This is far slower than obtaining the data directly from MediaStore, so ideally you are not attempting to get this data in bulk. This is not dependent upon targetSdkVersion - MediaStore simply does not seem to aggregate this data.Īs a result, your only option appears to be to get the Uri for each individual image and use ExifInterface, as shown above.

However, that is not done on Android 10, and therefore you will be unable to obtain this data. That could then be accessed by querying the MediaStore for and values. MediaStoreĪs part of indexing the images available on external storage, the MediaStore used to examine the EXIF headers and save location data. Then, if you use openInputStream() for the setRequireOriginal()-supplied Uri, you will get a stream that includes the location EXIF tags.
Your app needs to call tRequireOriginal(), supplying the Uri for which you would like the location - this method then returns a decorated Uri that can be used with openInputStream(). Your app needs to hold the ACCESS_MEDIA_LOCATION permission (which is dangerous and needs to go through runtime permissions). However, we still can get the location information, even from the MediaStore. Has the file scheme (e.g., a file on the filesystem that you can access)īy default, we get null if the Uri came from the MediaStore. We get a valid location for images that have those EXIF tags if the Uri: For example, consider this function:įun gimmeTehTags ( image : Uri ) However, it does work, by default, for a Uri from the MediaStore. Content that you can access via the Storage Access Framework. Files that you can access on the filesystem. However, that does not seem to be working, at least for: Individual FilesĪccording to the documentation, EXIF data is supposed to be redacted when reading in images. This is less true of a photo created five months ago… but if there are a lot of photos in a similar area, there is a decent chance that the user lives in that area and is taking photos of local events.Īs a result, in Android 10, access to this information is much more restricted than it had been.Īt least, in theory it is. For example, if a photo was created five minutes ago and has GPS coordinates, it is reasonable to think that the device is still in the general vicinity. However, geotagged photos represent semi-intentional leaks of location information. This enables a lot of interesting features and services, such as allowing a user to browse a photo gallery via a map instead of only chronologically. 
A camera app can elect to include location information in photos as tags. “Geotagged” photos represent another set of EXIF tags.

This allows image-viewing code to rotate the image as needed to properly orient it for viewing. For example, one important one is orientation, indicating how the device was being held at the time the picture was taken.
