android的日积月累-进行WIFI,CMWAP和CMNET的自动判断访问
智能进行WIFI,CMWAP和CMNET的自动判断访问
引用文件:
import android.app.AlertDialog;
import android.content.BroadcastReceiver;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.database.Cursor;
import android.database.SQLException;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.net.Uri;
import android.net.wifi.WifiManager;
import android.telephony.TelephonyManager;

变量定义
Cursor cursor_current,cursor_need;
Uri PREFERRED_APN_URI, APN_TABLE_URI;
int newCreateAPN_Id;
String APN_Id;
TelephonyManager tm;
WifiManager wifi;
String strAPN;
使用到的函数如下：
//获取当前APN属性
private boolean getCurrentAPN(){
PREFERRED_APN_URI = Uri.parse("content://telephony/carriers/preferapn");
cursor_current = this.getContentResolver().query(PREFERRED_APN_URI, null, null, null, null);
if(cursor_current != null && cursor_current.moveToFirst()){
String proxy = cursor_current.getString(cursor_current.getColumnIndex("proxy"));
String apn = cursor_current.getString(cursor_current.getColumnIndex("apn"));
String port = cursor_current.getString(cursor_current.getColumnIndex("port"));
String current = cursor_current.getString(cursor_current.getColumnIndex("current"));
if(proxy == null || apn == null || port == null || current == null
|| proxy.equals("") || port.equals("")){
return false;
}
if((proxy.equals("10.0.0.172") || proxy.equals("010.000.000.172")) && port.equals("80") &&
apn.equals("cmwap") && current.equals("1")){
return true;
}
}
return false;
}
//检查是否存在cmwap网络
private boolean checkHasWapAPN(){
APN_TABLE_URI = Uri.parse("content://telephony/carriers");
cursor_need = this.getContentResolver().query(APN_TABLE_URI, null, null, null, null);
while(cursor_need != null && cursor_need.moveToNext()){
String id = cursor_need.getString(cursor_need.getColumnIndex("_id"));
String port = cursor_need.getString(cursor_need.getColumnIndex("port"));
String proxy = cursor_need.getString(cursor_need.getColumnIndex("proxy"));
String current = cursor_need.getString(cursor_need.getColumnIndex("current"));
String mmsc = cursor_need.getString(cursor_need.getColumnIndex("mmsc"));
if(proxy == null || port == null || current == null){
continue;
}
if((proxy.equals("10.0.0.172") || proxy.equals("010.000.000.172"))
&& port.equals("80") && current.equals("1")
&& mmsc == null){
APN_Id = id;
return true;
}
}
return false;
}
//设置为cmwap网络
public boolean setAPN(int id){
boolean res = false;
ContentResolver resolver = this.getContentResolver();
ContentValues values = new ContentValues();
values.put("apn_id", id);
try{
resolver.update(PREFERRED_APN_URI, values, null, null);
Cursor c = resolver.query(PREFERRED_APN_URI, new String[]{"name", "apn"}, "_id=" + id, null, null);
if(c != null){
res = true;
c.close();
}
}catch(SQLException e){
Log.e("lhl", e.getMessage());
}
return res;
}
//添加cmwap网络
private int addCmwapAPN(){
ContentResolver cr = this.getContentResolver();
ContentValues cv = new ContentValues();
cv.put("name", "cmwap");
cv.put("apn", "cmwap");
cv.put("proxy", "010.000.000.172");
cv.put("port", "80");
cv.put("current", 1);
tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
String imsi =tm.getSubscriberId();
if(imsi != null){
if(imsi.startsWith("46000")){
cv.put("numeric", "46000");
cv.put("mcc", "460");
cv.put("mnc", "00");
}
else if(imsi.startsWith("46002")){
