模拟GPS位置问题(Mock GPS location issue)

模拟GPS位置问题(Mock GPS location issue)

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：

I'm developing an APP that get user specified latitude,longitude, and altitude, then fake this GPS location on the phone, and show that I am at that location in google map. I have the required permission on manifest file and mocked location is enabled in developer settings.

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);

But looks like my GPS location is not changed at all on google map, what is the problem?

Update: I just installed an app called "fake GPS location" on my phone and that app works fine, but I still don't know what's wrong with my code, but I think mine is a formal way to achieve this.

Update #2: Although some of similar applications can run on my phone, but I found some exceptions, http://www.cowlumbus.nl/forum/MockGpsProvider.zip, this app is not working on my phone. can someone help me with this issue? millions of thanks! I'm not getting any error message when setting the location each time.

Update#3 : I noticed that this app is fairly old, so it does not run on 4.1. if so, how to do the same thing in the new version? my phone is samsung galaxy s3, hope it helps.

Update#4: for your info, the code from app in my update#2 is:

最满意答案

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。

Problem solved: I added the following code to set my current location and it can successfully show up in google map application.

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);

Conclusion: If you want to use mock location service in the new version of android, you have to set every attribute by yourself.
