Answer 1

Loading images from internal store.Reading all folders which has images and videos using MediaStore class.

And returning result as ArrayList.

private fun getAllShownImagesPath(activity: Activity): ArrayList {

val uri: Uri
val cursor: Cursor
var cursorBucket: Cursor
val column_index_data: Int
val column_index_folder_name: Int
val listOfAllImages = ArrayList()
var absolutePathOfImage: String? = null
var albumsList = ArrayList()
var album: Albums? = null


val BUCKET_GROUP_BY = "1) GROUP BY 1,(2"
val BUCKET_ORDER_BY = "MAX(datetaken) DESC"

uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI

val projection = arrayOf(MediaStore.Images.ImageColumns.BUCKET_ID,
        MediaStore.Images.ImageColumns.BUCKET_DISPLAY_NAME,
        MediaStore.Images.ImageColumns.DATE_TAKEN,
        MediaStore.Images.ImageColumns.DATA)

cursor = activity.contentResolver.query(uri, projection, BUCKET_GROUP_BY, null, BUCKET_ORDER_BY)

if (cursor != null) {
    column_index_data = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA)
    column_index_folder_name = cursor
            .getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME)
    while (cursor.moveToNext()) {
        absolutePathOfImage = cursor.getString(column_index_data)
        Log.d("title_apps", "bucket name:" + cursor.getString(column_index_data))

        val selectionArgs = arrayOf("%" + cursor.getString(column_index_folder_name) + "%")
        val selection = MediaStore.Images.Media.DATA + " like ? "
        val projectionOnlyBucket = arrayOf(MediaStore.MediaColumns.DATA, MediaStore.Images.Media.BUCKET_DISPLAY_NAME)

        cursorBucket = activity.contentResolver.query(uri, projectionOnlyBucket, selection, selectionArgs, null)
        Log.d("title_apps", "bucket size:" + cursorBucket.count)

        if (absolutePathOfImage != "" && absolutePathOfImage != null) {
            listOfAllImages.add(absolutePathOfImage)
            albumsList.add(Albums(cursor.getString(column_index_folder_name), absolutePathOfImage, cursorBucket.count, false))
        }
    }
}
return getListOfVideoFolders(albumsList)
}

// This function is resposible to read all videos from all folders.

private fun getListOfVideoFolders(albumsList: ArrayList): ArrayList {
var cursor: Cursor
var cursorBucket: Cursor
var uri: Uri
val BUCKET_GROUP_BY = "1) GROUP BY 1,(2"
val BUCKET_ORDER_BY = "MAX(datetaken) DESC"
val column_index_album_name: Int
val column_index_album_video: Int

uri = android.provider.MediaStore.Video.Media.EXTERNAL_CONTENT_URI

val projection1 = arrayOf(MediaStore.Video.VideoColumns.BUCKET_ID,
        MediaStore.Video.VideoColumns.BUCKET_DISPLAY_NAME,
        MediaStore.Video.VideoColumns.DATE_TAKEN,
        MediaStore.Video.VideoColumns.DATA)

cursor = this.contentResolver.query(uri, projection1, BUCKET_GROUP_BY, null, BUCKET_ORDER_BY)

if (cursor != null) {
    column_index_album_name = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.BUCKET_DISPLAY_NAME)
    column_index_album_video = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA)
    while (cursor.moveToNext()) {
        Log.d("title_apps", "bucket video:" + cursor.getString(column_index_album_name))
        Log.d("title_apps", "bucket video:" + cursor.getString(column_index_album_video))
        val selectionArgs = arrayOf("%" + cursor.getString(column_index_album_name) + "%")

        val selection = MediaStore.Video.Media.DATA + " like ? "
        val projectionOnlyBucket = arrayOf(MediaStore.MediaColumns.DATA, MediaStore.Video.Media.BUCKET_DISPLAY_NAME)

        cursorBucket = this.contentResolver.query(uri, projectionOnlyBucket, selection, selectionArgs, null)
        Log.d("title_apps", "bucket size:" + cursorBucket.count)

        albumsList.add(Albums(cursor.getString(column_index_album_name), cursor.getString(column_index_album_video), cursorBucket.count, true))
    }
}
return albumsList
}
