Android save MediaStore image with mime type GIF

Question

While this code successfully creates an image that is also present in the phone's gallery, the extension is '.jpg' instead of '.gif'.

    File gifFile; // gif file stored in Context.getFilesDir()

    final ContentValues contentValues = new ContentValues();
    contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, "Image" + System.currentTimeMillis());
    contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/gif");

    // Create a new gif image using MediaStore
    final Uri gifContentUri = context.getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
    // Open a writable stream pointing to the new file created by MediaStore
    OutputStream outputStream = context.getContentResolver().openOutputStream(gifContentUri, "w");
    // Copy the original file from the app private data folder to the file created by MediaStore
    IOUtils.copyFile(new FileInputStream(gifFile), outputStream);

Output file is created inside Pictures folder by MediaStore. If I manually change the output file's extension to gif, the gif animation is playing inside Android gallery.

I feel I'm missing a small detail for this to work

Answer 1

Removed the DISPLAY_NAME line.

Add contentValues.put(MediaStore.MediaColumns.DATA, "/storage/emulated/0/Pictures/Image." + System.currentTimeMillis() + ".gif");

It goes to a subdir of the Pictures directory if the subdir exists contentValues.put(MediaStore.MediaColumns.DATA, "/storage/emulated/0/Pictures/Mine/Image." + System.currentTimeMillis() + ".gif");.

For Android Q the DATA column is useless.

String displayName = "Image." + System.currentTimeMillis() + ".gif";
contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, displayName);

will do it there.
