First, get the current mobile phone number
* * Get current cell phone number/public String Getlocalnumber () {Telephonymanager Tmanager = (Telephonymanager) . Getsystemservice (Telephony_service); String number = Tmanager.getline1number (); ; return number; }
Second, check if there is a network connection
public boolean checkinternet () {Connectivitymanager cm = (Connectivitymanager) this. Getsystemservice (conte Xt. Connectivity_service); Networkinfo info = Cm.getactivenetworkinfo (); if (info!= null && info.isconnected ()) {//can connect to Internet return true; else {//cannot connect to return false; } }
third, GET request network data
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; } }
Obtain the signature information of the program
//This is the signature information for obtaining the APK package 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; }
The signature information returned by the
results in a long string of data
four, get Ctwap or ctnet?
/** * Get the current access point is Ctwap or ctnet * @author <a href= "mailto:yejiurui@126.com" >yejiurui</a> * @versio N 1.0 2013-5-17 pm 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 {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; }
Five, get the phone IMSI code?
Get the phone's IMSI code 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 ());
Six, determine the current network connection status?
/** * To determine the current network connection status * @param context * @return/public static Boolean isnetworkconnected (context Contex T) {Networkinfo networkinfo = (connectivitymanager) context. Getapplicationcontext (). Getsystemservice ("Connectivity ")). Getactivenetworkinfo (); if (networkinfo!= null) {return networkinfo.isconnectedorconnecting (); return false; }
Seven, convert a string to an ASCII code?
package com.my.page; public class Stringtoascii {private static String tohexutil (int n) {string rt= ""; Switch (n) {case 10:rt+= "A"; Case 11:rt+= "B"; Case 12:rt+= "C"; Case 13:rt+= "D"; Case 14:rt+= "E"; Case 15:rt+= "F"; 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 ("Converted string is:" +stringtoascii.parseascii (s)); } }
Eight, call the system browser
Call the System browser Intent intent= new Intent (); Intent.setaction ("Android.intent.action.VIEW"); Uri Content_url = Uri.parse (Exiturl); Intent.setdata (Content_url); StartActivity (Intent);
Nine, Judge mobile phone current operator
Get the phone's IMSI code telephonymanager Telmanager = (telephonymanager) getsystemservice (Telephony_service); String Sendnum=null; String Imsi=telmanager.getsubscriberid ();; if (IMSI!= null) {if (Imsi.startswith ("46000") | | imsi.startswith ("46002")) {//Because IMSI has run out of mobile network number 46000, virtual a 46002 The number 134/159th segment uses this number Toast.maketext (Getapplicationcontext (), "The current mobile number is sent", 0). Show (); SENDNUM=CONSTANTS.SENDNUMBER_GD; else if (Imsi.startswith ("46001")) {//China Unicom Toast.maketext (Getapplicationcontext (), "Current Unicom number Sent", 0). Show (); SENDNUM=CONSTANTS.SENDNUMBER_GD; else if (Imsi.startswith ("46003")) {//China Telecom Toast.maketext (Getapplicationcontext (), "Current telecommunications number sent out", 0). Show (); SENDNUM=CONSTANTS.SENDNUMBER_JT; }}else{sendnum=constants.sendnumber_jt;//Group number}
10. Judge the installation of the application on the phone
/** * To determine the application in the mobile phone installation situation * @param packagename to determine the application of the package name */Private Boolean checkapk (String packagename) {LIST<PA ckageinfo> 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; }
11. Converts a long type to a byte array. * @return returns the byte array to convert input parameters to/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; }
