Get Meta Data of Image - Android

Question

http://www.isco.com/webproductimages/appBnr/bnr1.jpg

I've used a website to see the metadata of a image. In this website, it shows all info of image. I want to know how to get the "Title" tag of above image in android.

I found here the similiar question for iOS only: How to get image metadata in ios

However I don't know how to get "Meta data" of image on android. ExifInterface only gives some informations. But I'm unable to get "Title" tag with it.

Can you provide any code snippet for get meta data in android for image?

Answer 1

Download metadata extractor from the link given here ...... click to download the library choose the version 2.5.0.RC-3.zip

Extract the jar Folder

and import jar into libs folder in your poject and then execute the below code

        try {
            InputStream is = new URL("your image url").openStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            Metadata metadata = ImageMetadataReader.readMetadata(bis,true);


    for (Directory directory : metadata.getDirectories()) {
    for (Tag tag : directory.getTags()) {
        System.out.println(tag);
    }
 }

            }
        catch (ImageProcessingException e){}
        catch (IOException e) {}

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.
