How to get the latitude and longitude of an image in an SD card in my application?

From my application, I can open the gallery. Is there any way to get the latitude and longitude of any selected image in the gallery for my application?

You must go with the ExifInterface class to read various EXIF ​​metadata from images:

Example:

ExifInterface exif = new ExifInterface(filepath);
exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE);
exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE_REF);
exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE);
exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF);

Edited by:

Now you will get lat-long as the format below.

lat = 30 / 1.12 / 1.34 / 1, length = 81 / 1.22 / 1.41 / 1

To translate this into real meaning, this blog has helped me.

we need to do the conversion from the form, minute, second form to the GeoPoint form.

Below you can do it.

 String LATITUDE = exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE);
 String LATITUDE_REF = exif.getAttribute(ExifInterface.TAG_GPS_LATITUDE_REF);
 String LONGITUDE = exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE);
 String LONGITUDE_REF = exif.getAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF);

 // your Final lat Long Values
 Float Latitude, Longitude;

 if((LATITUDE !=null)
   && (LATITUDE_REF !=null)
   && (LONGITUDE != null)
   && (LONGITUDE_REF !=null))
 {

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

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

 }

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;


};



@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);
}

"buildin":

ExifInterface exif = new ExifInterface(path);
float[] latLong = new float[2];
boolean hasLatLong = exif.getLatLong(latLong)
if (hasLatLong) {
    System.out.println("Latitude: " + latLong[0]);
    System.out.println("Longitude: " + latLong[1]);
}
