Android Gallery ACTION_PICK into single directory (bucket id)

Question

I want to implement an image picker using the default android Gallery. To launch this gallery i use this function:

private void launchGallery() {
  Intent intent = new Intent(
    Intent.ACTION_PICK,
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
  startActivityForResult(intent, GALLERY_TOKEN);

}

This all works great, the gallery is launched and i catch the result.

The problem however is that the gallery is launched in the top level view of all albums. My App has created a subdirectory in /mnt/sdcard/Pictures/App/Album1 Ofcourse Album1 can be a wildcard of names. My assignment is to launch this gallery straight into the selected folder instead of the top level view.

I tried the following but it doesnt work, could anyone help me with this problem?

private void launchGallery() {
    Intent intent = new Intent(Intent.ACTION_PICK);
    File file = new File("/mnt/sdcard/Pictures/App/Album/");
    intent.setDataAndType(Uri.fromFile(file), "image/*");
    startActivityForResult(intent, GALLERY_TOKEN);
}

Thanks alot!

-- EDIT --

Currently im looking into Bucket_ID as defined by the mediastore. This should hold the ID of the parent directory.

int bucketIdIndex = cursor
     .getColumnIndexOrThrow(Images.ImageColumns.BUCKET_ID);

For my file this prints a negative number.

03-30 13:40:21.923: D/ImageHelper(2208): Data: /mnt/sdcard/Pictures/App/bbb/gvv/376.jpg

Result is:

03-30 13:40:21.942: D/ImageHelper(2208): bucketId: -1014163439

As defined by several articles i use this code to construct my URI:

uri = MediaStore.Images.Media.INTERNAL_CONTENT_URI.buildUpon()
            .appendQueryParameter("bucketId", bucketId).build();

Then i launch it:

Intent intent = new Intent(Intent.ACTION_PICK,
            ImageHelper.getDirectoryUri(this, mImageId));
startActivityForResult(intent, GALLERY_TOKEN);

However this does not work. Just launches the top view of the gallery.

Using that mediascanner provides me an Uri, however the gallery refuses to launch into the specified folder. (I scan folder /sdcard/pictures/app/ for example The returned Uri is: content://media/external/file/10540 — Sam_Appstrakt, Mar 30 '12 at 09:20
like how we can fetch image/video data using bucket-id(folder-id)...how we can do same thing for audio files. — CoDe, Nov 10 '12 at 08:36
