在AndroidManifest.xml文件中，只需声明ACCESS_FINE_LOCATION权限即可自动获取ACCESS_COARSE_LOCATION权限。示例如下：

在代码中使用时，可以检查ACCESS_FINE_LOCATION权限是否被授予来确定ACCESS_COARSE_LOCATION权限是否可用。示例如下：

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
    == PackageManager.PERMISSION_GRANTED) {
    // ACCESS_FINE_LOCATION permission is granted, ACCESS_COARSE_LOCATION is also available
} else {
    // ACCESS_FINE_LOCATION permission is not granted, request it (which also includes ACCESS_COARSE_LOCATION)
    ActivityCompat.requestPermissions(this,
        new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
        REQUEST_LOCATION_PERMISSION);
}
