android 获取手机信息（device ip，os version etc.）
好久没有写东西了，今天在做pv log记录，需要记录机器的os version, 机器的wifi IP address, 当前时间等等。 调查了一下，分享分享：
package com.osip;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import android.app.Activity;
import android.net.wifi.WifiInfo;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.widget.TextView;
public class Osip extends Activity {
private TextView osVersion, clientIp, date;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
osVersion = (TextView) findViewById(R.id.os_version);
clientIp = (TextView) findViewById(R.id.client_ip);
date = (TextView) findViewById(R.id.date);
String format = "yyyyMMdd.HHmmss.SSSZ";// 带毫秒和时区的时间格式
String version = getosVersion();
String ip = getIp();
String cDate = getDate(new Date(), format);
osVersion.setText(version);
clientIp.setText(ip);
date.setText(cDate.substring(0, 22));
}
private String getDate(Date date, String format) {
DateFormat dateFormat = new SimpleDateFormat(format);
return dateFormat.format(date);
}
// 取得device的IP address
private String getIp() {
WifiManager wifiManager = (WifiManager) getSystemService(WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
int ipAddress = wifiInfo.getIpAddress();
// 格式化IP address，例如：格式化前：1828825280，格式化后：192.168.1.109
String ip = String.format("%d.%d.%d.%d",
(ipAddress & 0xff),
(ipAddress >> 8 & 0xff),
(ipAddress >> 16 & 0xff),
(ipAddress >> 24 & 0xff));
return ip;
}
//获取device的os version
private String getosVersion() {
String version = android.os.Build.VERSION.RELEASE;
return version;
}
}
