获取版本号和版本名：

       PackageManager pm = context.getPackageManager();          PackageInfo pi = pm.getPackageInfo(context.getPackageName(), 0);          versionName = pi.versionName;          versioncode = pi.versionCode;

手机型号、系统版本号、sdk版本号

手机型号：android.os.Build.MODEL

sdk版本号：android.os.Build.VERSION.SDK_INT

android系统版本号：android.os.Build.VERSION.RELEASE

获取手机分辨率；宽、高

        WindowManager windowManager = getWindowManager();            Display display = windowManager.getDefaultDisplay();            int screenWidth = screenWidth = display.getWidth();            int screenHeight = screenHeight = display.getHeight();

//wifi情况下获取手机ip

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission>

       //获取wifi服务          WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);          //判断wifi是否开启          if (!wifiManager.isWifiEnabled()) {          wifiManager.setWifiEnabled(true);            }          WifiInfo wifiInfo = wifiManager.getConnectionInfo();               int ipAddress = wifiInfo.getIpAddress();            String ip = (ipAddress & 0xFF ) + "." +               ((ipAddress  >> 8 ) & 0xFF) + "." +               ((ipAddress  >> 16 ) & 0xFF) + "." +               ( ipAddress  >> 24 & 0xFF) ;

//GPRS下获取手机ip 需设置<uses-permission android:name="android.permission.INTERNET"></uses-permission>

public String getLocalIpAddress()      {          try          {              for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements();)              {                 NetworkInterface intf = en.nextElement();                 for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();)                 {                     InetAddress inetAddress = enumIpAddr.nextElement();                     if (!inetAddress.isLoopbackAddress())                     {                         return inetAddress.getHostAddress().toString();                     }                 }             }          }          catch (SocketException ex)          {              Log.e("WifiPreference IpAddress", ex.toString());          }          return null;      }

//获取手机mac地址，直接用命令来获取，需要支持busybox 命令

public String getMacAddress(){        String result = "";          String Mac = "";     result = callCmd("busybox ifconfig","HWaddr");           //如果返回的result == null，则说明网络不可取     if(result==null){         return "网络出错，请检查网络";     }           //对该行数据进行解析     //例如：eth0      Link encap:Ethernet  HWaddr 00:16:E8:3E:DF:67     if(result.length()>0 && result.contains("HWaddr")==true){         Mac = result.substring(result.indexOf("HWaddr")+6, result.length()-1);         Log.i("test","Mac:"+Mac+" Mac.length: "+Mac.length());                   if(Mac.length()>1){             Mac = Mac.replaceAll(" ", "");             result = "";             String[] tmp = Mac.split(":");             for(int i = 0;i<tmp.length;++i){                 result +=tmp[i];             }         }         Log.i("test",result+" result.length: "+result.length());                 }     return result; }       public String callCmd(String cmd,String filter) {        String result = "";        String line = "";        try {         Process proc = Runtime.getRuntime().exec(cmd);         InputStreamReader is = new InputStreamReader(proc.getInputStream());            BufferedReader br = new BufferedReader (is);                      //执行命令cmd，只取结果中含有filter的这一行         while ((line = br.readLine ()) != null && line.contains(filter)== false) {                //result += line;             Log.i("test","line: "+line);         }                   result = line;         Log.i("test","result: "+result);     }        catch(Exception e) {            e.printStackTrace();        }        return result;    }

//获取mac地址，建议使用此方法

String mac = "";WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);WifiInfo wifiInfo = wifiManager.getConnectionInfo();mac = wifiInfo.getMacAddress();

//获取手机唯一标示

IMEI：仅仅对android手机有效，需要添加权限

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission>

TelephonyManager TelephonyMgr = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); String szImei = TelephonyMgr.getDeviceId();

打电话：

权限<uses-permission android:name="android.permission.CALL_PHONE">
</uses-permission>

Intent phoneIntent = new Intent("android.intent.action.CALL", Uri.parse("tel:"+ inputStr));
