Android open specific folder with gallery
<p>I've tried to open android 4.1 gallery with following code:</p>

<pre><code>String folderPath = Environment.getExternalStorageDirectory().toString() + "/" + GalleryHelper.FOLDER_NAME;
//        Uri targetUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI.buildUpon().appendQueryParameter("bucketId", GalleryHelper.BUCKET_ID).build();

final Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.setData(Uri.fromFile(new File(folderPath)));
intent.setClassName("com.android.gallery3d", "com.android.gallery3d.app.Gallery");
startActivity(intent);
</code></pre>

<p>Gallery opened, but it shows only default page, not folder. How can I change my code to open the folder?</p>
