How to get information of an image without using MediaStore?

Postby quanganh12 » Thu Jul 15, 2010 11:13 am

Hi everybody, I spent many days to find out how to get the information of an image without using MediaStore database such as Datetaken, description... But all the ways I tried it didn't work. Could someone help me?
I'm totally new to this.

I think you MIGHT be talking about the header data that its supplied with jpegs?
If so you can get some java help here:

Thank for your help! I already used ExifInterface in Android API. But that only applies for JPEG, how can I do that with PNG file?

I didn't mean to be lazy and use the API , the website merely links to the source code and other resources to enable you to code this yourself into an application with probably half the memory footprint of a pumped up J2SE API.
