添加APN网络接入点，设置指定网络为默认网络
来源：互联网 发布：淘宝老兵蜜蜡是真的吗 编辑：程序博客网 时间：2024/04/27 23:09
网上看了很多资料，再加上自己的理解和探索，终于实现了添加接入点设置和将当前网络设置为自己指定的网络接入点。废话不多说，上源码，大家分享下：（在moto-xt800，CDMA下进行了测试）
1.准备工作：
AndroidManifest。xml文件里添加以下三个权限设置：
<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_NETWORK_STATE" />
开始上代码了，很期待吧？
2.新建一个类ApnNode，算是属性设置吧
public class ApnNode {
private String name ;
private String apn ;
private String proxy ;
private String port;
private String user;
private String server;
private String password;

this.apn = apn;
}

}

return mmsproxy;
}
/**

*/

this.mmsproxy = mmsproxy;
}
/**

*/
public String getMmsport() {
return mmsport;
}
/**
* @param mmsport the mmsport to set
*/
public void setMmsport(String mmsport) {
this.mmsport = mmsport;
}
/**
* @return the mcc
*/
public String getMcc() {
return mcc;
}
/**
* @param mcc the mcc to set
*/
public void setMcc(String mcc) {
this.mcc = mcc;
}
/**
* @return the mnc
*/
public String getMnc() {
return mnc;
}
/**
* @param mnc the mnc to set
*/
public void setMnc(String mnc) {
this.mnc = mnc;
}
/**
* @return the numeric
*/
public String getNumeric() {
return numeric;
}
/**
* @param numeric the numeric to set
*/
public void setNumeric(String numeric) {
this.numeric = numeric;
}
/**
* @return the type
*/
public String getType() {
return type;
}
/**
* @param type the type to set
*/
public void setType(String type) {
this.type = type;
}
}
如果里面的函数名不清楚的话，网上找APN设置，一大堆的资料
