Android how to access location data in jpg

Question

I am creating an Android application that includes the ability to display images on a map.

How can I extract location data from a .jpg file (if there is location data)?

Thanks a lot, Todd.

Answer 1

There is a good tutorial on how to access exif data (which includes the GPS information you need) from jpg, which can help you:

The corresponding class is described in official documents:

Answer 2

Here is how I did it:

try { final ExifInterface exifInterface = new ExifInterface(imagePath); float[] latLong = new float[2]; if (exifInterface.getLatLong(latLong)) { // Do stuff with lat / long... } } catch (IOException e) { logger.info("Couldn't read exif info: " + e.getLocalizedMessage()); }
