    <p>I've researched and tried numerous options to try and get this to work, but am not getting anywhere with this unfortunately.</p> <p>What I am trying to do is set the Date Taken tag (Tag_DateTime) in a JPEG's Exif data from within an Android app. I already have working code to set the Latitude and Longitute tags, but cannot for the life of me get the Date taken tag to set.</p> <p>Here is the code:</p> <pre><code>SimpleDateFormat fmt_Exif = new SimpleDateFormat("yyyy:MM:dd HH:mm:ss"); try { ExifInterface exif = new ExifInterface(filePhoto.getPath()); // Set and save the GPS and time data exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE, strLat); exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE, strLong); exif.setAttribute(ExifInterface.TAG_DATETIME, fmt_Exif.format(locLatestLocation.getTime())); exif.saveAttributes(); } catch (IOException e) { e.printStackTrace(); } </code></pre> <ul> <li>locLatestLocation - Location being used to get the time in milliseconds.</li> <li>fmt_Exif - SimpleDateFormat used to format the millisecond time into the correct format for the TAG_DateTime Exif tag.</li> <li>strLat &amp; strLong - Populated elsewhere in the correct format to set the Latitude and Longitude tags.</li> </ul> <p>I read in a post somewhere that the tag needs to be written in the milliseconds format, so have tried this too to no avail. In order to confirm my formatting with what is actually stored, I read and outputted the unformatted tag from a jpeg file which has the Date Taken tag, but the output is in exactly the same format as what I am writing to the tag and its still not working.</p> <p>It might also be worth mentioning that I have looking into the Sanselan class to do this, and due to the complexity and lack of examples would much rather try and get my existing solution working before changing to a completely different one.</p> <p>Has anyone managed to do this and if so what am I doing wrong??</p>

    1. CODid you found any solution? If I try to set the "DateTime" field, there are two such fields in EXIF data after saving...

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
