获得手机相关信息的实现方法

      本文介绍了如何通过android提供的service来获取手机的相关信息。比如:手机当前网络连接状态、运行内存使用情况、cpu型号、sd卡、ip等相关信息。
一、设置访问权限
在AndroidManifest.xml 文件中加入访问权限
  

 <!-- 连接互联网Internet权限 -->
    <uses-permission android:name="android.permission.INTERNET" />
    <!-- GPS -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <!-- 获取ip权限 -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <!-- SD卡存储信息 -->
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <!-- 网络是否连接 -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <!-- 手机imei -->
    <uses-permission android:name="android.permission.READ_PHONE_STATE" />

 
二、主页面layout布局,采用RelativeLayout方式布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="top"
    tools:context=".MainActivity" >
