Get Meta Data of Image - Android

How to get all details of an image pragmatically available in Android phone gallery

you can use android's ExifInterface for doing this.
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 and RAF.

Refer it from here Android ExifInterface

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) {}

reading android jpeg EXIF metadata from picture callback

The bad news:

Android Api sadly won't allow you to read exif data from a Stream, only from a File.

ExifInterface don't have a constructor with an InputStream.
So you must parse jpeg content by yourself.

The good news:

API exists in pure Java for this. You can use this one: https://drewnoakes.com/code/exif/

It's Open Source, published under Apache Licence 2 and available as a Maven package.

There is a constructor with an InputStream:
public ExifReader(java.io.InputStream is)

You can build an InputStream backed by your byte[] using a ByteArrayInputStream like this:

InputStream is = new ByteArrayInputStream(decodedBytes);

Writing EXIF metadata to images in Android

Ok, Somebody (offline) pointed me to a useful resource. The ExifInterface looks like what I was searching for. Android-er has a post demonstrating how to read EXIF metadata in Android and I think writing should not be very different.

I don't know, but can we EXIF to write arbitrary metadata, ie. other than those specified in the ExifInterface documentation (like latitude, longitude, flash etc). If not, what could be a preferred method of writing arbitrary metadata to image files?

Thanks

I want to read exif info in image in android. I can read exif from image in gallery but i cannot read exif photo taken from the camera

You cannot read exif data from a Stream using the android api. ExifInterface doesn't have a constructor with an InputStream.

However, You can use the metadata-extractor
and use the constructor with an InputStream to build an InputStream backed by your byte[] using a ByteArrayInputStream
