Android通过GPS或NetWork获取当前位置信息

刚完成一个需要通过GPS获取位置信息的项目（内网项目），所以根据LocationManager获取Providers会出现依旧能判断有网络连接，debug获取providers为[passive, gps, network, local_database]。
下面贴出解决代码：

onDestroy() {super.onDestroy();removeLocationUpdatesListener();}// 方法一/*private void getLocation() {// 需要检查权限,否则编译报错,想抽取成方法都不行,还是会报错。只能这样重复 code 了。if (Build.VERSION.SDK_INT >= 23&&

注意事项：

1. GPS获取位置信息需要在开阔地方才有GPS信号。
2.开启相对应的权限。
