目前供职于电信,只做电信的业务,故列表中只有电信的APN信息
/** * 电信APN列表 * @author wudongdong * */ public class APNNET { public static String CTWAP="ctwap"; public static String CTNET="ctnet"; }
获得APN的类型
/** * 获得APN类型 * @author wudongdong * */ public class ApnUtil { private static Uri PREFERRED_APN_URI = Uri .parse("content://telephony/carriers/preferapn"); /** * get apntype * @param context * @return */ public static 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("user")); if(user.startsWith(APNNET.CTNET)){ apntype=APNNET.CTNET; }else if(user.startsWith(APNNET.CTWAP)){ apntype=APNNET.CTWAP; } return apntype; } }
获得手机号码的话可以传IMSI码到指定接口,接口地址不方便说。
但可以透露一点,必须走CTWAP,这也是判断APN类型的原因
发现很多应用如果APN是走代理的话就不能联网,那么再介绍一下用APN设置网络的代理信息。
Cursor c = context.getContentResolver().query(PREFERRED_APN_URI, null, null, null, null); c.moveToFirst(); String proxy=c.getString(c.getColumnIndex("proxy")); if (!"".equals(proxy) && proxy!=null) { Properties prop = System.getProperties(); System.getProperties().put("proxySet", "true"); prop.setProperty("http.proxyHost", c.getString(c .getColumnIndex("proxy"))); prop.setProperty("http.proxyPort", c.getString(c .getColumnIndex("port"))); String authentication = c.getString(c.getColumnIndex("user")) + ":" + c.getString(c.getColumnIndex("password")); String encodedLogin = Base64.encode(authentication); uc.setRequestProperty("Proxy-Authorization", " Basic " + encodedLogin); } c.close();
