Writing EXIF metadata to images in Android

Question

Hi, I want to store some metadata in images. My camera application gives me a bitmap, which I store in the storage (MediaStore) device. In addition to this, I want to add a few tags to the picture in its metadata. I think EXIF is a good way of doing this. But I couldn't find good references on how to do this.

If there are some tools to achieve this task in Android programming, please let me know.

Thanks

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
