模拟GPS位置问题
我正在开发一个获取用户指定的纬度，经度和海拔高度的APP，然后在手机上伪造这个GPS位置，并显示我在谷歌地图中的那个位置。 我对清单文件具有所需权限，并且在开发人员设置中启用了模拟位置。
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); //lm.clearTestProviderEnabled(mocLocationProvider); lm.addTestProvider(mocLocationProvider, false, false, false, false, false, false, false, 0, 10); lm.setTestProviderEnabled(mocLocationProvider, true); mockLocation = new Location(mocLocationProvider); // a string mockLocation.setLatitude(Integer.parseInt(latitude.getText().toString())); // double mockLocation.setLongitude(Integer.parseInt(longitude.getText().toString())); mockLocation.setAltitude(Integer.parseInt(altitude.getText().toString())); mockLocation.setTime(System.currentTimeMillis()); lm.setTestProviderLocation( mocLocationProvider, mockLocation); 但看起来我的GPS位置在谷歌地图上根本没有改变，有什么问题？
更新：我刚刚在我的手机上安装了一个名为“伪GPS位置”的应用程序，该应用程序工作正常，但我仍然不知道我的代码有什么问题，但我认为我的正式方法是实现这一点。
更新＃2：虽然一些类似的应用程序可以在我的手机上运行，但我发现了一些例外， http：//www.cowlumbus.nl/forum/MockGpsProvider.zip ，这个应用程序无法在我的手机上运行。 有人可以帮我解决这个问题吗？ 数百万的谢谢！ 每次设置位置时我都没有收到任何错误消息。
更新＃3：我注意到这个应用程序相当陈旧，所以它不能在4.1上运行。 如果是这样，如何在新版本中做同样的事情？ 我的手机是三星galaxy s3，希望它有所帮助。
更新＃4：对于您的信息，我的更新＃2中的应用程序代码是：

问题解决了：我添加了以下代码来设置我当前的位置，它可以成功显示在谷歌地图应用程序中。
location.setLatitude(latitude); location.setLongitude(longitude); location.setBearing(bearing); location.setSpeed(speed); location.setAltitude(altitude); location.setTime(new Date().getTime()); location.setProvider(LocationManager.GPS_PROVIDER); location.setAccuracy(1);
结论：如果你想在新版本的android中使用模拟位置服务，你必须自己设置每个属性。
