One of the most important attributes when it comes to displaying images is the image orientation, stored in the aptly-namedĬonstants. Var exif : ExifInterface = ExifInterface(pictureFile.getAbsolutePath())Įxif.setAttribute(ExifInterface.TAG_ORIENTATION, "" + getPhotoOrientation(configurationProvider.getSensorPosition())) We can also remove these attributes based on the user's request. We can easily alter the already set JPEG_ORIENTATION, JPEG_GPS_LOCATION, or the equivalent. As of now, it's still limited to JPEG images. It is strongly recommended to only use them with content:// or file:// URIs.įor Camera apps, after capturing the image writing attributes is more important. Note: ExifInterface will not work with remote InputStreams, such as those returned from a HttpURLConnection. Assuming the image is a JPEG or supported raw format Now you can extract any Exif tag you want In = getContentResolver().openInputStream(uri) ĮxifInterface exifInterface = new ExifInterface(in) Uri uri // the URI you've received from the other app For most attributes, you'd simply use the getAttributeInt(), getAttributeDouble(), or getAttribute() (for Strings) methods as appropriate. Now let us understand how can we read EXIF attributes for different sources and some of the use cases using ExifInterface. Therefore throughout your code, you should always handle cases where there is no Exif data, either due to no data for a specific attribute or an image format that doesn't support Exif data at all (say, the ubiquitous PNGs or WebP images). One thing that is important to understand with Exif data is that there are no required tags: every tag is optional - some services even specifically strip Exif data. Implementation "androidx.exifinterface:exifinterface:1.3.1" If you want to use ExifInterface you need to add the below dependency to your adle. The supported formats are JPEG, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW, RAF, and HEIF. For now, it can only read the Exif of JPEG files or a RAW image file. This has been added with 100+ attributes to read the Exif tags of the images including information about the camera itself, the camera settings, orientation, and GPS coordinates. Even though this has been existing since 7.1, It made sense from android 9+ with all the capabilities provided to the interface. ExifInterface has been introduced in the android support library since 25.1.0. Let’s see how can we extract Exif data from images in Android. We understood what is Exif and what it contains. Now you may get a fair idea of EXIF files. By looking at this we can get the complete details of the image. If you look at the above image, We have attributes like Image length and width, date and time of the image taken, From which device this image was taken, Orientation code, and some of the images attribute like light, white balance, focal length, if the flash was on or not, GPS information of the image i.e lat long of the image where it was taken. It is capable of storing such important data as camera exposure, date/time the image was captured, and even GPS location. This is a standard that defines specific information related to an image or other media captured by a camera. The solution for these is Exif files and ExifInterface. Even though when we read, the changes to the images like removing GPS tags or changing the orientation would be challenging tasks. Previously we were struggling to get image info, for which we had to separately extract metadata from different methods and read it to understand the Image properties. There might be needs to know the image details like GPS location, date/time, settings at the time of capture, orientation, etc. But we cannot read the details of the images always directly from the image. For some of the Image Related Applications, all the details of the images are required.
