how can I show a video thumbnail from a video path?

It is the default way to create a thumbnail.

For Mini Kind

Bitmap thumb;
//MINI_KIND, size:  512 x 384 thumbnail 
    thumb = ThumbnailUtils.createVideoThumbnail(filePath, MediaStore.Video.Thumbnails.MINI_KIND);
            img_tumbnail.setImageBitmap(thumb);

For Micro Kind

Bitmap thumb;
//MICRO_KIND, size: 96 x 96 thumbnail
thumb= ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MICRO_KIND);
img_tumbnail.setImageBitmap(thumb);

Also, you can use Glide for Url as well as Video path of Device.

Glide.with(context).with(this)
                    .asBitmap()
                    .load(videoFilePath) // or URI/path
                    .into(imgView); //imageview to set thumbnail to

also, you can resize thumbnail by using .override(50,50) with Glide.

How to get the video thumbnail path, and not the bitmap

First, you need to know the content uri of the file. If you have the file path, this shows you how to get the content uri.

public static String[] thumbColumns = { MediaStore.Video.Thumbnails.DATA };
public static String[] mediaColumns = { MediaStore.Video.Media._ID };

public static String getThumbnailPathForLocalFile(Activity context,
        Uri fileUri) {

    long fileId = getFileId(context, fileUri);

    MediaStore.Video.Thumbnails.getThumbnail(context.getContentResolver(),
            fileId, MediaStore.Video.Thumbnails.MICRO_KIND, null);

    Cursor thumbCursor = null;
    try {

        thumbCursor = context.managedQuery(
                MediaStore.Video.Thumbnails.EXTERNAL_CONTENT_URI,
                thumbColumns, MediaStore.Video.Thumbnails.VIDEO_ID + " = "
                        + fileId, null, null);

        if (thumbCursor.moveToFirst()) {
            String thumbPath = thumbCursor.getString(thumbCursor
                    .getColumnIndex(MediaStore.Video.Thumbnails.DATA));

            return thumbPath;
        }

    } finally {
    }

    return null;
}

public static long getFileId(Activity context, Uri fileUri) {

    Cursor cursor = context.managedQuery(fileUri, mediaColumns, null, null,
            null);

    if (cursor.moveToFirst()) {
        int columnIndex = cursor
                .getColumnIndexOrThrow(MediaStore.Video.Media._ID);
        int id = cursor.getInt(columnIndex);

        return id;
    }

    return 0;
}
