我做了一个网络监控应用程序.在这里,我成功地实现了所有的事情.我有双卡通android手机.我知道如何获得运营商的名称.但我想知道哪个SIM连接到互联网?我使用过此代码,仅向用户显示设备是通过移动数据连接的.我想更具体地说,该设备目前正在使用哪个运营商的互联网.
public static String isInternetConnected (Context ctx) {
ConnectivityManager connectivityMgr = (ConnectivityManager) ctx
.getSystemService(CONNECTIVITY_SERVICE);
NetworkInfo wifi = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo mobile = connectivityMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
// Check if wifi or mobile network is available or not. If any of them is
// available or connected then it will return true, otherwise false;
if (wifi != null) {
if (wifi.isConnected()) {
return "wifi";
}
}
if (mobile != null) {
if (mobile.isConnected()) {
return "mobile";
}
}
return "none";
}
