我的應用程序需要在有免費公共WiFi網絡的工作場所/機場工作。如何檢測用戶何時連接到公共WiFi但未獲批准wifi使用條款
我想通知用戶何時需要通過網絡瀏覽器批准wifi使用條款。
我試圖提取信息,但沒有發現任何屬性/信息隔離這種情況下
public static void haveNetworkConnection(Context mContext) {
ConnectivityManager cm = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
if (activeNetwork != null) { // connected to the internet
if (activeNetwork.getType() == ConnectivityManager.TYPE_WIFI) {
// connected to wifi
Toast.makeText(mContext, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
printWifiInformation(activeNetwork);
} else if (activeNetwork.getType() == ConnectivityManager.TYPE_MOBILE) {
// connected to the mobile provider's data plan
Toast.makeText(mContext, activeNetwork.getTypeName(), Toast.LENGTH_SHORT).show();
}
} else {
Toast.makeText(mContext, "Not connected", Toast.LENGTH_SHORT).show();
}
}
public static void printWifiInformation(NetworkInfo activeNetwork){
System.out.println("************************************************************************************");
System.out.println("1 . describeContents " + activeNetwork.describeContents());
System.out.println("2 . getDetailedState " + activeNetwork.getDetailedState());
System.out.println("3 . getExtraInfo " + activeNetwork.getExtraInfo());
System.out.println("4 . getReason " + activeNetwork.getReason());
System.out.println("5 . getState " + activeNetwork.getState());
System.out.println("6 . getSubtype " + activeNetwork.getSubtype());
System.out.println("7 . getSubtypeName " + activeNetwork.getSubtypeName());
System.out.println("8 . getSubtypeName " + activeNetwork.getSubtypeName());
System.out.println("9 . getType " + activeNetwork.getType());
System.out.println("10. getTypeName " + activeNetwork.getTypeName());
System.out.println("11. isAvailable " + activeNetwork.isAvailable());
System.out.println("12. isConnected " + activeNetwork.isConnected());
System.out.println("13. isConnectedOrConnecting " + activeNetwork.isConnectedOrConnecting());
System.out.println("14. isFailover " + activeNetwork.isFailover());
System.out.println("15. isRoaming " + activeNetwork.isRoaming());
System.out.println("************************************************************************************");
}
我得到了相同的結果時,我之前並點擊網頁瀏覽器後進行檢查。 請指教,謝謝 , 路德
您可以嘗試「ping」此服務器,如果它現在連接,它將無法工作。 –
