I need to show all panorama photo in Gallery android. But it extension is jpg same regular photo.
How can I check a photo in Gallery android is Panorama photo?
Thanks
You'll need to extract the XMP Metadata
XMP Metadata is essentically image metadata...
...encoded in some XML-friendly format, such as Base64.
See this previous question/answers on StackOverflow to see how to decode Base64.
Based on the xml you can decode from the jpeg, you may be able to guess the intent-filter you'll need. In the case of a photo sphere panorama format for instance, this is the format.
If you want to accept Photo Sphere images in your own Android apps,
you can add the custom MIME type
application/vnd.google.panorama360+jpg to the relevant IntentFilter in
your app.
However, I'm not sure what type of panorama your jpeg is in. It may help if you posted the particular jpeg with your question.
Ask the mediadatabase through a filter condition
Where ((height/width > 2) or (width/height >= 2))
something like this
ContentResolver resolver = context.getContentResolver();
Cursor query = resolver.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
sqlSelectColums, '((height/width > 2) or (width/height >= 2))',
null, sqlSortOrder);

I understand that from api 29 we need to work with URI and Image id's to perform bitmap operations, but in order to migrate from image path to uri i'll need to drop real users databases and server databases, and if there is a way to avoid this i would like to try.
For example i got "FileNotFoundExeption: no content provider" error here:
BitmapFactory.decodeStream(context.getContentResolver().openInputStream(Uri.parse(path)), new Rect(), options);
Thanks!
edits:
path is absolute file path like /storage/emulated/0/DCIM/Camera/20200128_122949_020.jpg
Here in code snippet i'm trying to decode image bounds, e.g. to get width and height of image on filesystem by path of image.

I have to make an app to take a picture and showing geotag on it.
Even the captured image from camera or gallery has to show geotag on it for this requirement I searched a lot but I did not find any solution.
Can some one help me please?

This is a class for reading and writing Exif tags in a JPEG file or a RAW image file.Supported formats are: JPEG, DNG, CR2, NEF, NRW, ARW, RW2, ORF, PEF, SRW and RAF.
You can use ExifInterface to get metadata of any image and you can edit also.

In new android version, they have added gplus photo section in gallery.
In my application, i have incorporated the logic of selecting image from it and display to the user using below link of stackoverflow:
Download image from new Google+ (plus) Photos Application
However, i also need image extension as we are sending image raw data with extension of selected picture to the API. gplus returns the image path like this
content://com.google.android.apps.photos.content/0/https%3A%2F%2Flh5.googleusercontent.com%<a bunch of letters and numbers here>
So, how can i get extension of that image also from gplus?? Any idea??
I AM SUCCESSFULLY GETTING BITMAP FROM ABOVE URI. I JUST NEED EXTENSION OF THAT IMAGE NOW.
Thanks.
Use ContentResolver.getType(uri):
Uri uri = // your content://com.google.android.apps.photos.content URI
String mimeType = getContentResolver().getType(uri);
// mimeType will be image/png, image/jpeg, etc.
String picPath = "/mnt/sdcard/yepcolor/sina.png";
Bitmap bitmap = BitmapFactory.decodeFile(picPath);
I know the 'picPath' of the picture.Now, I want to get the picture's shooting time,and what should I do?Thanks.
As far as I know, png files doesn't contain such information. If you are reading jpeg files, however, you can use ExifInterface.
