How to get location and other information from image in Android?

There are many questions like this, and of course I followed them, but did not get any success. I tried this , this and this . and is done as described. Here is what I am doing: InonActivityResult...()

ExifInterface exifInterface = null;
    try {
        exifInterface = new ExifInterface(filepathwithname+ ".Jpg");
        MyGeoDegree myGeoDegree = new MyGeoDegree(exifInterface);
        Log.i("LAT", String.valueOf(myGeoDegree.getLatitudeE6()));
        Log.i("LNG",String.valueOf(myGeoDegree.getLongitudeE6()));
    } catch (IOException e) {
        e.printStackTrace();
    }

also try only with the file name with the extension. and passed this exifInterface to this class (described in one of the links)

public class MyGeoDegree {
private boolean valid = false;
Float Latitude, Longitude;

public MyGeoDegree(ExifInterface exif) {
    String attrLATITUDE = exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE);
    String attrLATITUDE_REF = exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE_REF);
    String attrLONGITUDE = exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE);
    String attrLONGITUDE_REF = exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF);

    if ((attrLATITUDE != null)
            && (attrLATITUDE_REF != null)
            && (attrLONGITUDE != null)
            && (attrLONGITUDE_REF != null)) {
        valid = true;

        if (attrLATITUDE_REF.equals("N")) {
            Latitude = convertToDegree(attrLATITUDE);
        } else {
            Latitude = 0 - convertToDegree(attrLATITUDE);
        }

        if (attrLONGITUDE_REF.equals("E")) {
            Longitude = convertToDegree(attrLONGITUDE);
        } else {
            Longitude = 0 - convertToDegree(attrLONGITUDE);
        }

    }
}

;

private Float convertToDegree(String stringDMS) {
    Float result = null;
    String[] DMS = stringDMS.split(",", 3);

    String[] stringD = DMS[0].split("/", 2);
    Double D0 = new Double(stringD[0]);
    Double D1 = new Double(stringD[1]);
    Double FloatD = D0 / D1;

    String[] stringM = DMS[1].split("/", 2);
    Double M0 = new Double(stringM[0]);
    Double M1 = new Double(stringM[1]);
    Double FloatM = M0 / M1;

    String[] stringS = DMS[2].split("/", 2);
    Double S0 = new Double(stringS[0]);
    Double S1 = new Double(stringS[1]);
    Double FloatS = S0 / S1;

    result = new Float(FloatD + (FloatM / 60) + (FloatS / 3600));

    return result;


}

;

public boolean isValid() {
    return valid;
}

@Override
public String toString() {
    // TODO Auto-generated method stub
    return (String.valueOf(Latitude)
            + ", "
            + String.valueOf(Longitude));
}

public int getLatitudeE6() {
    return (int) (Latitude * 1000000);
}

public int getLongitudeE6() {
    return (int) (Longitude * 1000000);
}
}

But getting this error in the log:
