我刚刚下载了 Indoor Atlas SDK 并尝试运行。我设法修复了各种小错误，但现在卡住了。该应用程序安装（通过模拟器和 Galaxy 标签），但都给了我同样的错误：

E/AndroidRuntime﹕ FATAL EXCEPTION: IdaSensorReadingManager
    Process: xxxx.indooratlas, PID: 1632
    java.lang.NullPointerException: Attempt to invoke virtual method 'int android.hardware.Sensor.getType()' on a null object reference
            at com.indooratlas._internal.ai.a(Unknown Source)
            at com.indooratlas._internal.ai.b(Unknown Source)
            at com.indooratlas._internal.ai$a.handleMessage(Unknown Source)

            at android.os.Looper.loop(Looper.java:135)
            at android.os.HandlerThread.run(HandlerThread.java:61)

这个标准的 Android 错误或 Indoor Atlas 是特定的吗？

SDK 版本：indooratlas-android-sdk-release-1.3.1-108 在 Android 4.4 和 5.0 上测试

您目前（版本 1.3.1）无法使用模拟器运行 IndoorAtlas 的 Android SDK。IndoorAtlas 的技术主要基于磁定位（即使用磁场传感器并融合其他传感器）。您也许可以运行 SDK，但除非您设法在模拟器中模拟这些传感器，否则您不会走得太远，因为您不会获得任何位置。查看 IndoorAtlas 服务的主要功能：https ://www.indooratlas.com/features 。有一些模拟传感器的项目，例如：https ://code.google.com/p/android-sensor-emulation/- 但如果可能，我建议使用真实设备。请注意，为了进行完整的定位测试，您还需要创建您所在位置的磁图（除非附近已经有地图的公共位置），请参阅开发者网站了解如何完成它：https://developer .indooratlas.com/dashboard（收集数据）。

IndoorAtlas for Android 不在模拟器上运行。它至少需要 Android Gingerbread 版本。该设备还需要陀螺仪和磁力计。首先检查一下。
