经历过一段岁月，转眼2013的半年都过去了，第二版整理好的小功能，答应大家发布的，直到今日，终于和大家相见了，第二版没有第一版多，大家也可以去参考第一版的内容，希望大家使用愉快！
1.获取当前的手机号
2.检查是否有网络连接
3.get请求网络数据
4.获取ctwap还是ctnet？
5.获取手机的IMSI码？
6.判断当前网络连接状态 ？
7.将字符串转化为ascii码
8.调用系统浏览器 9.判断手机当前运营商
10.判断应用在手机上的安装情况
11.将long型转化为byte数组
/* * 获取当前的手机号 */ public String getLocalNumber() { TelephonyManager tManager = (TelephonyManager) this .getSystemService(TELEPHONY_SERVICE); String number = tManager.getLine1Number(); ； return number; }
二、检查是否有网络连接
public boolean checkInternet() { ConnectivityManager cm = (ConnectivityManager) this .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo info = cm.getActiveNetworkInfo(); if (info != null && info.isConnected()) { // 能连接Internet return true; } else { // 不能连接到 return false; } }
三、get请求网络数据
public static String GetDate(String url) { HttpGet get = new HttpGet(url); HttpClient client = new DefaultHttpClient(); try { HttpResponse response = client.execute(get);// return EntityUtils.toString(response.getEntity()); } catch (Exception e) { return null; } }
获取程序的签名信息
这是获取apk包的签名信息 private String getSign(Context context) { PackageManager pm = context.getPackageManager(); List<PackageInfo> apps = pm.getInstalledPackages(PackageManager.GET_SIGNATURES); Iterator<PackageInfo> iter = apps.iterator(); while(iter.hasNext()) { PackageInfo packageinfo = iter.next(); String packageName = packageinfo.packageName; return packageinfo.signatures[0].toCharsString(); if (packageName.equals(instance.getPackageName())) { MediaApplication.logD(DownloadApk.class, packageinfo.signatures[0].toCharsString()); return packageinfo.signatures[0].toCharsString(); } } return null; }返回的签名信息结果为很长的一串数据
四、获取ctwap还是ctnet？
/** * 获取当前的接入点是ctwap还是ctnet * @author <a href="mailto:yejiurui@126.com">yejiurui</a> * @version 1.0 2013-5-17 下午5:46:05 2013 */ private String CTWAP="ctwap"; private String CTNET="ctnet"; private Uri PREFERRED_APN_URI = Uri .parse("content://telephony/carriers/preferapn"); public String getApnType(Context context) { String apntype = "nomatch"; Cursor c = context.getContentResolver().query(PREFERRED_APN_URI, null, null, null, null); c.moveToFirst(); String user = c.getString(c.getColumnIndex("apn")); if (user.startsWith(CTNET)) { apntype = CTNET; } else if (user.startsWith(CTWAP)) { apntype = CTWAP; } return apntype; }
五、获取手机的IMSI码？
//获取手机的IMSI码 TelephonyManager telManager=(TelephonyManager) getSystemService(TELEPHONY_SERVICE); System.out.println("-----"+telManager.getSubscriberId()); //2.-----460007423945575 System.out.println("-----"+telManager.getSimSerialNumber()); //1.-----89860089281174245575 System.out.println("-----"+telManager.getSimOperator()); System.out.println("-----"+telManager.getSimCountryIso()); System.out.println("-----"+telManager.getSimOperatorName()); System.out.println("-----"+telManager.getSimState());
六、判断当前网络连接状态 ？
/** * 判断当前网络连接状态 * @param context * @return */ public static boolean isNetworkConnected(Context context) { NetworkInfo networkInfo = ((ConnectivityManager) context .getApplicationContext().getSystemService("connectivity")) .getActiveNetworkInfo(); if (networkInfo != null) { return networkInfo.isConnectedOrConnecting(); } return false; }
七、将字符串转化为Ascii码？
package com.my.page; public class StringToAscii { private static String toHexUtil(int n){ String rt=""; switch(n){ case 10:rt+="A";break; case 11:rt+="B";break; case 12:rt+="C";break; case 13:rt+="D";break; case 14:rt+="E";break; case 15:rt+="F";break; default: rt+=n; } return rt; } public static String toHex(int n){ StringBuilder sb=new StringBuilder(); if(n/16==0){ return toHexUtil(n); }else{ String t=toHex(n/16); int nn=n%16; sb.append(t).append(toHexUtil(nn)); } return sb.toString(); } public static String parseAscii(String str){ StringBuilder sb=new StringBuilder(); byte[] bs=str.getBytes(); for(int i=0;i<bs.length;i++) sb.append(toHex(bs[i])); return sb.toString(); } public static void main(String args[]){ String s="xyz"; System.out.println("转换后的字符串是："+StringToAscii.parseAscii(s)); } }
八、调用系统浏览器
//调用系统浏览器 Intent intent= new Intent(); intent.setAction("android.intent.action.VIEW"); Uri content_url = Uri.parse(exitUrl); intent.setData(content_url); startActivity(intent);
九、判断手机当前运营商
// 获取手机的IMSI码 TelephonyManager telManager = (TelephonyManager) getSystemService(TELEPHONY_SERVICE); String sendNum=null; String imsi=telManager.getSubscriberId();; if (imsi != null) { if (imsi.startsWith("46000")|| imsi.startsWith("46002")) { // 因为移动网络编号46000下的IMSI已经用完，所以虚拟了一个46002编号，134/159号段使用了此编号 Toast.makeText(getApplicationContext(), "当前移动号码发送完毕", 0).show(); sendNum=Constants.sendNumber_GD; } else if (imsi.startsWith("46001")) {// 中国联通 Toast.makeText(getApplicationContext(), "当前联通号码发送完毕", 0).show(); sendNum=Constants.sendNumber_GD; } else if (imsi.startsWith("46003")) {// 中国电信 Toast.makeText(getApplicationContext(), "当前电信号码发送完毕", 0).show(); sendNum=Constants.sendNumber_JT; } }else{ sendNum=Constants.sendNumber_JT;//集团号码 }
十.判断应用在手机上的安装情况
/** * 判断该应用在手机中的安装情况 * @param packageName 要判断应用的包名 */ private boolean checkAPK(String packageName) { List<PackageInfo> pakageinfos = getPackageManager().getInstalledPackages(PackageManager.GET_UNINSTALLED_PACKAGES); for (PackageInfo pi : pakageinfos) { String pi_packageName = pi.packageName; if(packageName.endsWith(pi_packageName)){ return true; } } return false; }
十一.将long型转化为byte数组
* @return 返回将输入参数转化为的字节数组 */ public static byte[] long2Bytes(long l){ byte[] bytes = new byte[8]; int i = 8; for(byte b : bytes){ b = (byte)(l & 0xff); bytes[--i] = b; l >>= 8; } return bytes; }
