Add Metadata To Created Bitmap In Android

I am using a camera intent to take pictures, then I convert that image to a bytearray and eventually save it locally in my database. The original image taken with the camera has al

Solution 1:

Meta data is not a property of bitmap. it is stored as Exinf of JPEG file. use ExifInterface to update meta data here is an example to set gps cordinates

exif = new ExifInterface(imageFile.getAbsolutePath());
        int num1Lat = (int) Math.floor(latitude);
        int num2Lat = (int) Math.floor((latitude - num1Lat) * 60);
        double num3Lat = (latitude - ((double) num1Lat + ((double) num2Lat / 60))) * 3600000;

        int num1Lon = (int) Math.floor(longitude);
        int num2Lon = (int) Math.floor((longitude - num1Lon) * 60);
        double num3Lon = (longitude - ((double) num1Lon + ((double) num2Lon / 60))) * 3600000;

        exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE, num1Lat + "/1," + num2Lat + "/1," + num3Lat + "/1000");
        exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE, num1Lon + "/1," + num2Lon + "/1," + num3Lon + "/1000");

        if (latitude > 0) {
            exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE_REF, "N");
        } else {
            exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE_REF, "S");
        }

        if (longitude > 0) {
            exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF, "E");
        } else {
            exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE_REF, "W");
        }
        exif.setAttribute(ExifInterface.TAG_MAKE, "FooBarr");
        exif.setAttribute(ExifInterface.TAG_MODEL, "KooKKoo");
        exif.setAttribute(ExifInterface.TAG_ORIENTATION,orientation+"");
        exif.saveAttributes();
