManifest.xml 中设置以下权限以确保 正确行为：05-02 07:33:32.377：E/AndroidRuntime(1058)：

你不见了

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

在清单文件中

你有

 android:minSdkVersion="19"

你需要改变这个

 public class MainActivity extends FragmentActivity {

到 公共类 MainActivity 扩展 Activity {

你需要使用 MapFragment

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

也需要改变

 map = ((MapFragment) getFragmentManager()
        .findFragmentById(R.id.map)).getMap();

你也不需要

<permission
android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="net.learn2develop.googlemaps.permission.MAPS_RECEIVE" />

【讨论】：

  • 你确定@raghunandan
  • @sakir developers.google.com/maps/documentation/android/…。您可以检查文档，如果有错误请纠正我
  • 他已经被声明为“class="com.google.android.gms.maps.SupportMapFragment"
  • @sakir 应该是MapFragment。请再次检查文档。 MapFragment 用于 api 级别 12 及以上。 op有SupportMapFragmentclass="com.google.android.gms.maps.SupportMapFragment
  • 哎呀。在问题末尾添加了我的错误日志。之前尝试过 MapFragment，但如果我做得不对，会再试一次。让我感到困惑的是，我之前有代码工作过——也许是针对不同的 API 目标——它有那么大的不同吗？？ 8 小时打字后，我会先得到一些空气！再次感谢
