Transferring data from onReceive to SQL database in Android Studio

I have an SQL database that works, and the broadcast receiver that functions, but I can't seem to get the info out of the database, into global variables (latInfo, LonInfo) so I can use them to enter data into the database. The BroadcastReceivergets it's information from a service that gets LocationManager gps coordinate and the location_text is a textview that is updated every time a new set of coordinates is set. 

@Override
    protected void onResume() {
        super.onResume();
        if(br == null){
            br = new BroadcastReceiver() {
                @Override
                public void onReceive(Context context, Intent z) {
                    //location_text.append("\n" + z.getExtras().get("coordinates"));
                    latInfo = (double) z.getExtras().get("latitude");
                    lonInfo = (double) z.getExtras().get("longitude");
                    String x = "Latitude: " + latInfo + ", Longitude: " + lonInfo + "\n";
                    location_text.append(x);

                }

            };

        }

        registerReceiver(br, new IntentFilter("location_update"));
    }

This is the method I want to implement to add data to the database simply put, once the data I can get into the global variables (lonInfo, latInfo) is registered by the class below, it calls another class to get the cell signal cdmaSignal and all three get inserted into the database.

public void infoCollection(){
        if(lonInfo != 0 && latInfo != 0){
            cdmaInfo = sl.cdmaSignal;

            SQLInfoDatabase sid = new SQLInfoDatabase(cdmaInfo,lonInfo,latInfo);

            cdmaSignal.setText(cdmaInfo);

            dbh.addInfo(sid);
        }
    }

How do I get the received data from the onReceive method to stay as global variables between updates of the Service?

you can make static variables or can use singleton class

below is sample of singleton class

public class SharedClass
{
    private static SharedClass sharedClass;

    // global variables
    public double latInfo, LonInfo;

    public static SharedClass getInstance()
    {
        if (sharedClass == null)
            sharedClass = new SharedClass();

        return sharedClass;
    }

    private SharedClass()
    {
    }
}

you can access latInfo or LonInfo from anywhere in application by doing this

SharedClass.getInstance().latInfo
SharedClass.getInstance().LonInfo