cv.put("numeric", "46002");
cv.put("mcc", "460");
cv.put("mnc", "02");
}
}
Cursor c = null;
try{
Uri newRow = cr.insert(APN_TABLE_URI, cv);
if(newRow != null){
c = cr.query(newRow, null, null, null, null);
c.moveToFirst();
String id = c.getString(c.getColumnIndex("_id"));
setAPN(Integer.parseInt(id));
return Integer.parseInt(id);
}
}catch(SQLException e){
Log.e("lhl", e.getMessage());
}
finally{
if(c != null){
c.close();
}
}
return 0;
}
判断逻辑如下：
private Search search;
//网络判断
//如果wifi是打开的，则直接调用就可以了
wifi = (WifiManager)getSystemService(Context.WIFI_SERVICE);
if(wifi.isWifiEnabled()){
strAPN = "WIFI";
search.asyncRequest(queryCompanyName, queryDttime, queryBeginCity, queryEndCity, queryBeginCity1, queryEndCity1, strAPN, listener);
return;
}
boolean isCmwap = getCurrentAPN();
boolean wCheckWapApn = checkHasWapAPN();
if(!isCmwap){
if(!wCheckWapApn){
newCreateAPN_Id = addCmwapAPN();
strAPN = "CMNET";
}
else{
strAPN = "CMNET";
}try{
Thread.sleep(1000);
}catch(InterruptedException e){
e.printStackTrace();
}
}
else{
strAPN = "CMWAP";
}
//异步调用
search.asyncRequest(woeid, strAPN, listener);
//异步调用类：
package com.search.weather;
import com.search.RequestListener;
import com.search.common.HttpUtils;
import android.os.Bundle;
import android.util.Log;
/**
* 查询类
* @author Administrator
*
*/
public class Search {
private static final String HTTP_URL = "http://sds.XXXXXX.com/getinfo";
private static final String HTTP_WAP_URL = "http://10.0.0.172/getinfo";
private static final String METHOD = "GET";
private static final String LOG_TAG = "XXX";
public String request(String strAPN){
if(woeid != null){
Bundle params = new Bundle();
if (strAPN.equals("CMWAP"))
{
return HttpUtils.openUrl1(HTTP_WAP_URL, METHOD, params,null,strAPN);
}
else
{
return HttpUtils.openUrl(HTTP_URL, METHOD, params,null,strAPN);
}
}else{
return null;
}
}
//异步封装
public void asyncRequest(final String strAPN, final RequestListener listener){
new Thread(new Runnable() {
@Override
public void run() {
try {
String response = request(strAPN);
listener.onComplete(response);
} catch (Exception e) {
Log.e(LOG_TAG, e.getMessage());
listener.onException(e);
}
}
}).start();
}
}
对于CMWAP的方法需要做以下逻辑处理：
public static String openUrl(String url, String method, Bundle params, String enc, String strAPN){
String response = null;
if(method.equals("GET")){
url = url + "?" + encodeUrl(params);
}
try {
//Log.d(LOG_TAG, "Url:"+url);
HttpURLConnection conn = (HttpURLConnection) new URL(url).openConnection();
conn.setRequestProperty("User-Agent", System.getProperties()
.getProperty("http.agent")
);
if (strAPN.equals("CMWAP"))
{
conn.setRequestProperty("X-Online-Host", "sds.XXXXXX.com");//这里需要换成调用的真正的网址
conn.setDoInput(true);
}
conn.setConnectTimeout(30000);
conn.setReadTimeout(30000); //设置超时时间
if(method.equals("POST")){
conn.setRequestMethod("POST");
conn.setDoOutput(true);
conn.getOutputStream().write(encodeUrl(params).getBytes("UTF-8"));
}
response = read(conn.getInputStream(),enc);
} catch (Exception e) {
//Log.e(LOG_TAG, e.getMessage());
throw new RuntimeException(e.getMessage(),e);
}
return response;
}
最后还要在AndroidManifest.xml加上以下权限：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
<uses-permission android:name="android.permission.WRITE_APN_SETTINGS"></uses-permission>
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>
