我已经建立了一个简单的应用程序,从这里获得位置(这里的开发者支持给予了一些帮助),问题是
answered here
此代码在我的手机上运行良好,可以在我的日志中每分钟生成一次地理位置。
我现在正试图在我的目标平板电脑上运行此代码。平板电脑很旧(运行Android5.1),没有GPS,也没有SIM卡或电话连接。唯一可能的定位方法是使用wifi。我已经在平板电脑上测试了here测试应用程序,它根据wifi连接找到了一个很好的近似位置——这是我试图复制的。
当我试图用GPS定位方法或GPS网络或网络初始化PositionManager时,我得到了相同的错误
对于这些行:
PositioningManager pm = PositioningManager.getInstance();
PositioningManager.LocationStatus ls = pm.getLocationStatus(PositioningManager.LocationMethod.GPS);
Log.i("Position", "Setting up positioning");
if (ls == PositioningManager.LocationStatus.AVAILABLE) {
Log.i("Position", "Positioning is available");
} else {
Log.w("Position", "Positioning not available right now: " + ls.toString());
}
boolean ret = pm.start(PositioningManager.LocationMethod.GPS);
Log.i("Position", "Positioning start returns " + ret);
我得到这些日志:

每一分钟我都会检查位置
GeoPosition pos = PositioningManager.getInstance().getPosition();
它是空的。如果我将locationMethod设置为空,我不会得到异常,但仍然不会得到任何地理位置。
如何在他们的测试应用程序中管理它,以便仅从wifi获取位置?
