我使用下面的代码来设置模拟位置。不需要位置许可.
然而,该代码在Android设备上与最新的Google Play服务版本不一致,该版本利用了最新的Google Play服务。FusedLocationProviderClient
. 有时能如愿以偿地工作,有时位置一直来回跳动,有时根本不工作。我还经常收到崩溃的错误信息 java.lang.IllegalArgumentException: Provider “gps” already exists
. 基本上,这是一个糟糕的代码,我想在我的应用程序中删除它。
我需要的是一个完整的解决方案,能够成功地伪造设备的位置(不需要位置权限),就像这样。假的GPS应用. 我希望用Java重新创建那个应用程序。我在网上还没有找到任何能在2020年5月前完全运行的东西。我很感谢你在这方面的帮助。
void setMockLocation() {
LocationManager locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.addTestProvider(LocationManager.GPS_PROVIDER, false, false,
false, false, true, true, true, 0, 5);
locationManager.setTestProviderEnabled(LocationManager.GPS_PROVIDER, true);
Location mockLocation = new Location(LocationManager.GPS_PROVIDER);
mockLocation.setLatitude(-33.852); // Sydney
mockLocation.setLongitude(151.211);
mockLocation.setAltitude(10);
mockLocation.setAccuracy(5);
mockLocation.setTime(System.currentTimeMillis());
mockLocation.setElapsedRealtimeNanos(System.nanoTime());
locationManager.setTestProviderLocation(LocationManager.GPS_PROVIDER, mockLocation);
}
我在Github上看了一下,我使用了服务构建的 此处.下面的代码对我有用。
