【问题描述】:
在Criteria 类中,有两个常量ACCURACY_HIGH 和ACCURACY_FINE,显然用于要求LocationManager 返回更高精度的位置更新。以下是documentation 对每个常量的说明:
public static final int ACCURACY_FINE(在 API 级别 1 中添加)
A constant indicating a finer location accuracy requirement Constant Value: 1 (0x00000001)public static final int ACCURACY_HIGH(在 API 级别 9 中添加)
a constant indicating a high accuracy requirement - may be used for horizontal, altitude, speed or bearing accuracy. For horizontal and vertical position this corresponds roughly to an accuracy of less than 100 meters. Constant Value: 3 (0x00000003)
有谁知道这两个常数中的哪一个提供(即要求)最高水平的准确度?
