Please help me.. I have a problem in sending multiple SMS in which it will send to the contact numbers that are registered in my application. The contact numbers are stored in SQLite. The body of that SMS contains the current latitude and longitude of the user. There is no problem in sending when I have internet, but when I don't have an internet, the SMS won't send.

    gps = new GPSTracker(NotAutoSOSAlert.this);
    if(gps.canGetLocation()) {
            longi=gps.getLongitude();
            lati=gps.getLatitude();
        }
        else {
            gps.showSettingsAlert();
        }
        getLocation();

if(longi != 0 && lati != 0) {
                    SharedPreferences shared = getSharedPreferences("Profile", MODE_PRIVATE);
                    String name = (shared.getString("profileName", "Not Found"));

                    List<ContactsConstructor> contacts = db.getAllContacts();   

                    for (ContactsConstructor cn : contacts) {
                        getLocation();
                        if(name == "") {
                            getProfNameDialog();
                        }

                        Log.d("id", String.valueOf(cn.getID()));
                        Log.d("name", name);
                        Log.d("conName", String.valueOf(cn.getName()));
                        Log.d("num", String.valueOf(cn.getPhoneNumber()));

                            Log.d("both", "not null");
                            String sms2 = cn.getID() + " " + name + " " + cn.getName() + " Help me!!.. My life is in danger!!.. "
                                    + "Here is my location latitude " + lati + " longitude " + longi 
                                    + " https://maps.google.com/?q=" + lati + "," + longi;
                            String sms1 = "1 " + name + " venom Help me!!.. My life is in danger!!.. "
                                    + "Here is my location latitude " + lati + " longitude " + longi 
                                    + " https://maps.google.com/?q=" + lati + "," + longi;
                            String cp = cn.getPhoneNumber();

                            PendingIntent piDelivered=PendingIntent.getBroadcast(NotAutoSOSAlert.this, 0, new Intent("SMS_DELIVERED"), 0);

It only logs the 1st contact registered in my application. Please help me Guys.. Thank you in advance!

I already solved it guys. The user just needs to check the Use Wireless Networks under the Location & Security Menu of Android Phone regardless if the user is connected to the WiFi

The problem now is, how can I check if the user checks the Wireless Networks under the Location & Security Menu of Android Phone? Please Help me with these

  • so what you want to do is check if wireless networks is available ? –  Jan 26 '14 at 06:39
