Answer 1

If you want to retrieve meta data information about an image ExifInterface is what you are looking for. Here is a quite good example of how this interface is used: http://android-er.blogspot.com/2009/12/read-exif-information-in-jpeg-file.html

But if you want to retrieve information of an online image I'm afraid it's not yet possible.

            Metadata metadata = ImageMetadataReader.readMetadata(bis,true);

If you want to retrieve metadata from image in Android project, then you can do that with the help of: https://github.com/drewnoakes/metadata-extractor

Implement this in your gradle using

implementation 'com.drewnoakes:metadata-extractor:2.12.0'

Complete code is as follows

private static String getImageMetaData(Uri image1) {
    try {
        InputStream inputStream = FILE_CONTEXT.getContentResolver().openInputStream(image1);
        try {
            image1.getEncodedUserInfo();
            Metadata metadata = ImageMetadataReader.readMetadata(inputStream);

            for (Directory directory1 : metadata.getDirectories()) {
                if (directory1.getName().equals("Exif IFD0")) {
                    for (Tag tag : directory1.getTags()) {
                        if (tag.getTagName().equals("Date/Time")) {
                            return tag.getDescription();
                        }
                    }
                }
            }
        } catch (ImageProcessingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    }
    return null;
}
